USR-G785 is an industrial 2G/3G/4G LTE Modem with high stability and anti-interference. It can realize the data transparent transmission between serial port RS232/RS485 and wireless network. The two-way data transmission from serial port to network server can be easily realized by setting simple AT commands.
- European version
- Supports 2G/3G/4G network
- SMS command or confirmation by SMS
USR-G785 is an industrial wireless data transmission terminal with high stability and anti-interference. It can realize the data transparent transmission function. The two-way data transmission from serial port to network server can be easily realized by setting simple AT commands.
USR-G785-E is a product developed for serial devices and network servers to transmit data to each other. With simple AT instructions, it is easy to use this product to realize two-way data transparent transmission from serial port to network.

Structure function diagram
The following diagram is a block diagram of the function of the modem.
Network transparent transmission mode
Serial devices can send data to designated server through modem when work at this mode, modem can also forward server data to serial devices.
4G modem USR-G785 supports two sockets, which are independent of each other.
net transparent transmission mode
In this mode, the serial port device can send data to the specified server on the network through this modem. The modem 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.
In this mode, the user's terminal device can send the request data to the specified HTTP server through this modem, then the modem receives the data from the HTTP 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 HTTP server data request.
