View History

This menu item both displays and clears the accumulated sta-

tus changes of the unit.

View History displays a history of the first 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 inactive, as well as the date and time of test activa-

tion and deactivation.

To clear the View History display, press

Clear (Shift+9)

with the

View History menu active.

Port Status

Port Status displays the signals monitored on the data ports.

For example, the Nx/DBU interface monitors the RTS, CTS,

RD, and TD, along with other signal lines. When a port is

selected, the LCD indicates if the signal is present.

The base Nx interface offers the status screen listed in this sec-

tion. When using other option cards, refer to the appropriate

separate manual for a definition of any status screens offered.

The Port Status of Nx/DBU is examined as an example of how

to use this item. The DBU feature is only for the TSU 100e.
