ID-Tablet/0535A08E-001 with 0539A02 and 0538A06/0538A07

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.

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.
