6.1.2 GNSS antenna connection
The GNSS antenna connection is supplied with a voltage of approx. 3.3 V and can supply active
antennas with a maximum current of 40 mA. The connection is short-circuit-proof and detects that an
antenna is present when the current is greater than approx. 2 mA.
Make sure that the unit is switched off during installation.
