Interfaces and connectivity

The TRB246 gateway is equipped with one Ethernet port, RS232 and RS485 serial interfaces, and I/O channels routed to a 16-pin terminal block. The terminal block also provides GPS output. This combination of interfaces enables the gateway to act as a communication bridge between diverse industrial devices and cellular networks.

Support for DNP3, DLMS and Modbus protocols ensures compatibility with common industrial automation and utility metering standards. This makes the TRB246 ideal for M2M communication tasks that require data transmission from serial and I/O devices over cellular connections.

Cellular connectivity and failover

The TRB246 operates on 4G/LTE Cat 4 networks with fallback to 3G and 2G. Dual SIM functionality combined with automatic failover and backup WAN ensures uninterrupted connectivity if the primary link fails. The gateway supports various channel-switching scenarios to enhance data transmission reliability in industrial deployments.
