Introduction
The described antenna is especially suited for vehicles in indoor areas. The electron
-
ic units are not sealed within the antenna cases, but varnished. Therefore it is possi
-
ble that all important settings and adjustable values are effected after manufactur
-
ing. This leads to fair priced systems. Software updates can be effected via a serial
interface.
The
one-dimensional antenna HG G-71910-C
supplies the transponder code as
a parallel signal as well as a midpoint crossover pulse, generated by an exactly mea
-
surable and reproducible phase alteration.
The transponders used in this system are HG G-71325 resp. HW DEV00095 (read /
write). These transponders are fair priced and especially suited for the applications
of this system (track guided or rail- mounted vehicles with fairly small reading dis
-
tances). This manual refers to antennas with software version 1.43 or higher.
