Using 8-Pin RJ-45 Connectors

Use this procedure to configure devices to use alternate wiring if you will be using 8-pin RJ-45 plugs with Digi's 10-pin RJ-45 jacks. This procedure uses a ditty parameter, altpin, to enable the use of 8-pin RJ-45 connectors. This is accomplished by swapping the functions of the DCD and DSR inputs so that DCD becomes available on pin 1 of an 8-pin RJ-45 connector. 

Procedure

1. Enter the following command at a command prompt:

   ditty altpin [device_name]

   (in AIX, use /usr/Lbin/tty/stty-digi altpin [device_name])

   where device_name is the name of the TTY device on which you want altpin activated. If no device is specified, the command acts on stdout.

2. Repeat Step 1 for all devices that require altpin. (The commands may be added to a startup script to cause them to run automatically whenever the system is started.)

   To cancel altpin, enter the following command:

   ditty -altpin [device_name]

   (in AIX, use /usr/Lbin/tty/stty-digi -altpin [device_name])
