Field interfaces
- RS232 / RS485: Serial buses
- I/O: 16-pin I/O connector (per official documentation)
INDUSTRIAL GATEWAY
Teltonika TRB246
Teltonika TRB246 is a current industrial gateway in the GermanSTS Industrial Networking & IoT catalogue. GermanSTS evaluates TRB246 for projects where 4G LTE and documented Teltonika specifications matter — Teltonika Networks is the manufacturer.
Dual-SIM LTE gateway combining Ethernet, RS232, RS485 and digital I/O — for M2M sites that need several field interfaces on one RutOS cellular uplink.
GermanSTS compares TRB246 with TRB245 and TRB247 when I/O count, serial mix and cellular category differ.

Where TRB246 fits
Dual-SIM LTE gateway combining Ethernet, RS232, RS485 and digital I/O — for M2M sites that need several field interfaces on one RutOS cellular uplink.
What to verify before selecting TRB246
- Inventory which serial buses (RS232 vs RS485) and I/O lines must be terminated on the gateway.
- Confirm dual-SIM policy and antenna layout for the installation environment.
- Validate Ethernet port role (LAN downstream vs diagnostics) on the official interface map.
- Check protocol support on the target firmware before committing integration design.
