About the Terminal Device The 7400B Data Module operates with any asynchronous data terminal device that has an EIA-232-D (or RS-232-C) serial port connector. If you are using a PC as your terminal, you will need a suitable data communications software package.

Also, you must set the appropriate configuration options before connecting the 7400B Data Module to a printer or plotter. To do this, connect a data terminal or PC to Port 1 of the data module, change the necessary configuration parameters, remove the data terminal or PC, and then connect the printer of plotter. The configuration parameters used for this type of operation are described in Chapter 4, "Operation and Configuration," in a section titled “Remote Site Use.”

EIA-232-D cables and data communications software packages are described in the following paragraphs.

Selecting an EIA-232-DSelect an EIA-232-D with a male connector at one end to mate with the

CablePort 1 connector of the 7400B Data Module, and a connector of the appropriate "gender" at the other end to mate with the communications port of your terminal device.

Note: Cables with the earlier RS-232-C designation will also work.

The most common EIA-232-D cables are supplied with a male connector at both ends. If you have this type of cable and the EIA-232- D port on your terminal device is a male connector, you can use a cable adapter commonly referred to as a “gender changer”. Otherwise, obtain an EIA-232-D cable that has the appropriate gender connector at each end to fit your application needs.

Selecting DataThe purpose of data communications software is to allow your PC to Communications Software operate as an asynchronous data communications terminal. Of the many

software packages available, all perform essentially the same functions, but often in significantly different ways.

If you do not already have a communications software package, consult with an experienced user for advice on selecting software to suit your data communications needs. The following, though not required, are a few helpful features that you may wish to look for in the software you select:

●Terminal mode. Also called local mode or chat mode, this feature allows you to issue commands to the 7400B Data Module. The software that you select must have some form of terminal mode.

●Dialing directory. This feature allows you to store several frequently called numbers, often along with configuration of the data options needed for completing the connection.
