In addition to normal menu operation, entry to this menu
item is gained by using the Alarm function (shift 8) on the
keypad. The presence of an alarm is indicated by one or
more of the Alarm LEDs being illuminated. Pressing
Cancel will return to the menu item which was viewed
when Alarm (shift 8) was initiated.
This menu item is used to both view and clear the
accumulated status changes of the unit.
View History displays a history of 20 status changes in
the unit, including the date, time, and type of change.
The unit also records for viewing the date and time an
alarm became active and when it became inactive, as
well as the date and time of test activation and
deactivation.
To clear the View History display press Clear (shift 9)
with the View History menu active.
Port Status is used to view the signals monitored on
the data ports. For example, an Nx56/64 interface
monitors the RTS, CTS, TD, and RD, along with other
signal lines. When a port is selected, the LCD indi-
cates if the signal is present.
