Category: USB Interface Module

This is an industrial grade 4G DTU which incorporates Qualcomm platform 4G communication module SIM7600E-H. It supports multi-mode multi-band, and suits multi countries or regions. After our secondary development for the module firmware, it takes only some simple configurations to achieve bidirectional data transparent transmission between RS232/RS485/TTL serial port and 4G LTE network.

With features like four modes support (TCP/UDP, Modbus, HTTP, and MQTT), RNDIS dial-up, and GNSS positioning, this industrial-grade DTU is designed to be fully functional, easy to use, and stable operating. It would be an ideal choice for fields including industrial data collection, communication, remote control, and other IoT applications that need high throughput 4G data communication and have high requirements of data rate and latency.



Supports USB, UART/RS232/RS485 Communication
4G/3G/2G Dial-Up & GNSS Positioning, Global Band Support
