TRB255 може да се користи за интегрирање на модерната и наследна индустриска опрема во едно решение преку RS232, RS485 и Ethernet интерфејси.
Овој индустриски LTE Cat M1 и NB-IoT портата е наназад компатибилен со мрежите EGPRS (2G). Сè уште може да се користи со 2G мрежа, но во случај да се исклучи, постои можност да се префрлите на опциите за поврзување LPWAN.
TRB255 има широк опсег на индустриски и мрежни функции како што се Modbus, SMS контрола, Firewall, OpenVPN и многу повеќе.
Овој производ е компатибилен со системот за далечинско управување на Teltonika Networks (RMS).
