a. Insert one end of the second D8W cord into the jack on your
7400-series DCP voice terminal.
b. Insert the other end of the second D8W cord into the jack on
the rear panel of the Data Module labeled PHONE.
Note: An internal DIP-switch must be set correctly for
this option to work (see "Setting the Hardware
Option Switches" in this chapter). Also, if your
voice terminal has data capabilities, the data
features of the voice terminal are not supported
while it is connected to the 7400B Data Module.
Connecting the Power Connect the separate power supply unit to the 7400B Data Module as
supply follows:
1. Insert the output connector of the power supply into the connector
on the rear panel of the Data Module labeled “POWER.”
Caution: Be sure that the side of the power supply cable
connector labeled “TOP” is facing upward before
inserting the connector.
2. Insert the AC connector of the power supply unit into an
appropriate AC outlet.
Note: Since the 7400B Data Module does not have a power
on/off switch, the unit will power on as soon as the
power supply is connected to an active AC line.
Caution: Make certain that the AC outlet to which you connect the
power supply is unswitched (for example, not controlled
by a wall switch or light dimmer).
