Fig. 60. Satellite: Iridium
9.2.1.2 Installation (logger side)
The Iridium antenna must be installed in vertical position, with the cable entry facing
the ground. The antenna needs to have the greater open-sky visibility possible, with the
only interruption of the tower structure. We recommend the boom for the antenna to
be long enough, for instance 1,5m.
The Iridium modem needs to be connected to the Ext. Com RS-232 terminals 44 and 43.
The modem can be powered directly from the logger terminals 46 and 45.
