R718PC-Wireless RS485 Serial Port Transmission

   

This device only supports RS485 serial port transparent transmission (RS485sensor power supply is DC12V), which can send read commands to the sensor supporting RS-485 protocol according to the configured cycle time. The information of sensor reply will be directly reported to the gateway, and displayed in the interface on the gateway. It uses SX1276 wireless communication.
