Connectivity & Interfaces
The TRB246 provides a single Ethernet port alongside I/O and serial interfaces through its 16-pin terminal block, which carries I/O, RS232, RS485, and GPS connections. This combination of cellular backhaul and wired interfaces makes the gateway suitable for industrial equipment that relies on serial communication and I/O alongside 4G connectivity. Dual SIM slots with auto-failover and backup WAN support ensure the connection remains available when the primary cellular link is lost.
