A unique feature of the VMIVME-4100 is the Built-in-Test logic that allows

the testing of any one of the analog output channels through the use of an onboard multiplexer and the VMIVME-3100 ADC Board. When in test mode, the field

connections through connector P3 may be isolated and any of the 16 channels

may be routed to the 12-bit ADC Board via VMIC’s Analog Backplane (AMXbusTM).

An ADC Board under program control may have the analog signal converted to a

12-bit digital word and compared with the original 12-bit word written to the DAC

Board. In this manner, each of the 16 analog output channels may be verified

without disturbing the field connected devices. The analog output channels may

also be multiplexed to the Analog Test Bus, simultaneously controlling the P3

connected field devices, providing real-time fault detection of the outputs. If a board

fails its self-test, a Fail LED on the front panel may be turned on to indicate the

board is in a failed condition. The complete operation and requirements for the

self-test mode are explained in detail in this manual in Section 3, Theory of

Operation, and Section 4, Programming.
