IDE-Small-ID-Tablet/with boards 0039PBA02,0572A02 and 0573A01
REVISION 1.0, 2009-06-17
The Small-Id Tablet (it consists of parts PCB 0039PBA02,PCB 0572A02 and mounting board
0573A01) is a RFID Read-/Write-Device (short: reader) which is compatible to all Mifare cards.
The reader also supports ISO14443A/B and ISO15693 and all cards compliant to these standards.
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 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.

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 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
