Teltonika TRB145 – Linux-Based Industrial Gateway Board, RS485 Interface

The industrial LTE Cat 1 gateway board TRB145 is equipped with an RS485 interface, digital inputs/outputs and a micro-USB port. TRB145’s compact design makes this gateway perfect for applications, in which a sole device must be remotely controlled over an RS485 interface. TRB145 is engineered to be used in industrial applications, therefore it has a wide range of software features such as SMS control, firewall, OpenVPN, IPsec, RMS and FOTA support.
