Introduction
The AIM104-IO32 is an 8-bit PC/104 module providing 32 channels of digital I/O. Each
channel can be configured as an input or an output. You can also choose to define the
power-up/reset state of the channels to be used as outputs. The I/O connector conforms
to Eurotech’s standard Signal Conditioning System (SCS), and can drive a range of
Signal Conditioning Boards (SCB). See Eurotech’s Eurocard catalogue for more details.
Features
32 channel digital I/O.
Each channel has a current sink capability of 24mA at 0.45V and source current of
500A at 2.7V .
Bit programmable for input or output.
Module access LED (on all decoded addresses).
8-bit PC/104 (IEEE996) bus interface.
I/O connector configured for Eurotech Signal Conditioning System.
Operating temperature range: -20°C to +70°C.
Power consumption from the host: max 250mA at +5V .
MTBF: 820,000 hours (using generic figures from MIL-HDBK-217F at ground
benign).
Handling your board safely
Anti-static handling
This board contains CMOS devices. These could be damaged in the event of static
electricity being discharged through them. Observe anti-static precautions at all times
when handling circuit boards. This includes storing boards in appropriate anti-static
packaging and wearing a wrist strap when handling them.
Electromagnetic compatibility (EMC)
The AIM104-IO32 is classified as a ‘component’ with regard to the European Community
EMC regulations and it is the user’s responsibility to ensure that systems using the board
are compliant with the appropriate EMC standards.
The opto-isolation provides a good barrier for noise emissions generated by the high
frequency host PC/104 system. The AIM104-IO32 includes additional filter components
on-board to minim
ise the emissions of high frequency noise. Because of this, the earth
tab supplied with the module must be connected to the chassis of the system by a good
earth wire.
Introduction
Issue G
5
If the electronic system requires input protection against high voltage transients (to meet
CE requirements), it is recommended that an external interface board is located at the
point where the external wiring enters the electronic system enclosure:
Packaging
Should a board need to be returned to Eurotech, please ensure that it is adequately
packed, preferably in the original packing material.
RoHS compliance
The European RoHS Directive (Restriction on the Use of Certain Hazardous Substances
– Directive 2002/95/EC) limits the amount of six specific substances within the
composition of the product. The AIM104-IO32 is available as an RoHS-6 compliant option
and is identified by an -R6 suffix in the product order code. A full RoHS Compliance
Materials Declaration Form is included in Appendix A – RoHS-6 Compliance - Materials
Declaration Form
, page 13. Further information about RoHS compliance is available on
the Eurotech web site: www.eurotech.com

Operation
When a channel is set low (0), the output is active and is sinking current. All outputs are
enabled by writing 01h to the Output Enable Control Register. This is illustrated below:
Each channel has an output that is an open collector drive, so each channel can, if
required, be configured as an input. To do this, follow these steps:
1 Switch the output OFF by writing a 0 to the output.
2 Either:
Drive the I/O signal high.
-or-
Pull the I/O signal low from an external signal.
3 Power-up or carry out a system reset to disable the outputs.
4 Use the power-on links to set the start-up output state for groups of eight channels.
If you are configuring a channel as an input, you must set the power-up link for
the appropriate group of eight channels in the A position. This means that any
channels to be used as outputs are set high or OFF.
A
good rule is to keep the channels to be used as inputs and those to be used as
outputs in separate groups of eight channels. You must write to the output control
latches, before the latch outputs are enabled. The read back registers connect
directly to the I/O signals and therefore reflect the true state of the I/O point. If an
I/O signal is low, it is read back as a 0.

Links
Use LK5 to set the base address of the module. The board access LED gives a
momentary flash when the board is successfully accessed. The board decodes eight
bytes from the base address.
The following diagrams illustrate the link positions:
