Installing auxiliary cards
There are three auxiliary cards available for the OmniTrax system. The Network Interface card is
required for all processors that communicate via the Silver Network. The Relay Output card (ROC)
provides an additional 8 relay outputs to the processor. The Universal Input card (UIC) provides an
additional 8 inputs to the processor. A processor can use two auxiliary cards, the NIC and either an
ROC or a UIC. A processor cannot use an ROC and a UIC. The auxiliary cards piggyback onto J1,
the 40 pin socket on the processor card.
