TRB255 TRB255 gate TRB255 is able to connect modern and old industrial devices into one whole via RS232, RS485 and Ethernet connections. This industrial LTE Cat M1 and NB-IoT network interface is backward compatible with EGPRS (2G). You can still use it on a 2G network, but disconnecting it will allow you to easily switch to LPWAN connectivity. Supports 4 GNSS constellations. TRB255 offers a wide range of industrial and networking features to choose from: Modbus, SMS control, firewall, OpenVPN and more. This product works great with the Teltonika Networks remote control system (RMS).
