Introduction – Chapter 2
2Introduction
The described antennas are especially suited for outdoor applications, as the elec-
tronic units are sealed within the antenna cases. All important settings, adjustable
values and software updates can be effected via a serial interface.
Unlike Transponder Positioning System S_I13933 (128 kHz operating frequency),
Transponder Positioning Antenna HG G-98780-A is operating at 13.56 MHz. This en-
sures sufficient frequency separation to interference sources such as, e.g., drives,
power converters and switching power supply.
Both systems supply a similarly structured output format in which additional system
information 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/ accessibility of the transponders and antennas. This system description
applies to devices with the firmware 98780B2 version 1.06 and higher.
2.1 Accessories
The following accessories are available for the one-dimensional Transponder Posi-
tioning Reader HG G-98780-A:
Figure 1 Components
1. Transponder reader with preamplifier and interpreter HG 98780-A with different
interfaces (see Table 2 on page 8)
2. Transponder HG 70661 (on the pavement)
3. Optional interface HG 06150-A serial/parallel converter
4. Optional desktop reading and programming unit HG 81830VA (not shown in
picture)
2.2 Functional Description
As the antenna passes over the transponder, it energizes the latter with an energy
field of 13.56 MHz. The transponder returns its code through frequency modulation
to the antenna. An additional coil generates the positioning pulse. The interpreter
which is integrated within the antenna decodes the transponder code.

8Chapter 2 – Introduction
Furthermore several antenna parameters, e. g. current consumption and supply volt-
age, are measured and, if desired, added to the serial output protocol.
The serial signal is made available via potentially separated RS 422 or RS 232 inter-
faces. In addition, the positioning pulse is dc-insulated. Furthermore, CAN Bus or
Profibus interfaces are provided optionally. The following variants are available, they
can be distinguished by the second to last character of the product number, e.g.
HG G-98780ZA.
As an option, the serial signal can be converted into a 16 bit parallel output signal
(24 Volts switched) for the code within an external interface device. This interface
device is suited for mounting rail (top-hat rail) installation and should be installed in
a place protected from any environmental influences (see section 5.3 on page 26).
2.3 Positioning Pulse
For the generation of the positioning pulse, it is necessary that the following precon-
ditions are met:
The reception voltage S (refer to Table 20 on page 30) must exceed the set
threshold for Level for Positioning (refer to section 6.2.2.2 on page 31).
A transponder code must be decoded without error.
The measured voltage X must fall below a certain threshold (refer to Table 20
on page 30).
If the above listed preconditions are met, a positioning pulse with changeable dura-
tion is generated. For the generation of a new positioning pulse it is essential that the
reception voltage S has fallen below the threshold set for Threshold for Deco-
ding (refer to section 6.2.2.2 on page 31) first.
Thus only one pulse per transponder crossing is possible. Therefore, if a vehicle/
crane stops above the transponder after the positioning pulse was generated and
then changes its direction of travel, no renewed positioning pulse is generated
during the center crossing!

Introduction – Chapter 2
Positioning Accuracy
As the field compensation for the corresponding measuring coil is not infinitely
sharp and is also depending on the reading height (refer to Appendix, Section 10.1
on page 43), the positioning pulse is generated at different but reproducible loca-
tions, depending on the direction of travel. Since the antenna is not aware of its di-
rection of travel, but depends on the physical effect of the field strength, only the ve-
hicle/crane control can carry out the direction-depending compensation. The
appendix, section 10.2 on page 45 shows the locations of the positioning pulse re-
lated to the X and Y coordinates and the reading height.

3.1 Transponders
3.1.1 Dimensions and Specifications
The maximum reading distance for all transponders can only be achieved when the
minimum distance to metal surfaces is maintained. It is recommended to maintain
the minimum distances within the metal-free area (Figure 2). The impact on posi-
tioning accuracy and range also depends on the size and distance of metal parts.
Figure 2 Minimum iron-free area around Puck Transponder HG 70661
As rule of thumb it can be said that if the metal-free area behind the transponder has
to be at least of the same range as the reading distance between transponder and
antenna. The reception of the transponder signal will be largely unattenuated (also
refer to Table 25 on page 47). It is essential, that the transponder does not dip into
the meshs/loops of steel reinforcement grids. Single metal rods, on the other
hand, hardly have any influence on the performance.
3.1.2 Mounting Instructions
The Transponders may be mounted on even ground using a metal screw and a
washer. The maximum fastening torque is not allowed to exceed 4 Nm. The diame-
ter of the metal washer should not be max. 18 mm. For further information please
refer to the transponder data-sheet HG G-70661.

Mounting – Chapter 3
3.2 Antenna HG 98780-A
Figure 3 Mounting the antenna
The casing of the antenna has bore holes for 4 screws (also refer to Figure 4 below).
We recommend the usage of M6 hexagon socket screws. The length of the screws
depends on where the antenna is to be mounted. Please make sure that in the direc-
tion of travel there is enough free space for the connections. Depending on the vari-
ant up to 140 mm are needed (the picture above shows the ZA/WA variants).

12 Chapter 3 – Mounting
In order to prevent any adverse effects on the system:
The space above and around the antenna should be metal-free. YOu can find
more information in the sections 10.3 on page 47, 10.4 on page 48 and 10.5 on
page 49.
Do not operate the reading antenna while the reading side is located directly
above a metal surface, as this would mistune the antenna severely in such a
way that the power consumption of the output stage would increase consider-
ably.
Perfect transponder readings are only guaranteed if the transponders are placed
within max. ±4 cm tolerance from the center line of the antenna! Outside these
limits, the transponder readings become less reliable due to decreasing signal
levels.
Whenever the antenna is operated at temperatures below 0oC, it is necessary to use
the integrated heater! As the warm-up time with heater at -20oC surrounding tem-
perature is approx. 1 hour, the heater should be connected to a stand-by power sup-
ply.
3.3 Interface HG 06150-A (optional)
The mounting of the optional interface is explained in the data sheet that you can
download from:

Installation / Commissioning – Chapter 4
4Installation / Commissioning
Check the operating voltage before connecting! The cable should not lie directly be-
side power supply cables.
Connect all necessary cables. For the next commissioning steps, connect a laptop
with the serial interface of the antenna. Antenna variants with RS422 interface
(HG 98780ZA/XA) require an appropriate interface converter. This interface convert-
er is not included in the scope of supply of this system. For further information,
please refer to the introduction in chapter 6 on page 27. Then start the monitor pro-
gram as described in section 6.2 on page 28.
Default values: In default the system uses the values of the file 1 (Mon3964r.txt;
as listed in part 6.2.1 on page 28) with 9,600 Baud. Please keep in mind that another
user could have changed these values.
1. Move a transponder into reception range.
The voltage S should increase significantly. The code should be detected imme-
diately and the number of readings has to be continuously counted up to
65535. When moving the transponder in driving direction over the center axis
of the antenna, a positioning pulse should be generated.
2. For setting the decoding thresholds (refer to section 6.2.2.2 „(T)ime & Code“ auf
Seite 31) it is useful, to record a complete test run along the transponder track.
Antennas HG G-98780ZA and HG G-98780WA offer for this function the use
of the serial interface (section 6.2.2.6 „CS(V)“ auf Seite 36) or the CAN Bus Mes-
sage Object 3 (section 5.2.6.4.4 on page 24 or 6.2.2.4 „C(A)N Parameters“ auf
Seite 34).
Antennas HG G-98780YA and HG G-98780XA offer for the same function
the serial interface (refer to section 6.2.2.6 on page 36) or the Profibus interface
(refer to section 6.2.2.5 on page 35). When using the Profibus interface, the nec-
essary parameters from the 16 byte data block are System Status, Code and
U-Summe.
Provided that the test run did not reveal any problems, changed parameters may be
saved and the monitor program may be terminated. Changing certain parameters re-
quires a complete system reset (switching the antenna off and on again), as de-
scribed in the corresponding section for the monitor program (section 6.2). This pro-
cedure ensures that the system is commissioned correctly.

RS422, power supply) are being used. The integrated LED is lit for the Profibus status
Data exchange.
5.2.3.2 Pin Allocations X1/X2/X3
This Profibus variant of the antenna offers up to two identical cable tails X1/X2 for
Profibus connections depending on whether a terminating resistor is included.

In addition there is a cable tail X3 for the power connection and the serial interface.
5.2.4 Positioning Pulse
The digital positioning output indicates the crossing of the center line of the antenna
in direction of travel (x direction). Its duration is adjustable within a millisecond pat-
tern.
Both positioning connections are separately and not internally connected to +24 V
or GND, as a strict voltaic separation is essential for some of the systems. For safety
reasons, a 20 mA current limitation has been implemented in the antenna for these
outputs. In case a 24 V output is required, contact No. 9 may be connected to +24 V
and contact No. 10 may be connected to GND via a 1 KOhm resistor.

5.2.5 Switch-on Characteristics
Once the supply voltage has been applied, the antenna requires 10 s until it reacts
to data input, or outputs data protocols. During these 10 s, a software download may
be started (also refer to section 5.2.7 on page 26).

5.2.6 Interfaces
5.2.6.1 Serial (RS 422 / RS 232)
The serial output may be configured in several ways. The transmission rate is adjust-
able between 9600 and 19200 Baud, the output protocol may be chosen as “trans-
parent“ or “3964R“. 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. The crossing of the an-
tenna´s center axis in direction of travel, is shown by the digital positioning output.
Its transmission time is adjustable in blocks of milliseconds. In addition, it may be re-
duced to one impulse per crossing.
5.2.6.1.1 List of system data to be output
A telegram consists of max. 15 bytes. The minimum update rate at 9600 Baud is
then calculated as follows
Figure 10 Formula: minimum update rate
As the transmission is binary, it is possible - when using the 3964R procedure - that
further (DLE) characters are added by this procedure. All multiple-byte variables are
output either with the highest byte or the lowest byte first (adjustable)!
The 8 bit check character is only output when using the transparent protocol. It then
includes the start character. The check character (transparent protocol), cannot be
removed from the data block. It is a matter of configuration, whether data telegrams
are output permanently according to the set update rate or only during the period,
when a transponder is within the field.
