Beam - TranSAT RST620 Terminal


The Beam TranSAT Fixed Satellite Telephone provides a complete hands-free voice and telephone for a wide range of mobile and fixed site applications where easy access to reliable voice and data communications is required.

The terminal provides a compact fully functioned user handset and supports both hands-free and privacy modes of operation, automatically switching between either mode with the handset in or out of the cradle. The system can also be used as a permanent non hands-free solution simply by not connecting the microphone. The loud ring indication through the speaker system makes it an ideal installation in a noisy environment.

The RST620 is equipped with an RS232 serial data port to access Iridium data services.

There are added features that enable the unit to be integrated into communications systems via the line in/out, serial data connectivity, radio mute, horn alert and a robust inbuilt 10 – 32 VDC power supply.
