## Teltonika RUT142 Wi-Fi 4 Router, 2 x 10/100 Mbps Ethernet ports, Modbus, DLMS, DNP3, RS232

The Teltonika RUT142 is the RS232 sibling of the RUT140: the same compact industrial NAT/isolation Ethernet router (again, no cellular modem), but with an added RS232 serial port for interfacing with legacy serial equipment such as PLCs and meters. It's aimed at the same DIN-rail industrial automation use cases, adding Wi-Fi 4 as a secondary connectivity option and full support for Modbus, DLMS and DNP3 over both Ethernet and serial.
