Installing The Ric Ii Motherboard - Simplex 4100ES Installation Manual

13.4.3

Installing the RIC II Motherboard

The RIC II motherboard is installed into a remote transponder cabinet (back box PID series 2975-91xx). Review the following guidelines
before mounting RIC II motherboard.
• If a power supply is installed in the bay, it must be installed on the far right of the bay and any relay modules must be installed in the
slots immediately to its left.
• Relay cards must be installed in the rightmost possible slots. This is necessary to allow for the proper routing of non-power limited
wiring (typically 120 VAC wiring), which could be connected to a relay module.
• If a 4100/4120-0155 SDACT or a 4100/4120-0153 CCDACT is installed in the bay, it must be installed in the far left or far right slot.
Neither of these modules contains the J1 or P1 connectors, which are used to distribute power and communications to adjacent
modules.
Use the following directions and Figure 82 to install a RIC II motherboard into a transponder cabinet.
1. The RIC II motherboard must be installed in the leftmost slot. Orient the motherboard with the connector labeled J1 on the right.
2. Secure the motherboard to the chassis with four torx screws.
3. If you are installing the RIC II in a transponder cabinet with additional bays, you must connect a 733-525 Power and
Communication Harness. Continue to the next topic for instructions.
13.4.4 Connecting the 733-525 Harness
If you need to connect a 733-525 Harness to a motherboard, refer to Figure 83 and follow these steps. Make sure to route the power and
communication wiring on the left side of the bay.
1. Connect one end of the harness to a motherboard in an adjacent bay.
If the adjacent bay is a master controller bay, connect the harness to the P2 and P3 connectors of the master controller moth-
erboard and continue to step 2.
If the adjacent bay is an expansion bay, connect the harness to the P2 and P3 connectors of the motherboard installed in the
leftmost slot. (If a 4100-0155/4120-0155 SDACT or a 4100-0153/4120-0153 CCDACT occupies the leftmost slot, connect the har-
ness to the motherboard in the second slot from the left.) Connect the harness as follows:
a. Insert the harness connector with the blue wire into the P2 connector. Note that the P2 connector has eight pins. Insert the
harness connector on either the top four pins or the bottom four pins, not in the middle.
b. Insert the harness connector with the white wire into the P3 connector. Note that the P3 connector has eight pins. Insert the
harness connector on either the top four pins or the bottom four pins, not in the middle.
2. Connect the other end of the harness to the leftmost motherboard in the next bay, as described below. Make sure to route the
