With the ability to connect to a PC serial port or microcontroller and optional hardware flow control, this is the most versatile header available on the GTT50A. Table 4: Extended Communication/Power Pinout Pin 6 5 4 3 2 1 Function RTS CTS Gnd Tx Rx Vcc Figure 9: Extended Communication/Power Header Voltage is applied through pins one and four of the header, please reference electrical specifications before applying power. Pins two and three are reserved for serial transmission using either RS-232/TTL levels, depending on what model has been ordered. Finally, pins five and six are used for optional hardware flow control. The Serial Molex 22-04-1061 style header used can be mated to a number of connectors, including a 22-01-1062. 4.3 Mini-B USB Communication Connector USB protocol offers an easy connection to any host computer. The simple and widely available protocol can be accessed using the familiar Mini-B USB connector to fulfill communication needs. Table 5: Mini USB Pinout Pin 1 2 3 5 Function Vcc DD+ Gnd Figure 10: Mini USB Connector The USB model can be connected to virtually any USB host using the appropriate cable; however, additional power must be supplied through the alternate power header. Most commonly used with a PC, this connection creates a virtual com port that offers a simple power solution with a familiar communication scheme. GTT50A Hardware Manual 6 Alternate USB Communication Header Some advanced applications may prefer the straight four pin connection offered through the optional Alternate USB Header. The Alternate USB Header may be added to the USB model for an added charge as part of a custom order. Please use the Contact section to reach Sales for additional details.

To install or update the drivers installed on your PC, locate the GTT50A in your device manager, right click its’ icon, select Update Driver Software, and manually point to the unzipped driver file. 4.4 I2C Communication/Power Header A dedicated I2C header is available on all GTT50A models and provides the most basic protocol connection to the unit. 2 Table 6: I C Communication/Power Pinout Pin 1 2 3 4 2 Function Vcc SCL SDA Gnd Figure 11: I C Communication/Power Header Voltage is applied through pins one and four of the header, please reference the electrical specifications before applying power. Pins two and three are reserved for I2C clock and data signals respectively, both of which should be pulled up to five volts using a resistance between one and ten kilohms. The Tyco 640456-4-LF style header used can be mated to a number of connectors, including Molex 22-01-3047. 7 GTT50A Hardware Manual 4.5 Alternate Power Connector The Alternate Power Connector provides the ability to power the GTT50A using a second cable. This connection is required for USB protocol due to the power requirements of the GTT50A. Table 7: Alternate Power Pinout Pin 1 2 3 4 Function Vcc Gnd Gnd NC* Figure 12: Alternate Power Connector The standard Tyco 171825-4 style header is particularly useful for connecting to an unmodified floppy power cable, a 171822-4 for example, from a PC power supply for a simple bench power solution. *Note: When using a –VPT model, it may be desirable to input power to the GTT using the floppy power cable 12V connection. Please Contact a friendly Matrix Orbital support representative for modification details. 4.6 RS422 Header RS422 communication provides an industrial alternative to the standard RS232 communication protocol. Rather than single receive and transmit lines, the RS422 model uses a differential pair for each receive and transmit signals to reduce degradation and increase transmission lengths. Table 8: RS422 Pinout* Pin 1 2 3 4 5 6 Figure 13: RS422 Header Function Vcc Tx (A) Inv Tx (B) Inv Rx (Z) Rx (Y) Gnd The six pin RS422 Header offers a power and ground connections at either end, and two differential pair communication lines in the middle. Regular and inverted lines, labelled A/B and Z/Y, are provided for receive and transmit signals. The standard Tyco 282834-6 style header populated is best mated to a sized 16 to 30 on the American Wire Gauge connections that are secured via the header screws. *Note: RS422 pinout was reversed at PCB Rev2.1. GTT50A Hardware Manual 8 4.7 Mass Storage Mini-B USB Header The GTT50A comes with a secondary Mini-B USB connector to access the SD memory card as a mass storage device for easier access to the files contained on the card. Table 9: Mass Storage USB Pinout Pin 1 2 3 5 Function Vcc DD+ Gnd Figure 14: Mass Storage USB Connector The mass storage selector must be placed on the pins labelled “A” to use this function, please refer to the Mass Storage Mode section for further information. Alternate USB Mass Storage Header Some advanced applications may prefer the straight four pin connection offered through the optional Alternate Mass Storage Header. The Alternate Mass Storage Header may be added to the GTT50A as part of a custom order. Please use the Contact section to reach Sales for additional details. Mass Storage Mode Placing a jumper on the USB mass storage selector labelled ”A”, the unit will appear to any PC as a mass storage device when powered, giving you access to the contents of the SD memory card directly. Please note, the speed of data transfers in mass storage mode is limited, and is only intended to be used in situations where an external SD memory card reader is not available. SD Memory Card The SD Memory Card is used to store all user fonts, bitmaps, 9-slices, animations and start-up settings. The start-up settings are stored in a binary file called AUTOEXEC. This file contains a simple stream of characters stored just as they would be if they were sent to the display at runtime, this will store all the commands to change the initial settings for your application. Start-up settings are stored in this location alone; therefore, simply removing the AUTOEXEC file will restore the display to factory defaults. Please refer to the Protocol Manual at http://www.matrixorbital.ca/manuals/GTT Series/ for a complete list of available commands executable not only at start up but runtime as well. 9 GTT50A Hardware Manual 4.8 General Purpose Outputs A unique feature of the GTT50A is the ability to control relays* and other external devices using either one of six General Purpose Outputs. Table 10: GPO Pinout Pin 1 2 3 4 5 6 7 8 Figure 15: GPO Header Function Gnd GPO 1 GPO 2 GPO 3 GPO 4 GPO 5 GPO 6 Vcc Pin 8 9 10 11 12 13 14 16 Function Gnd Gnd Gnd Gnd Gnd Gnd Gnd Gnd Each can source up to 15mA of current at five volts when on, or sink 15mA at zero volts when off. The two row, fourteen pin header can be interfaced to a number of female connectors to provide control to any peripheral devices required. 4.9 Keypad Header To facilitate user input, the GTT50A provides a Keypad Connector which allows a matrix style keypad of up to twenty-five keys to be directly connected to the display module. Key presses are generated when a short is detected between a row and a column. When a key press is generated, a character specific to that key press is automatically sent on the Tx communication line. If the display module is running in I²C mode, the key press will remain in the buffer until it is accessed using the display read address. Table 11: Keypad Pinout Figure 16: Keypad Header Pin 1 2 3 4 5 6 Function Gnd Row 1 Row 2 Row 3 Row 4 Row 5 Pin 7 8 9 10 11 12 Function Column 1 Column 2 Column 3 Column 4 Column 5 Gnd/Vcc** The character that is associated with each key press may be altered using the “Assign Key Codes” command. The straight twelve pin header of the Keypad Interface Connector will interface to a variety of different devices including the Matrix Orbital KPP4x4 keypad. *Note: If connecting a relay, be sure that it is fully clamped using a diode and capacitor in order to absorb any electro-motive force (EMF) which will be generated. **Note: The Ground / +5V pin is toggled by the jumper to the right of the keypad connector. Jump pads 1 & 2 for +5V or 2 & 3 for GND. GTT50A Hardware Manual 10 5 Troubleshooting 5.1 Power To function correctly, the GTT50A must be supplied with the appropriate power. If the power LED near the top right corner of the board is not illuminated, power is not applied correctly. Try the tips below.    GTT devices have specific power requirements. Ensure the correct voltage and sufficient current are available to your device by consulting the Power Consumption table. Check the power cable which you are using for continuity. If you don't have an ohm meter, try using a different power cable, if this does not help try a different power supply. Check the power connector in use on your display. If the connector has become loose or you are unable to resolve the issue, please use the Contact section to reach a friendly Matrix Orbital support representative. 5.2 Display If your display is powered successfully with an AUTOEXEC file present, the Matrix Orbital logo or user specified screen should display briefly on start up. If this is not the case, check out these tips.  If any start-up issues are encountered, it is recommended that you remove the AUTOEXEC file from the SD card to allow the unit to start with factory defaults. 5.3 Communication When communication of either text or commands is interrupted, try the steps below.       First, check the communication cable for continuity. If you don't have an ohm meter, try using a different communication cable. If you are using a PC try using a different Com Port. In USB protocol, ensure that a connection is made to the header labelled USB, not Mass Storage and check that the mode selection jumper is not placed on the “A” side. In serial protocol, ensure that the host system and display module are both communicating on the same baud rate. The default baud rate for the display module is 115,200 bps. Match Rx from the display to the transmit pin from your host and the Tx pin to receive. If you are communicating to the display via I²C* please ensure that the data is being sent to the correct address. The default slave address is decimal 80 (0x50 hex). In I2C mode, connect SDA to the data line of your controller and SCL to the clock output. 5.4 Factory Defaults If the settings of your display become altered in a way that dramatically impacts usability, the default settings can be restored simply by removing the AUTOEXEC file in the memory card’s root directory. This will remove the start screen and reset the baud rate to 115,200. If the Matrix Orbital start screen is desired, default files are available at www.matrixorbital.ca/manuals/GTT_Series/GTT_Example_Files. *Note: I²C communication will always require pull up resistors on SCL and SDA of one to ten kilohms. 11 GTT50A Hardware Manual 6 Appendix 6.1 Dimensional Drawing Figure 17: GTT50A Drawing GTT50A Hardware Manual 12 6.2 Power Consumption 6.3 Environmental Table 12: Required Supply Voltage Parameter Min Typ Max Unit Supply Voltage 4.75 5.0 5.25 V 9.0 12.0 35.0 V Table 14: Environmental Specifications Remarks Standard Voltage (V5) Wide Voltage (VPT) Table 13: Operating Current Draw Parameter Min Typ Max Unit Remarks Logic Backlight Piezo Motor GPO - 265 - mA Backlight Off 0 TBD 350 mA Off, Mid, Max - 80 - mA Burst - 110 - mA Burst - 15 mA Each 0°C to +50°C Operating Temperature -20°C to +70°C Storage Temperature 95% (T < 40°C) Operating Relative 85% (40°C < T < 50°C) Humidity* *Note: No condensation at any temperature 6.4 Touch Specifications Table 15: Touch Screen Attributes Hardness Required Force Active Area 6.5 Optical Characteristics 6.6 ESD Performance Table 16: Optical Characteristics Table 17: ESD Resistance Data Module Size 142.0 x 90.0 x 17.0 mm Viewing Area 111.80 x 68.80 mm 108.00 x 64.80 mm Active Area 800 x RGB x 480 Pixel Pattern 0.135 x 0.135 mm Dot Pitch 2 240 cd/m Luminance 65° Left, Right Viewing Angle Contrast Ratio 3.0 H 20 N 109.00 x 65.80 mm Component Value Unit ±15 kV Serial Translator ±15 (RS232, RS422) ±8 kV Controller 2 (I C, TTL) 50° Up, 60° Down 350:1 ±4 kV kV Remarks Human Body Model Air Gap (IEC 1000-4-2) Contact (IEC 1000-4-2) Human Body Model 6.7 Electrical Characteristics Absolute Maximum Ratings Table 18: GTT50A Limiting Values Parameter Supply Voltage RS232 Pins RS422 Pins I2C/TTL pins USB Pins 13 Min Max Unit Remarks -0.5 -0.5 -25 -13.2 -13 -0.5 -0.5 6 35 25 13.2 13 3.6 3.8 V V V V V V V Standard Voltage (V5) Option Extended Wide Voltage (VPT) Option Input Signals Output Signals Inverting and Non, Input and Output Signals SCL, SDA, Input and Output Signals Input and Output Signals GTT50A Hardware Manual Communication Characteristics Table 19: RS232 Interface Characteristics Min Parameter Input Threshold Low 0.6 Input Threshold High Output Voltage Swing ±5.0 Input Resistance 3 Output Resistance 300 Output Short Circuit Current - Typ Max Unit 1.2 V 1.5 2.4 V ±5.4 V 5 7 kΩ 10M Ω ±35 ±60 mA Table 20: USB Interface Characteristics Parameter Min Typ Max Unit Static Output High Static Output Low Input Differential Threshold 2.8 0.2 Common Mode Output Voltage 0.8 Driver Output Impedance 2 26 - 3.6 0.3 - - 2.5 V 29 44 Ω Table 21: I C Interface Characteristics Table 22: TTL Interface Characteristics Parameter Min Typ Max Unit Parameter Input Threshold Low Input Threshold High Output Voltage Low Output Short Circuit Current 0 1.0 V 2.3 3.3 3.6 V 0 0.4 V - ±50 mA Input Threshold Low Input Threshold High Output Voltage Low Output Voltage High Output Short Circuit Current V V V Min Typ Max nit 2.3 2.9 - 0 3.3 0 3 - 1.0 V 3.6 V 0.4 V 3.3 V ±50 mA Table 23: RS422 Interface Characteristics Parameter Min Typ Max Unit Input Voltage (A and B) -7.0 - 12.0 Input Differential Threshold -200 -125 -50 Differential Driver Output 2 3.3 Common Mode Output Voltage - 1.65 3 Input Resistance 96 Driver Short Circuit Current Limit - 250 Receiver Output Short Circuit Current 95 V mV V V kΩ mA mA Remarks -7V < Vin < +12V RL = 100Ω -7V < Vin < +12V 6.8 Defect Criteria Display Specifications Appearance Specifications Table 24: Display Defect Criteria Defect Line Bright Dots Dark Dots Total Condition Not Allowed Red + Green + Blue Within φ10mm Circle Red + Green + Blue Within φ10mm Circle Bright Dots + Dark Dots Table 25: Screen and Touch Defect Criteria Criteria N/A ≤ 3 Dots 0 Sets ≤ 3 Dots 0 Sets ≤ 3 Dots Defect* Condition d < 0.10mm Circular 0.10mm ≤ d < 0.20mm Objects (Stains, Dust, Scratch, 0.20mm ≤ d < 0.25mm Bubble, Dark/White spot, Foreign matter) 0.25mm ≤ d < 0.30mm W≤0.015mm W≤0.05mm, L≤2.0mm Linear Objects W≤0.03mm, L≤3.0mm W>0.1mm, L≥1.0mm *Note: Defects must occur in Active Area GTT50A Hardware Manual Critera Allowed ≤3points ≤2points ≤1points Allowed ≤2points ≤2points ≤1points 14 7 Definitions 9-Slice: Graphic format used to scale bitmaps, usually rectangular, without distorting their geometry.
