DTE Connection

Use the following procedures to connect the EIA-232-D cable and ferrite choke from

the modem to the DTE:

1. Make sure the modem’s rear panel power switch is Off.

2. Connect the DB-25 plug on the cable to the DB-25 socket labeled DTE on the

modem’s rear panel. Use a small screwdriver to fasten the cable to the modem.

3. Connect the other end of the cable to the DTE. Use a small screwdriver to fasten

the cable to the DTE.

To ensure compliance with FCC Part 15 Regulations, a ferrite choke must be installed

on the EIA-232-D interface cable.

1. Open the ferrite choke and place it around the DTE cable as close as possible to

the connector attached to the modem.

2. Close the two halves around the cable and snap the ferrite choke shut, pressing

down on the plastic latch to secure it.

3. Install a cable tie behind the ferrite choke to prevent it from sliding along the cable.
