1 Introduction
This document describes the RFID-reading device ARE DT1 LF and the set-up procedure.
The main features of the reader are listed below:
• integrated USB interface selectable either communications port (similar RS232) or HID
• USB powered (no external supply voltage necessary)
• compact design
--------------------------------------------------------------------------------4/27--------------------------------------------------------------------------------
Rev 09
2 Startup and testing the reader
• Connect the reader with the USB interface from your notebook or pc
• The reader is supplied via the USB interface. The supply differs depending on the used port. To
reach the maximal reading distance a powerfull supply is essential. A USB hub with its own
power supply can deliver this.
• In the device manager there will appear a new device (AEG ID Communications Port)
• In the brackets you see the port number of the device (e.g. COM5)
• Open the “Demo Terminal“ on the CD
• Open the menu “Settings”
• You have to set the following settings: baud rate 19200 baud, 8 data bits, no parity, 1 stop bit, ,
no flow control.
• Send the command „VER <CR>“ to the reader. The reader answers with the actual firmware
version (e.g. AEG ID Multi-ISO V2.034).
• Send the command “MD <SP> 0 <CR>” to the reader. The reader sends No Read messages
(XXXXXXXX), while there is no transponder in the antenna field available (if CN parameter ist
0). If there is a transponder present in the antenna field the reader sends its serial.
3 AEG ID instruction set
3.1 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 <CR> (0Dh). The control character serves as command line terminator.
Command codes and parameters,including 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).
--------------------------------------------------------------------------------5/27--------------------------------------------------------------------------------
Rev 09
3.1.1 Entering instructions
The protocol format is as follows
Command <SP> parameter <CR>
The space character <SP> separates commands from parameters and the <CR> character acts as
command line terminator.
For commands without parameter values (e.g. GT ) the <SP> character and parameter values are
omitted. The command line is as short as this:
Command <CR>
3.1.2 Output format
Generally, every input terminated by <CR> is acknowledged by the reader. The following response
protocols are different:
3.1.2.1 Instruction specific output
After entering a valid command without a parameter value, the system answers by sending the parameter value and <CR>. Example:
Command: GT <CR>
Output: Transponder number or No Read <CR>
3.1.2.2 Output after changing a parameter
After entering a valid command together with a parameter value, the system answers by sending the
parameter value and <CR>. Example:
Command: MD <SP> 2 <CR>
Output: 2 <CR>
After entering an invalid parameter value, the system answers with the corresponding error code. Error
message:
Command: MD <SP> 4 <CR>
Output: NAK <SP> #02 <CR>
--------------------------------------------------------------------------------6/27--------------------------------------------------------------------------------
Rev 09
3.1.2.3 Output at parameter query
Parameter settings can be queried by sending the command without adding a parameter value. Example:
Command: MD <CR>
Output: 2 <CR>
3.1.3 Blank instuction
If a single <CR> is input, the reader answers with a single <CR>. Example:
Command: <CR>
Output: <CR>
3.1.4 Incorrect instruction / error codes
If a command is not entered correctly, the reader sends one of the following error codes:
ERROR CODE MEANING
NAK #00 <CR> unknown command
NAK #02 <CR> wrong parameter
NAK #10 <CR> antenna failure
XXXXXXXX <CR> no read
ACK no error/acknowledge
--------------------------------------------------------------------------------7/27--------------------------------------------------------------------------------
Rev 09
3.1.5 Upper and lower case
The instruction set isn’t case-sensitiv.
3.1.6 Linefeed
The reader does never send a linefeed. If you use a terminal program it can add the linefeed. You have to
choose the option “displace CR with CR LF”.
--------------------------------------------------------------------------------8/27--------------------------------------------------------------------------------

Rev 09
3.3 Instructions for reading settings
3.3.1 CID – suppression of ID Codes
In the MD0 mode with CID=1 only the first of in succession identical transponder numbers is output
on the serial interface. The possibly following identical transponder numbers are suppressed, as long
as no new valid transponder number is received, processed and output. The get tag command is not
influenced by this command. NoReads do not influence the data filtering. The leds are not influenced
by this command.
Input format: CID <SP> parameter <CR>
Output (example): 0 <CR>
Parameter:
PARAMETER FUNCTION
0 No suppression
1 Suppression of equal transponder numbers
Example: A, B, C are different transponder codes, N is NoRead error code:
Sequence of reading cycles Output sequence
after filtering with
CN=0 und CID=1
N, N, ......,N, A, A, A, ....A, N,N,
.........
N, N, ......,N, A, N,
N, .......
Output sequence
after filtering with
CN=1 und CID=1
A
N. N, N, A, A, A, N, A, A, B, A,
C, C, C, .......
N. N, N, A, N, B,
A, C, .....
A, B, A, C
The settings are directly effective.
Note: The internal reference number is deleted in the following conditions:
• after a cold start
--------------------------------------------------------------------------------14/27--------------------------------------------------------------------------------
Rev 09
• after a warm start (command line RST <CR>)
• after entering the command line CID <SP> 1 <CR>
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.
3.3.2 CN – suppression of No Reads
Through the setting CN=1 the NoRead results after a get tag command or in MD0 mode are suppressed on the serial interface. The leds are not influenced by this command.
Input format: CN <SP> parameter <CR>
Output (example): 0 <CR>
Parameter:
PARAMETER FUNCTION
0 No suppression
1 Suppression of equal transponder numbers
--------------------------------------------------------------------------------15/27--------------------------------------------------------------------------------
Rev 09
3.3.3 NID – Failure Protection
NID specifies the number of identical transponder numbers, which have to appear for the result “successful reading“ within a reading cycle. In the setting NID = 1, two successive readings have to show
the same transponder number.
Input format: NID <SP> parameter <CR>
Parameter:
PARAMETER FUNCTION
0 One out of one
1 Two out of two
Output (example): 1 <CR>
Sequence of readings Lenght of the read-
ing cycle
Result of the reading cycle
NoRead 1 reading NoRead
0000125ED1, 0000125ED1 2 readings 0000125ED1
0000125ED1, 0000126ED1 2 readings NoRead
3.3.4 INIT – initialization
With the command INIT all paramters of this command set are set to the default values. After that
you can save the settings with the command VSAVE.
Input format: INIT <CR>
Output (example): ACK <CR>
--------------------------------------------------------------------------------16/27--------------------------------------------------------------------------------
Rev 09
3.3.5 LAA – LED automatic activity
The leds can be controlled by the reader or over the interface. You can set it up with the command LAA.
If the reading settings CN=1, CID=1, CE=1 (when SI=0), MD=0 and LAA=0 are set, the reader beeps
and flashes after successful reading. This setting makes sense when reader is used with HID setting.
Input format: LAA <SP> parameter <CR>
Output (example): 0 <CR>
Parameter:
PARAMETER FUNCTION
0 controlled by reader
1 manual controlling
Note: If automatic LED control is active (LAA = 1), it delays processing
the following command until switching the LED is over. If several
reading or writing accesses to the transponder are planed, switch this
function off (LAA = 0).
3.3.6 TSC – time show code
With the command TSC you can define the time in ms, after that the transpondercode is shown again,
when the CID parameter is set to 1. If TSC is 00, the code is not shown a second time.
Input format: TSC <SP> parameter <CR>
Input format (example): TSC <SP> 30 <CR>
Output (example): 30 <CR> => 30 * 100ms = 3000ms = 3 seconds
PARAMETER FUNCTION
00 TSC is not active
01..FF TSC time - in 100ms steps
--------------------------------------------------------------------------------17/27--------------------------------------------------------------------------------
Rev 09
3.3.7 TOR – maximum reading time
TOR is the timeout time for the reader. TOR is used in operation mode 2 as maximum gating time for
a reading process. The length of the maximum gating time results from the equation gating_time =
TOR * TB.
The time constant TB (time base) has always the default value 100ms.
Input format: TOR <SP> parameter <CR>
Output (example): 05 <CR>
Parameter:
PARAMETER FUNCTION
00h limits the reading process duration of exactly one reading cycle
01h..FFh limits the reading process duration to maximum 1..256 times
TB
3.3.8 VSAVE – variables save
With the command VSAVE the following parameters are saved to the internal EEPROM:
ACT, AFI2, AM, BD, CE1, CID, CN, KM1, KT1, LAA, MD, SI, TL1, TOR
Input format: VSAVE <CR>
Output (example): ACK <CR>
1
just available in the ISO 14443A standard
2

--------------------------------------------------------------------------------18/27--------------------------------------------------------------------------------
Rev 09
3.3.9 VS – variables show
With the command VS the reader shows the settings of the following parameters:
BD, CID, CN, EC, MD, NID, TOR
Input format: VS <CR>
Output (example): BD <SP> 0 <SP>
…
3.3.10 SA – algorithm selection
With the command SA the algorithm can be selected. Depending on the algorithm, the reader adapts its
communication to the transponder suitable for the chip type respectively data format that shall be used.
With parameter 0 ~ algorithm 14 ~ EM4305, EM4569 transponders additional commands to read and
write selective (RD, WD) are available. With parameter 1 ~ algorithm 5 ~ ISO FDX format there are
specific commands as well. This algorithm specific commands are listed in the “Addon_A..” documents.
Input format: SA<SP>parameter<CR>
Output (example): 1<CR>
Parameter:
PARAMETER FUNCTION (CHIP, FORMAT)
0 A14 ~ EM4305, EM4569
1 A5 ~ ISO FDX

3.4 General reading instructions
3.4.1 GT – get tag
The instruction GT executes one reading and sends back the transponder code of a transponder or the No
Read error code (e.g. „FFFFFFFFFF“ oder „XXXXXXXXXX“).
Input format: GT <CR>
Output (example): 0420212E5F <CR>
3.4.2 MD – mode of operation
There a two modes of operation available. It is possible, that the reader reads constantly or triggered by
an instruction.
Input format: MD <SP> parameter <CR>
Output (example): 2 <CR>
Parameter:
PARAMETER FUNCTION
0 constant reading mode
2 single reading mode
3.4.3 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 <CR>“) 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)“).
--------------------------------------------------------------------------------20/27--------------------------------------------------------------------------------
Rev 09
3.4.4 RD – read page
• Start the reader with the command RD plus parameters (plus <CR>). 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 <CR>. 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 <SP> 20 <CR> read block 20

4 Operating modes of the reader
In the AEG instruction set 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 2.
4.1 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.
You can execute specific commands “Read” (RD) and “Write” (WD) just in mode MD2.
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.

4.2 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

5 Instructions
To avoid any reduction of the reading distance of the reader, the reader must not be brought next to a
metal surface (e.g. don’t put metallic sticker to the reader). This could lead to a significant change of
the properties of the antenna circuit, which in turn reduces the reading range considerably or causes
reading holes!
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.
To get a reliable readings or writings, the time of transponder while crossing the sensitive area of the
antenna must be coordinated 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 considerably.
Arrangement to eliminate such troubles must be done specific to the application by the help of engineers
of the manufacturer.
