PRE-INSTALLATION
Rotary Address Switches
- Set the board address for each OCM-16 using both of
the ten-position rotary switches located on the board (See Figure 2). Each of these
addresses must be a sub-address of the NIC-C and must be the same as the ad-
dresses assigned in the Zeus Programming Tool.
S1/S2 LED, Incandescent/Relay Select Switches
When LEDs are used, open corresponding dipswitches on S1 and S2 (Refer
to OCM-16 Switches Table) to provide a current limiting resistor of 2.7K
ohms to each LED.
When incandescent lamps or relays are used, close corresponding
dipswitches on S1 and S2 (Refer to OCM-16 Switches Table) to bypass the
limiting resistors.

INSTALLATION
An OCM-16 may be installed in a REMBOX. When using REMBOX 2 or 4, mount the
OCM-16 in one module space on a REMBOX2-MP, P/N 500-634211 or REMBOX4-MP,
P/N 500-634212 using the four screws provided. (Refer to REMBOX2-MP/REMBOX4-
MP Installation Instructions, P/N 315-034211.) Up to 4 OCM-16s will fit in a
REMBOX2; up to 8 OCM-16s will fit in a REMBOX4.
WIRING
Disconnect BATTERY and AC prior to working on equipment.
Each OCM-16 module is a node in the CAN bus.
The OCM-16 can be installed with or without an RNI. Connect 24V and
CAN bus as shown in Figures 2 and 3.
Up to 99 CAN modules, in any combination, can be connected to the CAN
bus of each NIC-C.
Each OCM-16 module is shipped with one CCS cable.
Cable connections for OCM-16 modules are shown in the following table:
