Electromagnetic Compatibility (EMC)
Compliance
The ‘IO-CON-1 / 2 / 3 Modules’ are CE Approved products. They are 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 ‘IO-CON Modules’ 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 antistatic 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.

3.0 ISP Header Selection
3.1 Overview
The method of connection to the Target System or Test Fixture is usually dictated by the interconnect
method already used on the Target System or Test Fixture. If the programmer is to be interfaced
directly to a header on a Target System, then it is likely that one of the 6-wy or 10-way ISP box
headers will be used. If, however, the programmer is to be interfaced to a Test Fixture, then ‘Wirewrap’ or ‘Fast Connect’ clip-in connects are more likely to be used.
The choice of possible headers and connection systems are detailed in section 3.1.
The available headers for a particular device manufacturer / device type are detailed in section 3.2.
3.2 ISP Header Selection Chart (by header)
The various ISP Headers featured on the EQ-IO-CON modules are detailed in the table below. Please

3.4 Atmel 6-way ISP Header (SPI Interface)
This connection method is suitable for interfacing the programmer to a Target System which features
the following:
• Atmel 6-way IDC ISP Header
• An Atmel device which features the 3-wire SPI + RESET Programming Interface
The 6-way IDC box header is the most compact header i.e. takes up least space on the Target
System and so is very popular for designs where PCB space is limited. Unfortunately, this connection
method does not have any pins spare for extra functionality such as the SCK2 Oscillator so it should
only be used if this functionality is not required.
To implement this connection method, simply plug a 6-way ISP cable (not supplied) into the 6-way
ISP header and plug the other end of the cable into the matching header on the Target System.

3.6 Equinox 10-way Header (ATtiny11/12/15 HV Interface)
This connection method is suitable for interfacing the programmer to a Target System which features
the following:
• Equinox 10-way IDC ISP Header
• An Atmel ATtiny microcontroller e.g. ATtiny11/12/15
• Suitable connections to implement ‘High Voltage Serial Programming Mode’.
The connector supports programming of the Atmel ATtiny11/12/15 microcontrollers in ‘High Voltage
Serial Programming Mode’. This mode requires that a +12.0V Vpp voltage is applied to the RESET
pin of the target device in order to enter programming mode.
To implement this connection, simply plug the 10-way ISP cable into the 10-way header marked
‘Equinox’ and plug the other end of the cable into the matching header on the Target System. Please
ensure that you have made the correct connections from the ISP Header to your Target Device.

4.0 ISP Cable considerations
The programmer is supplied with a single 10-way ISP Cable as standard. This cable is terminated
with a 10-way IDC 0.1” female polarised plug at each end. The cable is wired as a so-called ‘straightthrough’ cable with pin 1-1, 2-2 etc. The polarised ISP Header ensures that the ISP Cable cannot be
plugged in the wrong way around by mistake. If you are planning to design such a header onto your
Target System, it is strongly recommended that a similar polarised header is used. This will help to
prevent accidental damage to both the programmer and the Target System.
Pin 1 of the ISP cable can be determined by looking for a small arrow on the plastic part of the ISP
female plug. If the cable has a RED stripe on one cable, this usually also indicates pin 1.
If you are using the programmer in a production environment and constantly plugging / unplugging the
ISP cable into/from the Target System, you may find that the cable eventually fails. Spare ISP cables
can be ordered from Equinox in this eventuality.

8.5 Clip-In fast Connector (J3 & J4)
The ‘Fast-Connect’ connectors J3 and J4 allow direct wiring of a Test Fixture to the programmer by
simply clipping the bare end of the each Test Lead into the relevant pin of the connector. This method
of connection is for connecting to a Test Fixture as wires can easily be interchanged without having to
desolder connections or make new cables.

9.0 EQ-CALCON Module
9.1 Overview
The EQ-CALCON Module is a special plug-in I/O Connector Module for the PPM3-MK2 programmer
which is used to facilitate very accurate calibration of the Internal Oscillator of an Atmel ATmega or
ATtiny AVR microcontroller. The module features an on-board high accuracy 32kHz Oscillator
Module which can be connected to the target AVR microcontroller MOSI pin during the Oscillator
Calibration Procedure as described in the Atmel Application Note 'AVR053: Calibration of the Internal
Oscillator'.
The EQ-CALCON Module is simply an I/O Connection Module with an on-board 32kHz oscillator. The
target microcontroller SPI or JTAG signal lines connect to the module headers or clip-in connectors.
The 32kHz oscillator is then switched onto the target device MOSI pin under control of the
Programming Project running in the programmer. The EQ-CALCON Module must be used in
conjunction with a PPM3-MK2 programmer in order to operate.
