Cabling Specifications

Cabling Specifications

The tables in this appendix list the pinouts associated with the AccessPro PC card cables, as follows:


Table  A-1: Auxiliary Port Connector DTE Pinout
RJ-45 Normal Function DB-25
1 Auxiliary port RTS 5
2 Auxiliary port DTR 6
3 Auxiliary port TxD 3
4 GND 7
5 GND 7
6 Auxiliary port RxD 2
7 Auxiliary port CD 20
8 Auxiliary port CTS 4

Table  A-2: BRI Port Pinout (RJ-45)
8 Pin1 TE1 NT2 Polarity
3 Transmit Receive +
4 Receive Transmit +
5 Receive Transmit -
6 Transmit Receive -
Caution To prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The Ethernet, Token Ring, and BRI ports all use RJ-45 connectors.

1 TE refers to terminal terminating layer 1 aspects of TE1, TA, and NT2 functional groups.
2 NT refers to network terminating layer 1 aspects of NT1 and NT2 functional groups.

Note All serial cables have a DB-60 connector on the end that attaches to the AccessPro card. The following pinouts represent only the network ends of the cables. Because the pins on the DB-60 connector are small, manufacturing and soldering these cables yourself might be very difficult and is not recommended.

Note In the following tables, serial pinouts for DTE and DCE cables use arrows to indicate signal direction: --> indicates DTE to DCE, and <-- indicates DCE to DTE.

1 A DCE cable is not available for the EIA-530 interface. The EIA-530 interface cannot be operated in DCE mode.
