Installing auxiliary cards
OmniTrax Product Guide Page 183
Auxiliary card installation procedure
1. Insert the 40 pin header on the solder side of the expansion card into J1, the 40 pin socket, on
the processor. Ensure that all pins are properly inserted and the four mounting holes on the
auxiliary card align with the four standoffs on the processor.
2. Using the supplied hardware, secure the auxiliary card to the four standoffs.
3. Piggyback the second auxiliary card onto the first auxiliary card by inserting the 40 pin header
on the solder side of the second card into the 40 pin socket on the first auxiliary card. Ensure
that all pins are properly inserted and the four mounting holes on the upper auxiliary card align
with the four standoffs on the lower auxiliary card.
4. Secure the upper auxiliary card with the supplied hardware.
5. Make the wiring connections as indicated in Figure 163:
and Figure 164:.
Network Interface card
You require a network interface card (NIC) if your OmniTrax processor will communicate on
Senstar’s Silver Network. There are five variants of the NIC, each specific to the network
transmission media (P/N 00BA03xx):
• 00BA0301 multi-mode fiber optic cable
• 00BA0302 EIA-422 copper wire
• 00BA0303 single-mode fiber optic cable
• 00BA0304 combined EIA-422 copper wire and multi-mode fiber optic cable
• 00BA0305 combined EIA-422 copper wire and single-mode fiber optic cable
The -01, -02, and -03 variants are based on a single network transmission media. The -04 and -05
variants enable an EIA-422 copper wire/fiber optic cable mix (see Figure 163:
). You make the EIA-
422 wiring connections on removable terminal blocks. The screw terminals accept wire sizes from
12 to 24 AWG, with a 6 mm (1/4 in.) strip length. The fiber optic variants use ST connectors.
CAUTION Both the processor and auxiliary cards include static sensitive
components. Follow proper ESD procedures when handling the cards.
Disconnect all power sources before installing an auxiliary card.
Note If two auxiliary cards are being installed on this processor, install the
NIC first, with the ROC or UIC piggybacked on top.
Use the supplied standoffs to secure the NIC, then use the standard
mounting hardware to secure the second auxiliary card.
Note Do not use a mixed media NIC to connect a Network Interface Unit to
an OmniTrax processor, which will communicate with the other
processors over the sensor cables.
