Teltonika TSM232 is the Iridium SATELLITE terminal with a backup battery. The full solution combines Teltonika TSM232 with Teltonika FM63XY, FMB630, or FMB640 connected via RS232. This solution allows transferring data to a server via the Iridium satellite network when other terrestrial networks are unavailable. High capacity internal Ni-MH battery ensures long autonomous working hours when the main power source is disconnected. Such a solution meets the demand for high-security logistics, marine transport, construction & mining transport, oil/gas industry, public safety, government/defense, and more.

Basic characteristics
