Waveshare RS232 RS485 To RJ45 Ethernet Serial Server, Spec: RS232 RS485 TO POE ETH (B)

Features:
1. A dual serial port device data collector/IoT gateway designed for industrial environments. One RS232 and one RS485 can work simultaneously using one network cable without interfering with each other.
2. It integrates multiple functions, including serial port server, Modbus gateway, MQTT gateway, RS232 and RS485 to JSON, etc.
3. The other Ethernet port can be used as a network switch or cascade, and the PoE function can be equipped with dual power supply.
4. The Ethernet port provides two power supply methods: DC port (outer diameter 5.5mm, inner diameter 2.1mm) and screw terminal.
5. The chassis adopts guide rail support, which is small in size, easy to install and cost-effective. 6. Suitable for data collection, IoT gateway, security IoT, smart instrument monitoring and other applications.
7. This product is a PoE receiving device (PD) and needs to be connected to a PoE power supply and obtain power from the PSE device to work properly.
