Introduction
The described antenna is especially suited for vehicles in outdoor areas, as the elec-
tronic units are sealed within the antenna case. It is possible to adjust all important set-
tings and values after manufacturingoftware as well as proceeding software updates
via a serial interface.
The antenna supplies a structured output format in which additional system in-forma-
tion can be configured by the user. This information can, for example, be saved in a
visualization system and enables statements about the condition and availability/ ac-
cessibility of the transponders and antennas. This device description applies to de-
vices with the firmware 71895C2 beginning from version 1.14.
1.1
System Components
In addition to the positioning and identification antenna the following components are
available:

System Components
1.
Transceiver antenna with preamplifier and interpreter HG 98760ZC (interface
RS422 and CAN) or HG 98760YC (interface RS232 and Profibus)
2.
Transponder trovan™ ID200/250/800/800 (placed in the track)
3.
Optional interface HG 06150ZA RS422 for parallel output
4.
Optional programming device for trovan™ transponder HG 81830YA (not shown
in picture)
1.2
Function
As the antenna passes over the transponder, it energizes the latter with an energy field
of 128 kHz. So the transponder transmits his code at half of this frequency. The tran-
sponder position in relation to the antenna surface is measured by a coil with orienta-
tion in direction of travel. The interpreter which is integrated within the antenna
decodes the transponder code.
