One RS-422A cable provides a communication link between the PGSC and payload in the
payload bay. This cable connects the PDIP or CIP to the PGSC. The PDIP/CIP connector has
a part number of NLS6GT12-35P and is a male connector. The CIP and PDIP are shown in
Figures 7-9 and 7-10. A DB9-S female connector mates with an RS-422 adapter to the
PCMCIA RS-422 card/cable assembly. In addition, a DB9-S female connector mates with RS-
422A connector located on the Expansion Assembly of the PGSC (Configuration 5). A
schematic of this cable is provided in Figure 7-11.
The RS-422A Y cable is used to transfer information between two or three PGSC’s. A
