Services Screen
Current Pin Status
The Current Pin Status, which shows the state of the RS-232 pins, is also
displayed on the Supervisory interface screen.
DTR Alarm Control and Status Table
In addition to the configurable fields, the Supervisory screen displays a table
that lets you set the Data Terminal Ready (DTR) Alarm Control parameters
and view the current DTR Alarm Status.
Choices for DTR Alarm Control are "Enable" and "Disable"; the default
setting is "Disable." Setting DTR Alarm Control to "Enable" allows the unit
to go into alarm on a loss of DTR, which occurs when the Supervisory port
detects that the DTR signal is low. The DTR Status field indicates the current
state of the DTR alarm.
The Services screen (Figure 3.12) displays the unit's defined services and the
Interface, Type, and Pair parameters for each service.
