1.Net Transparent Transmission Mode of Industrial Modem USR-G785-E
Mode Declaration
net transparent transmission mode
In this mode, the serial port device can send data to the specified server on the network through this module. The module can also accept data from the server and forward the information to the serial port device.
Users do not need to pay attention to the data conversion process between serial port data and network packets, only through simple parameter settings, data transparent communication between serial port devices and network servers can be achieved.
This module supports two Socket connections, Socket A and Socket B, which are independent of each other. Socket A supports TCP Client, TCP Server and UDP Client. Socket B support TCP Client and UDP Client

2.UDC Mode of Industrial Modem USR-G785-E
Mode Description
UDC mode
In this mode, the user's terminal device can send the request data to the specified https server through this module, then the module receives the data from the https server, parses the data and sends the results to the serial port device.
Users do not need to pay attention to the data conversion process between serial port data and network packets, only through simple parameter settings, can realize the serial port device to https server data request.
