4.2.1.5 Accessory Cable Wire Color Code and Demo Cable Pinout
The following table shows the wire color code for the 12-pin round connector to unterminated
(“blank”) accessory cable and the pinout to the demo cable, which terminates in a 15-pin
female D subminiature connector (DB15f); see section 4.2.2, “Integral Cable” for a diagram
showing the DB15f orientation. The cable contains fifteen conductors; however, only twelve
conductors are connected to pins on the round connector and DB15f. Ten of the fifteen con-
ductors in the cable are wired as 100 ohm twisted pairs, as shown in the table. One of the fif-
teen conductors is a non-insulated drain wire that is shorted to the foil shielding in the cable.
This drain wire is not connected to the round connector or DB15f connector.
4.2.2 Integral Cable
The QTERM-G56 can be optionally equipped with an integral cable (instead of the 12-pin
round connector). This cable is terminated with a DB15f connector. Figure 23 shows the inte-
gral cable connector orientation.
