7.2 COMMUNICATION CABLES

Communication with payloads is accomplished via cables provided for the RS-232C port (for

cabin payloads), and the two RS-422A ports (for payload bay payloads).

7.2.1 RS-232C Cables

Two 14-foot RS-232C cables are provided for experiments located in the orbiter cabin. The

first cable, a DB9 (female) to DB25 (male) part number SED33103335, is fully compatible with

an IBM AT serial cable. The second cable is a DB9 (female) to DB9 (male), part number

SED33103348. Refer to Table 7-I for the proper connector mates. For details of each cable

schematic, see Figures 7-7 and 7-8. RS-232 Y and Quad cables are also provided for

PCMMU PGSC output to experiment PGSC connections.
