Configuring the 8400B Plus data module
Figure 17 shows the rear of a 8400B Plus asynchronous data module. The unit
provides integrated voice and data communications over standard, 2-wire,
twisted-pair circuits within 2000 ft. of an DEFINITY. The unit can emulate a
Hayes-compatible interface for standard personal computer (PC) communication.
The options for the 8400B Plus are set from the rear panel interface.

Installing required configuration equipment for the 8400B
Before you can enter configuration commands, you must first connect a terminal
or a PC with a keyboard, monitor, and terminal-emulation software to the data
module. Proceed as follows.
1. Connect one end of an RS-232 cable to an RS-232, serial-communications
port (often called a COM port) on the terminal or PC.
2. Connect the other end of the RS-232 cable to Port 1 of the data module
3. If you are using a PC, start your terminal emulation software.
Selecting 8400B options
On the 8400B data module, all configuration options are enabled by default. You
configure the 8400B by disabling options with a code that you enter in a memory
register (S24) in the data module. Consult the table below, and perform the steps
that follow.
