Introduction HG G-98760-C
English, Revision 06, Date: 14.12.2016 5
1 Introduction
The described antenna is especially suited for vehicles in outdoor areas, as the elec-
tronic units are sealed within the antenna case. It is possible to adjust all important set-
tings and values after manufacturingoftware as well as proceeding software updates
via a serial interface.
The antenna supplies a structured output format in which additional system in-forma-
tion 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/ ac-
cessibility of the transponders and antennas. This device description applies to de-
vices with the firmware 71895C2 beginning from version 1.14.
1.1 System Components
In addition to the positioning and identification antenna the following components are
available:
Figure 1 System Components
1. Transceiver antenna with preamplifier and interpreter HG 98760ZC (interface
RS422 and CAN) or HG 98760YC (interface RS232 and Profibus)
2. Transponder trovan™ ID200/250/800/800 (placed in the track)
3. Optional interface HG 06150ZA RS422 for parallel output
4. Optional programming device for trovan™ transponder HG 81830YA (not shown
in picture)
1.2 Function
As the antenna passes over the transponder, it energizes the latter with an energy field
of 128 kHz. So the transponder transmits his code at half of this frequency. The tran-
sponder position in relation to the antenna surface is measured by a coil with orienta-
tion in direction of travel. The interpreter which is integrated within the antenna
decodes the transponder code.

Further, different characteristics of the antenna, like for example current consumption
and supply voltage, can be measured and added to the output protocol.
The serial output signal is a non-isolated RS 232 or RS 422. The positioning pulse is
also galvanically isolated +24 V (20 mA) switched output. Alternatively it is possible to
use a CAN bus or a Profi Bus. The follwing table 1 gives on overview of the available
variants.
Optional a 16 bit parallel output for the code (24 Volt switched) can be effected. This
interface is suited for mounting bar installation and should be installed in a place pro-
tected from any environmental influences.
1.3 Positioning
To trigger a positioning impulse the following conditions have to be fulfilled:
-signal S (see Table 16 on page 29) has to exceed the set threshold Level for
Positioning (see 5.2.2.2 on page 30)
-the transponder code has to be decoded correctly
-measurement voltage X has to switch its algebraic sign
Then an impulse is created which can be varied in duration.

Mounting HG G-98760-C
English, Revision 06, Date: 14.12.2016 7
2Mounting
Inside the casing are four drill holes for four M5 screws.
ATTENTION! Make sure that the antenna is mounted correctly! Check the ori-
entation of the antenna thoroughly!
Figure 2 Mounting the antenna
In order to prevent any adverse effects on the system:
-The space above the antenna (at least 80 mm) should be kept free of any metal
parts. Make sure that there are comparatively large electrically conductive sys-
tems within this area.
-To guarantee a perfect operation of the transponder system, it is essential that
there are no interfering signals in the frequency range of 64 ± 4 kHz (e.g. pulse
engines etc.)!
-Make sure that the transponder track is located centered below the antenna (max.
tolerance ±5 cm). Outside this area the signal strength decreases quickly and
thus readings are unreliable.
NOTE! The heater has to be used if the antenna is operated at tempera-
tures below 0oC! As the heating period lasts about an hour at
-20oC it is recommended that the heating is connected to a
standby system.

3 Installation / Commissioning
NOTE! Check the operating voltage before connecting! Although the
RS 422 interface reacts largely insensitive to interferences, the
cable should not lie directly beside power supply cables.
Establish all required connections. For the next commissioning steps connect a laptop
with the antenna via a RS 422 to RS 232 interface (not in the scope of supply). Then
start the monitor program as described in section 5.2 on page 27.
Default values By default the system starts into the mode „Monitor only“ at 9600
baud. Keep in mind that another person might have changed
those settings!
1. Move a transponder under the antenna.
The voltage Sshould increase significantly in the status line. The code should
be detected immediately and the number of readings have to be counted up
continuously to 255. When moving the transponder in driving direction over the
center axis of the antenna, a positioning pulse should be generated.
2. Remove the transponder.
The voltage Sshould decrease to very small values if there is no transponder
within the field. The code display and the number of readings will be preserved.
If this is not the case, there are interferences in the frequency band of 64 kHz.
3. in case the antenna has been mounted directly on metal, it is necessary to re-
tune it accordingly. For setting the positioning and decoding thresholds (refer to
section 5.2.2.5 on page 35) it is useful, to record a complete test run along the
transponder track.
Antenna HG 98760ZC/WC makes this possible via the serial interface (see
5.2.2.6 on page 36) or the CAN Bus Message Object 4 (4.2.4.3.5 on page 22 or
5.2.2.5 on page 35).
Antenna HG 98760YC/XC offers for the same function via the serial interface
(refer to section 4.2.4.1 on page 17 ) or the Profibus interface (refer to section
4.2.5 on page 22). When using the Profibus interface, the necessary parameters
from the 16 byte data block are System Status, Code and U-Summe.
If no errors have occurred, exit the monitor program. Don’t forget to save the altered
values. If certain parameters have been changed, a system reset will be necessary
(switch off and reactivate then the antenna) as mentioned in the corresponding section
of the monitor program (section 5.2). Now the system has been put into operation
properly.

The following diagrams show examples for protocolled data:
Figure 3 Diagram: commissioning protocol / low interference; sum voltage over the
track
In the diagram the sum voltage over the track is shown. Noise (inference) is located at
50 sampels, the signal at 950. The decoding of the transponder has no problems, like
also shown in the next picture.

lems

Installation / Commissioning HG G-98760-C
English, Revision 06, Date: 14.12.2016 10
Whenever a transponder is crossed, initially the sum voltage will increase. Once the
Threshold for Decoding has been reached, the bit TRANS_IN_FIELD is being
set. It takes 4 x 8 ms (= 4 datapoints) for the transponder code to be decoded. The
duration depends on the setting of Number of Equal Codes in menu Time &
Code. In the given example, the value is = 2, i. e. the received code is compared to
two pre-ceding codes.
When crossing the center of the antenna, the POSI-Pulse is generated. The duration
of the POSI-Puls is adjustable. The bits TRANS_IN_FIELD and CODE_OK are delet-
ed as soon as the sum voltage falls below the set value for Threshold for Deco-
ding. In the given example, there was an additional period of 6 x 8 ms for the gener-
ation of the POSI-Pulse. The transponder crossing speed was approx. 1,9 m/s (300
mm length of active antenna area / (20 x 8 ms)).
The following diagrams illustrate the effects of high interference levels.
Figure 5 Diagram: Commissioning protocol / high interference level; shown is the
sum voltage over the distance travelled, indicated by different transponder
codes
The interference level reaches up to 300 samples. At transponder 207, the noise
reaches a level that even directly influences the transponder signal. As a result, it takes
9 x 8 ms until the transponder 203 has been decoded (refer to Figure 6 on page 11).
For the slow crossing speed of 1.1 m/s (300 mm / (33 x 8 ms)) 9 x 8 ms is still sufficient
for generating a POSI Pulse, but at a speed of 3 m/s it would no longer be possible
to decode this transponder.

The following diagram shows a case in which false POSI-Pulses may be generated
through wrongly set parameters for Threshold for Decoding and/or Threshold
for Positioning.

For this example, the thresholds are set to 100 samples. The bit TRANS_IN_FIELD is
permanently set. Following a successful transponder decoding, initially a correct
POSI-Pulse is generated. However, as the software does not realize that the tran-
sponder leaves the antenna field (the noise is higher than the set 100 samples for the
thresholds), each zero crossing of the difference voltage (not shown in the diagram)
will generate another POSI-Pulse.

Antenna and interpreting electronics are housed in a 360 x 160 x 91 mm casing. The
reading side of the antenna is the top of the casing with the casing cover. The three
built-in 12 pin sockets (M23; gold-plated contacts) are facing in the direction of travel.
For each antenna, a correspondingly suitable line termination resistance is included
in the scope of supply.
Inside the casing houses the completely sealed antenna electronics and the heater.
For connecting the antenna, the sockets X1 and X2 (Profibus) or the connector X3 (Po-
siPuls, RS232, power supply) are being used. The integrated LED indicates the Profi-
bus status Data exchange.
For each antenna a connection set is part of the scope of supply, including 3 connec-
tors, the terminating resistor and an inserter. The particular cable diameters have to
be indicated on order.
4.2.2 Pin allocations
The Profibus version has two 12-pin sockets for the bus and one 12-pin plug for sup-
plying the antenna.

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. In addition it can be limited to one pulse per crossing.
Both connecters for positioning are not internally connected with +24V or GND as in
some systems a strict isolation of potentials has to be kept. Due to security require-
ments the current in these outputs is limited to 20mA. If e.g. a 24 V output is needed,
contact number 9 has to be connected with +24V and contact number 10 has to be
connected with GND using a resistor of 1 KOhm.

4.2.3 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 5.2.2.4 on page 33). A further 16 seconds are necessary,

4.2.4 Interfaces
4.2.4.1 Serial (RS 232 or RS422)
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 either
“transparent“ or “3964 R“ (see also sections B on page 47 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. The crossing of the anten-
nas 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 pulse per crossing.
4.2.4.1.1 List of System Data that may be Output
A telegram of the serial output consists of max. 21 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
further (DLE) characters by this procedure.´All multiple byte variables are put out ei-
ther with the highest byte or the lowest byte first (adjustable)!
The 8 bit check sum is only output when using the transparent protocol. It then in-
cludes the start character. The start character, as well as the check sum (transparent
protocol) cannot be removed from the data block. The protocol is adjustable, irrespec-
tive of whether telegrams are output permanently by an adjustable updaterate or
whether one transponder is located within the field.

One command telegram always consists of four bytes, including the actual command
and the parameters. When using the procedure transparent it is, in addition, neces-
sary to transfer one start character and a check sum (XOR operation of all bytes in-
cluding the start character).
There are three commands:
0x1000 POSIPULS transponder crossed center of the antenna **)
0x2000
0x4000
0x8000
No. Meaning Procedure Start sign command

Further information concerning number:
1. The monitor mode should not be used during normal operation (e. g. from an
PLC), as the following output is not according to a transparent or 3964R protocol
but only suitable for display on a VT52-terminal and used for the alteration of
parameters.
2. An activated reference transponder is described by setting the corresponding
bit in the system status „0x0100“ (only valid for systems that include a reference
transponder). Please note that, while the reference transponder is activated, the
runway transponders cannot be processed unambiguously, i.e. they are either
oppressed or their position is inaccurate.
3. The successful deactivation of the reference transponder is signaled by the
deletion of the „0x0100“ bit from the system status.
4.2.4.1.3 System Monitor
In monitor mode the system is configurable via a menu. Please refer to section 5.2
„System Monitor“ on page 27.
4.2.4.2 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. In addition it can be limited to one pulse per crossing.
4.2.4.3 CAN
4.2.4.3.1 Description
Either Basic- or Full-CAN mode is configurable. The system monitor is used for setting
the CAN parameters (also refer to section 5.2.2.5 on page 35). The internal CAN mod-
ule is based on the CAN specifications V2.0 part B. It is possible to transmit either
standard or extended frames (adjustable). The system monitor is used for setting the
bit timing as well as the identifier.
It is possible to output four different CAN Message Objects and receive one. It is con-
figurable whether telegrams are output permanently according to the set update rate
or only while a transponder is within the field. In addition, remote operation is select-
able.
The objects are activated in the CAN menu by input of an address different from 0.
