4G Wireless Routing DTU User Manual
Shang Hai YUGE Information Technology co., LTD
2.5 Application setting
The main function of DTU is to use TCP to transparently transmit serial data and server
data. This function receives the RS232 serial port data, transmits it to the set server, and can
receive the data on the server and transfer it to the device on the RS232 serial port.
The RS485 transparent transmission setting function is basically the same as RS232.
Since RS485 is half-duplex, it is not possible to transparently pass server data to the serial
port. If you need to modify this feature, please contact your supplier.
