The wRemote-1500-ETH-CN is a “Concentrator” model that does not have physical inputs or outputs. It is solely responsible for developing the network and concentrating the information from the “node” devices
The device has an RS232 and an RS485 port; both are used by the Modbus. It also has a USB port that can be used for Modbus and for device configuration.
The Ethernet port (10/100 Mbps) can be used to configure it or to get the acquired data using Modbus TCP or Modbus RTU/ASCCI over TCP.
