Rockwell Modem Installation

The Rockwell Modem provides a high speed

synchronous serial interface between the CNI GETC and

the CEC/IMC’s Uplink. The CNI GETC uses the modem to

send and receive serial digital data representing GID

information, polling messages, keying messages, and

channel assignments. Data transfer rates are typically 9600

bits per second (bps) using 3002 grade four-wire audio

lines. Additional information on installing and testing the

modem may be found in LBI-33031, LBI-38894, and LBI-

38822.

Install the Rockwell Modem using the following

procedure:

1. Insert the Rockwell Modem into J3 on the GETC

Board and align the mounting holes over the

GETC shelf standoffs.
