REVISION 1.0, 2009-05-27
The IDT is a RFID Read-/Write-Device (short: reader) which is compatible to read and write to
4k-Mifare cards. All functions of reader can be controlled over USB- Interface or RS232-interface
which allows data exchange with a host computer. This includes:
• switch on/off RF-Field
• read/write to a transponder
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 1 m in order to
avoid degradation of performance due to interference.

General regulatory requirements
FCC:
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
2
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 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
