In this case, the Line Card will hang up, the Comm
LED goes off and the last event received will remain
on the screen until the next line test or until the next
call. If the “Keep display” option is programmed, the
last event will be displayed until the next
communication attempt.
Line #01
1234 56
If there are no valid messages received during the
communication, a “Fault call” message will be sent to
the CPM and the Line Card will display:
Line #01
Fault call
The central station operator can also terminate the
call at any time by pressing the CLR button. The Line
Card will immediately hang up and will display and
forward to the CPM the following message:
Line #01
Operator Cancel
The call will be terminated automatically if there is no
answer for the handshakes, no valid messages are
received within 30 seconds of communication or the
number of incoming events during the current call
exceeds the call limit. The maximum number of
events per call, the answer timeout for the
handshakes and the valid message timeout are
programmable by the user.
Operating in Stand-alone Mode
If the CPM Unit fails to poll the Line Cards, or not
connected, the Line Cards automatically switch to
stand-alone mode, and operate independently
requiring central station operator interaction. If an
event comes in stand-alone mode the operator has to
acknowledge it manually. The event will be stored in
the Line Cards 1600-event buffer, and will be
transmitter to the CPM Unit upon the restoration of
the CPM connection.
Line Card Menu
When the Line Card is in stand-alone mode, the
operator not only can enter the Line Card Menu by
pressing the OK button, but with also the directional
buttons (< >). The operator can program the most
important Line Card Parameters with the help of the
Line Card Menu.
Moving in the Menu
In the Line Card Menu the current menu name is
displayed in the first row of the LCD and the current
menu item in the second row:

To jump to the next or the previous menu item press
the proper directional button. The parameters can

a submenu or to change a parameter, press the OK
button. To exit from a submenu and leave the

The Line Card Number identifies the individual Line
Cards in the system. All the numbers of the Line
Cards have to be unique because the CPM Unit
refers to the Line Cards by their Line Card numbers.
IMPORTANT:
When installing a new Dual Line Card
Module to the system, the proper Line Card numbers
have to be set before connecting the Module to the
communications bus.
