1 Introduction
The individual command set of a readers or decoders manufactured by AEG ID base on standardized com-
mand sets, that are specific to each class of readers/decoders. This standardized command sets are desig-
nated as ASB, which means AEG ID Standardized Command Set. The standardized command sets make it
possible to use different hardware components (within a class of readers/decoders) without modification of
the software application.
The command set of the ARE K1 is compatible to the ASB 1.0. Beyond it the ARE K1 RS232 is provided
with a special command for self-diagnosis and extended parameter settings as well.
The difference between the command set of the ARE K1 and the ASB 1.0 is made quite clear at the rele-
vant subjects in this description.
2 Modes of operating
Three basic modes of operating are defined:
• Operating mode 0 (continous mode) - reader is automatically triggered
• Operating mode 1(external mode) - reader is externally triggered
• Operating type 2 (command mode)- reader is triggered by serial interface
2.1 Change of Operating mode
The operation mode of the ARE K1 can be changed out of each operation mode using the MD command
1
.

this behaviour is not universally applicable at ASB 1.0
--------------------------------------------------------------------------------6/26--------------------------------------------------------------------------------
2.2 Operating mode 0 - continuous mode
When operating continuously the exciter is switched on permanently. The reading cycles are initiated peri-
odically.
After an accomplished reading cycle the reading information is evaluated. After that data (either trans-
ponder number or NoRead code) is output to the serial interface.

2.3 Operating mode 1 - running externally triggered
In operation mode 1 the exciter is turned off. As soon as the external triggered signal rises from logic 0
to 1, the exciter is started and a reading process is initiated.

Figure 2.2: external triggering -limitation of the switch period through a successful reading
After a successful reading cycle, the exciter is turned off immediately (irrespective of the trigger signal).
The next reading cycle starts at the next leading edge (0 to 1) of the trigger signal.
If a reading cycle is not successful, the reading process is controlled by the state of the external trigger
signal: further reading cycles are started as long as either a successful cycle has occurred or the exter-
nal trigger signal is logic 0 again. In the latter case the identification NoRead code is output.

2.4 Operating mode 2 - reading triggered by the serial interface
In operating mode 2, the exciter is always turned off. Triggered by the command GT, the exciter is acti-
vated. After successful reading of a transponder number the exciter is turned off automatically.

Figure 2.4: software triggered reading operation
If the first reading cycle yields no result (NoRead), the on-time of the exciter is limited by the parame-
ter 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.

3 Protocol format
The command set described in this chapter defines the transfer of data on the serial interface.
The commands consist of a command code and of a parameter value optionally. Commands are termi-
nated by the control character <CR> (13H). The control character terminates the command line.
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).
3.1 Echo function
The echo function can be switched on or off.
--------------------------------------------------------------------------------9/26--------------------------------------------------------------------------------
If the echo function is activated using the EC command, every signal sent to the reader is immediately sent
back (echoed) after receipt. Thus the echo function can be used as life indication. If the reader is controlled
by a terminal, the echo function should normally be activated.
If an echo function is not intended, e.g. in automation applications where the reader might be connected to
an PLC, the echo function should be deactivated.
3.2 Entering of commands
The protocol format is as follows
command <SP> parameter <CR>
The space character <SP> separates the commands from the parameter value. The <CR> character
terminates the command line.
For commands without parameter values (e.g. GT or RST) the <SP> character and parameter values
are omitted. The command line is as short as this:
command <CR>.
3.3 Output format
Generally, every input terminated by <CR> is acknowledged by the reader. The following response proto-
cols are different:
3.3.1 Command specific response
After a correct command without parameter value is sent to the reader, the reader answers using a for-
mat, which is specific for the submitted command. Example:
Command: GT <CR>
Output: transponder number <CR> or NoRead-code
2
<CR>
3.3.2 Response to a parameter change
After entering a valid command together with a parameter value, the system answers by sending the pa-
rameter value and <CR>. Example:
Command: MD <SP> 1 <CR>
Output: 1 <CR>
2
see chapter3.10.1
--------------------------------------------------------------------------------10/26--------------------------------------------------------------------------------
After entering an invalid parameter value, the system answers with the corresponding error code (see chap-
ter 3.6 ).
3.3.3 Response to a parameter query
Parameter settings can be queried by sending the command without adding an parameter value. Example:
Command: MD <CR>
Output: 1 <CR>
3.4 Parameters
Generally a command comes with one parameter value at the most. Command code and paramter value
are separated by SP>.
3.4.1 Set of parameters
The ARE K1 is provided with three independent sets of parameters:
• the set of parameters ex work
• the set of parameters specific to the application plus
• the actual set of parameters
The set of parameters ex work enclose all original reader settings. This set is stored in the EPROM and
can’t be changed. The set of parameters specific to the application is stored in an EEPROM. This set de-
fines the configuration after a cold start. The actual set of parameters defines the actual function of the
decoder. It is stored in the RAM.
All changes of the parameter values have an effekt to the actual set of parameters only. This set is tem-
porary, that means all values are lost after switching off the decoder.
Using the VSAVE command (see chapter 4.19) the actual set can be stored permanently as set of pa-
rameters specific to the application. Then all values are loaded back automatically after a cold start.
3.5 Blank input line
If a single <CR> is input, the reader answers with a single <CR>. Example:
Command: <CR>
Output: <CR>
--------------------------------------------------------------------------------11/26--------------------------------------------------------------------------------
Please note: If echo mode is active, a single <CR> forces the reader to output <CR> <CR> (echo plus
output).
3.6 Erroneous entering of commands - error codes
If a command is not entered correctly, the reader sends one of the following error codes:
Wrong command: <NAK> #00 <CR>
Wrong parameter: <NAK> #02 <CR>
3.7 Boot message
After booting the system (cold and warm start) the software version is output as described for the VER
command (see chapter 4.17), if echo is active. If echo is disabled, no boot message will appear.
3.8 Use of capital letters
The standard operating system is not case-sensitive, that means capital- and small letters are treated the
same.
3.9 Line feed
A line feed character <LF> is not sent by the decoder. If the decoder is controlled by a terminal, a line
feed can be added by the terminal software (option: replace CR by CR LF at receipt).
3.10 Output format for the transponder number
The location of the transponder bits in the ASCII characters is shown in Table 3.1:
D38 ... D32 D31 ... D24 D23 ... D16 D15 ... D8 D7 ... D0
ASC9 ASC8 ASC7 ASC6 ASC5 ASC4 ASC3 ASC2 ASC1 ASC0
Table 3.1: data format of the transponder number

Table 3.2: example of a transponder number
--------------------------------------------------------------------------------12/26--------------------------------------------------------------------------------
The transponder ID 001F37BD92 will be transmitted on the interface using the characters 30H, 30H,
31H, 46H, 33H, 37H, 42H, 44H, 39H, 32H and <CR>.
3.10.1 Output format for the NoRead information
An unsuccessful reading cycle is represented by the NoRead character sequence (see CN command in chap-
ter 4.3). Normally the NoRead is coded by the number FFFFFFFFFF, which can never appear as trans-
ponder code.
Alternativly at the ARE K1 a NoRead information can be output using the error messages <NAK> #09
<CR>. For this the parameter value of CN has to be set to 2
3
.
3.10.2 Output of a reader number
For readers connected by a network the output of an individual reader identification is necessary, to assign
a message with the belonging sender device. This identification can be made activating the RNR function
(see chapter 4.14 - reader number). If the RNR function is active, each reader answer is preceded by a
reader number and a space character as well (i.e 15 <SP>).

different responses are possible in operating mode 2:
• Transponder number, e.g. 001F37BD92 <CR>
• NoRead, e.g. FFFFFFFFFF <CR>
• <CR> as command acknowledge, if a filter function is active, which cut
the transponder code or the NoRead result.

5 Description of hardware near functions
5.1 Cold start
After a cold start the system is initialized using the parameter values out of the EEPROM. The indica-
ting elements (relays / LEDs) are cleared.
5.2 Interface to the master
The serial interface permits communication between the reader and a master (e.g. terminal or PC). The ba-
sic configuration of the interface is 19200baud and 8N1 (8 bit, no parity and 1 stop bit). With the com-
mand BD the reader can be set to a different baud rate. Changing the data format (8 data bits, no parity, 1
start- and stop bit) is not possible. The same applies to hardware-handshaking, e.g. Xon/Xoff or RTS/CTS.
5.3 Digital trigger input
For the operating mode 1 - externally triggered - a digital input channel is required. The following logical
function is defined:
5.3.1
Logical level
If the digital input is open (not connected), then it is in the logical state zero (0). By feeding the defined
input voltage the digital input has one-level (1).
5.3.2
Timing characteristics
When triggered externally, the first reading process is initiated by a change from 0 to 1 (leading edge) -
see chapter 2.3.
5.4 Digital trigger outputs
Two specified digital outputs are defined as follows:
--------------------------------------------------------------------------------22/26--------------------------------------------------------------------------------
Output Function
QR1 trigger output - transponder read (QREAD)
QN1 trigger output - NoRead (QNoREAD)
Table 5.1: definition of the digital output channels
5.4.1
Logical level
At rest all digital outputs are logical 0. This means the rest contact is closed and the working contact is
open.
5.4.2
Logical function
The logical function of the digital outputs is determined by the particular parameter setting.
If QR1 = 2 resp. QN1 = 2, the logical function is defined as follows:
After cold- and warm start all trigger outputs are set to logical zero. After processing the reading re-
sult, the corresponding output is set to logical 1 according to Table 5.1. If both trigger outputs QR1
and QN1 are set to parameter value 2, therefore only one of the trigger outputs can be at logical 1 at a
time.
The result of each reading cycle is displayed at the corresponding digital output until the end of the next
reading process.
The data filtering functions for the serial interface (e.g. CN - suppression of the NoRead output or CID)
do not influence on the digital outputs.
5.5 Indicating elements (LEDs)
LED1: on when antenna is operated
LED2: on when last read was not successful
LED3: on when last read was a success
LED4: on as long as the digital input is high
LED5: on when a hardware error was detected
LED6: flashing as long as the reader is powered and the microprocessor is working properly
LED7: on as long as commands were received on the RS 232 interface
LED8: on as long as information is transmitted from the RS.232 interface
LED9: not used
5.6 DIP-switches
In normal condion (ex work) all DIP-switches are set OFF (down).
--------------------------------------------------------------------------------23/26--------------------------------------------------------------------------------
On
1 2 3 4 5 6 7 8
DIP-Switch
If switch 1 is in position ON, the default values (see chapter 3 - firmware) are loaded out of the EPROM at
a cold start (when reader is put in operation).
DIP-switches 2 ... 8 have no function.
--------------------------------------------------------------------------------24/26--------------------------------------------------------------------------------
6 Appendix
6.1 Glossary
Telegram: Sequence of 64 data bits transferred from the transponder to the reader.
Superimposition: Number of superimposed telegrams for an improved signal to noise ratio ad-
justed by the parameter NRD.
Reading: Interval of several telegrams, whose number is fixed by NRD. The result of a
reading is a transponder number or NoRead. In contrast to the reading process
a reading does not appear at an external interface, that means the result is
processed within the reading algorithm only.
NoRead: If it is not possible to determine a transponder number (no header, wrong par-
ity, ...), then the reader operates for the next internal operations with the trans-
ponder number FF FFFF FFFF (Hex) as NoRead information.
NID: This parameter sets the number of readings with identical transponder number,
which have to appear within one reading cycle for the result ”successful reading
cycle”.
Reading cycle: Interval of several readings. The maximum length of intervals is fixed by the
values of NRD and NID. A reading cycle is successful if within the reading cycle
the number of readings specified by NID yields the same result.
Reading process: Interval of several readings. A reading process is started with occurrance of the
trigger condition. The reading process is either terminated by occurrence of a
successful reading cycle or through a break (time out, falling edge of the exter-
nal trigger signal)

. At the end of a reading process appears always a result on
