Description
TRB255 Industrial M2M is Gateway packed with all the necessities including: analog and digital inputs/outputs, Ethernet ports, LPWAN modem along with a secured power connector. The device consists of a combination of Ethernet and serial communication RS232 /RS485, which allow easy integration into industrial projects.
This industrial system is backward compatible with the EGPRS (2G) network. It also supports LTE Cat M1, NB-IoT as connectivity options.
TRB255 operates on a wide range of software options including: SMS control, firewall services, open VPN, IP-SEC, FOTA support and Remote Management Services (RMS) to ensure fast and safe transmission of data.
Furthermore, the gateway is used universally in various M2M applications as it is a highly energy efficient tool that supports Teltonika Remote Management System (RMS).
What makes it stand out is its ability to integrate legacy and present-day industrial applications as it can effectively operate on RS232/RS485 serial communication interfaces.
