Configuring the Communications Controller
This chapter explains the communication parameters of the
Communications Controller and describes how to set them. System
integrators need this information to configure the Communications
Controller for the host system.
The Communications Controller has two modes of operation, run mode
and configuration mode. During normal operation, the Controller functions
in run mode. When the Controller is in configuration mode you can change
the communication parameters using the push buttons and displays located
at its left end. Any changes you make to the parameter settings do not take
effect until they are saved, which returns the Communications Controller
to run mode. While in configuration mode the Communications Controller
continues to communicate over its ports according to its previous settings.
Important: Verify all parameter settings before connecting the
Communications Controller to your network. Incorrect settings may cause
unreliable and unpredictable operation of the network.
Parameter settings are saved in non-volatile memory so that you do not
lose them even if power to the Communications Controller is interrupted.
Whenever the Communications Controller is in run mode, the seven
segment display is off to conserve power.
Important: If the Communications Controller displays symbols other
than those shown in this chapter, it is malfunctioning. Contact your A-B
representative to arrange to return the unit for servicing.
Displays
Figure 3.1 shows the configuration displays on the left end of the
Communications Controller. The left display (one digit) shows the number
of the communication parameter being configured. The two right displays
(two digits) show the current setting for that parameter. Communication
parameters are configured in two menus, a main menu for basic
parameters, and a sub-menu for more advanced parameters for the
RS-232C port.
