Teltonika TRM200 Industrial LTE Cat-4 USB Modem

The TRM200 is a plug-and-play USB modem compatible with Windows (using built-in or downloadable drivers), Linux (typically using CDC-ACM or MBIM drivers), and Android systems. For Linux, you may need to install usb-modeswitch and wvdial or ModemManager packages to establish a PPP connection. The device presents as a standard serial COM port or network interface once powered and recognized by the host system.

The modem features an external SMA female antenna connector. Unscrew the protective cap, then screw on the included swivel antenna or any standard SMA male antenna with 50-ohm impedance. For optimal performance in weak signal areas, use a high-gain directional antenna. Ensure the antenna is properly seated and the connection is tight to prevent signal loss and potential damage to the RF front-end.

The TRM200 is powered exclusively via its micro USB port, requiring a stable 5V DC supply. The included micro USB cable can be connected to a USB port on your industrial PC, a powered USB hub, or a 5V wall adapter. Ensure the power source can provide sufficient current (typically 500mA) for peak transmission loads. Avoid using long or low-quality USB cables that may cause voltage drop and instability.

Yes, but not directly. The TRM200 provides a USB network interface. To connect serial equipment, you need an additional USB-to-serial converter (e.g., FTDI chip) between the modem's host system and your serial device. Alternatively, use a dedicated serial-to-LTE gateway. On the host (e.g., a Raspberry Pi or industrial PC), software can bridge the serial data from the converter to the cellular network connection provided by the TRM200.
