16-pin Antenna connection socket
The antenna is equipped with a 16 pin connection socket. The pin allocation is as fol-
lows:
The two positioning pins are lead through separately and internally neither connected
to +24 V nor to GND, as in some applications it is essential that strict potential sepa-
ration is maintained. For security reasons, a 20 mA current limitation for these outputs
is implemented within the Antenna. Thus if, e. g., a 24 V voltage output is required it is
possible to connect pin 9 with +24 V and pin 10 via a 1 KOhm resistance with GND.

Turn-on characteristics
Upon applying the operating voltage, the antenna requires 10 seconds startup time.
During this period, it is possible to start a firmware update (also refer to section 5.4 on
page 44).
