• Sites without reliable fixed broadband or as a temporary link during outages

Key specifications

• Cellular technology: LTE (4G) with backward compatibility to 3G/2G where supported
• Form factor: compact industrial housing suitable for DIN-rail or small-space installation
• Interfaces: standard data interfaces for integration with routers and equipment (wired connectivity options)
• Power: industrial power input range compatible with remote and machine environments
• Operating conditions: designed for extended operation in industrial temperature and humidity ranges
• Management: remote configuration and monitoring capabilities for network administrators

How to use

Install the TELTONIKA TRM142 in a protected enclosure or on a DIN rail near the device requiring cellular connectivity. Connect the modem to a suitable power source and attach the required antennas. Integrate the modem with the target equipment via the provided data interface and configure APN and connection parameters using the vendor’s configuration tools or web interface. Verify signal strength and test data sessions to confirm stable connectivity and expected throughput.

Recommendations

Place antennas where they receive minimal obstructions to improve signal quality; keep the modem firmware updated and configure automatic reconnection and watchdog features where available to ensure continuous service. For critical applications, test the modem in the intended location before final installation and consider using external antennas or mounting adjustments to optimize reception.
