The Teltonika TRB255 All-In-One Industrial M2M 4G/LTE Cat-M1/NB-IoT/EGPRS Serial I/O Cellular Gateway is equipped with LPWAN modem, GNSS receiver, Ethernet port, RS232/RS485 and a durable 16 pin connector block. This Gateway board packs all essential features in one package: secure power connector, I/O ports, serial and IoT communications, fast and a reliable internet connection for industry applications, where long lifecycle is a must. The TRB255 can be used to integrate modern and legacy industrial equipment in one solution and with a wide range of hardware and software features such as: LTE Cat M1, NB-IoT, SMS control, Firewall, open VPN, IPSec, RMS - users can be ensured that data can be reached securely and safely. Without this backward compatibility to EGPRS (2G) networks, users can upgrade already working devices to ensure that after the 2G network is switched off, your equipment will be accessible with the support of LTE Cat M1, NB-IoT.
