1Introduction

This document describes technical features and directions for installation of the Long Range Reader with external

antennas due to read the following types of transponders, some defined in ISO 11784 /11785:

FDX-B

HDX

Destron

Datamars

Trovan

PSK with an side band carrier of fc/2 and 16 field cycles per bit

furthermore Read-Only transponder using ASK 64bit Manchester encoding with an data transfer

rate of 2 kBaud( e.g. EM 4102)

By means of the external antenna the reader generates an alternating magnetic field, which powers the transponder.

Coded signals sent back from the transponder are received and decoded by the reader. The result is fed via the RS

232 interface to the next level of the evaluating system

The comands to control the operation of reader uses parts of the ASB 1.0.

2Installation of the Reader

2.1 Using Serval Readers within a Close Operating Area

A synchronisation of the readers is not available.

Therefore the operation of serveral readers within an close area may reduce the reading performance of the readers

significantely. The reduction of the reading performance must be tested.

2.2 Reading Performace

The reading range and the reading area depends on size of the applied antenna. The decoder will only work with a

Passive Two Coil Antenna AAN PT for example

Typ: AAN PT8 flex. 2m

--------------------------------------------------------------------------------5/20--------------------------------------------------------------------------------

3Electrical and Meachnical poperties

The reader is connected to an master and the power supply by an standard cable. The used power supply must be set

to U = 12 V (Id 1000496, 1005442) or 24 V (Id 1004083, 1005451) /DC I = min. 1A.

Check the identification plate.

3.1 DataPort and Power Supply Cable

The length of the cable is set to 10 m.

3.2 Antenna Cable and Fine Tuning

The antennas delivered with the reader, are well tuned by the manufacturer. If there is a change of the length of the

antenna cable necessary, or the interaction between antenna and the mounting parts are too high, or another anten-

na is used, a loss in the reading distance is possible. Then a retuning of the resonant circuit of the antenna must be

done by the customer himself. To optimise the sending circuit, capacitors must be added. The fine tuning procedure

must be done very carefully and in small steps.

Fine Tuning Area. Starting from the right side:

4,7nF / 2,2nF / 2,2nF / 1,0nF / 470pF / 330pF / 220pF / 150pF / 100pF / 100pF

At delivering state a small quantity of capacitors are added to the decoder.

To get the best reading results, the power consumption of the reader should be around 5.4-6.6W. The easiest way is

to measure the current in continnous reading mode (MD 0) without a transponder in the antenna field. Current

should be 450-650mA with 12V-readers and up to 225-275mA with 24V-readers. There is no risk of damage if

power consumption is higher but reading distance decreases again. The best way is to search maximum current

consumption with the capacitor jumpers and remove or add a small capacitor afterwards.

The used capacitors must withstand antenna voltage up to 1000 V AC

--------------------------------------------------------------------------------6/20--------------------------------------------------------------------------------

3.3 Housing

The housing of reader is made of aluminium and meets the protection class of IP 65.

The size of the housing is 220 x 120 x 80 mm.

--------------------------------------------------------------------------------10/20--------------------------------------------------------------------------------

5Operation modes

Two operation modes are defined:

Operation mode 2 –Command mode

Operation mode 0 –Continuous reading mode

In the following chapters their functionality is described.

5.1 Command Mode –MD 2

The communication partner is sending the command „Get tag“ („GT<CR>“) to start a reading attempt. The

result, the transponder code or a no read message, is sent back.

In operation mode 2 the exciter is normally switched off. Triggered by the GT command input the exciter is

activated. When the reading cycle is finished, it is switched off again.

Figure 1: Software triggered reading mode

If the first reading attempt is not successful there are more reading attempts until the TOR time is expired or

one reading attempt was successful (reader received the ID code by the transponder). During the whole read-

ing cycle the exciter stays on. If all reading attempts stay unsuccessful a no read message is sent to the com-

munication partner. If reading was successful the ID code is sent.

Figure 2: Software triggered reading mode with TOR > 0

Attention: During a reading cycle, during the TOR time, there is no no read output in operation mode 2!

--------------------------------------------------------------------------------11/20--------------------------------------------------------------------------------

This operation mode is factory setting. For further configuration and adaption to the application, use the fol-

lowing commands:

MD 2 Command mode

CN 0No suppression of no read messages

TOR XYZ Maximal time the exciter is on. Maximal reading time x 0,1s. It takes this time until

a no read message is sent.

TOR 5 –factory setting

5.2 Continuous reading mode –MD 0

The reader tries continuously to power up a transponder and to read it’s code. External triggering is not nec-

essary.

Figure 3: Continuous reading process

This operation mode can be configured with the following commands:

MD 0 –Continuous reading

CN X - Setting of the no read message output

CN 0 No suppression of no read messages

CN 1 Suppression of no read messages

6.9 NoRead Information Format

An unsuccessful reading cycle is represented by the NoRead character sequence (see command CN in chapter).

The NoRead is coded by the number XXXXXXXXXX, which can never appear as transponder code.

--------------------------------------------------------------------------------14/20--------------------------------------------------------------------------------

7Set of Commands

7.1 Start Reading –GT

The reading command code is GT. For details to this function see chapter.

Input format: GT <CR>

Output (example): Dependent of the parameter settings and the actual antenna input signal, three

different responses are possible in operating mode 2:

Transponder number, e.g. 001F37BD92 <CR>

. XXXXXXXXXX <CR>

<CR> as command acknowledge, if a filter function is active, which cut

the transponder code or the NoRead result.

Note: The command is always effective in operating mode 2.

According to the hardware implementation it is not definitely ensured that this

command is executed as well in other operating modes.

7.2 Code Presentation –CD (ISO Transponder Only)

The code presentation of an ISO Transponder can be changed only, by changing the value of the value of the CD-

Paramenter:

os Reading Mode. In the MD 2 any way a <CR> is sent to the master.

7.6 Firmware Edition –VER

The command VER shows the software version of the reader. The software version is permanently stored in the

program memory together with the firmware.

Input: ‘VER‘ <CR>

Output (Example): ‘I5_MTR12‘ <CR>

7.7 Measurement of the Signal Strength of the Transponder or

Measurement of the Environmental Noise Level –CM

8Installation of the Reader

8.1 First Steps

Connect the reader to a power supply and a master (PC).

Test the communication status by using a simple terminal software. Read the edition version of the Firm-

ware by sending the VER –Command.

Test the reader with the „GT“ command.

The maximum reading time of the reader –TOR-Parameter –must be fixed to the needed value.

8.2 Failure Management

If the reading is not sucessful, please check following failure modes:

Baud rates of the Terminal Software und ARE i5 is not the same.

There is big influence of electromagnetic noise.

The Antenne is mounted direct to a conductive plate or the interaction between mounting structure and

antenna leads to shift of the resonant frequency of the exciter circuit. A retuning is necessary.
