User terminal address setting

Once the keyboard has been connected to the device, run the following procedure:
1) Press and hold [UP]+[DOWN]+[ENTER] at the same time for at least 3 seconds to enter configuration mode. A
mask is displayed with the cursor flashing in the top left corner.
2) Press [ENTER] once to modify the address of the terminal (display address setting). The cursor will move on
the address field.
Press [UP] or [DOWN] to select the required value of the address and then press [ENTER] again to confirm.
The value will be saved in the permanent memory of the terminal.
3) The appearance of the next mask indicates that the keyboard address has been set.
4) If an empty mask or a mask showing "NO LINK" appears after pressing [ESC], it means that the keypad is not communicating
with any boards. It is necessary to set the address of the board or configure the local network (LAN).
ATTENTION
This is a time procedure; hence if the parameters are not set in a few seconds, the display turns off. In such case, repeat the
process.

SHARED USER TERMINAL

The shared user terminal (address 32) is managed by the application as follows:

Usually, it displays the information regarding the unit selected by the user by pressing [ESC] and [ALARM] simultaneously. Whenever this is
done the terminal switches onto the upper unit address.

In case of maintenance alarm or signal on any of the units connected to the LAN network, the user terminal automatically switches onto the
alarm/maintenance unit, in order to allow proper signalling.
Physically, the shared terminal may be connected to any of the network boards; moreover, it may be connected both on the unit (panel terminal) or in
remote position (wall terminal).
