4 I. Introduction This document describes the specifications and functionality of Tenta s AI/O board 3U CompactPCI form factor. This board was designed as general-purpose data acquisition board suitable for automatic test, measurement and analysis applications. The board is comprised of 32 single ended analog inputs and 16 analog outputs with 12-bit resolution. Analog circuitry is isolated optically from the CompactPCI signals and power. The board form factor, physical dimension and BUS interface comply with CompactPCI Specification PICMG 2.0 R2.1. The I/O and power signals are distributed through J2 rear connector. The board complies with Y2K requirements. AIAO-0700 User Manual Page 4 of 19

12 G. Watchdog timer The Watchdog timer insures that the AI/O board communication with the SBC is alive. The watchdog timer must be reset periodically with the interval configured by software. If a time-out occurs, all analog outputs are set to zero volts. On time-out the watchdog timer latches on watchdog fail state until it is initialized by the SBC. On board jumper (JP3), allows to by-pass this feature (for debugging purposes). H.

15 VI. On Request Built in test (ORB) The AIO700 implements a loop back mechanism to allow on-line testing of the hardware. The board enables to loop some of the analog output (DAC) values and other entities back to the input channels (ADC). The following entities can be tested: Entity Loop back bit (DAC control bit 5) Input Channel (DAC control 0-4) Expected Value AO Channel Last write to this channel AO Channel Last write to this channel AO Channel Last write to this channel AO Channel Last write to this channel Reference Voltage V High GND 1 8 0V AIAO-0700 User Manual Page 15 of 19

16 VII. Register Definition On power-up or system reset, all on-board control registers are reset to 0. This sets the analog input channel to first channel (0), sets the analog input range to ±5V, and sets all the analog output channels to 0V.

17 VIII. Test Procedure The functionality of all analog outputs and analog inputs are examined by an automatic test procedure (ATP). Each analog output is connected by an external loop back connector to two analog inputs. The automatic test checks the accuracy of each analog I/O, full scale error, offset error and watchdog mechanism. AIAO-0700 User Manual Page 17 of 19
