Introduction
This document will describe the components of the Compact Reader System ARE i2 / RS 232 and the
procedure how to do the first set up of the reader.
The main features of the reader are listed below:
• the antenna is placed inside of the housing
• there are algorithm available to read nearly all 125 kHz-transponders on market
• integrated RS232 Interface with tunable baud rate are up to 19200 Bit/s
• the allowed supply voltage is 9 to 30V DC
• low power consumption of reader < 1.2 Watt
• high reliability for reading and writing within an industrial environment
• compact housing of the reader with multiple ways for mounting
• the cabling concept of the reader is optimised to service demands
• the protection class of the housing is IP65
• there is a set of external antennas available to meet special application demands ( X-tended version)
System overview
In the base version all electronic components of the reader are placed inside of a small plastic housing.
By means of the integrated 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
reader is fully controlled by a master with RS 232 data port, while using the integrated serial RS 232
interface of the reader.
There is a version available without the integrated antenna. On this version it is possible to connect an
external antenna.

Figure 1: Concept of the reading system
Installation
To get the specified reading performance it is necessary to do the installation carefully step by step as it
is described in the following Chapters. All the work must be done by well educated people.
3.1
Mounting of the housing
The reader can be mounted to any other mechanic construction. The distance between reader and transponder has to tuned
It is recommended to protect the housing against heavy mechanical interactions and drippy fluids.
Attention!
The side of the housing showing the antenna symbol must not be brought next to a metal surface. This
could lead to a significant change of the properties of the antenna circuit, which in turn reduces the
reading range considerably.
With the help of the plastic bars, the reader can mounted or screwed on to the most fastening elements
without open the housing of the device.
3.2
Grounding of the reader
To get reliable reading results, the reader must be grounded. The connector is placed at the side of the
housing (6.35 mm flat contact).
To avoid EMV-problems, the cable to ground ought to be very short with low impedance.
--------------------------------------------------------------------------------5/32--------------------------------------------------------------------------------
Attention!
The topology of the ground wires must be done in the right way (according state of art).
3.2.1 Connecting of the plug
Attention!
Be sure that the grounding of the reader is well done and the power supply is not connected(chapter 3.2).
Otherwise the electronic may be destroyed by electrostatic discharge (ESD).
Figure 2: Connecting of the plug
Put on the sealing 2 to the SAB Cab (A).
Plug in the SAB Cab to the connector at the bottom of the reader device (B).
There is only one way to plug in the SAB Cab to the connector rim of the reader.
Fasten the SAB Cab with the help of the screws.
To meet the protection class of IP 65, it’s necessary to apply a turning moment of 0.5 Nm to the screws.
--------------------------------------------------------------------------------6/32--------------------------------------------------------------------------------
3.3
Connecting of the power supply cable
The reader has to be supplied with 9..30V DC. The maximum output power of the power supply has to be
1.2 Watt. Be sure that you use the right polarity.

You can use any shielded five-pole cable. The allowed diameter of the cable must be in the range from
∅3,5 to ∅8mm. For this case, IP 65 is reached.
--------------------------------------------------------------------------------7/32--------------------------------------------------------------------------------
Attention!
The minimum voltage at the readers input mustn’t be lower then 9V.
The maximum length of the serial RS232 cable is 15m.
3.3.3.1 Assembling of the cable pipe
•
Breakthrough the prepared areas at the surface of the SAB Cabs. There are two prepared areas seen
at the SAB Cab: central and at one side of the cab.
•
The o-ring (3) has to be assembled proberly to the cable pipe (4) to ensure the protection class IP
65.

Mounting of the external antenna / of the AMP 4 / AMP 8
If you have an i2 with external antenna the connector is on the topside of the reading device. You just
have to plug the antenna into the connector and bold it on. Alternative you can connect an AMP 4 / AMP
8 with this connector, too.
You may not connect or deconnect an antenna or AMP 4 / AMP 8 while the reader is running. It can
cause, that the reader hangs up.

Instruction set / structure of the instruction set
5.1
General
The command set described below defines the transfer of data on the serial interface.
The commands consist of a command code and optionally of a parameter value. Commands are terminated by the control character  (13h). The control character serves as command line terminator.
Command codes and parameters, that means all letters and numerical values, are principally transmitted as a sequence of ASCII characters (the value 255 (decimal) consequently as 32H, 35H, 35H;
the command RST as 52H, 53H, 54H).
5.1.1 Entering instuctions
The protocol format is as follows
Command  parameter 
The space character  separates commands from parameters and the  character acts as
command line terminator.
For commands without parameter values (e.g. GT ) the  character and parameter values are
omitted. The command line is as short as this:
Command 
5.1.2 Output format
Generally, every input terminated by  is acknowledged by the reader. The following response
protocols are different:
--------------------------------------------------------------------------------13/32--------------------------------------------------------------------------------
5.1.2.1 Instruction specific output
After entering a valid command without a parameter value, the system answers by sending the parameter value and . Example:
Command:
GT 
Output:

5.1.2.2
Output after changing a parameter
After entering a valid command together with a parameter value, the system answers by sending the
parameter value and . Example:
Command:
MD  2 
Output:
2 
After entering an invalid parameter value, the system answers with the corresponding error code. Error
message:
Command:
MD  4 
Output:
 #02 
5.1.2.3
Output at parameter query
Parameter settings can be queried by sending the command without adding a parameter value. Example:
--------------------------------------------------------------------------------14/32--------------------------------------------------------------------------------
Command:
MD 
Output:
1 
5.1.3 Blank instuction
If a single  is input, the reader answers with a single . Example:
Command:

Output:

Please note: If echo mode is active, a single  forces the reader to output   (echo plus
output).
5.1.4 Incorrect instruction / error codes
If a command is not entered correctly, the reader sends one of the following error codes:
Wrong command:
 #00 
Wrong parameter:
 #02 
Antenna failure:
 #10 
5.1.5 Upper and lower case
The instruction set isn’t case-sensitiv.
5.1.6 Linefeed
The reader does never send a linefeed. If you use a terminal your terminal programme can add the
linefeed. You have to choose the option “displace CR with CR LF”.

The settings are directly effective.
Note: The internal reference number is deleted in the following conditions:
•
after a cold start
•
after a warm start (command line RST )
•
after entering the command line CID  1 
This causes that the next transponder code is output definitely.
Note: The filter function CID picks up the results of the complete reading cycles, while the parameter
NID proceeds from the results of single readings! The filter function CID has effect on the serial interface only.

Operating Modes of the Reader
There are two operational modes defined:
•
MD 0 - continuous mode
•
MD 2 - the reading process is triggered by the serial interface
In the next capters can you find a detailed functional description.
The default mode is MD 0.
6.1
MD 2 - Triggered by an Software Command
The master sends the command to read a transponder code. The reader answers with the code or an error
code.
If you use “read- and writable”-transponders you just get the transponder code using the command “Get
Tag” (GT).
You can execute specific commands “Read” (RD) and “Write” (WD) just in mode MD2. (capter 8)
In operating mode 2, the exciter is always turned off. Triggered by the software command (GT; RD ;
WD), the exciter is activated. After successful reading or writing of a transponder number the exciter is
turned off automatically.

Figure 9: Software triggered reading operation
If the first reading cycle yields no result (NoRead), the on-time of the exciter is limited by the parameter TOR (time out reader): Reading cycles are continuously started until either a transponder is read
successfully or the time span corresponding to the value of the parameter TOR has expired. The reader will not interrupt the last running readout cycle. If no transponder number has been read, a
NoRead is output.

defined by the value of TOR no NoRead will be output on the interface!
6.2
MD 0 - Continuous Reading
When operating continuously the exciter is switched on permanently. The reading cycles are initiated
periodically.
After an accomplished reading cycle the reading information is evaluated. After that data (either transponder number or NoRead code) is output to the serial interface

Startup and testing the reader
•
Connect the reader via cable with the serial interface (COM) from your notebook or pc.
•
Connect the reader with your power supply (9..30V DC). Look after the polarity!
•
Switch the power supply on. The yellow LED OP of the reader starts to blink.
•
Start your terminal programme. You have to set the following settings: 8 data bits, 1 start bit
und 1 stop bit, no parity check (often called 8N1), baud rate 19200 baud, no flow control(e.g.
XOFF/XON).
•
Send the command „VER “ to the reader. The reader answers with the actual firmware
version (e.g. AEG ID V1.23).
•
Send the command “MD  0 ” to the reader. The reader sends No Read messages
(e.g. „FFFFFFFFFF“ or „XXXXXXXXXX“), while there is no transponder in the antenna field
available. The red LED L3 is active. If there is a transponder in the antenna field available the
reader sends its transponder code. The green LED L2 starts to glow.
--------------------------------------------------------------------------------24/32--------------------------------------------------------------------------------
8
Basic data exchange process
The master has to send an software command to start an read or write process of the reader. After doing
all the necessary work at the readers site, the result of the reading or writing process or an failure code
is sent back to the master.
If there is used an read/write transponder, only the serial number of the transponder will be read if the
basic read command „Get Tag“ („GT “) is applied.
The data exchange of the whole memory can only be done, if the reader is set to the Mode 2 ( „selective
Read (RD) “ and „write (WD)“).
8.1
Selective read RD
• Start the reader with the command RD plus parameters (plus ). You can read out just one
block (with one parameter) or several blocks (with two parameters, first and last block number).
•
Wait for the answer
• Analyse the received answer: 8 characters plus . Allowed characters 0 to F.
The NoRead code is set to ( „XXXXXXXX“).
The result of the reading process may also be seen at the LED’s.
•
LED L2 lit, if there was a successful read.
•
LED L3 lit, if there was a No Read.
Example:
RD  20 
read block 20
RD  16  33  read all blocks from 16 to 33
Allowed values (block numbers of the transponder IC):
ALGO 9 (1 kBit; P4150, P4450, P4550)
3 ... 33
ALGO 6 (2 kBit; Hitag 1)
16 ... 63
ALGO 14 (2, 4; kBitEM4305, EM4569)
5 … 15
--------------------------------------------------------------------------------25/32--------------------------------------------------------------------------------
8.2
Writing WD
The memory of the transponder is organised in blocks, containing 32 bits. The data’s of every single
block must be changed separately.
• Start the reader with the command WD plus parameters ( plus ). The sent parameter consists
of the block address and writing data’s (8 ASCII characters).
•
Wait for the answer
• Analyse the received answer: 3 characters plus .
ACK 
Writing process was successful
NAK 
Writing process was not successful.
NOT 
The response of the transponder was not readable.
The result of the writing process may also seen at the LED’s.
•
LED L2 lit, if there was a successful write
•
LED L3 lit, if there was no successful write.
Example:
WD  20  < 0 1 2 7 A C D F >

Instructions
9.1
General Instructions
To avoid any reduction of the reading distance of the reader, the housing must not be brought next to a
metal surface. This could lead to a significant change of the properties of the antenna circuit, which in
turn reduces the reading range considerably!
To get reliable readings, the distance between reader and transponder must be within the specified reading volume.
The reading characteristic in front of the reader is not isotropic. It depends also strongly on the orientation between Reader and Transponder. To get the maximum reading distance, the orientation between
reader and transponder must be well suited. The best orientation depends on the type of antenna inside of
the housing ( ferrite – type or plane coil type) and the applied transponder (disc or glass transponder)
To get a reliable readings or writings, the time of transponder while crossing the sensitive area of the
antenna must be co-ordinated to the data transfer characteristics of transponder
In general the time depends on the speed of the transponder, the size of the transponder and the way the
transponder is mounted on the vehicle and must be verified by field tests.
Environmental electromagnetic noise may also reduce the read and write range consid-erably.
Arrangement to eliminate such troubles must be done specific to the application by the help of engineers
of the manufacturer.

9.2
Special Instructions for Using a Read / Write System
To transfer the data to the transponder or to control the selective read process, all standard transponder
types uses a 100%-pulse-gap-modulation technique.
The modulation of the magnetic field comming from the transponder and the write pattern done by the
base station, shows a lot of similarities. Therefore, read write systems may interfere each other.
Because of the antenna cable transfers the energy for the antenna field it radiates also the gap modulation. Therefore they should keep also a minimum distance, and shouldn’t lay parallel.
The minimum distance between two antennas mounted next to each other and the size of the interference
must be determined for each application itself.
Below there are listed several parameters that will influence the size of the interaction:
•
size of the antennas
•
orientation of the antennas (f.e. parallel or rectangular to each other)
•
size of transponder; distance between transponder and antenna
•
the chronological orders for reading or writing.
