As we all knows, the infrared barrier has two kinds of working methods, that is synchronous working mode and asynchronous working mode.
When the J2 jumper tap is plugged in, that's the default asynchronous working mode, then no need to connect the synchronization wire.
When we take off the J2 jumper tap, then it will change into synchronous working mode. In this way, we need to connect the synchronous working wires.
There are two methods for connection:
1. If the transmitter and receiver use the same power supply, then only need to use a cable to short circuit the RT interface between TX and RX.
Single power supply, synchronous wiring work method
2. If the transmitter and receiver are installed in long distance, they use the different power supply, in this way, not only need short circuit the RT interface, and also need to short circuit the GD interface.
Dual power supply, synchronous wiring work method
After finished the synchronization wires connection, then the infrared barriers can work normally.
