Electromagnetic Compatibility (EMC)

Compliance

The ‘PPM3 MK2 Programmer’ is a CE Approved Product. It is designed for use in an ESD controlled

environment i.e. development or production. This means, therefore, that the user must ensure that

there is no possibility of damage from electrostatic discharge (ESD). Since the devices and equipment

to which this product is likely to be connected may well themselves be susceptible to ESD, this should

not pose any difficulty.

For example, if you are handling microcontrollers and EEPROMS etc. then you will already be used to

appropriate precautions, such as the use of anti-static mats, wrist straps and so on. You should treat

your ‘PPM3 MK2 Programmer’ with the same care as you would these types of devices. Always

ensure that you are not yourself carrying a static charge before handling the product. Wearing an

earthed anti-static wrist strap is recommended.

Equinox have taken great care in designing this product to be compliant with the European EMC

directive. When using the equipment be sure to follow the instructions provided. Although RF

emissions are within prescribed limits, care should be taken if you are using the product near to

sensitive apparatus. If you experience any difficulty please refer to Equinox Technical Support.

ESD Points to remember

•

Work in a static-free environment.

Wear an earthed wrist strap when handling either the programmer and/or

any programmable device.

•

Ensure that the PC, programmer and Target system are connected to the

same EARTH (0V) potential.

Do NOT plug the ISP cable of the programmer into a Target System when

the Target power is ON.

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 - 10^thMay 2008

1.4 Special Function Modules (SFM)

1.4.1 SFM Module - Overview

The PPM3-MK2 programmer features an interchangeable ‘Special Function Module’. This module

contains all the ‘I/O Driver Circuitry’ which interfaces the programmer to the Target System. In the

event of damage to the programmer driver circuitry, it is possible to remove the complete Special

Function Module and replace it with a new one. This allows the programmer to be repaired in-situ

without the need to send it back to Equinox thereby saving valuable lost production time.

•

The PPM3-MK2 is fitted with the ‘EQ-SFM-1’ module as standard.

There are also other SFM modules available which offer faster SPI / JTAG speeds and better

ESD / Over-voltage protection.

1.4.2 SFM Module – Selection Guide

1.4.3 SFM Module – how to fit a new module

To fit a new SFM Module to the programmer:

•

Make sure the programmer is powered off

Remove all cables from the programmer

Remove the four fixing screws in the side of the programmer case

Carefully slide the lid of the programmer upwards and then off

You can find the existing SFM Module underneath the keypad PCB

Carefully remove the existing SFM Module by applying pressure from underneath at both

sides of the circuit board Æ the SFM module should pop out of the red connectors

Fit the new SFM Module in the same position and orientation as the one you have just take

out (make sure to line up the long red connector on the main PCB to the long red connector on

the SFM module

•

Push the new SFM Module down gently until it locks into place

Replace the programmer lid

Replace the programmer screws

1.4.4 SFM Module – declaring the module in a Programming Project

The EQ-SFM-1 and EQ-SFM-V1.2 / V1.3 modules actually use slightly different firmware in the

programmer. It is therefore necessary to specify which SFM Module is fitted in each Programming

Project.

To specify the correct SFM Module in a Programming Project:

In EDS (Development Mode):

•

Open your EDS (*.eds) development project

Select the <Programmer and device> tab

Locate the ‘Special Function Module fitted’ list box

Select the relevant SFM Module which you have fitted to your programmer

In Project Builder:

•

Open your Programming Project (*.ppm) project

Select the <Programmer and Project Type> tab

Locate the ‘Special Function Module fitted’ list box

Select the relevant SFM Module which you have fitted to your programmer

Re-compile your project to save the changes

Important notes:

•

Failure to specify the correct SFM Module can result in erratic operation of the programmer.

If you have existing projects which use the standard EQ-SFM module, these projects will need

to be recompiled for the new EQ-SFM-MAX 1.2 or 1.3 Modules.

2.3 Software Overview and Installation

2.3.1 Software Overview

The PPM3 programmer is supplied with a comprehensive Integrated Development Environment (IDE)

called ‘EQTools Version 2.xx Software Suite’. This software supports creation and testing of so-

called Programming Projects which can then be uploaded to the programmer for use in ‘Standalone

Mode’. EQTools contains many separate utilities most of which are enabled as standard for this

programmer. Certain options such as compiling and running of ‘Programming Scripts’ must be

purchased from Equinox as a ‘License upgrade.

The table below details the various EQTools components and whether they are enabled as standard.

2.3.2 Programmer Control Mechanisms

The programmer can be controlled from by many different methods including EQTools, EDS, from a

Remote System via the Equinox ISP-PRO software or via the ConsoleEDS command-line software.

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.

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.

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 In-

Circuit 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’.

PPM3 MKII Programmer - User Guide - V1.04 - 10^thMay 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 In-

Circuit 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

Equinox

Remote

System

PPM3

Programming

GROUND

The Remote System simply asserts the programmer <START> signal to initiate the execution of a

‘Programming Project’. The programmer will then assert the <ACTIVE> signal to indicate that it has

commenced programming. At the end of the Programming operation the programmer asserts either

the <OK> or <FAIL> signal depending on the outcome. The Remote System must then de-assert the

<Start> 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 - 10^thMay 2008

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

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 <Project Builder> <Create new project>

On the <Programmer and Project type> screen, select:

o

Programmer: PPM3-MK2

Project type: Standalone – Remote I/O Control

•

Set up the FLASH / EEPROM / Fuses / Security Fuses as normal

Compile the project

Upload to the programmer using the Upload Wizard

46

PPM3 MKII Programmer - User Guide - V1.04 - 10^thMay 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.

3.0 Serial Communications Ports

3.1 Overview

The PPM3 Programming Module can be controlled from any external device which supports either the

RS-232 or RS-485 hardware communications protocols. 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 RS-

485 converter to convert the PC RS-232 COM port to the required RS-485 levels. The Equinox ISP-

PRO 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.

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 - 10^thMay 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 9-

way 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-to-

pin 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.

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 <Target Vcc> 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.

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.

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 - 10^thMay 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.

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.

4.8 Target System powers the Programmer (5.0V only)

4.8.1 Overview

In this scenario, the programmer is powered from the Target System via the ISP cable. 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.

4.9 Programmer and Target System are independently powered

4.9.1 Overview

In this scenario, the programmer is powered from a completely independent supply to the Target

System. 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.

This ensures that the programmer I/O drivers are interfacing to the

same voltage levels as on the Target System.

4.9.2 Instructions

The instructions below detail how to set up the programmer when the Target System is independently

powered from the Target System.

Example:

•

The Target System is powered at 3.3V from an ‘Independent Power Supply’.

The programmer ‘Line Driver Circuitry’ must also be powered at 3.3V using the ‘Programmer

controlled Target Power Supply’

•

The Programmer TVCC and Target System Vcc are not physically connected

Here is how to set up the programmer:

1. Create a Programming Project which powers the programmer ‘I/O Level Converters’

•

In EQTools – Project Builder – Select the <Target Power Supply> 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).

•

Set the ‘Programmer controlled Power Supply’ to ‘ON’

Æ This enables the programmer to supply power to the programmer ‘I/O Level

Converters’ only.

•

The Target System is NOT powered by this voltage as the Programmer_Vcc and

Target Vcc are physically disconnected.

Leave all other settings as the default values.

2. Connect the Target System to the programmer

•

Connect the Target System to the programmer via an ISP Cable, Fast Connect connectors

or wire-wrap connectors.

•

Make sure that the Programmer_Vcc is NOT connected to the Target_Vcc. This may

involve physically cutting the Vcc signal in the ISP cable if you are using one of the ISP

headers to connect to the Target System. This is shown as a virtual link called ‘LK1’ on

the programmer schematic – see section 4.4.

•

Remove the ‘Vcc Option Link’ on the I/O Connector Module (labelled J6 or J28).

Using a DVM, check that there are no shorts between the Target_Vcc and Target

Ground

3. Test the Project in Equinox Development Suite (Target System connected)

•

Launch the Project in Equinox Development Suite

With your Target System CONNECTED, place a Volt Meter across the Target Vcc and

GROUND terminals of the programmer (on the I/O Connector Module)

Click the <Power Up> button in EDS

•

Æ the programmer <BUSY> LED should now illuminate

•

Measure the voltage across the Target_Vcc and GROUND terminals of the programmer.

Power up the Target System

Measure the voltage across the Target_Vcc and GROUND on the actual Target System

Compare the voltage measured across the programmer output and the Target_Vcc. These

voltages should be approximately the same.

•

Try a programming operation such as <Check Signature>
