Introduction
This do ument des ribes the te hni al features of the ARE i5 MTL reader with air- ore oil and integrated
de oding ele troni . It ontains instru tions for start-up and su essful and durable operation. To rea h the
maximal reading distan e, a orre t installation is essential.
The devi e an read transponders appropriate DIN/ISO 11784/11785: FDX-B, HDX, Destron, Datamars.
Additional Trovan and transponders with ASK 64bit Man hester oding (e.g. Chip EM 4102).
The implemented ommand set is downward ompatible to the standard ommand set ASB 1.0. The ARE i5
uses a subset of the ASB 1.0 ommand set.

The antenna an be atta hed through the mounting holes at a suitable plate. Don’t ex eed 2 [N/m] when
tightening the s rews.
Be ause of the fun tional prin iple it must be taken are that the antenna is not indu tively short- ir uited by
the mounting onstru tion. Espe ially the dire t mounting on a frame or a plate of metal provoke su h a
short- ir uit and an lead to a destru tion of the antenna. When mounting on a on rete wall it is to noti e
that this wall may ontain reinfor ing iron in an unfavorable geometry. In this ase only a power dissipation
o urs be ause of the distan e of the iron-stru ture, but not a omplete short- ir uit. In this onfiguration the
reading range is lower than spe ified and the urrent onsumption is higher than normal.

Figure 3: False handling of the antenna
When operating an antenna in laboratory it must be paid attention that the antenna in operation must not be
laid on another antenna. In su h a ase also an indu tively short- ir uit takes pla e whi h may lead to a de-
stru tion of the antenna.
Two adja ent antennas should have a distan e of at least 50 m to ea h other.

O timal orientation of the antenna to the moving direction of the trans onder
The antenna should be mounted as lose as possible at the site of the transponder. As a rule a parallel orien-
tation of the antenna to the transponder is favorable in regard of the reading range.

Figure 9: Disadvantageous motion paths of the transponder over the antenna
A transponder has to be long enough in the a tive reading area to a hieve a reliable reading result. The max-
imum reading distan e will be a hieved only in stationary operation. The reading range is redu ed with a
transponder in motion. Therefore the transponder has to be passed loser at the antenna.

Interface – RS 232
Via the serial interfa e the ARE i5 is ommuni ating with it’s ontrol unit (e.g. with a terminal program on
the PC). The onfiguration parameters must be 19200 Baud transfer rate, 8 data bits, no parity and one stop
bit (8N1). There is no hardware handshake (Xon/Xoff or RTS/CTS) supported.
Cold start
After a old start the reader is initialized with the parameters saved in the internal nonvolatile memory. Eve-
ry hanged parameter is automati ally saved. The devi e starts with the same onfiguration it was swit hed
off.

--------------------------------------------------------------------------11/21------------------------------------------------------------------------------------
Command set of the reader / command format
General
The ommand set, des ribed in this hapter, defines the data ex hange via the serial interfa e.
The ommands onsist of a ommand ode and optional a parameter value. A ommand is ompleted by a
arriage return <CR>. It is used to dete t the end of a ommand line.
Commands and parameters, that means letters and numbers, are transferred as ASCII ode (e.g. the value
255 (de imal) is transferred as 0x32 (hex), 0x35, 0x35; the ommand RST as 0x52, 0x53, 0x54).
In ut
The proto ol has the following format:
<Command> <SP> <Parameter> <CR>
The spa e hara ter <SP> is used as partition between ommand and parameter. The <CR> hara ter is
used as end of the ommand.
Commands without parameters (e.g. GT or RST) are shorter:
<Command> <CR>
Out ut
Every input, that ends with a <CR>, is answered by the reader.
Following different answers are possible:
Command s ecific answer
After orre t input of a ommand without parameter, the reader answers ommand spe ifi e.g:
Command: GT <CR>
Answer: <Transponder number or no read message> <CR>
Command: MD <CR>
Answer: <Parameter, in this ase operation mode value, 0 or 2> <CR>

--------------------------------------------------------------------------12/21------------------------------------------------------------------------------------
Answer to a arameter in ut
After input of a valid parameter value, the reader answers with the new parameter value and a <CR>. The
new parameter value has been saved. Example:
Command: MD <SP> 2 <CR>
Answer: 2 <CR>
After input of a invalid parameter value, the reader answers with the a tual valid parameter:
Command: MD <SP> 4 <CR>
Answer: 2 <CR>
Answer to a arameter request
Parameter values an be read by using the parameter ommand without a parameter value. Example:
Command: MD <CR>
Answer: 2 <CR>
Em ty in ut line
If only a <CR> sent, the reader answers with a <CR>. Example:
Command: <CR>
Answer: <CR>
Ca ital and small letters
The reader interfa e does not a t ase sensitive. Captial and small letters are treated the same.
Carriage return
The reader does not send a line feed <LF>. Our terminal programs repla e the <CR> by a <CR><LF>. Some
programs like the “HyperTerminal” provide this as an option.

--------------------------------------------------------------------------13/21------------------------------------------------------------------------------------
VER – Software version of the reader
The ommand VER asks the reader for its software version.
Input format: VER <CR>
Output: i5_XXXXX <CR>
e.g. i5_MTR09 <CR>
MD – O eration mode
The operation mode of the reader is hanged with the ommand MD.
Input format: MD <SP> <Parameter> <CR>
Parameter:
Parameter Fun tion
0 Continuous reading mode
2 Command mode
Output (e.g.): 2 <CR>
Note: In software version MTR15 MD parameter is not saved.
The reader is starting in ommand mode. If it is hanged
to ontinuous reading mode the reader does not respond to
ommands any longer. It is ex lusively sending
transponder odes or no read messages. To swit h it ba k
to ommand mode it has to be restarted.
GT – Reading command get tag
The ommand GT starts a reading attempt. See hapter “Operation modes” “MD 2 – Command mode”.
Input format: GT <CR>
Output (Example): Depending on the parameter settings and the read transponder signal there are
three different answers possible:
• Transponder number, e.g. 001F37BD92 <CR>
• No read message, XXXXXXXXXX <CR>
• <CR> as a ommand a knowledgement, if a filter fun tion is a tive, that
suppresses transponder ode or the no read message.

--------------------------------------------------------------------------14/21------------------------------------------------------------------------------------
CID – Su ression of equal ID codes
If the parameter CID is on value 1 the transponder ode is only sent on e, if the same transponder is read
several times. Only with a new transponder the new ode is sent ba k after a su essful reading. No reads do
not affe t this fun tion.
Input format: CID <SP> Parameter <CR>
Parameter:
Parameter Fun tion
0 No filter fun tion
1 Suppression of multiple read equal IDs
Output (Example): 0 <CR>
Annotation: In operation mode MD 2 suppression of equal ID odes is not allowed.
Example: A, B, C are different transponder numbers, N is a no read:
Sequen e of reading y les Output sequen e after
filtering with CN=0
and CID =1
Output sequen e after
filtering with CN=1
and CID =1
N, N, ......,N, A, A, A, ....A, N,N, ......... N, N, ......,N, A, N, N, ....... 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
Table 1: Example for the effe t of the filter fun tion CID
Effe t: The filter is a tive immediately after the ommand CID <SP> 1 <CR>.
Annotation: In the following ases the omparison number is deleted:
•After a old start.
•After input of the ommand line CID <SP> 1 <CR>.
The transponder read next is shown for sure.
Attention: The filter fun tion CID analyzes several reading y les. The Parameter NID only has an
effe t on one reading result. With CID a tive the reading is exe uted but the result is even-
tually not sent to the serial interfa e.

--------------------------------------------------------------------------15/21------------------------------------------------------------------------------------
CN – Su ression of no reads
When the parameter CN is on value 1, the no read messages on the serial interfa e are suppressed.
Input format: CN <SP> Parameter <CR>
Parameter:
Parameter Fun tion
0 No reads output on the serial interfa e
1 Suppression of no reads on the serial interfa e
Output (Example): 0 <CR>
Annotation: In operation mode MD 2 a suppression of the no reads is not allowed. If it is a tivated
anyway, in MD 2 mode only a <CR> is sent to the interfa e, when normally a no read
appears.
NID- Error rotection on reader level
NID spe ifies the amount of equal reading results ne essary for a su essful reading y le. If the parameter
NID is set to the value 1, the reader internally has to read two times the same transponder number before
sending one su essful reading result.
Input format: NID <SP> Parameter <CR>
Parameter:
Parameter Fun tion
0 One out of one (no effe t)
1 Two out of two
Output (Example): 1 <CR>
Sequen e of single readings Length of one reading y le Result of one reading y le
NoRead 1 reading No read
0000125ED1, 0000125ED1 2 readings 0000125ED1
0000125ED1, 0000126ED1 2 readings No read
Table 2: Example of reading y les with NID=1

--------------------------------------------------------------------------16/21------------------------------------------------------------------------------------
TOR – Maximal reading time
TOR is a timing parameter of the reader. It is used in operation mode 2 to limit the reading attempts. The
maximal time for one reading y le is TOR * TB. The timing parameter TB (Time base) has the default value
100 ms. One reading y le an onsist of several single reading attempts, until one is su essful, or TOR time
is expired. From external one reading y le looks like one single reading.
Input format: TOR <SP> Parameter <CR>
Parameter:
Parameter Fun tion
2 Limitation of the reading attempts to approx.2 times TB
3 Limitation of the reading attempts to approx.3 times TB
...
999 Limitation of the reading attempts to approx. 999 times TB
Output (Example): 2 <CR>
BUZ – Buzzer
The su essful reading of a transponder an be shown by an a ousti signal. The buzzer is a tivated or dea -
tivated with the BUZ ommand.
Input format: BUZ <SP> Parameter <CR>
Parameter:
Parameter Fun tion
0 Buzzer off
1 Buzzer on, output in Good and Bad Read ase
2 Buzzer on, Good Read indi ation only (Default value)
Output (Example): 2 <CR>

--------------------------------------------------------------------------17/21------------------------------------------------------------------------------------
ALGO – Algorithm
The reader supports 8 algorithms respe tively transponder formats. With the parameter ALGO every single
algorithm an be a tivated or dea tivated. With the hexade imal format of the parameter, every possible
ombination of algorithms an be masked. 00 means no algorithm, FF means all 8 algorithms.

FF All Algorithms a tivated (Default value)
Output (Example): FF <CR>
CM – Measurement signal strength of the trans onder, noise level
The output of the antenna re eive path is used to al ulate a RMS value. The sour e of this signal is the
transmission power of a transponder, or the ba kground noise if there is no transponder in the antenna field.
Input format: CM <CR>
Output (Example): 4 hex hara ters <CR>

--------------------------------------------------------------------------18/21------------------------------------------------------------------------------------
CD – Code resentation

1 ISO animal e.g. 968 000000547368
2 ISO industry
3 ISO BDE
Output (Example): 2 <CR>
O eration modes
Two operation modes are defined:
•Operation mode 0 – Command mode
•Operation mode 2 – Continuous reading mode
In the following hapters their fun tionality is des ribed.
MD 2 – Command mode
The ommuni ation partner is sending the ommand „Get tag“ („GT<CR>“) to start a reading attempt. The
result, the transponder ode or a no read message, is sent ba k.
In operation mode 2 the ex iter is normally swit hed off. Triggered by the GT ommand input the ex iter is
a tivated. When the reading y le is finished, it is swit hed off again.
Figure 11: Software triggered reading mode

--------------------------------------------------------------------------19/21------------------------------------------------------------------------------------
If the first reading attempt is not su essful there are more reading attempts until the TOR time is expired or
one reading attempt was su essful (reader re eived the ID ode by the transponder). During the whole read-
ing y le the ex iter stays on. If all reading attempts stay unsu essful a no read message is sent to the om-
muni ation partner. If reading was su essful the ID ode is sent.
Figure 12: Software triggered reading mode with TOR > 0
Attention: During a reading y le, during the TOR time, there is no no read output in operation mode 2!
This operation mode is fa tory setting. For further onfiguration and adaption to the appli ation, use the fol-
lowing ommands:
MD 2 Command mode
CID 0 No suppression of equal ID odes
CN 0 No suppression of no read messages
TOR XYZ Maximal time the ex iter is on. Maximal reading time x 0,1s. It takes this time until a no
read message is sent.
TOR 5 – fa tory setting
NID X Additional error prote tion. Internal omparison of the transponder odes.
NID 1 – 2 out of 2 sele tion
NID 0 – 1 out of 1 sele tion (no error prote tion on reader level)

--------------------------------------------------------------------------20/21------------------------------------------------------------------------------------
MD 0 – Continuous reading mode
The reader tries ontinuously to power up a transponder and to read it’s ode. External triggering is not ne -
essary.
Figure 13: Continuous reading pro ess
This operation mode an be onfigured with the following ommands:
MD 0 – Continuous reading
CID X - Setting of the equal ID ode suppression.
CID 0 Equal ID odes are read several times.
CID 1 Suppression of equal ID odes.
CN X - Setting of the no read message output.
CN 0 No suppression of no read messages.
CN 1 Suppression of no read messages.
NID X Additional error prote tion. Internal omparison of the transponder.
NID 0 - 1 out of 1 sele tion
NID 1 2 out of 2 sele tion
