DB-9 Connector Pin-outs

The DB-9 connector is reserved for factory use only.

RJ-45 Connector

RJ-45 connector pin-outs are illustrated in Figure 7.

Because both RJ-45 connectors have the same wiring pin-outs, they require the same “flipped” cable. In other words, the IN connector requires a “flipped” cable for connecting the first unit to the CC1, and the OUT connector requires a “flipped” for cascading other units. A “flipped” cable is as follows: Pin 1 of the cable at one end becomes pin 8 at the other end. Refer to Figure 8.

Note that the active pin-outs are associated with the outer four pins; namely, 1, 2, 7 and 8. All accessories on the System 9760 require the “flipped” cable to be used to attach periph- eral equipment. This presently pertains to the KBD, MXB, CXT, ALM, MDA, CDU-T, VCRC, REL, and VCRC-P units.
