It suits engineers who need to move remote I/O, Modbus data or camera video off site without a fixed-line connection.A built-in GPS receiver with 32-channel All-In-View tracking and NMEA 0183 output allows the unit to serve as a GPS tracking system. The gateway also offers 4G router functionality and a serial port to 4G gateway function, with Micro SD storage expansion up to 32GB SDHC.The CR ordering code denotes the frequency band version for China. The metal, DIN-rail mountable housing is rated for -25 ~ +75 °C operation and is designed for harsh industrial environments.Applications4G routerRemote video monitoringSerial port to 4G gatewayGPS trackingM2M data transfer of remote I/O and Modbus data

The GRP-540M-4GE CR connects Ethernet, serial and CAN devices to cellular networks, giving engineers a way to reach remote equipment over 4G LTE with 3G WCDMA and 2G GSM fallback. It works as a 4G router with port mapping, and as a serial-to-4G gateway for field devices that have no network connection of their own.The unit adds GPS with 32-channel All-In-View tracking, so it can also be deployed as a GPS tracking node. Remote I/O and Modbus data, or camera video, can be carried over the cellular link, making the device suited to distributed M2M monitoring.Built with a metal casing and rated for harsh industrial environments, the gateway mounts on DIN-rail or by screw. Micro SD expansion and a watchdog timer support unattended operation.Applications4G router for remote sitesRemote video monitoringSerial port to 4G gatewayGPS tracking systemsM2M transfer of remote I/O and Modbus data over 4G/3G/2G

GRP-540M-4GE-WF is a cellular gateway that connects Ethernet, Wi-Fi, RS-232/RS-485 serial and CAN devices to 4G, 3G and 2G networks. It suits remote sites where engineers need to move device data, such as remote I/O or Modbus data, or camera video, over a mobile network without fixed-line infrastructure.Beyond data transfer, the unit includes a 4G router function, port mapping and a serial-to-4G gateway function. A built-in GPS receiver with 32 tracking channels allows it to be used as a GPS tracking system.
