The SIM7600G-H 4G DTU module is designed for industrial applications and can be directly embedded or developed for secondary use. Based on the SM7600G-H communication module, it supports 4G, 3G, and 2G networks in global frequency bands. This DTU supports USB UART interface communication and TCP, UDP, FTP, FTPS, HTTP, and HTTPS protocols. It enables USB-to-4G and UART RS232 RS485-to-4G networking communication. The industrial-grade SIM7600G-H 4G DTU supports GPS, BeiDou, Glonass, GAL LEO, QZSS, and LBS base station positioning. It includes an onboard STM8 microcontroller for hardware watchdog functionality and automatic power-off/restart during abnormal operation. The module supports a 7-36V wide voltage range power supply, suitable for industrial applications. It features protection circuits such as anti-static and anti-surge for stable and safe communication. The SIM7600G-H 4G module supports a baud rate range of 300bps to 4Mbps (default: 115200bps) and AT command control based on 3GPP TS27.007, 27.005, and V25TER command sets. Condition: New Origin: China
