Configuring the Communications
Controller
Chapter 3
3-6
Pressing only the EXIT button while in the sub-menu takes the
Communications Controller back to the main menu. You can move
between the two menus as much as you need to during any given
configuration session.
Important: If the Communications Controller is left inactive (i.e., with no
buttons pressed) in configuration mode for 3 minutes, it returns to run
mode. Any changes made since going into configuration mode will not be
saved. Also, if power to the Communications Controller is interrupted
while in configuration mode, any changes made will not be saved.
Setting Factory Defaults
Pressing the VIEW and DATA buttons simultaneously when in
configuration mode resets all parameters in both menus to their factory
defaults. When this button combination is pressed, the Communications
Controller displays the first parameter and its factory default.
Like any other changes, the factory default parameters are not saved until
the VIEW and EXIT buttons are pressed simultaneously. If only the EXIT
button is pressed, the Communications Controller returns to run mode
without changing the parameters to their factory defaults.
For normal operation, you must configure the basic communication
parameters. For special communication needs you can configure the
advanced communication parameters, which provide more flexibility in the
RS-232C operation of the Communications Controller.
Basic Parameters
The basic communication parameters are divided into two groups:
those that control the Remote I/O link
those that control the RS-232C link
The parameter number is shown in the left display with the current setting
in the two right displays.
Table 3.B describes each basic communication parameter and its valid
settings.
