In addition there is a cable tail X3 for the power connection and the serial interface.
5.2.4 Positioning Pulse
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.
Both positioning connections are separately and not internally connected to +24 V
or GND, as a strict voltaic separation is essential for some of the systems. For safety
reasons, a 20 mA current limitation has been implemented in the antenna for these
outputs. In case a 24 V output is required, contact No. 9 may be connected to +24 V
and contact No. 10 may be connected to GND via a 1 KOhm resistor.

5.2.5 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 5.2.7 on page 26).
