RX 4-POSITION DIP SWITCH
TX-ONLY
TERMINAL
All DIP positions set to ON: alarm relay deactivated. This setting is used when the column
has only transmitter optics
1 CH 1
Wired synchronization: normal receiver operation
Optical synchronization: operation with reception frequency 1
2 CH 2
Wired synchronization: no operation
Optical synchronization: operation with reception frequency 2
3 CH 3
Wired synchronization: no operation
Optical synchronization: operation with reception frequency 3
4 CH 4
Wired synchronization: no operation
Optical synchronization: operation with reception frequency 4, only 2 receivers active
JUMPER J7
If the disqualification function has been activated on the 12-POSITION DIP SWITCH by setting DIP 5 to ON, in
some particular cases and geographical areas it can be useful to increase the disqualification sensitivity by setting
jumper J7 to ON
TX 4-POSITION DIP SWITCH
TEST TX
Setting all the DIP positions to OFF switches off all transmitters on the column; setting all
the DIP positions to ON activates all the transmitters at high frequency in order to allow
initial visual contact between transmitter and receiver, in the case of difficulties at great
distances.
