Basic Function

USR-G771 quickly delivers the bi-directional transparent transmission of data at serial ports and networks.

• Network Mode

  1. Support European mainstream LTE frequency bands.
  2. Provide wide coverage and high stability based on existing 4G operator networks.
  3. Provide network access through a general 4G network adapter.
  4. Support the GPRS network, and ensure the availability of communication.

• Transparent Transmission mode

  1. The serial device is connected with the network server through G771 to deliver bi-directional transparent transmission of data.
  2. The product supports 4 socket links, and keeps these 4 links independent of each other.

• Registration Package plus Heartbeat Package

  1. A registration package is sent to a server to identify the device, and a heartbeat packet is sent to a server to judge the active state of the device.
  2. A heartbeat packet is sent to a serial terminal to actively collect data.

• Parameter Configuration

  1. Support the parameter configuration of serial, network and SMT AT commands, and provide the configuration tool for the PC.

• Remote FOTA Upgrade.

  1. With the remote management platform, it can realize the automatic firmware upgrade. Have a small upgrade package of differential algorithm, and this can save upgrade traffic and time

Application

• Agricultural IOT Environmental Monitoring

• Transmission of Charging Pile Data Through Internet
