PDI Configuration

Configuring Other Cards

P4/P5: The PDI can be configured to draw its power from different sources via P4 and P5.

•To draw power from an XPS on the PDI, set jumpers on P4 and P5 to position 2

– 3.

•To draw power from P1 (from the previous PDI or SPS), set jumpers on P4 and P5 to position

1 – 2 (default).

•To remove power from the PDI, remove the jumper from P4.

Refer to the appropriate installation instructions to configure other cards that are located in CPU and expansion bays. The 4100U ones are included in this manual. Refer to Appendix D for a list of publications.

Step 4. Interconnecting Modules and Bays

Overview

Guidelines

Each card has to be interconnected with every other card in its bay. At the same time, bays in the FACP also have to be connected together. Read this section to ensure that cards and bays are interconnected. Refer also to drawings 1976-136 and 1976-137.

Review the following guidelines before interconnecting modules and bays.

•The SPS provides 24 V power to the CPU motherboard.

•The CPU motherboard provides 8 V (3 A capacity) for use by Legacy 4100 slave cards. 24 V card power is routed through the motherboard for slave card use.

•4100 internal comms and power are harnessed to other bays. Do not connect the 8 V at P7 to an 8 V converter on a Goldwing or remote interface card.

•24 V Card power from the SPS is rated at 2 A.

•The 4-wire coms and power harness carries only the 24 V Card supply to a PDI, and not the 24V Signal supply.

•Some of the wire harnesses supplied with cards are not required. It is recommended to store these spare harnesses in case of future requirements.
