The DC input for the terminal is designed for both 24 V DC and 12 V DC power supply. EXPLORER 325 antenna The EXPLORER 325 antenna is a mechanical tracking antenna, consisting of a 2-axis stabilized antenna with RF-unit, antenna control unit and GPS antenna. The antenna is dedicated to the Inmarsat BGAN (Broadband Global Area Network) system and is designed for roof mounting on a vehicle.
Besides the normal functions of an IP handset, the Thrane IP handset also provides a user interface for the EXPLORER 325 system. The IP handset connects to the LAN interface of the terminal, and is power supplied with Power over Ethernet (PoE) through the LAN interface.
