A-GAGE® High-Resolution MINI-ARRAY®
2 System Overview
The A-GAGE® High-Resolution MINI-ARRAY® measuring light screen is ideal for applications such as on-the-fly product
sizing and profiling, edge-guiding and center-guiding, loop tensioning control, hole detection, parts counting and similar
uses.
A typical A-GAGE High-Resolution MINI-ARRAY system has five components: a high-resolution emitter/receiver pair, each
with quick-disconnect (QD) connectors; one of four compact control modules; and quick-disconnect cables to connect
them. Software is included to interface any PC-compatible computer (running Windows®1 XP, Vista, or 7) with the control
module for system configuration. A host computer or PLC may be used to control and/or receive input from the system.
Sensors are available in twelve array lengths from 163 mm to 1951 mm (6.4 in to 76.8 in), in 163 mm (6.4 in) increments. The
emitter has two columns of infrared LEDs spaced 5 mm (0.2 in) apart. The columns are separated by 7.5 mm (0.3 in) and are
staggered from each other by 2.5 mm (0.1 in). The receiver is configured opposite to the emitter, with the identical length
and beam spacing. This high-resolution sensor pair is capable of detecting a 12.7-mm long by 2.54-mm diameter (0.5 in by
0.1 in diameter) cylindrical rod (held perpendicular to the sensor). The sensors have a wide field of view and are easily
aligned, with a working range of 380 mm to 1.8 m (15 in to 6 ft).
Each of the four versatile microcontroller-based control modules are configured using a PC-compatible computer running
Windows XP, Vista, or 7, and the supplied software, via the built-in RS-232 interface.
2.1 System Features
Built-in features simplify the operation of the A-GAGE High-Resolution MINI-ARRAY system. High-resolution emitters and
receivers, available in twelve lengths, feature two closely spaced columns of beams to provide a precise, high-resolution
light screen for exacting applications. The Alignment routine automatically equalizes the excess gain of each beam for
reliable 2.5-mm (0.10-in) object detection throughout the array and stores this data in non-volatile memory. The Alignment
routine does not need to be performed again unless the sensing application changes, or if the emitter and/or receiver is
moved. Programmable beam blanking accommodates machine components or other fixtures that must remain in or move
through the light screen. Blanking may be set automatically as part of the initial setup, or by using the included
configuration software.
Built-in diagnostic programming and easy-to-see indicators on the sensors and the control module make alignment and
troubleshooting easy. The emitter has a red LED that signals proper operation. The receiver has three bright LEDs: green
signals that the sensors are properly aligned; yellow signals marginal alignment; and red signals misalignment or a blocked
condition. The control module has four status indicators: 3 red LEDs signal discrete output #1 conducting, Alarm output
(discrete output #2) conducting, and gate signal received; a green LED signals that the sensors are properly aligned. A
segmented LED Diagnostics Indicator provides detailed system status using single-digit codes; a period in the indicator
window indicates the presence of blanking. A key to the diagnostics codes is printed on the side of the control module for
simplified troubleshooting.
The A-GAGE High-Resolution MINI-ARRAY system provides a wide selection of sensing and output options, including:
measurement (scan analysis) modes and scanning methods that can determine the target object’s location, overall size,
total height or total width. Scanning may be continuous or controlled by a host process controller or a gate sensor. Up to 15
systems may be networked.

2.2 Supplied System Software
The supplied software program, used to configure each system control module, may be run on any PC running Windows®
XP, Vista, or 7. The menu-driven program walks the user through the many scanning and output options. After the desired
options are selected, the user can save the combination of selections in a Parameter Setup File (PSF), and store it in the
control module’s non-volatile memory. Any number of PSFs may be stored in the computer and recalled as needed.
The software also provides alignment and diagnostics routines. An Alignment screen displays the individual status of each
beam in the light screen, as well as the total number of beams in the system, and totals of beams blocked, made, and
blanked. Built-in system diagnostics can be used to assess emitter and receiver hardware errors.

3 Installation Instructions
3.1 Emitter and Receiver Mounting
Banner MINI-ARRAY emitters and receivers are small, lightweight, and easy to handle during mounting. The mounting
brackets (supplied) allow ±30° rotation.
From a common point of reference, make measurements to locate the emitter and receiver in the same plane with their
midpoints directly opposite each other. Mount the emitter and receiver brackets using the vibration isolators and M4 Keps
nuts (all supplied). Standard M4 or #8-32 bolts may be substituted (and the vibration isolators eliminated) in situations
where the emitter and receiver are not subjected to shock or vibration forces. While the internal circuits of the emitter and
receiver are able to withstand heavy impulse forces, the vibration isolators dampen impulse forces and prevent possible
damage due to resonant vibration of the emitter or receiver assembly.

1. Mount the emitter and receiver in their mounting brackets; see Figure 6 (p. 8).
2. Position the red lenses of the two units directly facing each other. The connector ends of both sensors must point in
the same direction.
3. Measure from one or more reference planes (for example, the floor) to the same points on the emitter and receiver to
verify their mechanical alignment. If the sensors are positioned exactly vertical or exactly horizontal, a carpenter’s
level may be useful for checking alignment. Extending a straight-edge or a string between the sensors may help with
positioning.
4. Also check by eye for line-of-sight alignment.

3.3.2 Inputs
System Power: Connect a source of 16 V dc to 30 V dc, rated at 1 amp or greater, to control module terminals #1 (+) and #2
(-). Connect a good earth ground to terminal #3 to provide electrical and RF noise immunity to the System.
Note: Remove power before making other connections to the controller.
Gate Signal: A source of 10 V dc to 30 V dc switched to terminals #12(+) and #13(-) provides a gating input (if required). The
gating voltage typically is switched by the open-collector output transistor of a dc sensing device. The gate signal controls
scanning when one of four Gate options is selected in the Control Mode Selection menu of the PSF configuration routine
(see Control Mode Selection (p. 19)) .
Align: A source of 10 V dc to 30 V dc switched to terminals #14(+) and #15(-) provides a remote means of running the
automatic alignment and blanking routines. The switch sequence is identical to the procedure described in Push-Button
Alignment Routine (p. 14) for the Alignment switch on the front of the control module.

Perform the Ping routine during system configuration, and before any Diagnostic, Alignment, or Edit routine. The routine
polls all control modules on the communications line (one, in the case of the standard RS-232 line, or up to 15 modules, on
an RS-485 circuit). It then is used to select an individual control module for configuration or alignment.
1. If needed, apply power to the system control module and allow the system to complete its power-up routine.
2. Press F5 or access the MINI-ARRAY menu.
3. Select Ping to perform the Ping routine.
All connected control modules identify themselves with an ID value and baud rate; the routine takes approximately
15 to 20 seconds. After the Ping is performed, all valid control module ID values display in a chart on the screen,
under their appropriate baud rates. Control modules are identified in the chart as X.
Figure 13. Screen showing the result of a completed Ping routine
4. Point to a valid ID and click to select a control module.
System Diagnostics, Alignment, or Edit routines may now be performed for the selected control module.

4.1.2 Factory Settings
Of the 15 available control module ID values (A through O), the factory software setting is A. Selectable communication
baud rates are 9600, 19200, and 38400; the factory setting is 9600. See Selected Controller and Serial Communication (p.
18) for information on changing these settings.
4.2 System Alignment
The emitter/receiver pairs have a wide field of view and are easy to align. The recommended distance between the emitter
and receiver ranges from 380 mm to 1829 mm (15 in to 72 in). Shorter sensor separation can be achieved; consult Banner
Engineering for details.
Perform the Alignment process at System installation and repeat it every time one or both of the sensors is moved.
Alignment of the System can be specified automatically using either the Alignment routine of the configuration software or
the Alignment switch on the control module’s front panel.
The System also may be aligned remotely, using pins 14 and 15 on the terminal block. Apply 10 V dc to 30 V dc power to
the pins to approximate the push-button procedure. For example, apply input signal for 3 seconds to access Alignment
mode.
1. Make sure the sensors have been wired as shown in Wiring (p. 9).
2. Apply power to the control module via terminals #1 and #2 (16 V dc to 30 V dc).
The Diagnostics Indicator shows the sensors going though a power-up test: first the receiver, then the emitter. After
the sensors have been tested and the System is ready for service, the Diagnostics Indicator shows — or —.; see
figure.

4.2.1 Push-Button Alignment Routine
Re-align the System at installation or whenever the emitter and/or receiver is moved.
1. Press the Alignment switch on the control module front panel for 3 seconds.
The letter A displays on the Diagnostics Indicator; the System is learning a clear condition.
2. Rotate the sensors as required (but do not change the distance between them).
When the green Alignment LED is displayed on the control module and receiver, the sensors are adequately aligned.
3. To leave Alignment mode, press the Alignment switch for 3 seconds.
During the alignment procedure, the System polls each receiver channel to measure excess gain and performs a coarse
gain adjustment. When the System exits the alignment procedure, each channel’s signal strength is stored in non-volatile
memory. The System is now ready for operation and does not require re-alignment unless the emitter or receiver is moved.
4.2.2 Software Alignment Routine
The green LED indicator on the receiver and also on the control module continuously displays Alignment status. When all
unblanked beams are clear, the green Alignment indicators are ON. To better understand blocked, clear, and blanked
beams, launch the Alignment routine (press F8 or select Alignment under the MINI-ARRAY menu). The screen shows the
state of all of the beam channels, grouped into sets of 16.
Key information provided on the Alignment screen is the sensor size, plus the number of beams blocked, made, and
blanked. The sensor size is given the title of Total; this refers to the total number of beam channels in the array. The number
of beams blocked is a running total of blocked beams, excluding any blanked beams. The Made value is a count of
unblocked beams. The Blanked value is a count of the number of beam channels that are blanked (channels that are
ignored for measurement mode applications).

The Alignment screen provides the following functions: Start, Stop, Step, Clear Blanking Fields, Restore Control module
Settings, Auto Blanking, Abort Auto Blanking, Save to File, Read From File, Cancel, OK, and Edit. To access any of these
sub-routines, first click Stop, then the selected option.
Start causes the control module to continuously scan and report All Channel Data. This data is used to update the state of
each beam channel.
Stop causes the control module to stop scanning.
Step produces one scan and then stops until another command is issued.
Clear Blanking Fields is a quick way to remove blanking specifications.
Restore Control Module Settings recalls the blanking specifications in effect prior to Alignment/Blanking being entered.
Auto Blanking is used to scan and determine which beams are blocked; blocked beams automatically become blanked
beams. The Auto Blanking values can then be Accepted or Aborted.
Edit is used to control the blanking specifications of any channel manually. This is useful for adding any number of blanked
beam channels above and/or below a blanked object to allow for vibration or other movement of the object to be ignored.
Blanking specifications can be saved and read from a computer file using Save To File and Read From File commands.
Figure 15. Alignment screen
4.2.3 Blanking
If a machine fixture or other equipment will continuously block one or more beams, the affected beam channels may be
blanked. The Blanking option causes the control module to ignore the status of blanked beams for measurement mode
calculations. For example, if a machine fixture blocks one or more beams during System operation, the output data will be
incorrect; if beams blocked by the fixture are blanked, the output data will be correct. Blanking may be configured using the
push-button Alignment switch on the control module, or by using the System software and a computer.
Push-Button Blanking Setup Routine
To specify blanking using the control module’s Alignment switch, position the object or part to be ignored in the path of the
beams before beginning the Alignment routine.
1. Press the Alignment switch for 3 seconds.
The Diagnostics Indicator shows the letter A.
2. Press the Alignment switch momentarily (about 0.5 seconds maximum).
The Diagnostics Indicator shows the letter b to indicate it is ready to learn the blanking pattern.
3. Press the Alignment switch momentarily (about 0.5 seconds maximum) to set the blanking fields.

4.3 Programming Control Module Response
Use the Parameter Setup File (PSF) Configuration routine to configure the control module for a specific application. After
performing the Ping routine to select a control module, access the PSF Configuration screen by selecting Edit PSF (F4) from
the MINI-ARRAY menu. The Edit PSF process may also be performed with no control module selected, to configure and
save a PSF for multiple control modules. In such a case, some fields on the PSF Configuration screen will not be
accessible.
The process of configuring the control module involves selecting among options for each of the parameters listed in this
section, including serial communication, control mode, scanning method, scan analysis mode, serial transmission, and
analog/discrete outputs. The resulting combination of options causes the control module to react as required for the
application, to changes in the light screen.
The configuration process produces a Parameter Setup File (PSF). PSF files may be saved and retrieved as computer files
via File Save PSF and File Retrieve PSF (see Saving and Recalling PSF Files (p. 25)) . After it is configured, a PSF may be
sent to the control module via the Send PSF command. The PSF currently loaded into the control module may be displayed
by using the Upload PSF command.

Baud Rate is the data communication rate between the control module and the computer used for configuration and also
the process controller. Choose from three values: 9600, 19200, and 38400.
Parity: Select Odd, Even, or None. All controllers on one EIA-485 party line should have the same parity settings.
4.3.2 Control Mode Selection
The control mode determines the method used to control scanning of the light screen array. Choose from three main
control modes:
• Continuous Scan Mode
• Serial Host Command Mode
• Gate Mode, which has four options
In Continuous Scan mode, the control module begins a new scan as soon as it updates the outputs from the previous scan.
This is the fastest scan control method; it is used in most analog output applications and whenever continuous updating of
the outputs is acceptable.
Host mode allows the control module to communicate with a host computer or control module via RS-232 (all models) or
RS-485 (discrete-output models only) serial protocol. The host directs the control module to scan on demand and receives
the output data from the control module in binary or ASCII form. Baud rates of 9600, 19200, and 38400 are selectable in the
Serial communications menu. See Additional Information (p. 35) for more information on Host mode data format.
Gate mode activates an optically isolated external Gate input between terminals 12 (+) and 13 (-) of the control module. The
Gate input has impedance of 7.5 kΩ and accepts a 10 V dc to 30 V dc signal. A dc device such as a photoelectric sensor or
optical encoder typically supplies the Gate input. Gate input signals must be greater than 150 microseconds in duration; the
time between successive Gate inputs must be greater than the minimum scan time for the light screen array (see Scanning
Method (p. 19) for scan time information).
Gate mode has four options:
• Gate ON: the control module will scan as long as the gate is active.
• Gate OFF: the control module will scan whenever the gate is not active.
• Gate ON/OFF: the control module will scan once for each gate transition from ON to OFF.
• Gate OFF/ON: the control module will scan once for each gate transition from OFF to ON.
4.3.3 Scanning Method
The control module may be configured for one of three scanning methods:
• Straight Scan
• Single-Edge Scan
• Double-Edge Scan
Straight scan is the default mode in which all beams are scanned in sequence from the bottom end (cable end) to the top
end of the array. This scanning method requires the longest scan times and provides the smallest object detection size (2.5
mm, 0.1 in diameter).
Single-Edge scan is used to measure the height of a single object. A good application for this scanning method is box
height measurement. For Single-Edge scan, the system always activates the first beam channel (nearest the cable end, or
bottom). If the first beam is blocked, the sensor performs a binary search to hunt for the last beam blocked. Single-Edge
scan works as follows:
1. The receiver scans only the bottom beam until that beam is blocked.
2. When the bottom beam is blocked, the sensor looks to see whether the middle beam is blocked or made
(unblocked).
3. If the middle beam is made (unblocked), the sensor checks the bottom quarter beam; if the middle beam is blocked,
the sensor checks the top quarter beam. This is called a binary search.
4. This routine continues to narrow the field until the edge is found.

Figure 20. Finding an Edge Using a Binary Search
Note that the receiver always checks the bottom beam first, and only if that beam is blocked does the binary search
continue. Therefore, Single-Edge scan will not work in instances where an item that does not block the first beam is to be
measured. Single-Edge scan is also ineffective if the object does not present a continuous blocked pattern. In other words,
Single-Edge scan is used for single, solid objects that block the first beam.
Double-Edge scan is used to detect two edges of a single object, for example, box width measurements. Double-Edge
Scan requires the selection of a step size: 2, 4, 8, 16 or 32 beams. The sensor uses the steps to skip over beams. DoubleEdge scan works as follows:
1. The sensor activates beam #1 (the beam closest to the sensor cable end).
2. The sensor activates the next beam, determined by the step size. For example, if the step size is 2, beam #3 is next;
if the step size is 8, beam #9 is next.
3. As long as the activated beam is unblocked (or made), the sensor continues the stepping routine until a blocked
beam is found.
4. When a blocked beam is found, a binary search is conducted to find the object’s bottom edge.
5. When the bottom edge is found, the sensor begins stepping again through the array until the sensor finds the next
unblocked beam.
6. A binary search is again performed to find the second edge.
Note that this scanning method sacrifices object detection size for speed. Similar to Single-Edge scan, Double-Edge scan
has some restrictions: the object should provide a solid obstruction; the size of the object will determine the maximum step
size.

4.3.4 Scan Analysis Mode Selection
The control module may be programmed, if desired, for any
one or two of seven Scan Analysis (measurement) Modes.
Each selected mode may be assigned individually to an
output (see section Analog Output Configuration (Analysis
Mode Assignment) (p. 22) or Zero Value (p. 23)). The
beams in the array are numbered in sequence, with beam
#1 located at the cabled end of the emitter and the receiver.
Beam Location Modes
• First Beam Blocked (FBB): The control module
identifies the location of the First Beam Blocked.
• First Beam Made (FBM): The control module
identifies the location of the First Beam Made
(unblocked).
• Last Beam Blocked (LBB): The control module
identifies the location of the Last Beam Blocked.
• Last Beam Made (LBM): The control module
identifies the location of the Last Beam Made
(unblocked).
• Middle Beam Blocked (MBB): The control module
identifies the location of the Middle Beam Blocked,
midway between the first and last beams blocked.
Beam Total Modes
• Total Beams Blocked (TBB): The control module
totals the number of blocked beams.
• Total Beams Made (TBM): The control module totals
the number of made (unblocked) beams.
• Contiguous Beams Blocked (CBB): The control
module identifies the largest number of
consecutively blocked beams.
• Contiguous Beams Made (CBM): The control
module identifies the largest number of
consecutively made beams.
• Transitions (TRN): The control module counts
changes from blocked to clear and clear to blocked.
For instance, if beams 6-34 are blocked, then there
is a clear-to-blocked transition from beam 5 to beam
6, and a blocked-to-clear transition from beam 34 to
beam 35. Transition mode can be used to count
objects within the array.

Figure 21. Examples of MINI-ARRAY Scan Analysis Modes
The Analysis Mode(s) programmed may be assigned to any
one of the available outputs. Each output can be set for
MEAS1, MEAS2, MEAS1 Inverted, or MEAS2 Inverted.
4.3.5 Analog Output Configuration (Analysis Mode Assignment)
Analog outputs #1 and #2 may each be assigned to one of the analysis modes. When the selected Scan Analysis Mode
involves first or last beam blocked or made (unblocked), the assigned output will vary in proportion to the beam number
identified during a scan. When the Scan Analysis Mode involves total beams blocked or made, that assigned output will
vary in proportion to the total beams counted during a scan.
Note that the menus used for assignment of the Scan Analysis Modes to the analog outputs include two Inverted
selections. When either MEAS1 Inverted or MEAS2 Inverted is selected, that analog output will decrease as the
measurement mode value increases. An inverted output is at full scale (Span value) when the scan analysis value is zero;
and at maximum scan analysis value, the output is at the Null value.
The Null/Span Configuration screen , may be used to adjust the zero and full scale reading for either analog output. To
display the Null/Span Configuration screen, click on the Null/Span button at the bottom of the PSF Configuration screen.
Each output is independent and must be adjusted separately. Adjust the Null and Span values either by moving the slide
bars, or by entering a new value on the keyboard.
Note: When in the Null/Span screen, the controller has a diagnostic code of 8.

Adjust the Null and Span ranges as follows:
1. To read the new values on the meter, click Null or Span Update.
2. Click OK to save the new settings and return the program to the PSF Configuration screen. Clicking Cancel returns
the program to the previously saved null and span settings.
Note: Null and Span are factory set to specified values and usually require no changes.
Scan # provides a way to smooth output response and avoid unstable analog output conditions. The menu allows selection
of 1 to 9 scans. For analog outputs, if scan # is set at more than 1, the scan analysis value is averaged for all of the selected
number of consecutive scans, preventing dips and spikes in the outputs.
For total beam values (TBB and TBM analysis modes), programming of blanked beams will affect the proportional analog
outputs. Blanked beams are ignored both in the number of blocked or made beams and the total number of beams. For
example, if a 64-beam array has 20 blanked beams and 22 of the remaining 44 beams are blocked, the output values will be
at mid-range.
4.3.6 Zero Value
Zero value is used to specify the analog output when the measurement mode value is zero. Select an analog output of Last,
Null, or Span.
Last: Output holds the last non-zero value before the light screen became clear.
Null: Provides the minimum value.
Span: Provides the maximum value.
4.3.7 Discrete Output Configuration (Analysis Mode Assignment)
Discrete outputs #1 and #2 (Alarm) may each be individually assigned to one of the Scan Analysis Modes programmed in
Scan Analysis Mode Selection (p. 22).
www.bannerengineering.com - Tel: + 1 888 373 6767
23
A-GAGE® High-Resolution MINI-ARRAY®
Figure 23. Assigning an Analysis Mode to each Discrete output (PSF Configuration screen); Alarm and Trigger output options are available only for Discrete
Output #2
Next to each discrete output assignment menu are Low Set Point and High Set Point boxes. The number in each box
identifies a beam in the array (beam #1 being closest to the cabled end of the emitter and the receiver). Change the Low
and High Set Points by clicking on a box and entering a new number.
When the selected Scan Analysis Mode involves first or last beam blocked or made (unblocked), the assigned output will
energize when the beam identified during a scan falls within the range of the set points. When the Scan Analysis Mode
involves total beams blocked or made, that assigned output will energize when the value of total beams counted during a
scan falls within the range of the set points.
Note that the menus used for assignment of the Scan Analysis Modes to the discrete outputs include two Inverted
selections. When either MEAS1 Inverted or MEAS2 Inverted is selected, that discrete output will de-energize (turn OFF)
whenever a scan analysis value falls within the range of the set points.
Hysteresis values for each end of the set point range may also be set. Hysteresis determines the amount of change that
must occur at each set point (High and Low) to cause the associated output to change state. Hysteresis prevents unstable
output conditions when the scan analysis value exactly matches one of the set points. The default hysteresis setting is one
beam less than the Low Set Point and one beam more than the High Set Point.
Scan # provides another way, in addition to hysteresis settings, to smooth output response. Outputs are updated only after
the selected number of identical (within the hysteresis limits) scans. The menu allows selection of 1 to 9 scans. For discrete
outputs, the scan analysis value must stay either inside or outside the hysteresis limits for all of the selected number of
consecutive scans, in order for the output to respond.
Alarm and Trigger
Discrete output #2 (only) has two additional options: Alarm and Trigger.
Alarm: Output #2 energizes whenever the System detects a sensor error (such as a disconnected cable) or whenever the
excess gain of one or more beams becomes marginal.
Trigger: can be used to gate a second control module when Continuous Scan Method is also used. When the control
module is in straight scanning mode, Trigger Channel Number defines the beam number during a scan at which the trigger
output will occur. The Trigger output is a 100 microsecond (0.0001 second) pulse. If the control module is set for single or
double edge scan, the Trigger pulse comes at the end of the scan (Trigger Channel Number is ignored).
4.4 Serial Communication with a Host Controller
The control module communicates with a host process controller via RS-232 or RS-485 protocol and at the baud rate
specified in the Serial Communications box. The System provides a number of data transmission options.
4.4.1 Serial Data Transmission
The serial transmission portion of the PSF Configuration screen activates the serial port(s), specifies the data format, and
provides data suppression options. These settings are required to allow a control module to communicate with a host
computer or process controller. If No Serial Communication is selected (the default setting), the serial port(s) will not
transmit sensing data.
Measurement Mode Result: Data transmitted are the values output for the Scan Analysis Mode selections. Up to two Scan
Analysis Mode selections can be active.
24
www.bannerengineering.com - Tel: + 1 888 373 6767
A-GAGE® High-Resolution MINI-ARRAY®
ALL Mode: The status of each beam in the light screen array is transmitted for each scan. In ALL mode, blanked channels
are transmitted as unblocked (or clear) beams.
Max Meas Mode: The control module records the maximum measurement value registered while the light screen is blocked.
That data may be transmitted to the host either when the array is clear at the end of the sensing event (select Send On
Clear), or when prompted by the host (select Send On Request). This mode reduces the amount of serial data sent.
4.4.2 Transmission Type
Transmission type defines the format in which data is sent. The ASCII option causes the control module to send data in
three ASCII-coded bytes. The Binary option causes data to be sent in binary format, reducing the amount of data per
measurement mode from three bytes to two. For more information on the data formats, refer to Additional Information (p.
35).
4.4.3 Serial Options
The Serial Options box provides two options: Suppress Clear Data and Suppress Header.
Suppress Clear Data provides one method to reduce the amount of data being transmitted by the control module,
accomplished by not sending data when no object is detected. The control module transmits serial data only when one or
more unblanked beams of the light screen array are blocked. When the array goes from blocked to clear, data is sent one
additional time, indicating the clear condition.
Suppress Header is used to prevent transmission of the three-byte identification string (“header string”) associated with
either ASCII or Binary data formats. The header string consists of two bytes at the start of the data, and a termination byte
to mark the end of the serial transmission. See Additional Information (p. 35) for more information on serial data formats.
4.5 Transfer of PSF to the Control Module
After making all of the selections in the PSF Configuration screen, send the PSF to the control module by clicking Send
PSF. This command loads the PSF into the non-volatile memory of the control module, and automatically overwrites the
current PSF. The program confirms that the PSF was accepted, or notifies the user of changes required to the PSF.
To check the values of the PSF currently loaded into the control module, select Upload PSF. The current PSF displays on
the PSF Configuration screen.
4.5.1 Saving and Recalling PSF Files
To place the displayed PSF into a file that can be retrieved at any time:
1. Click File Save PSF.
2. When asked if you want to save the PSF to a file, select Yes. A subscreen titled FileSave displays.
3. Overtype *.psf in the File Name entry box with the name of the file to be stored (up to 8 characters), plus the .psf
extension.
4. Click OK (or press Enter).
The PSF is stored on the selected drive (default is c:) and the program automatically returns to the PSF Configuration
screen.
To retrieve a filed PSF:
1. Click File Retrieve PSF. The FileBox subscreen displays.
2. Select the desired PSF from the File Name list.
3. Click OK (or press Enter).
The selected PSF loads to the PSF Configuration screen, and it can then be loaded into the controller using the Send PSF
command.
4.5.2 PSF Output Analysis
To view activity in the array in response to the currently loaded PSF:
1. Select Execute. The Measurement Output screen displays.
www.bannerengineering.com - Tel: + 1 888 373 6767
25
A-GAGE® High-Resolution MINI-ARRAY®
Figure 24. Measurement Output Screen
2. Select Run. The table displays the status for the selected measurement mode(s), including the Present value and the
High and Low values for the Run period.
3. Select Stop to freeze the data.
4. Select Step to initiate a single scan of the array to simulate a snapshot of what is viewed by the array at the instant
that Step is selected.
Use of the Execute command is beneficial for testing the response of a gated system. Run simulates the Continuous
Scanning mode, and Step simulates a gate input command.
4.5.3 Quit and Exit
To close the PSF Configuration screen, select either Quit or Exit. Selecting Quit erases the Edit PSF Screen and sends the
user back to the Main Window; the present PSF Screen values are not retained. The Exit command is similar to the Quit
command, except the user is prompted to save the configuration values to a parameter setup file (PSF).

8 Additional Information
8.1 Host Mode Command String
As discussed in this manual, the control module has three control mode options: continuous, gate, and host. Host mode
requires a serial transmission string from a separate device, typically a PC or process controller. The serial transmission
medium can be either RS-485 or RS-232.
When Host control mode is selected, the host process controller initiates scans using a command string. The command
string is a three-byte message, consisting of:
• Control byte with decimal value 248
• Controller ID (the identification of a specific control module on the string, indicated by one of 15 ASCII letters A
through O, and specified in the PSF)
• Scan initiation byte (ASCII letter S)
The command string is further defined as follows:
/*the below C code will define an array called msg that will contain the Host Scan Command */
unsigned char msg[3]; /*declare three byte unsigned character array using C language */
msg[0]=248; /*control byte */

msg[2]=83; /*assume initiation byte which is the ASCII letter S */
The host transmits this three-byte message at the defined baud rate. The format is one start bit, one stop bit, even parity,
and eight data bits. When the control module receives this message, it initiates a scan (assuming Host mode is selected)
and then updates its outputs as required. The control module then waits for the next Host Command message before
initiating another scan.
8.2 Serial Data Format and Header String
The programmed measurement mode or modes determine the type of information that is serially transmitted. For example if
Meas1 is set for FBB and Meas2 is set for LBB, then the data transmitted to the host contains the values of the first and last
beam blocked. The All measurement mode provides the status of all beams to the host.
In addition to measurement mode information, the data transmission also contains a two-byte start string and a termination
byte. The start string consists of a first byte that does not change, followed by the controller ID. The first byte value is a hex
1C or 28 decimal. At the end of the string, the control module will place a termination byte. The termination bye is the ASCII
character for a linefeed (hex value 0A). These three bytes collectively are called the Serial Header string.
8.2.1 ASCII Format Data Transmission
There are two ways to use ASCII format to represent data. The one used depends upon which measurement modes are
selected.

For ALL measurement mode, each data byte is presented in an
eight-bit ASCII format that conveys the status of four consecutive
channels (four consecutive beams). Each subsequent byte
conveys the status of the next four channels, until the status of
every channel is reported. The allowable data values for All
measurement mode are ASCII numbers 0 to 9 and ASCII letters A
to F. In the table, a 0 represents an unblocked beam channel, and
1 represents a blocked channel.

For example, assume that a 64-channel system has been configured for the All measurement Serial transmission option.
Channels 1 through 4 are blocked, as is channel 63. The serial string starts with 0x1c, and the ID (assume an ‘A’) followed
by 16 ASCII values and terminated with 0x0A. The string would appear:
0x1c, ‘A’, ‘F’, ‘0’,’0’, ‘0’,’0’, ‘0’,’0’, ‘0’,’0’, ‘0’,’0’, ‘0’,’0’, ‘0’,’0’, ‘0’,’4’, 0x0a
The string shows that beams 1 through 4 are blocked, as is beam 63. All other beams are unblocked. If the user had
requested suppression of the header, then 0x1c, ‘A’, and the 0x0a would have been deleted.
For transmitting Measurement mode data, use three ASCII bytes to represent each measurement mode. For example, if
Meas1 is FBB, Meas2 is LBB, the measured values are 6 and 120, and the controller ID is B, the data string is as follows:
0x1c ‘B’, ‘0’, ‘0’, ‘6’, ‘1’, ‘2’, ‘0’, 0x0a
As with ALL mode, the header and clear data could be suppressed. For clear data suppression, the control module sends
the status of a clear condition only on the first clear scan. After that, the control module will continue to scan but will not
transmit data until the sensor is again blocked.
8.2.2 Binary Format Data Transmission
Similar to ASCII format, binary format may be used to represent data in two ways. One method involves the All Data
transmission mode; the other, Measurement mode.
For All Data transmission mode, the control module represents the status of eight consecutive data channels for each byte.
Each bit of each byte is directly related to the status of an individual channel. The first data byte represents channels 1
through 8; the second data byte represents channels 9 through 16. The bit pattern for the first and second data bytes is as
shown in the table.

For each bit position, 1 represents a blocked beam and 0 represents an unblocked beam.
For example, for a 64-channel system with beams 1-6 blocked, beam 43 blocked and beams 62-64 blocked, the data
transmitted from control module ‘A’ is as follows:
0x1c, ‘A’, 0xFC, 0x00, 0x00, 0x00, 0x00, 0x20, 0x00, 0x07, 0x0A
This string would have the start byte, controller ID, followed by the eight data bytes and terminated with the 0x0A. The
header bytes may be suppressed if necessary.
For Measurement mode analysis, the binary format uses two data bytes for each measurement mode. (If we have one
measurement mode, then there are two data bytes. For two measurement modes, there are four data bytes.)
For example, assume that control module B is configured for one measurement mode (FBB), and the value is 78. The string
from the control module is as follows:
0x1c, ‘B’, 0x00, 0x4E, 0x0A.
(a total of five bytes)
or
0x00, 0x4E
(a total of two bytes with Suppress Header option)
Now assume that control module B is configured for FBB and LBB with values of 74 and 303, respectively. The string from
the control module is as follows:
0x1c,’B’, 0x00, 0x4A, 0x01, 0x2F, 0x0A
(a total of seven bytes)
or
0x00, 0x4A, 0x01, 0x2F
(a total of four bytes with Suppress Header option)
8.3 Max Meas Mode Command String
Max Meas Mode causes the control module to retain the maximum measurement values for a given object. These values
are transmitted either immediately after the control module is cleared or when prompted by the Host. The Max Meas Mode
Command String is a four-byte string that appears as follows:
• Control byte with decimal value 248
• Controller ID (one of 15 ASCII letters A through O, as specified in the PSF)
• Max Meas Command Transmit (ASCII letter T)
• Termination byte with decimal value 13

The command string is further defined:
/*the below C code will define an array called msg which will contain the Max Meas Mode Command String*/
unsigned char msg[4]; /*declare four byte unsigned character array using C language */
msg[0]=248; /*control byte */
msg[1]=65; /*assume the controller ID is the letter A */
msg[2]=84; /*assume initiation byte which is the ASCII letter T */
msg[3]=13; /*termination byte */
When the host sends this string, the control module sends the maximum values stored from the previous scanned object. If
the sensor is presently scanning an object when the message is sent, the control module gives the maximum values for the
present object.
8.4 Glossary
Blanked Beam
A beam that is ignored by the receiver, as a result of a blanking program being applied to it. Beams (or
groups of beams) are blanked when a component or fixture will remain in or move through the light
screen array; blanking the affected beams prevents the component or fixture from causing false
outputs.
Blocked Beam
A beam that is obstructed between the emitter and the receiver, and is not blanked.
Clear Beam
A beam that runs unobstructed from the emitter to the receiver (same as a made or unblocked beam).
Excess Gain
A measurement of the amount of light falling on the receiver from the emitter over and above the
minimum amount required for operation. A-GAGE High-Resolution MINI-ARRAY emitters and receivers
automatically perform an Alignment procedure to equalize the amount of excess gain at each element
along the array.
Host
A computer or process controller that controls and receives input from the High-Resolution MINIARRAY System, and/or other equipment and systems within a factory.
Made Beam
A beam that runs unobstructed from the emitter to the receiver (same as an unblocked or clear beam).
Unblocked Beam A beam that runs unobstructed from the emitter to the receiver (same as a made or clear beam).
