Product information

Description

TRB255 is an industrial gateway designed to connect legacy and modern equipment in one system. It provides multiple I/O, serial and Ethernet ports and an integrated LPWAN modem that supports LTE Cat M1, NB‑IoT and backward compatibility with EGPRS (2G). The gateway supports IPv4/IPv6, TCP/UDP and common management protocols such as SNMP, and offers authentication options including pre‑shared keys and digital certificates for secure communication.

Advantages

The Teltonika TRB255000000 combines serial (RS‑232/RS‑485) and Ethernet interfaces with cellular LPWAN connectivity to extend the lifetime of legacy industrial devices while enabling modern IoT deployments. Its support for both LTE Cat M1 and NB‑IoT alongside 2G fallback ensures wide network availability. Standard networking features and secure authentication methods simplify integration and remote management.

Suitable for

Upgrading legacy industrial equipment to IP-based networks
Remote monitoring and control of industrial sites
IoT deployments requiring low-power wide-area cellular connectivity (LTE Cat M1, NB‑IoT)
Integration of serial devices (RS‑232/RS‑485) into Ethernet or cellular networks

Key specifications

Model: Gateway Teltonika TRB255000000 (MPN: W125727570)
Cellular: LTE Cat M1, NB‑IoT, EGPRS (2G) fallback
Ethernet: 10/100 Mbit/s
Serial interfaces: RS‑232, RS‑485
Networking: IPv4, IPv6, TCP, UDP; SNMP for management
Authentication: pre‑shared keys, digital certificates

How to use

Install the TRB255 in a suitable industrial enclosure or DIN‑rail mount location with access to required serial and Ethernet connections. Configure network parameters (IP, APN for cellular) via the device management interface, set authentication credentials or certificates, and map serial ports to the desired networking protocols. Use SNMP or the built‑in management tools for remote monitoring and firmware updates.

Usage recommendations

For reliable operation, ensure appropriate cellular coverage for LTE Cat M1 or NB‑IoT in your area and keep device firmware up to date. When integrating legacy serial devices, verify serial settings (baud rate, parity, stop bits) match the connected equipment and secure network access with certificates or pre‑shared keys.
