Antenna supply
(Factory setting: +5V for active antenna)
Active GPS antennas require a supply to drive the antenna. Typical standard
supply voltages are +5V and +12V. Note that in case you use a passive antenna
the supply selection jumper must be removed. Driving a passive antenna may
cause permanent damage to the antenna.
