EmberNET Relay Bridge 4G

Bridging a serial device to a cellular network usually means picking between USB and RS-232/485, but the Relay Bridge 4G does not force that choice. This industrial 4G DTU (Data Transfer Unit) connects over USB, RS232, or RS485, all from the same unit, and hands off whatever comes in to a global-band 4G/3G/2G connection, no host computer required in between. It's built for the kind of unattended field deployment where a PLC, sensor, or legacy serial device just needs a reliable path onto the cellular network. Positioning support runs deep, with GPS, BeiDou, GLONASS, Galileo, QZSS, and LBS base station fallback all included. An onboard MCU acts as a hardware watchdog, automatically rebooting the unit if it hits an exception, which matters most in unattended installs where nobody's around to power-cycle it. Multiple protection circuits (ESD, anti-surge) keep it stable against electrical noise, and the aluminum case is built to shrug off the conditions field deployments actually see. Running on a wide 7 to 36V DC input and rated for -40°C to 80°C, the Relay Bridge 4G is equally at home in a remote cabinet, a vehicle, or an outdoor enclosure. AT command support (based on the 3GPP TS 27.007/27.005/V.25TER standards) makes it straightforward to integrate into existing control software, and Windows and Linux compatibility covers most host environments already in use.
