Recommend to buy more than 2pcs!!!






How to use (>=2pcs):




1 2PCS,Module 1 and Module 2 send data to each other.

2 3PCS,Module 1 sends data, module 2 acts as a repeater (multiple repeaters can be used), and module 3 receives data; delay sending and receiving distance.

3 >=3PCS,One as master device, the other as will be as slave device.
the way they work as well as wired RS485 bus. Master device transmit data, Slave devices all receive data.Any slave device transmit data, master device and the other slave devices can receive .When ever only allowed one device (master or slave) to transmit data.


(Tip: The master and slave devices are self-adapting and no configuration is required.)
