How to Use:
How to Use(>=2pcs):
1. 2PCS: Ordinary , module 1 and module 2 send data to each other.
2. 3PCS: Relay , 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: Master slave network , one as the master device and the other as the slave device.
The way they work and the wired RS485 bus. The master device sends data, and the slave devices receive data. Any slave device sends data, the master device and other slave devices can receive. Once only one device(master or slave) was allowed to transmit data.

packing list:
1 x Transceiver
1 x Antenna

Notice:
Please do not exceed the working voltage, otherwise will break down the circuit board.
