FOR USR-G781 Industrial RS232/RS485 Serial to 4G LTE DTU Modem with Ethernet Port - Transparent Data Transmission

The FOR USR-G781 is an industrial DTU modem built for transparent data transmission, enabling RS232 and RS485 serial devices to communicate over 4G LTE networks. It acts as a serial-to-4G LTE gateway and also provides an Ethernet port for LAN connectivity and integration into existing networks. Designed for reliable industrial use, this unit forwards serial data without protocol conversion, preserving the original serial data stream while bridging to cellular or Ethernet links. Ideal for remote monitoring, telemetry, and any application requiring secure, transparent serial communication over 4G LTE with added Ethernet support.
