FEATURES
• Multi-tag operation (anticollision)
• Read and write distances up to 1000 mm
• Digital signal processor to reduce noise sensitivity
Inductive coupling helps you to achieve operating ranges
up to 1000 mm and the use of cryptography guarantees
highest data security.
• Communication with all HITAG transponders and
various other 125 kHz transponders
• Data encryption and key handling
• Easy system integration
Anticollision mode, which is used only in long range
operation, allows you to handle several transponders that
are within the communication field of the antenna at the
same time, thus achieving highest operating security and
permitting to handle several data transfers quickly and
simultaneously. In this context anticollision becomes an
essential element of applications such as ski-ticketing and
long range access control. With applications of that type it
will always happen that several transponders arrive in the
communication field of the antenna at the same time.
• Three interface options
• Meets all requirements for CE and EMI approval.
2
APPLICATIONS
• Universal and flexible reader module for long range
systems.

POWER SUPPLY
The HITAG long range reader module (see Fig.3) is a part
of a complete Radio Frequency Identification (RFID)
system which consists of:
The HTRM800 must be supplied from an external power
supply with +15 V and −15 V (see Section 10.3).

Reader module hardware
7.1.1
TRANSPONDERS
7.3.1
MICROCONTROLLER
The HTRM800 can communicate with transponders based
on Philips HITAG 1 and HITAG 2.
The microcontroller is placed on the HITAG core module
(see Fig.1) and processes the protocol for the
communication between the transponders and the reader
module. The interface signals are converted so that the
transponders are able to process them and the outgoing
signals from the transponders are converted into
interface-compatible signals.
7.1.2
ANTENNA
The antenna is an important part of the HITAG long range
system. The antenna must provide energy and data
transmission between the reader module and transponder.
The second essential microcontroller function is its control
function. The microcontroller activates and deactivates the
transmitter and switches the receiver between the modes
for the different transponders reception.
7.1.3
HOST SYSTEM
The connection to the host system (e.g. microcontroller
or PC) is a serial interface on RS232 level for data
transmission.
Additional functions of the microcontroller are controlling
the standby mode of the amplifier, detection of detuned or
broken antennas (antenna malfunction) and controlling of
the input and output for general purpose.
7.1.4
I/O FUNCTIONS
One line of the HTRM800 is wired as input from e.g. a
switch and one line as output to drive a LED.

INTERFACE MICROCONTROLLER TO HOST
reader module and transponder the located disturbers are
eliminated. The command StartFFT should be executed
as often as the application allows.
The device communicates with the host system via a serial
interface using a baud rate of 9600 baud. Data transfer
details are: 1 start bit, 8 data bits, 1 stop bit, no parity bit
and the least significant bit is sent first.
Remarks:
1. The DSP is able to suppress up to two harmonic
electromagnetic disturbances
Version HTRM800/AED has an integrated RS232 level
driver. Version HTRM800/CED is wired with an RS485
level driver and version HTRM800/EED is wired with a
CMOS level driver.
2. During FFT is running (about 110 ms) communication
with a transponder is not possible.
7.3.7
VOLTAGE REGULATING UNIT
7.3.3
TRANSMITTING PART
The reader module contains some filtering circuits which
supply all parts of the reader module with the required
voltages. Nevertheless some requirements are to be
fulfilled by the external power supply. This means the
maximum ripple of the supply voltages must not exceed
the values specified in Chapter 8.
For transmitting power and data to the transponder a
125 kHz sine signal is switched by the microcontroller and
amplified. The amplifier is designed as a current source.
A voltage limiter is used to clamp the output voltage of the
amplifier during the decay and transient phases of the sine
signal.
7.3.8
STANDBY MODE
7.3.4
RECEIVING PART
The HTRM800 offers a software controlled standby mode.
This mode can be activated and deactivated by the host
system. During the standby mode the amplifier is turned off
and the power consumption decreases drastically.
After filtering and demodulation of the amplitude
modulated signal received from the transponder, the
received data is converted and passed to the Digital Signal
Processing (DSP) unit for further processing.
7.3.9
BEHAVIOUR WITH HITAG 1 TRANSPONDERS
7.3.5
DIGITAL SIGNAL PROCESSING UNIT
If several HITAG 1 transponders arrive simultaneously
within the communication field of the antenna of a
HTRM800, all the transponders (theoretically up to 232)
within the communication field of the antenna can be read
and written simultaneously. Because of the mutual
influence of the transponder coils - they detune each other
if there are too many too close to each other - the number
of the transponders that can be operated simultaneously is
limited.
The receiving part of the reader module includes
bandpass filters which attenuate disturbances (3 dB
attenuation at 105 and 145 kHz). For disturber
frequencies near the 125 kHz (e.g. harmonics of the line
frequency of PC monitors, long wave transmitters) a
fourier transformation is used to recognize harmonic
disturbers and to eliminate their influence. The DSP is also
responsible for separating the responses of different
transponders during anticollison cycles (multiple
transponder operation).
7.3.10 BEHAVIOUR WITH HITAG 2 TRANSPONDERS
If several HITAG 2 transponders arrive simultaneously
within the communication field of the antenna of a
HTRM800, the ‘stronger’ transponder (the nearer one)
takes over or - under special circumstances - no
communication takes place. If the transponders arrive in
the field one after the other, communication is established
with the first one, all the other transponders are ignored.
This ensures that no two (or several) HITAG 2
transponders will ever be processed (above all written to!)
accidentally at the same time. By muting a selected
HITAG 2 transponder (HALT mode) another HITAG 2
transponder that is to be found in the communication field
of the antenna can be recognized.
7.3.6
PERIODIC DISTURBERS
There are a couple of possible sources for disturbances for
a 125 kHz system like HITAG. The HTRM800 is designed
to handle this problem and achieve optimal performance
under worst conditions.
Long wave transmitters, other 125 kHz systems and
PC monitors are examples for periodic disturbers which
can be relevant for 125 kHz systems. To eliminate these
disturbers the digital signal processing unit is used.
After the command StartFFT is sent to the reader module
a Fast Fourier Transformation (FFT) is started to locate
periodic disturbers. After about 110 ms this calculation is
finished and for the following communication between

Operating security
By muting a selected transponder (HALT mode) another
transponder that is to be found in the communication field
of the antenna can be recognized.
The following mechanisms ensure the operation security
of the HITAG system:
• Anticollission mode
7.5.2
MONITORING THE SUPPLY VOLTAGE
• Monitoring the supply voltage
• Antenna rupture and short circuit.
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.
7.5.1
ANTICOLLISION MODE
Anticollision mode in long range applications permits you
to process several HITAG 1 transponders simultaneously.
Theoretically up to 232 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.
7.5.3
ANTENNA RUPTURE AND ANTENNA SHORT-CIRCUIT
The HTRM800 does not get permanently damaged in case
of an antenna rupture or a brief antenna short-circuit. The
detection of detuned or broken antennas (antenna
malfunction) is possible.

Security considerations
To make use of cryptography for HITAG 2 transponders
you need:
Developing the HITAG system special consideration was
given to aspects of security. The following items represent
the fundamental framework of the security concept:
• A key which is used to initialize the crypto block using
HITAG 2 in crypto mode
• Passwords which are used for authentication for
HITAG 2 in password mode.
• Cryptography
• Mutual authentication
• Password verification
• Cyclic Redundancy Check (CRC).
The transponders and the HTRM800 are provided with
identical transport keys and transport logdata so that you
can start operating them right away (see Table 2).
In order to offer our OEM clients high flexibility, the
configuration of the transponder memory, password, keys
and logdata can be changed. We strictly recommend to
rigorously restrict these possibilities for the end customers
(by setting the configuration page to read only, setting
password, keys and logdata to neither read nor write).
7.6.1
DATA PRIVACY
The use of cryptography (stream cypher), mutual
authentication, and password verification prevents
monitoring and copying the data channel. Therefore, the
area of the transponder that only can be accessed
enciphered is called ‘secret area’.
To make use of cryptography for HITAG 1 transponders
you need:
• Keys to be used for initializing of the crypto block
• Logdata to be used for mutual authentication.

10 APPLICATION INFORMATION
10.2 Distance between two antennas
10.1 Metallic environment and interferences
In order to be able to operate two systems side by side
without negative influence on communication ranges, you
must place the antennas at a minimum distance. To keep
this distance low, magnetic shielding must be realized.
This topic is handled in detail in application note “Antenna
Design for the HITAG Long Range System”.
The communication range is impaired by metallic
environment and electromagnetic interferences
(e.g. monitors and keyboards). Therefore, you should
keep a distance of at least one time the antenna diameter
to metallic surfaces or loops as well as to electromagnetic
interferences. If this is not possible, you have to take
preventive measures such as using ferrites or shielding for
transponder and antenna.
10.3 External power supply
Instead of a transformer type supply unit (see Fig.5),
a switching frequency power supply unit can be used
alternatively. The switching frequency must be in the
range from 165 to 210 kHz (overtemperature, load and
production).
The HTRM800 is able to suppress up to two harmonic
electromagnetic disturbances.

10.5 Building HITAG long range antennas
10.5.1 BASICS
The following error list should be checked if any error
(e.g. read or write distances that do not reach the specified
values) occurs:
The exact way how to design a HITAG long range antenna
is described in application note “Antenna Design for the
HITAG Long Range System”.
• Power supply cable not mounted correctly
• Power supply voltage not in the specified range
• Serial interface not connected correctly
The antenna is an important part of the HITAG long range
system. The antenna must provide energy and data
transmission between the reader module and transponder.
Therefore, you should be particularly careful when
implementing the antenna in order to achieve optimum
results.
• Interference received by the antenna because of an
external noise source (e.g. monitor, keyboards); the
remedial measure is to remove the antenna from the
interfering area and use the command StartFFT
The equivalent circuit of the antenna is shown in Fig.6.
• Connecting cables of the antenna changed by mistake
The requirements of the antenna coil are:
• Antenna is mounted in metal environment; the remedial
measure is to mount a non-metal space keeper between
the antenna and the metal
• Quality factor: Q = 30 to 60

10.5.2 RECOMMENDED ANTENNA CABLE AND LENGTH
10.5.7 ADDITIONAL REMARKS
The length of the antenna cable should be limited with five
meters. In case of longer cables a type with low
The following list is a summary about HITAG long range
antennas:
capacitance and resistance must be used. For standard
applications a 50 Ω coaxial cable is recommended and a
75 or 95 Ω coaxial cable for special applications.
• Philips lays high emphasis on the research of antenna
development
• The choice of various antenna shapes (the electrical
parameters) is characteristic to 125 kHz systems
10.5.3 TUNING OF THE ANTENNA CURRENT
• The knowledge is transferred to Philips customers, in
order to enable them to design and build antennas which
fit best for the particular applications (antenna training)
Potentiometer R72 (see Fig.2) is used to tune the current
driven through the antenna. The default setting is 200 mA.
It is not customary to change this value. However, if you
want to change the current for a special application, it
should be noted that Vo(peak) < 10 V.
• Solutions can be found for almost every environmental
scene (metal, periodic disturbers, special antenna

10.5.4 TUNING OF THE ANTENNA PHASE
10.6 Antenna arrangements
The signal from a transponder is delayed by the decay
time of the antenna. To achieve optimal performance this
signal and the digital signal processing unit of the reader
module must be synchronous. Thus it is necessary to store
a phase information called Bit Clock Delay (BCD), which is
a function of the quality factor and the inductance
(reactance) of the antenna.
Various arrangements are suitable for different
applications (see Fig.6):
• The single loop antenna is used for standard
arrangements
• The gate antenna is used for typical access control
applications such as access control during passing
through the gate
The default setting is 7 which is suitable in most of the
cases. Apart from that, the user is able to change the BCD
value. The reader module includes a non volatile memory
(EEPROM) to store the bit clock delay. To load the BCD
value to the reader module the command SetBCD is used.
• The double gate antenna is similar to the gate using two
rows
• The antenna multiplex system is a cost efficient
application, because one reader module drives many
antennas and the number of multiplexed antennas is
only limited by timing restrictions.
10.5.5 HITAG ANTENNA TUNING DEVICE
Especially for the HITAG product line the HITAG antenna
tuning device HTOT840 was designed. This tuning device
can be used for tuning long range and proximity antennas.
By changing the arrangement of the antenna, the total
system performance and reliability can be significantly
improved. As an example: building gate antennas with
opposite magnetic orientation leads to a very reliable
system.
10.5.6 ANTENNA MALFUNCTION INDICATION
If the antenna is broken or badly detuned, the antenna
overload bit is set. This bit can be read by the host system
via the serial interface by using the command
ReadLRStatus.
