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.

Figure 2: Front- (a) and rear side (b) mounting of the reader
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.

Metal free zone in immediate environment of the antenna
It must be followed to the minimum distan es shown in figure 4 and figure 5!

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 6: Optional orientation transponder – antenna
The reading field is a omplex three-dimensional fun tion whi h is relevantly influen ed by the orientation of
the transponder. With parallel orientation (see figure 6) and low interferen e the reading field in front of the
antenna (shown in figure 7) results.

Figure 7: Reading field above the longitudinal axis (AA) and transverse axis (BB)
Therefore the antenna should be mounted in su h a way, that the transponder moves along the longitudinal
axis AA - see figure 8.

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.

Plug
The reader is onne ted to the ontrol unit (PC or SPS) with a RS232 interfa e.
For power supply 12 or 24 VDC are ne essary. Che k the identifi ation plate.
The orresponding signals are onne ted to a 7-pin Hiras hmann plug on the reader side.
The plug is IP 65 prote ted.

Cable
The able, to provide power supply to the reader, and onne tion between ontrol unit and reader, is 5m long.
On the reader side it has a 7-pin Hirs hmann so ket mat hing to the plug at the reader.
For the ontrol unit side, the RS232 interfa e signals are onne ted to a 9-pin Sub D so ket.
Power supply has to be onne ted to two single strands with ord end terminals.
Pay attention not to get indu tive oupled interfering signals via the ables. Do not install it along ables ar-
rying signals with high power and frequen ies.

Power supply Don’t use a swit hed-mode,
but a linear regulated power supply.
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.
