5.1 External Synchronization Mode with cable (up to 25 systems by
230V 50Hz main power or up to 25 systems 120V 60Hz main power) :
The Master system is usually the antenna closest to the 230V 50Hz or 120V
60Hz power plug. Connect The RG174 synchronization cable from
Synchronize Out connector (master board) to Synchronize In (Slave board) and
to the next Slave system. Switch 1 should be in position ON for master board
and OFF for slave board.
When properly connected, the EXT SYNC LED of all the slave antenna boards
should be lighting excluding the master system’s LED which should be off.
Please ensure the cable is connected properly in polarity. Else the slave
systems’ Ext Sync LED is not lighting after connection.
If the EXT SYNC LED is twinkling, turn the VR1 of previous board to
make the EXT SYNC LED stable. Turn the VR1 to make sure each board has
no more than two noise LEDs.
If more than 5 systems are synchronized by cable, at each 5th system,
the Switch 3 (Synchronize Increment) should be in position ON.
5.2 Supply Synchronization Mode (up to 4 systems by 230V 50Hz main
power or up to 4 systems 120V 60Hz main power) :
Turn VR1 to make sure that its noise level is lowest. This synchronization is up
to support 4 systems on same power line or 2 systems on separated power
line.
5.3 Deactivator Synchronisation
For Sidep Pulse deactivator SDP82 the EAS systems should be synchronized:
Trimmer method:
