6Chapter 2 – Introduction
2Introduction
The herein described system is especially suited for indoor areas. The electronic units are
not sealed within the antenna cases, but varnished. Therefore it is possible to effect all im-
portant settings and adjustable values after manufacturing. This leads to fair priced sys-
tems. Software updates can be effected using a serial interface.
The interpreter HG G-71912-A supplies the transponder code as a serial signal or parallel
signal as well as a midpoint crossover pulse when crossing over a transponder, which is re-
producible very exactly.
The transponders used in this system are HW DEV00095/HW DEV00098 or HG G-71325XA
(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 distances).
This manual refers to equipment with software version 1.08.
2.1 Interpreter Variants
The interpreter is available in three different variants:
2.2 System Components

7Introduction – Chapter 2
2.3 Function
As the antenna passes over the transponder, it energizes the latter with an energy field of
128 kHz. The transponder returns its code at half of this frequency.
The transponder position in relation to the antenna surface is measured by a coil with ori-
entation in direction of travel. The interpreter decodes the transponder code. Each crossing
of the coordinate axis in driving direction generates a positioning pulse with an adjustable
duration.
The serial output signal is a non-voltaic RS 232. Alternatively it is possible to use a CAN bus.
The positioning pulse is not galvanically separated but available as a +24 V (20 mA) opera-
tional voltage switched output. Optional a 15 bit parallel output for the code (24 Volt
switched, non current limiting) can be effected.
Transponders may also be programmed. Therefore the transponder has to be located within
the antenna field at least 30 ms after starting the programming cycle.
2.3.1 Surveillance Of The Output Stage
The output stage is surveilled concerning the following errors:
– capacity of oscillatory circuit, short circuit, idling, detuning
– oscillator breakdown 128 kHz, frequency deviation
– short-circuit transmitting conductor, idling
– power transistor is defect
By this surveillance with a certain probability the function can be detected. Defective con-
tacts or ripped-off cables between interpreter and antenna are checked constantly. A non-
authorized change in parameters leads to the setting of a bit in the system status (see also
Tabelle 7 auf Seite 19).
ATTENTION!
Also the crossing of a massive steel plate may possibly trigger the surveillance!
After programming the transponder an error bit is set, as the surveillance circuit reacts to
the altitude modulation (AM) of the output stage, which is created for programming the
transponder. The error bit is deleted by a successful reference transponder test.
2.3.2 Switchable reference transponder in the antenna
It is recommended that in front of each starting and each change of driving direction a ref-
erence transponder test is proceeded via a serial command. That way, the complete func-
tion of the antenna and of the interpreter is checked cyclically. If the test has been success-
ful, a positioning pulse is output.
2.3.3 Software Update (RS232)
Until up to 10 seconds after turning on the device, an update can be started by using a spe-
cial PC program without opening the system monitor. Additionally, there is a submenu for
the software update in the system monitor (see also chapter 6.3 on page 43).

8Chapter 3 – Mounting
3Mounting
3.1 Transponder
The maximum reading distance for all transponders can only be achieved when the mini-
mum distance to metal surfaces is maintained. There are some transponder types especial-
ly optimized for the mounting directly on metal. To clarify the configuration, it is essential to
carry out tests!
As mentioned above, it is recommendable to maintain the minimum distances within the
metal-free area (Figure 2). The impact on positioning accuracy and range also depends on
the size and distance of metal parts.
Figure 2 Minimum spacings around the transponders (on-track mounting) and the antenna HG G-
98767ZA
Alternatively the transponder can be mounted level with the road. In this case, the antenna
has to be placed into an accordingly lower position to ensure the nominal reading distance.
Note
Electric power lines (for example for charging points) may not be passed in this area, as the
reading of the code will be complicated or the code will be falsified by pulses which may
occur.

11Commissioning – Chapter 4
4Commissioning
Note
Check the operating voltage before connecting! Although the RS 232 interface reacts large-
ly insensitive to interferences, the cable should not be located directly beside power supply
cables.
Connect all necessary cables. For the next commissioning steps connect a laptop with the
antenna. Then start the monitor program as described in section 6.2 on page 31.
1. Move the transponder below the antenna
In the status line the voltage S has to rise significantly. The code has to be detected
immediately and the number of readings has to be counted up to 255 constantly.
When the transponder crosses the center axis of the antenna in driving direction, a
positioning pulse has to be generated.
2. Remove the transponder from below the antenna
If there is no transponder in the field, the voltage S has to fall to extremely small val-
ues. The code display and an possible display of the number of readings remain. If
that is not the case, interferences in a frequency range of 64 kHz are induced.If no
errors occurred, the monitor program can be closed. Remember to save possibly
altered values. After changing certain parameters, a system reset is required (turn-
ing off and on the antenna). This procedure is explained in the corresponding chapter
of the monitor program (see chapter 6.2 „System Monitor“ on page 31).
3. Now proceed an one-time reference transponder setup by transmitting the corre-
sponding serial command (see Tabelle 5.3.2.1.2 auf Seite 20) or by using the corre-
sponding submenu in the monitor program (see Tabelle 6.2.1 auf Seite 31).
Note
This command may only be carried out once during the commissioning, as otherwise
changes in the accuracy of the antenna remain undiscovered, as they are included in the
reference values each time a setup of the reference transponders is proceeded!
The new reference values, found during the reference transponder setup (sum. and differ-
ence voltage), are saved automatically to the parameter E2PROM when applying the serial
command.
4. Now, it is recommended to protocol a complete drive. Depending on the antenna ver-
sion there are different possibilities:
Parallel interface (in the interpreter version HG G-71912YA)
Here, a logging is possible via a serial interface (see chapter 6.2.2.9 on page 41).
CAN-Bus (in the interpreter version HG G-71912ZA, XA)
Here, a logging is possible via a serial interface (see chapter 6.2.2.9 on page 41).

12 Chapter 4 – Commissioning
In the following diagrams examples for registered data are shown:
Figure 6 Diagram: commissioning protocol / low interference; sum voltage over track
In the diagram the sum voltage over the track is shown. The noise (interference) level is lo-
cated at 50 samples, the signal at 950. The decoding of the transponder is faultless, as also
shown in the following picture.
Figure 7 Diagram: commissioning protocol / undisturbed decoding of the transponder
When crossing a transponder the sum voltage rises. After exceeding the Threshold for De-
coding the bit TRANS_IN_FIELD is set. After 4 x 8 ms ( = four data points) is transponder
code is decoded. The duration depends on the settings made under Number of Equal Codes
in the submenu Time & Code. In this example 2is chosen, that means that the input code
is compared with the two precedent codes.

Undisturbed decoding of the transponder
Device Description HG G-71912-A | English, Revision 03 | Date: 28.03.2018
13Commissioning – Chapter 4
After crossing the center of the antenna the POSI pulse is triggered. Its duration is termi-
nable. The bits TRANS_IN_FIELD and CODE_OK are deleted, as soon as the sum voltage
falls below the Threshold for Decoding. In this example a reserve from 6 x 8 ms for trigger-
ing the POSI-Puls is left. The crossing velocity is approx. 0.87 m/s (140 mm length of anten-
na / 20 x 8 ms).
In the following protocols the impacts of a high interference level can be seen.
Figure 8 Diagram: commissioning protocol / high interference; sum voltage over track
The interference level reaches up to 300 samples. At transponder 207 the noise is due to a
charging station so high, that it even influences the transponder signal. As an impact it takes
9x 8 ms until the transponder 203 is decoded (see Figure 9 on page 14). This is sufficient
for a slow crossing velocity of 0.5 m/s (140 mm / 33 x 8 ms) to generate a POSI pulse, in
contrast a velocity of 1 m/s is to high, this transponder cannot be crossed with such a ve-
locity.
High interferece level

14 Chapter 4 – Commissioning
Figure 9 Diagram: commissioning protocol / disturbed decoding (but still functional)
In the following diagram it is shown how a false set Threshold for Decoding or Threshold for
Positioning can cause erroneous POSI pulses.
Figure 10 Diagram: commissioning protocol/POSI-Pulse triggered by noise & too high Thresh.
In this example the thresholds are set to 100 samples. The bit TRANS_IN_FIELD is set con-
stantly. After a successful decoding a correct POSI pulse is triggered. As the software does
not know, that the antenna field is left then, each further zero crossing of the difference sum
generates a new POSI pulse.
Disturbed decoding (function still available)

5Components and Operation
5.1 Underground components
Transponders of the type HW DEV00095/HW DEV00098 or HG G-71325XA may be used as
reference points. All described RW transponders can be programmed using the reading an-
tennas or an optional programming device of the type HG G-81830YA.
Range and accuracy of the system are influenced by:
– any large metal pieces (sheets) on the ground
– proximity of any floor reinforcement (see chapter 3 „Mounting“ on page 8, section 3.1
„Transponder“ on page 8)
– Inductive loops, as they are created e.g. by steel building mats have a great influence.
Individual metal poles have little effect. Those may be partly within the metal-free
area (see Figure 2 on page 8).
– Cable with pulsed currents with spectral parts between 64 kHz ±4 kHz
– The following environmental conditions have no effect on the system:
–Snow,ice,water
– Oil, tar, earth, dirt, etc.
Code structure
The code length is 20 bit of useful data. The system decodes and outputs the entire code
string; when using the parallel interface only the 15 lowest bits are output. The data protec-
tion within the trovan™ transponders is done by line (of 3 bit each) and column parity. To
achieve a better data protection, it is therefore recommended to implement an additional
code check when using RW transponders. The transmission duration for one complete tele-
gram is 8 ms for both types.

5.2 Antenna
In general, different antennas which are all described within their own device descriptions
can be used with this interpreter (the right device description has been delivered with the
system), but at the moment, there is only one matching type:
– HG 98767ZA - this antenna has an effective antenna surface of 130 x 180 mm and
allows a crossing velocity of 2 m/s (with positioning pulse)
5.3 Interpreter HG G-71912-A
Figure 11 Interpreter HG 71912-A (shown: version HG 71912ZA with serial interface)
The electronics of the interpreter are cased in a aluminium housing (206 x 87 x 48 mm incl.
fastenings clips). The antenna can be connected via a 9 pin jack. The interpreter can also be
connected to the processor of the device via a 8 pin plug. The connections can be found on
the front end of the device. Concerning the interfaces and cables the following variants are
available:

There are five control LEDs.
5.3.2 Interfaces
5.3.2.1 RS 232
The serial output may be configured in several ways. The transmission rate is adjustable be-
tween 9600 and 19200 Baud, the output protocol may be chosen as either "transparent" or
"3964 R" (see also sections B on page 48 and C on page 49). Apart from that, the content
of the telegrams is configurable, as the user may choose from a list of parameters. Serial
commands are used for activating a system monitor.
5.3.2.1.1 List of System Data that may be Output
A telegram of the serial RS 232 output consists of max. 13 bytes.
The minimum update rate at 9.6 KB is then calculated as follows:
Figure 12 Formula: Minimum update rate
As the transmission is binary, it is possible – when using the 3964R procedure – to add fur-
ther (DLE) characters by this procedure.
All multiple byte variables are output either with the highest byte or the lowest byte first (ad-
justable)! The 8 bit check sum is only output when using the transparent protocol. It then
includes the start character. The start character, as well as the check sum (transparent pro-
tocol) cannot be removed from the data block.

rameters and at last the check sum (XOR relation of all bytes with starting sign). When
choosing the procedure "transparent" (see also appendix, see page C on page 49) also a
start sign has to be sent.
Four commands are defined:
Note
No. 1:The monitor mode should not be used in normal mode (for example from a PLC) as
the following data output will not be realized in transparent or 3964R mode. It is suited for
the VT52 terminal, which can be used to alter parameters.
Note
No. 4: The comparative values (sum and difference voltage) are saved automatically in the
parameter E²PROM. This command should only be proceeded once during commissioning,
as otherwise changes in the exactness of the antenna may not be noticed as at every setup
of the reference transponder test the reference values are considered!
