Synchro wiring
Use synchronized (abbreviated “synchro”) wires when installing two or more sets in the same
group by using the SYNCHRO terminal on each transmitter. Synchro wires allow each
transmitter’s frequency to be synchronized at the same starting point to eliminate false
emissions to the receiver. Synchro wires are not required between the receivers. Refer to the
graphic below depicting a synchro wiring connection between two photobeam stacks (a
maximum of 4 stacks are supported).

Synchro wire
The synchro wire should be more than 0.65 mm (22 AWG) and run no longer than 20 m (66 ft)
in length. Synchro wiring should only be wired to the same group (Group A to Group A, or
Group B to Group B), and the connected devices must use a common power supply.
Notice!
The system does not activate when synchro wires are connected improperly. The POWER LED
flashes when the required wires are not connected correctly.
!
Caution!
When the POWER LED flashes, shut off the power and reconnect the wires correctly.
