8.1 DTU
RS232 provides full-serial communication, enabling hardware-based traffic control.
RS485 provides half-duplex communication, enabling remote transmission of serial communication
data.
Method for setting web pages when the gateway is used as a DTU:
1. Enable DTU 1 (RS232) or DTU 2 (RS-485).
2. Set the connection parameters of the gateway interface and industrial device. Communication is
available only when the parameters at both ends of the network link are consistent.
3. Set the IP address and transmit protocol (TCP or UDP) of the server.
