An overview of the available control mechanisms is given below. Standalone Operation(Keypad) This indicates that the programmer can be operated without being connected to a PC or other control system. In this case an operator can control programming operations using a keypad on the programmer e.g. Epsilon5, FS200A, PPM3-MK2 Remote System Control (4-wire) This indicates that the programmer can be controlled from a remote electrical system e.g. In Circuit Tester using a 4-wire TTL protocol (START, ACTIVE, PASS, FAIL). This method only supports execution of ‘Standalone Programming Projects’ which have been previously uploaded to the programmer. ASCII Text Mode Control This indicates that the programmer can be controlled using a simple 'ASCII Serial Communications Protocol'. This is ideal for applications where a Remote System wishes to control the programmer using a serial communications link e.g. RS-232. This method only supports execution of ‘Standalone Programming Projects’ which have been previously uploaded to the programmer. ISP-PRO Software This software suite is capable of controlling up to 16 x Equinox Production ISP programmers on an RS-485 network at the same time. All programming operations are controlled via 'Programming Scripts' and 'Programming Projects' which have been created using EQTools. The application minimises user intervention during programming and logs all programming operations to an Interface Database. Labview Control (PC) This allows an Equinox programmer to be controlled by a remote Labview Application. The Labview application can launch 'Programming Scripts' and read/write unique data such as serial numbers and calibration data. Remote Application Control (PC) This allows an Equinox programmer to be controlled by a Remote Application written in e.g. Visual Basic, C++ etc. The Remote Application can launch 'Programming Scripts' and read/write unique data such as serial numbers and calibration data. ConsoleEDS This is a powerful utility which allows any Equinox ISP Programmer to be controlled from a PC application by executing simple command-line instructions. This method of control is ideal for interfacing the programmer to any Windows application including Visual Basic, Labview etc. PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 23 2.3.3 Software Installation The PPM3 programmer comes with the software suite called EQTools as standard.

PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 41 2.7 ASCII Text Communications Mode 2.7.1 Overview The ‘ASCII Text Control’ communications protocol or ‘ATC’ is designed as a simple way for a Remote Test System to control the basic programming operations of an Equinox programmer via an RS-232 serial link. It is an ‘ASCII’ protocol with simple commands to initiate programming of pre-loaded ‘Programming Projects’ which are stored in the on-board ‘FLASH Memory Store’ of the programmer. The protocol supports up to 64 independent Programming Projects per programmer, but is limited to one programmer. Implementation of this protocol is straightforward due to the limited number of commands and restricted functionality. As this is an ASCII protocol, it can be quickly evaluated using any Terminal Emulation Software Utility such as Hyperterminal. 2.7.2 Programmers supported The Equinox programmers which are capable of supporting ‘ASCII Text Mode’ control are listed in the table below. Programmer ASCII Text Mode Control Order Code EPSILON5 License upgrade required EPSILON5A1-UPG6 FS2000A License upgrade required FS2000A-UPG7 PPM3 MK1 Enabled as standard N/A PPM3 MK2 Enabled as standard N/A Please note: 1. The PPM3 range of Production ISP Programmers are enabled for ‘ASCII Text Mode’ control as standard. The ‘Communications Node Address’ must be set to address ‘0’. 2. A license upgrade is required for all other programmers to enable them for ‘ASCII Text Mode’. 2.7.3 Limitations of this protocol This protocol has been designed as a simple method to allow a Remote Application such as an InCircuit Tester to control the basic operations of an Equinox programmer. The programmer only supports the programming of entire ‘Programming Projects’ which are already uploaded to the programmer on-board FLASH memory. This protocol does not support writing / reading of individual bytes or blocks of data to / from a Target Device. The limitations of this protocol are as follows: 1. The protocol only supports programming of Programming Projects which are pre-loaded into the Programmer on-board FLASH Memory Store. 2. The protocol does not support writing / reading of individual bytes or blocks of data to / from a Target Device. 3. The protocol does not support uploading of ‘Programming Projects’ to the programmer. This must be performed using the EQTools – Project Upload Wizard. 4. Only very limited diagnostics are available using this protocol ie. FAIL + Error Number. 2.7.4 Further Information A full description of this protocol can be found in the Application Note ‘AN110 - ASCII Text Control (ATC) Protocol for Remote Control of Equinox Programmers’. 42 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 2.8 Standalone Remote I/O Programmer Control 2.8.1 Overview The PPM3 programmer can be controlled using a simple 4-wire Remote I/O (TTL) signalling protocol as shown in the diagram below. This control method is ideal for interfacing the programmer to InCircuit Testers (ICT’s) or other production equipment which does not have an RS-232 port. Fig. 2.8.1 Remote System Control of Programmer START ACTIVE Remote System OK Equinox PPM3 Programming Module FAIL GROUND The Remote System simply asserts the programmer signal to initiate the execution of a ‘Programming Project’. The programmer will then assert the signal to indicate that it has commenced programming. At the end of the Programming operation the programmer asserts either the or signal depending on the outcome. The Remote System must then de-assert the signal to allow the programmer to reset ready to program the next device. Please refer to section 2.8.3 for an example of the Remote I/O control signal waveforms for a typical programming iteration. PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 43 2.8.2 TTL 4-Wire Control – Signal Connections The Remote System connects to the programmer via the ‘Remote System Control Port’ which is located on the relevant I/O Connection Module as shown in the table below. The signal names and descriptions are detailed in fig. 2.2.2b. Fig. 2.8.2a Remote System Control Port – signal connections I/O Connection Modules 1 and 3 I/O Connection Module 2 The ‘Remote System Control Port’ is the 6-way ‘Fast Connect’ connector marked as (5) on the above diagram. Unfortunately, the ‘ACTIVE’ signal is missing from this connector so this must be manually soldered to one of the red connectors. The ‘Remote System Control Port’ is located on the wire-wrap port marked as (4) on the above diagram.

PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 45 2.8.4 Setting up a Programming Project for TTL Control Mode When using ‘TTL Control Mode’, a single ‘Standalone Programming Project’ or set of ‘Chained Projects’ must have already been uploaded to the programmer. This project must be have the ‘Project Type’ set to ‘Standalone – Remote I/O Control’. Please note: It is not possible to control multiple Programming Projects using TTL mode as there is no method by which to select the project to be executed. TTL mode is therefore limited to single project. To create a TTL Mode control project: • Select • On the screen, select: o Programmer: PPM3-MK2 o Project type: Standalone – Remote I/O Control • • • 46 Set up the FLASH / EEPROM / Fuses / Security Fuses as normal Compile the project Upload to the programmer using the Upload Wizard PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 2.9 Target System Connect / Disconnect detection The PPM3-MK2 programmer has a special mode where it can detect when a Target System (UUT) is connected to or disconnected from the programmer. A load sensing technique is used to detect the presence of the UUT. This method of UUT detection can be used to trigger a ‘Standalone Programming Project’ or even a sequence of chained projects to start. The typical sequence of events is as follows: • Programmer waits for UUT to be connected (flashing BUSY LED) • Operator connects UUT to programmer • Programmer detects connection of UUT • Programmer automatically executes a sequence of Standalone Programming Projects • At the end of the programming sequence, the programmer will FLASH either the PASS or FAIL LED • Programmer then goes into ‘Target Disconnection Sensing’ mode (flashing BUSY LED) • Operator removes the UUT • Programmer resets itself ready for the next UUT Please contact Equinox for further instructions on how to set up your programmer to operate in this mode. 2.10 Script Mode (ISP-PRO) ‘Script Mode’ is designed for production users who require logging of all programmer operations to a database. This mode utilises the Equinox ISP-PRO software which allows execution of Programming Scripts. It is possible to write scripts to program unique data such as serial numbers, calibration data etc. It is also possible to control the programmer from a Remote Application written in eg. Labview, Visual Basic, C++ etc. In order to use ‘Script Mode’ with your programmer, it is necessary to purchase the relevant license upgrade for ISP-PRO. Please see the Equinox Website for further details. PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 47 2.11 ConsoleEDS – Command Line control ConsoleEDS is a powerful software utility which allows any Equinox ISP Programmer to be controlled from a custom Remote Application running under Windows. The main features of ConsoleEDS are: • Allows an Equinox ISP Programmer to be remote controlled via simple Command Line commands. • Suitable for interfacing to any application which executes under Windows • Simple Command Line interface makes even complex programming operations simple to implement • Supports writing of a block of data from a file to the FLASH or EEPROM of a Target Chip • Supports reading of a block of data from the FLASH or EEPROM of the Target Chip to a file on the PC hard disk • Supports uploading of pre-compiled standalone ‘Programming Projects’ to a target programmer without requiring EQTools or the Project Upload Wizard. • Supports running of a specified ‘Programming Project’ which has already been uploaded into the programmer ‘FLASH Memory Store’ • Supports programming of the ‘Configuration Fuses’ of the Target Chip • Supports programming of the ‘Security Fuses’ of the Target Chip • Supports automatic generation of and programming of unique information such as serial numbers and calibration data • Supports reading / writing of Atmel AVR on-chip Oscillator Calibration Byte Please note: Many of the above features are only accessible when using ‘ConsoleEDS PRO’.

The Module features an RS-232 port which can connect to a COM port of any suitable Control System such as a PC running the Equinox EQTools software. This mode of operation is restricted to a single programmer channel. In many medium to high volume production applications there is a requirement to run more than one PPM3 programmer from the same PC COM port. This can be achieved by daisy-chaining up to 16 modules (using the RS-485 In/Out ports on each programmer) on an RS-485 bus and using an RS485 converter to convert the PC RS-232 COM port to the required RS-485 levels. The Equinox ISPPRO Software Suite is required to run the programmers in this mode. The table below details the applications of both the RS-232 and RS-485 communications modes.

For RS-232 operation (default setting): • Set the RS-232 / RS-485 DIP Switch (5) to the ON (RS-232) position • Set the Node Address to ‘0’ (default address). • Connect the 9-way serial cable from the 9-way COM port on the PPM3 programmer to a spare COM port on your PC or other RS-232 Control System 52 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 3.5 RS-485 Operation It is possible to network up to 16 x PPM3 programmers on an RS-485 network and control them from a single ‘Supervisor PC’ running a single session of the Equinox EQTools or ISP-PRO software. This scenario requires that each PPM3 programmer is set to ‘RS-485’ operation and that a unique ‘Node Address’ is set for each programmer. An RS-232 to RS-485 converter is also required to convert the RS-232 signal from the PC COM port to an optically isolated RS-485 signal suitable for interfacing with the PPM3’s on the network. The typical setup is shown in the figure below. Fig. 3.5 Setup for RS-485 Communications (Multi channel) For RS-485 operation: • Place the PPM3 programmers side-by-side on a flat surface with the rear panels all facing in the same direction as detailed in fig. 3.5 • For each PPM3 programmer, set the RS-232 / RS-485 DIP Switch (5) to the RS-485 position • For each PPM3 programmer set the required Node Address in the range 0 – 15. (Each programmer must have unique address. It is customary to start have the first programmer set to address 0, the next programmer in the chain at address 1 and so on. See section 3.3 for further details.) • Plug the 9-way RS-232 cable into the port on the RS-232 to RS-485 converter and connect the other end of the cable to a spare PC COM port. • Plug an RS-485 network cable from one of the RS-485 outputs on the RS-485 converter to the ‘RS-485 Input’ connector (left-hand connector) on the rear panel of the first PPM3 Module. • Plug another RS-485 network cable from the ‘RS-485 Output’ connector (right-hand connector) on the rear panel of the first PPM3 to the next PPM3 in the chain. • A return RS-485 cable from the last PPM3 in the chain to the RS-485 converter is NOT required. • Power up the PC. • Plug in and switch on the power supply adaptor supplied with the RS-232/RS-485 convertor into a spare mains socket. • Power up all PPM3 Programmers. • Launch the ISP-PRO software on the PC and set up the required number of PPM’s within the software. • Test that all PPM3’s are communicating with the PC at their correct ‘Node Address’. (The Node Address may be changed while the programmer is powered up). PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 53 3.6 Serial Cables and adaptors The programmer is supplied with the following PC Serial Cables / Adaptors: 1. 9-way D (female) to 9-way D (Male) Serial Cable This cable should be connected between the 9-way D connector on the programmer and a spare 9way RS-232 COM port on your PC. 2. 9-way D (female) to 25-way D (Female) adaptor If your PC has a 25-way D connector, you will need to plug the 9-25way adaptor onto the end of the 9-9 way Serial Cable as shown in the diagram below. 3.7 RS-232 Serial Cable Specification The serial cable supplied with the programmer is approximately 2m in length. If you wish to make your own longer cable, please ensure that you connect all 9 pins at each end in a straight-through pin-topin fashion. See fig. 3.7 for the pin-out specifications. The programmer features an ESD protected full RS-232 specification driver chipset and so should operate reliably when driving serial cables up to 10m in length. However, it is recommended to keep the serial cable as short as possible to enhance EMI immunity and reduce EMI emissions. Important note: The programmer uses ALL of the NINE pins of the COM port for different purposes. It is therefore imperative that the cable used to connect between the programmer and the PC COM port has all NINE cables connected. Failure to do this will result in the programmer not operating correctly. 54 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 3.8 RS-232 Serial Cable Pin-outs Fig. 3.8.1 Pin-out RS-232 Communications Port Pin No. RS232 pin Description 1 DCD Controls the RESET pin of the programmer ATmega128 controller during the Firmware Update process.

Please refer to the table below to choose the required ‘Power Supply Scenario’: Fig. 4.1 Power supply scenarios # Power Supply Scenario Refer to section 1 Programmer supplies Controlled Voltage to the Target System (@ user specified voltage and maximum current) 4.7 2 Target System powers the Programmer (@ 5.0V only) 4.8 3 Programmer and Target System are independently powered 4.9 Please note: The favoured method of powering is for the programmer to power the Target System as using this method means that the sequencing of power is controlled from the Programming Project / Script. This allows the PPM3 Programmer to be a completely self-contained Programming System with no requirement for an external Target Power supply and the associated power sequencing system. This section also details the actual power connectors, voltage range and earthing requirements of the programmer. Please see the table below for the relevant section reference.

Please see section 4.3. 56 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 4.2 Power Connectors (rear panel) The PPM3 rear panel power connectors are shown in the figure below. The Jack Socket and 2-way Molex connectors are wired in parallel internally. The input voltage for both connectors is 9.0 to 12.0V DC regulated from an external power supply. Fig. 3.2.1 PPM3 Module – Rear Panel Connectors Key No Function Further description 1 DC Power Input (1) • • 2.5mm Jack socket (centre positive) Input voltage: 9.0 – 12.0V DC regulated 2 DC Power Input (2) • • • 2-way Molex connector Input voltage: 9.0 – 12.0V DC regulated This connector is wired internally in parallel with the jack socket input (1). 4.3 DC Power Cable Specification The programmer is supplied with a DC power cable which plugs into the DC power connector jack socket on the rear panel of the programmer. The other end of this cable is supplied with bare wire ends for connecting to an external power supply. e.g. bench PSU. Cable Specification: • One end features a female 2.5mm DC jack plug • The other end of the cable is supplied with bare wire ends for connecting to an external power supply. e.g. bench PSU. • The black lead with the white stripe is the +VE cable. • The all black lead is the GROUND cable. • The external voltage applied to the Jack Socket connector must be between 9.0 and 12.0V DC regulated ! PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 57 4.4 Voltage range 4.4.1 Programmer Output / Supply Voltage range The PPM3 Module has been designed so that it can be powered from an external 9.0 to 12.0V DC regulated power supply via the jack socket (J6) or directly from a Target System running at +5.0V DC. The programmer is capable of generating a controlled supply voltage to the Target System of between 3.0V and 5.0V at 300mA, but this is only possible if the programmer is powered from an external 9.0 to 12.0V power supply, Fig. 1.5.2 Programmer voltage supply range for reliable operation # Programmer mode Min Vcc Max Vcc Units 1 3.00 Programmer powering the Target System • Programmer must be powered by external 9V DC supply via DC power connector (J6) or Molex power connector (J16) • Programmer is capable of generating a controlled supply voltage to the Target System of between 3.0V and 5.0V at 300mA • Target Sense functionality is only available in this mode. 5.00 V 2 Target System powering the programmer 5.00 • Programmer circuitry must be powered at +5V • Target System must supply +5.0V via one of the ISP Headers to the programmer. 5.00 V 58 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 4.4.2 Device Programming Voltage Range The PPM3 programmer can program devices with a target voltage between the min. and max. values detailed in the table below. The programmer cannot currently support programming of devices below 3.V. Please contact Equinox directly for further assistance if your Target Voltage is < 3.0V. # Programmer mode Min Vcc Max Vcc Units 1 Allowed voltage range for actual programming of devices 3.00 5.00 V Important note: To verify that a particular device can be programmed at a certain Vcc voltage: • Check the supply / programming voltage parameters for the actual device (IC) in the manufacturer’s datasheet. • Many devices have two different voltage range versions eg. 2.7 – 6.0V and 4.0 – 6.0V. Please ensure that you are programming the device within the stated voltage range. • Ensure that you have selected the required Target Vcc Voltage in your EQTools – Programming Project (*.ppm). e.g. if you are programming at +3.3V, you must set up this voltage in your Programming Project. This can be found in the EQTools - Project Builder tab. • For most Atmel AVR and AT89S devices, the FLASH and EEPROM Write Times increase as the Target Voltage decreases. The timings are automatically set for you in your project as long as you have declared the correct Target Vcc voltage in your project. PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 59 4.5 Programmer / Target System Power Supply Schematic The schematic shown in fig. 4.5 details the possible power supply scenarios for powering both the programmer and the Target System. The key points to note are as follows: • The programmer can be powered from an external power supply (9.0 – 12.0V DC regulated) via either the ‘DC Jack Socket (J6)’ or the ‘DC Molex Connector (J15)’ • The programmer can power the Target System with a user-specified voltage from 3.0 – 5.0V via the ‘Programmer Controlled Power Supply’. • The programmer ‘Line Driver Circuitry’ must always be powered at the same voltage as the Target System. This ensures that the logic levels generated from the programmer are compatible with the logic levels on the Target System. • The external link ‘LK1’ is a virtual link. It simply represents that the Vcc connection between the programmer and Target Vcc is broken. fig. 3.2.1. Explanation of all Power Supply Circuit Schematic labels # Item Description 1 V_PSU_EXT • This is the voltage applied from an external power supply (9.0 – 12.0V DC regulated) via either the ‘DC Jack Socket (J6)’ or the ‘DC Molex Connector (J15)’ 2 GND • This is the common ground of the programmer which is connected to J6/J15 GROUND and also to the TARGET GROUND via one of the ISP Headers. 3 V_Target • This is the voltage measured between the Vcc and Ground of the Target System. 4 LK1 • This is a virtual link (does not really exist) signifying the cable between the Programmer TVCC and the Target System Vcc. If the programmer and Target System are independently powered, then LK1 must be not fitted i.e. the Target System Vcc wire should not be connected to the programmer TVCC connection. • 4 I/O Level Converter / Driver Circuit • • This is the circuitry which translates the 5.0V I/O signals from the programmer ‘Supervisor Microcontroller’ to the Target System voltage levels. The supply to the ‘I/O Level Converters’ must be at the same voltage as the Target System. I.e. if the Target System is powered at 3.3V, then the ‘I/O Level Converters’ must also be powered at 3.3V. 5 Target Load • This is the load presented to the programmer across the PROG_VCC and GROUND terminals of any ISP Header. 6 Bench Power Supply • This simply indicates a stable DC power supply with a current limit facility. 60 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 Fig 4.5 – Programmer / Target System Power Supply Overview Schematic PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 61 4.6 Earthing requirements 4.6.1 Overview When setting up the programmer to In-System Program (ISP) a device on a Target System, extreme care must be taken to ensure that the 0V of the PC, programmer, Target System and any external devices are at the same ‘earth potential’. If you are using the programmer with a laptop computer, please read section 3.2.2 carefully. ESD Points to remember Failure to follow correct ESD procedures when using this product could lead to damage to the programmer and/or the Target System. • Wear an earthed wrist strap when handling either the programmer and/or any programmable device. • Ensure that the PC, programmer, Target System and any external devices are all connected to the same GROUND potential. 4.6.2 Laptop earthing issues The Problem: Most laptops use an external double-insulated mains power supply which is not earthed to mains earth. This means that the laptop earth is likely to be floating at some voltage other than 0V. If the programmer is attached to the PC COM port with the PC powered ON and then the ISP lead is plugged into an earthed Target System, then the PC GROUND will discharge through the COM port GROUND, through the programmer into the Target System. This ESD may damage both the programmer and the Target System ! The Solution • Ensure that the laptop is powered OFF when connecting the ISP cable from the programmer to an earthed Target system • Use the programmer in Standalone Mode if possible (ie. not connected to a PC) 4.6.3 Desktop PC earthing issues The Problem: The chassis on desktop PC must be connected to mains earth to comply with Health and Safety legislation. If the chassis is not earthed for some reason, the PC power supply GROUND will be floating and it is then possible to discharge a high level of energy stored in the power supply mains filter through the programmer into the Target System. This ESD may damage both the programmer and the Target System ! The solution: • Ensure that the PC chassis is properly earthed to mains earth. • Connect an earthing bond wire from the PC chassis to the GROUND connection of either the programmer or the Target system / Test Fixture. 62 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 4.6.4 Earthing recommendations To avoid catastrophic damage to PC, programmer or target system: • Ensure that both your target system and PC are connected to a common earth point • Make sure that all interconnections are made before applying power to PC and target system • • • If you are using a laptop or PC which is not connected to mains earth, it is recommended that you make a hard-wired connection from the COM port D-connector shell and the target system to a common earth point Avoid plugging and unplugging ISP connector while either the PC or Target System is powered up Please ensure that any devices connected to the user target system are also properly grounded to the same common earth point Warning! Any damage caused to the programmer by Electrostatic Discharge (ESD) through inadequate earthing is not covered under the warranty of the product. PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 63 4.7 Programmer Powers the Target System 4.7.1 Overview The PPM3 programmer is capable of supplying a controlled voltage from 3.0 to 5.0V to power the Target System at a maximum current of 300mA. This allows the programmer to power the Target System via the ISP Cable and switch power on / off under Programming Project / Script control. The voltage and current settings must be set up in the Programming Project prior to powering up the Target System. In this mode it is also possible for the programmer to automatically sense whether a Target System is connected to the programmer – see Target Sensing section. Fig. 4.7.1 Programmer powering the Target System fig. 4.7.2 Settings for the programmer powering the Target System # Parameter 1 Programmer Input voltage source • • External 9.0 – 12.0 V DC regulated supply required Connect power supply to either DC Jack Socket or 2-way Molex Power Connector on the rear panel of the programmer. 2 V_Target (Output voltage to Target System) • • Programmer outputs a Controlled Voltage to the Target System: 3.0 – 5.0V DC @ 300mA max Voltage / current setting must be set up in the Programming Project 3 Vcc Option Link • Not Fitted 4 LK1 Link • • Fitted Programmer Vcc signal should be connected to the Target Vcc 5 Programmer I/O Level Converters • Programmer I/O Level Converter is powered at the Controlled Voltage which is the same as the Target System voltage. 64 Description PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 4.7.2 Instructions The instructions below detail how to set up the programmer to supply a controlled voltage to the Target System. 1. Create a Programming Project which powers the Target System • In EQTools – Project Builder – Select the tab • Set the required ‘Target Voltage’ and ‘Tolerance’ eg. 3.3V +/- 500mV. • The Voltage ‘Stabilise Time’ should be set to a long enough time to allow the voltage to reach its final voltage (default: 200ms). • Under the ‘Programmer Controlled Power Supply’ section, select: Æ This enables the programmer to supply power to the Target System. • Enter the maximum current which your Target System could take from the programmer supply (worst case i.e. current inrush condition) • Leave all other settings as the default values PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 65 2.

The Target Voltage must be +5.0V for the programmer to operate correctly. This mode is not recommended for general use as the programmer is powered on/off every time the Target System is powered on/off. This can lead to over-voltage and ESD problems. It also makes the programming times longer as the programmer must run its internal self-check algorithm every time it is powered up. Fig. 4.8.1 Target System powers the programmer at 5.0V Please note • The external voltage applied to the programmer must be between 5.0V! • The Programming Project must specify a Target Voltage of +5.0V. • The Target System must be able to supply the worst case current required during a programming operation. • A 6V2 5W zener diode is internally connected across the programmer supply to protect against over-voltage. 68 PPM3 MKII Programmer - User Guide - V1.04 - 10th May 2008 fig. 4.8.2 Settings for Target System powering the programmer # Parameter Description 1 Programmer Input voltage source • None 2 V_Target (Output voltage to Target System) • • • None The Target System must supply +5.0V to the programmer.

The programmer must be powered via one of the ‘DC Power Connectors’ on the rear panel at 9.0 – 12.0V. The Target System is powered from an external power supply in the range of 3.0 to 5.0V. The Programmer_Vcc output must NOT be connected to the Target_Vcc line in this scenario. Fig. 4.9.1 Programmer and Target System are independently powered Explanation of operation: • The programmer is always powered ON • The ‘Vcc Option Link’ is removed • LK1 connection is removed (ie. Programmer and Target Vcc are disconnected) • The programmer must supply the same voltage as the Target_Vcc to the Programmer ‘I/O Level Converter Circuitry’. • The Target Power Supply should be switched OFF before the ISP cable is plugged into it • The programmer does not draw any current from the Target System during programming • When programming is complete, the Target System should be powered OFF and then the ISP cable removed Warning! • The voltage applied to the programmer via the ISP cable must be between 3.0 and 5.0V as this voltage is used to drive the programmer I/O Stage. A 6V2 5W zener diode is internally connected across the programmer supply to protect against over-voltage. • The Programmer and Target Vcc must be physically disconnected by cutting the Vcc signal in the ISP cable if necessary.
