The digital positioning output indicates the crossing of the center line of the antenna
in direction of travel (X- direction). Its duration is adjustable within a millisecond pat-
tern. In addition it can be limited to one pulse per crossing.
Both connecters for positioning are not internally connected with +24V or GND as in
some systems a strict isolation of potentials has to be kept. Due to security require-
ments the current in these outputs is limited to 20mA. If e.g. a 24 V output is needed,
contact number 9 has to be connected with +24V and contact number 10 has to be
connected with GND using a resistor of 1 KOhm.

Switch-on characteristics
Once the supply voltage has been applied, the antenna requires 10 s until it reacts to
data input, or outputs data protocols. During these 10 s, a software download may be
started (also refer to section 5.2.2.4 on page 33). A further 16 seconds are necessary,
in case the automatic transmitter tuning function is activated
