M300-G / M301-G / M301-TG

Industrial 4G LTE Router

M300-G: 1 x WAN, 1 x LAN, 1 x GPS, 2 x RS232, 1 x RS485, DI/DO, 2 x SIM Card Slots,  -20 ~ +70°C

M301-G / M301-TG: 1 x WAN, 3 x LANs, 1 x GPS, 2 x RS232, 1 x RS485, DI/DO, 2 x SIM Card Slots,  -40 ~ +75°C (For M301-G model, the operating temperature is  -20 ~ +70°C.)


Our industrial-grade M300-G / M301-G / M301-TG series 4G LTE Cellular Routers are highly reliable and secure wireless communications gateway designed for Industrial IoT and M2M applications. Featuring the flexible LAN/WAN Ethernet options, the M300-G provides 1-port 10/100 Base-TX Ethernet interface and the M301-G / M301-TG have 3-port 10/100 Base-TX Ethernet interfaces. With GPS function, the M300-G / M301-G / M301-TG series can track accurately the router location and display sync time for quickly managing existing devices. It is equipped with dual SIM that support failover and roaming over to ensure uninterrupted connectivity.

Supporting RS232, RS485 and DI/DO, the M300-G/M301-G/M301-TG series allow you to customize your professional applications in diverse environments. The device is administrated via web GUI, Telnet, SSH v2 and HTTP/HTTPS. It also provides enterprise-grade software features, such as Modbus for SCADA system or M2M connectivity, and MQTT for M2M application. The critical VPN security supports IPSec, OpenVPN, and GRE, etc. to enhance encryption for authentication and transmission for a wide range of applications and vertical machine-to-machine (M2M) markets.

Built for secure and uninterrupted operation in harsh environments, the M300-G and the M301-G offer operating temperature from -20 to 70°C. For M301-TG model, it supports up -40 to +75°C and a flexible input voltage range of 10-32V DC. Having trusted industrial-grade certificates, Proscend M300-G / M301-G / M301-TG series are best choices for mission-critical cellular communications.
