How to Use: How to Use(>=2pcs): 1. 2PCS: Ordinary transmission, module 1 and module 2 send data to each other. 2. 3PCS: Relay transmission, 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 transmission, 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. Specification: Item Type: Master Slave Network Transceiver Product Material: PCB Product Model: RT18A01 Working Voltage: 5V Working Current: 6-40mA Interface: RS485 Transmitting Power: -40~+20dBm Receiving Sensitivity: -114dBm Working Temperature: -25~75℃ Transmission Distance: Approx. 500meter / 1640.4ft Package List: 1 x Transceiver 1 x Antenna Note: Please do not exceed the working voltage, otherwise will break down the circuit board.
