Hardware
3.1 Transponder
The Götting transponders listed in Table 3 on page 10 are used as reference marks
in the ground. The transponder code consists of 16 bits.
3.2 Transponder Antenna (Variants)
3.2.1 Applies to all variants
The antenna system is located in a 156.5 x 31 x 53 mm (L x D x H) housing made
out of PC (polycarbonate). Depending on the variant, the height including connec
-
tors is max. 70 mm.
3.2.1.1 Switch-on Behavior
After applying the operating voltage, the positioning output is active for the duration
of the reset (approx. 500 ms). To check their function, all LEDs are switched on for
500 ms, respectively. After approx. 2 s the device is ready for operation.
3.2.1.2 Code Output
The code transmitted by the transponder consists of a sequence of 24 bits in which
16 bits are coded. These are output serially or – with the optional serial/parallel in
-
terface (see below) – parallel. Transponders can also be programmed via the anten
-
na and the telegrams of the serial interface (see chapter 10 on page 61).
3.2.1.3 PosiPulse
The transponder antenna provides an output for the PosiPulse via ST 1 in all variants.
The position impulse is triggered at center crossing of the antenna. Its duration is
100 ms. When activated, 24 V with a current limitation of 20 mA are switched on the
corresponding output (no potential separation). For the sequence of a transponder
crossing and the triggering of the PosiPulse see chapter 2.7.3 „Signals and Timing“
on page 15.
If, for example, a 24 V voltage output is desired, contact 2 can be connected to GND
via a resistor of 1 KOhm, as shown in the following picture.
