Interfaces
9.1 PosiPulse
The digital positioning pulse at pin 2 of the POWER connector transmits the crossing
of the center of the antenna in the direction of movement. Its duration can be set in
millisecond increments. You can limit the positioning pulse to one pulse per cross
-
ing, see section 10.2.6 „(T)ime & Code“ on page 56.
The PosiPuls can be transmitted alternatively to the way described here in the status
of the serial or CAN telegram. In this case, however, the latency of the data output
period must be taken into account. Furthermore, a CAN telegram (without data con
-
tent) can also be triggered directly by the positioning pulse, see section 9.4.4 „CAN
Message Object – P-Identifier, Send Object“ on page 44.
The positioning pulse output is internally connected to +24 V (no potential separa
-
tion). For safety reasons, a 20 mA current limit is implemented in the antenna for this
output. If, for example, a 24 V voltage output is required, pin 2 can be connected to
GND via a resistor of 1 kOhm as shown in the following figure.

The content of the telegrams (serial and CAN) can be "frozen" for an adjustable num
-
ber of telegrams to the values at the time of the positioning pulse (see 10.2.5 „(S)erial
Output“ on page 52 and 10.2.8 „Basic C(A)N-Parameters“ on page 62.
9.2 Serial Interface (RS232)
The serial interface is used in the following way:
either as a data interface (as described here)
or as a service interface (see chapter 10 „Configuration of the System via the
Service Interface“ on page 48).
In the state as delivered, the serial interface is in
Monitor only
mode. You can then
use the serial interface via a computer as a service interface for configuration.
