Postal approval
The postal approval can only be granted for final products,
not just for components like the HTRM800. But this reader
module is designed in a way that it is possible to get the
postal approval for a system including the HTRM800.
Electromagnetic emissions comply with the guidelines in
FTZ 17 TR 2100, ETS 300 330 and ETS 300 683.
Electromagnetic immunity complies with the guidelines in
ETS 300 683.
The following configuration is in compliance with the
European telecommunication standards:
Reader module HTRM800
Power supply according to the recommendations
(transformer type)
Antenna: 50
×
70 cm, number of turns N = 26 and
inductivity L = 1.2 mH.
A survey of the passed measurements is given in Table 1.

Operating security
The following mechanisms ensure the operation security
of the HITAG system:
Anticollission mode
Monitoring the supply voltage
Antenna rupture and short circuit.
7.5.1
A
NTICOLLISION MODE
Anticollision mode in long range applications permits you
to process several HITAG 1 transponders simultaneously.
Theoretically up to 2
32
HITAG 1 transponders can be
processed simultaneously. In practice this number is
limited, because of the mutual influence of the
transponders. They detune each other, if there are too
many too close to each other. In long range applications
using HITAG 2 transponders, only one transponder is
handled even if there are several transponders within the
communication field of the antenna. In this case either no
communication takes place or the ‘stronger’ or closer
transponder takes over.
By muting a selected transponder (HALT mode) another
transponder that is to be found in the communication field
of the antenna can be recognized.
7.5.2
M
ONITORING THE SUPPLY VOLTAGE
The supply voltage is controlled by a watch dog circuit
which triggers a system reset if the supply voltage of the
core module drops below 4.75 V or if the microcontroller
fails.
7.5.3
A
NTENNA RUPTURE AND ANTENNA SHORT
-
CIRCUIT
TheHTRM800doesnotgetpermanentlydamagedincase
of an antenna rupture or a brief antenna short-circuit. The
detection of detuned or broken antennas (antenna
malfunction) is possible.
