Ethergate 3-AC Interface Definition Description Net Name Signal Type Comment AC Power Input Power 100～240VAC Input AC Power Input Power RS485_B- RS485 B- It is used to prevent interference, left floating. In COM Signal Power case of connection, connect to ground at only one point.
- Page 8 ETHERGATE 3_ENG 2.2. RS485 Interface The RS485 port uses two wires, A(DATA+), B(DATA-). Connect all A(+) devices to the A(+) terminal and all B(-) devices to the B(-) terminal to communicate. To avoid possible noise in the cables, it is recommended to use shielded cables and to connect the shield at a single point to the protective earth.
