Overview:
HY-RS485 series is a low cost, high performance transparent FSK transceiver with operating at 433 MHz. It features small size, high output power, high sensitivity,long transmission distance and high communication data rate with auto set up for communication change and data receiving and transmission control. There is RS485 interface, it is easy to realize the wireless data transmission with only providing the RS485 data. It is flexible for the users to set the RS485(UART) baud rate, frequency, output power, data rate, frequency deviation, receiving bandwidth etc parameters. It is your ideal choice for designing wireless data transmission products which can be widely used on wireless data transmission field.
 
5PCS without distinction of Wireless Data Transmission Module.One as the master device ,four other as a slave device.
Just a simple baud rate settings, can be composed of RS485 wireless network,replace the existing RS485 bus.
An RS485 wireless network, only one master device, up to 32 Slave device.If you need more Slave device(>4pcs), please purchase from here
Working principle:
One as master device,  the other  4 pcs 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 3 slave devices can receive .
When ever only allowed  one device (master or slave) to transmit data.
