Security

The TRB245 includes robust security protocols such as configurable firewalls, VLAN support, mobile quota control, blacklist/whitelist filtering, TACACS+, and RADIUS authentication. Attack prevention features mitigate risks from DDoS, port scans, and unauthorized access attempts.

VPN Capabilities

Comprehensive VPN support includes OpenVPN, IPsec, GRE, PPTP, L2TP, SSTP, WireGuard, Tinc, DMVPN, and ZeroTier, offering flexible encryption and tunneling solutions for secure remote connections.

Industrial Protocol Support

The TRB245 supports a variety of industrial communication protocols including BACnet (RS485/TCP), Modbus (RTU/TCP), OPC UA, DNP3, and DLMS/COSEM, ensuring seamless integration with diverse industrial equipment.

Data to Server and MQTT Gateway

Enables data transmission via HTTP(S), MQTT, Azure MQTT, and features a Modbus-MQTT gateway. It supports custom LUA scripting for advanced logic and data handling, and configurable API endpoints via Teltonika’s Web API.

Monitoring and Management

Multiple management interfaces are available including WebUI (HTTP/HTTPS), CLI, SMS, SNMP, TR-069, RMS, JSON-RPC, and SSH. The device supports firmware-over-the-air updates (FOTA), configuration backup, and custom profile management.

GNSS and Location Tracking

Equipped with GPS, GLONASS, Galileo, BeiDou, and QZSS, the TRB245 provides precise geolocation and geofencing support. Outputs include coordinates via WebUI, SMS, TAVL, RMS, and support for NMEA and NTRIP protocols.

Input / Output Interfaces

The TRB245 includes 3x configurable digital inputs, 3x digital outputs, and 1x analog input. The I/O juggler feature allows conditional logic and automated event notifications via email, SMS, or RMS.

Serial Communication

RS232 and RS485 interfaces support Modbus gateway, serial-over-IP, console access, and NTRIP client functions, enabling wide device compatibility.

Power and Physical Specifications
