type SJT power cord with grounded connections on both ends
must be used. Always use with a grounded socket outlet. Do not
use a cable that has been damaged.
• An RS-232 serial interface extension cable ("straight-through")
to connect your host computer to the Webster screen in the
console.
A 12-foot (3700 mm) serial cable is included with the IRP 4500,

by Webster to generate carrier detect (DCD). For further
