2192-09190-000-000 AIM104-MULTI/IO 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-MULTI-IO is an 8-bit PC/104 module providing 8 opto-isolated digital inputs, 2 analogue outputs (Voltage or Current Loop) and 16 single ended or 8 differential analogue inputs. The module provides up to 1000V electrical isolation between your PC/104 based control system and the electrical system under control. Isolation between adjacent channels is limited by the wiring and connectors to 30V. The module is supplied in three configurations: AIM104-MULTI-IO Module fitted with digital inputs, analogue outputs and analogue inputs. AIM104-ADC16/IN8 Module fitted with digital inputs and analogue inputs only. AIM104-DAC2/IN8 Module fitted with digital inputs and analogue outputs only. The board includes jumper options for selecting all analogue inputs as 16 single ended or 8 differential. All digital inputs include a fixed 10ms debounce filter.

When an input is switched ON, the value read by the host will be �0�. Each input is configured as follows: DAC Operation DAC data is written to DAC L-byte and DAC H-byte registers in accordance with the I/O map. Bit�s 4 - 7 of the H-byte designate the DAC channel number, A value of �0� in this position writes the data to DAC channel 0 and a value of �F� writes the data to DAC channel 1. The �BUSY status� register must be checked and the �BUSY� flag bit clear before a new value is written. Page 3 2192-09190-000-000 J541 AIM104-MULTI/IO ADC Operation ADC conversion is initiated when multiplexer channel data is written to the �ADC channel and start conversion� register. Conversion data may be read from the ADC L-byte and ADC H-byte registers when the status bit in the �BUSY status� register indicates that a conversion is complete. Only the �BUSY status� register and the �opto inputs� register should be accessed while the board is in the Busy state. Accessing other registers before the status bit is cleared for both ADC and DAC cycles may result in data corruption. ADC Input Range The standard analogue input range for the AIM104-MULTI I/O and AIM104-ADC16/IN8 is –5V. Signals with greater span than this , such as –10V, can buffered with a simple amplifier circuit. The values shown below are suggested values only, and may be varied to suit the application. +12V 2R + AIM104-MULTI I/O DIFFERENTIAL ± 10V SIGNAL input INPUT 2R - C R = 100k -12V R C = 1μF R 0VA C Page 4 J541 AIM104-MULTI/IO 2192-09190-000-000 Links The base address of the module is set using LK1; inserting a jumper selects a �0� for the address line value.

Periodically the calibration may be checked and if required adjustments to the on board reference can be made. Adjust the multi turn trimmer VR1 while monitoring TP10. The voltage at TP10 should be 5.0v. Further calibration is achieved through software. EMC Issues The opto-isolation provides a good barrier for noise emissions generated by the high frequency host PC/104 system. The AIM104-MULTI-IO includes additional components on board to minimise high frequency noise transfer. This filtering 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 transient (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.

Issue D V1 I3 980303 [ECO 2679] (Manual split up into Datasheets.) 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.
