J537 AIM104-IO32 2192-09783-000-000 AIM104- IO32 Assembly Kit Each AIM104 module is supplied with a mounting kit to secure the module. Handling All AIM104�s contain CMOS devices which could be damaged in the event of static electricity being discharged through them. At all times please observe anti-static precautions when handling the board and always unpack and install the board in an anti-static working area. Software A Utility Disk is supplied with your AIM104. It contains a host of software utilities designed specifically for each AIM104. Please refer to the README.TXT file on the disk for further information. It also includes a test program EXAMP-01.EXE which may be used to confirm access to the board. A summary of the software drivers can be found in the AIM104-Software Library. Introduction The AIM104-IO32 is an 8-bit PC/104 module providing 32 channels of digital I/O. Each channel may be configured as an input or an output. The module also has the facility to define the power-up/reset state of those channels to be used as outputs. The I/O connector conforms to Arcom�s standard Signal Conditioning System (SCS) and may be used to drive a range of Signal Conditioning Boards (SCB), see Arcom�s Eurocard catalogue for more details. Features � 32-channel digital I/O � Each channel has a current sink capability of 24mA @ 0.45V and source current of 500μA @ 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 Arcom Signal Conditioning System � Operating temperature range, -20�C to +70�C � Power consumption from the host, max 250mA @ +5V � MTBF: 820,000 hours (using generic figures from MIL-HDBK-217F at ground benign) CONTROL SYSTEMS Page 1 2192-09783-000-000 J537 AIM104-IO32 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. Since each channel has an output which is an open collector drive, each channel may alternatively be configured as an input by switching the output OFF (by writing a �0� to the output) and then driving the I/O signal either high or pulling it low from an external signal. On power up or on system reset, the outputs are disabled. The power-on links can then be used to set the start up output state for groups of eight channels. Power-Up state A B +5V 10K 4K7 I/O Signal Data D Q Enable Write Control Enable Outputs Read Status Note: If a channel is to be configured as an input, it is necessary that the power-up link for that group of 8 channels is set in the �A� position. This means that any channels to be used as outputs will be 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 8 channels. It is necessary to 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�.

The board access LED provides a momentary flash when the board is successfully accessed. The board decodes 8 bytes from the base address.

The AIM104-IO32 includes additional filter components on board to minimise the emissions of high frequency noise. The filter requires that the earth tab supplied with the module is connected by a good earth wire to the chassis of the system. 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.

NOTE: 960920- The Arcom Aim104 Modules were all put together in one manual (2192-08164-000-000), then updated to Issues B and C (2192-08240-000-000 & 2192-08521-000-000). During the lifetime of Issue C it was decided that the Aim Module Maual should be split into separate Datasheets [ECO 2679]. Hence, The Revision History for Issues A, B & C of the manual refer to the Aim Module Manual as was.
