Wiring Between FX Systems for Sync
Where multiple floor systems are installed, it may be necessary to install sync wire and network
communication cable between the aisles.
Sync Cable
The sync cable (RF Sync) should be installed between FX systems if the distance between aisles is
under 40 feet. If two aisles are more than 40 feet apart, no sync cable is needed. Use 22 AWG
4-conductor (STP) (5594) cable for sync cable. Follow the Sync Cable Wiring Table below to
wire it to appropriate terminals. Sync cables are wired in daisy chain style. There are two sync
cables in a PAB antenna, the input cable and the output cable. The first antenna only uses Sync
Output cable, the last has the Input sync cable. The Output cable connects from terminal (J22) to
Sync Input terminal (J20) on the synced system.
Please refer the table below for Sync wire terminal connector pin assignment.
