Cables and Loopback Plugs

This section describes how to make cables for connecting the AR router to networks, terminals, and printers. It also describes loopback plugs, which are required for testing most router interfaces.

RS-232 Terminal and Modem Cables

The following tables list the wiring diagrams to follow when constructing terminal and modem cables for various connector and port combinations for asynchronous ports.

■For AR725, AR745 and AT-AR024 asynchronous ports see Table 10.

■For AR750S, AR750S-DP and AR770S asynchronous ports see Table 11.

RING input The RING input is only available on asynchronous ports on expansion cards. It is not available on asynchronous ports on base CPU boards.

An alternative method, for both terminal and modem cables, is to wire an RJ-45 patch cord (a straight pin-to-pin cable with RJ-45 connectors on both ends) and then use an RJ-45-to-DB25 adaptor wired internally as a crossed cable. These adaptors are available in DB9 and DB25 female and male versions from data cabling suppliers, and are supplied with wires terminated on the RJ-45 socket and pins on the free ends. The pins are inserted into the appropriate positions in the DB9 or DB25 shell.
