Components and Operation
2.1
Components in the Ground (Transponders)
Transponders type HG 71325 (by Götting KG) are applied as reference markers within
the ground. The system is compatible to all transponders of type HG 713XX used so
far (depending on the installed version of the reading antenna).
By using the switchable transponder HG 71370 a simple point- to- point connection in
addition to the positioning is feasible. The transponder, e.g. installed within the ground,
signals an approaching vehicle to the system. Thus the system is able to transfer a
message to the vehicle by selecting one of 4 codes to choose from. Furthermore tran-
sponder version HG 71370-W is able to change the positioning mode.
The transponder code provides 16 Bit serially or parallel.
2.2
Identifying Antenna HG 71451-A (Profibus)
The antenna system is in a 53 x 31 x 156.5 mm casing (polycarbonate). The antenna
is connected by 5-pole cables. The terminal connector is a M12 circular connector
(see Figure 4). As an accessory an elbow jack with different cable lengths is available
(standard 2 m).
