10074-001-51
REVISION 1.0, 2009-11-24
The 10074-001-51 is a RFID Read-/Write-Device (short: reader). The reader supports
ISO14443A/B and Mifare cards. It provides an universal serial interface (USB) to output or
exchange data with a host computer and a 13.56MHz inductive interface to supply power to
and exchange data with the Mifare/ISO compliant card (or other available form-factors such
as tags, key-fobs). The host computer can control a LED to interface with the user.
Mounting and Connection
The reader generates a magnetic field with the frequency of 13.56MHz which is influenced by
any electrically conductive material in close proximity to the device. When mounting the unit,
a distance to any such material of minimum 10 cm is required to ensure that there will be no
significant degradation of the performance in terms of read range and reliability. Mounting
the unit directly to metal would result in a severe reduction of read range down to zero
functionality. Care should be taken when testing the device after mounting at a problematic
environment: Read ranges and performance vary from card to card and very much from card
to tag or key-fob.
When mounting multiple readers, the distance between readers should be minimum 0.5 m in
order to avoid degradation of performance due to interference.
Operation
Whenever the device is connected to a proper power supply, it will switch on the internal
antenna and periodically scan for a card. Once a card has been detected, the card number is
read, the data converted and sent to the host system through the serial interface. To enable the
device to read cards, tags and key-fobs successfully, they should be placed centred above the
reader.

FCC:
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:(1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is
2
connected.
-- Consult the dealer or an experienced radio/TV technician for help.
Canada:
This Class B digital apparatus complies with Canadian ICES-003.Cet appareil numérique de
la classe B est conforme à la norme NMB-003 du Canada
