RS232 Serial to Cellular Gateway


Effortlessly connect your serial RS232 based industrial devices and remotely monitor from cloud dashboard with our 4G/2G enabled cellular gateway.

This industrial-grade wireless gateway can connect to any RS232 enabled device that requires seamless and periodic supervision from remote central server with fewer configurations. It uses public cellular network (2G/3G/LTE) for long-range data transmission enabling remote monitoring from a central server.

It is capable of supporting any type of serial protocols such as Modbus RTU/ASCII, custom request/response and produce/consume. This device can also operate as an MQTT/HTTPS gateway that ensures secure data communication between your device and cloud server.
