read either the unique serial number of Mifare
ised ID-number out of a sector/block and standard data files. The card number will
be transmitted to the CerPass / SIPORT NT Access control system for processing.
The identification card readers have to be mounted on recess devices in accor-
dance with DIN 49 073 (60 mm perforate distance). In the top of the housing
(reader electronic) is a plug-in connector for the connection to the door control unit
DRI / ERI / CC30xx / DC2000 / K24.
The identification card readers AR6181-MS and AR6182-MS have to be connected
via a RS485 bus-interface, 2-wire, to reader interface of an door controller CC30xx
/ DC2000 / K24. For that a 4-wire, twisted pair, shielded cable is required, one pair
for the 2-wire RS485 party line and the other pair for power supply of the reader.
Max. 8 identification card readers AR618x-MS can be connected to one CC30xx
door control unit and up to 4 readers to DC2000 / K24 (Remark: DC2000 / K24 is
connectable only to SIPORT –Systems). Because of the reader protocol, the
AR618x-MS can only be used with readers of same protocol type at the one door
control unit. The maximum allowed distance between the door controller and the
identification card reader is 50 m. The door management and monitoring is con-
trolled by the door control unit.
The data transmission of the system from the user cards to the identification card
readers is based on an electro-magnetic field, which is created by the aerial of the
identification card reader. If the ID-card is introduced to the electromagnetic field of
the reader aerial, it is supplied with energy and sends its personalised data. The
data is received by the reader aerial.
The reading range of the identification card readers AR618x-MS, depending on the
kind of the arrangement and material the reader is mounted on, is up to 50mm.
The kind of the transponder ID-card has also an significant influence to the reading
distance; e.g. ID-card, keyfob, etc. Electrically conductive materials like metal and
metallised glass surfaces can influence the electro-magnetic field. The distance be-
tween the identification card reader and metallic objects must be at least 30 cm.
Otherwise, the reading range is reduced.
No two adjacent identification card readers should be closer than 50 cm to prevent
mutual interference of the electro-magnetic fields and consequent data transmis-
sion problems. Attention should also be paid not to install the identification card
readers near to computer-terminals, TV sets and so on which would reduce the
card reading range. If the identification card reader is mounted on metal walls or
metallised glass surfaces, the attached delivered mounting frames should be used.
In that case, the reading range might be reduced.
With suitable installation the reader meets protection class IP65. Avoid installing
the reader in places where it is subject to direct sunlight.
The reader has three LED's with the colours yellow, red and green and an internal
buzzer.
