4. Connect the a 25-pin RS-232 cable to the 25-pin connector on the rear of
the data module.
5. Route the cable through the data mounting and through the twist-lock cable
retainer on the top of the data mounting.
6. Attach the other end of the RS-232 cable to DTE or DCE.
7. Insert the data module vertically into the data mounting. Be sure the display
is to the top of the data mounting.
8. Repeat steps 2 through 5 for each data module.
9. Return the horizontal retaining bar to its original position to secure the data
modules inside the data mounting.
10. Go to the configuration procedure for the data module you are using:
■ Configuring the 7400A data module
■ Configuring the 7400B Data Module
■ Configuring the 7400C HSL (high- speed link) data module
■ Configuring the 7400D data module
■ Configuring the 8400B Plus data module
Configuring the 7400A data module
The 7400A is a full-duplex, asynchronous data module for use with Digital
Communications Protocol (DCP). It is designed for applications that do not require
integration of voice and data. It supports asynchronous connections at speeds up
to 19.2 Kbps through an EIA-232-D interface.
Figure 14 represents the front and
back of the 7400A data module.
