WARNING TO USERS IN THE UNITED STATES
Federal Communication Commission Interference
Statement 47 CFR Section 15.105(b)
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 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.
This device DTE4027 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.
NO UNAUTHORIZED MODIFICATIONS
47 CFR Section 15.21
CAUTION: This equipment may not be modified, altered, or changed in any way
without signed written permission from BIO-RAD. Unauthorized modification may
void the equipment authorization from the FCC and will void the BIO-RAD warranty.
This device complies with FCC RF radiation exposure limits set forth for general
population (uncontrolled exposure). This device must be installed to provide a
separation distance of at least 20cm from all persons and must not be collocated or
operating in conjunction with any other antenna or transmitter.

WARNING TO USERS IN THE CANADA / ATTENTION POUR LES
UTILISATEURS AU CANADA
This device complies with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including
interference that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using
an antenna of a type and maximum (or lesser) gain approved for the transmitter by
Industry Canada.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
This device complies with Industry Canada RF radiation exposure limits set forth for
general population (uncontrolled exposure). This device must be installed to provide
a separation distance of at least 20cm from all persons and must not be collocated
or operating in conjunction with any other antenna or transmitter.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux
appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions
suivantes: (1) il ne doit pas produire de brouillage, et (2) l’utilisateur du dispositif
doit être prêt a accepter tout brouillage radioélectrique reçu, même si ce brouillage
est susceptible de compromettre le fonctionnement du dispositif.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio
peut fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur)
approuvé pour l’émetteur par Industrie Canada.
Dans le but de réduire les risques de brouillage radioélectrique à l’ intention d’autres
utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance
isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité nécessaire à
l’établissement d’une communication satisfaisante.
Le présent appareil est conforme aux niveaux limites d’exigences d’exposition RF
aux personnes définies par Industrie Canada. Cet appareil doit être installé afin
d’offrir une distance de séparation d’au moins 20cm avec l’utilisateur, et ne doit pas
être installé à proximité ou être utilisé en conjonction avec une autre antenne ou un
autre émetteur.

MODULE INTEGRATION SPECIAL WARNINGS FOR US & CANADA
• The DTE4027 module is considered as component that will be operated in
combination with the final equipment. Then, the final equipment (including
power supply system) still needs to re-confirm that the whole system complies
with both intentional and unintentional emission requirements.
• We recommend that the minimum 20cm separation distance (for people &
antennas/transmitter) should be mentioned in the end product documentation.
• The end product’s regulatory label should mention:
"Contains FCC ID: 2ABUUDTE4027 and IC: 11658A-DTE4027".
• The motherboard of final equipment where DTE4027 module is to be integrated
must provide a power supply regulation to the module.

3 SYSTEM DESCRIPTION
The hardware is a small PCB which has the following parts:
• RFID antenna coil on the PCB
• RFID chip
• Slave PIC processor for interfacing between the UART commands and the RFID chip
• Red and green LEDs that can be arbitrarily controlled via UART
• Micro-switch that can be read via UART
On the back of the RFID board there is a push-button micro-switch that is connected to two spare inputs
on the slave processor (RA2 and RA3). This can be read via the UART communication.
3.1 Electrical Interface
The RFID connector is a 6-pin Molex PicoFlex 90814-0006.

4 INSTALLATION PROCEDURE
4.1 Installation Requirements
In order to reduce unwanted emission in the spurious domain under the maximum regulatory limits, two
ferrites must be added on the cable connecting the RFID board to the instrument at a distance of 70 mm
maximum from the RFID board connector. The ferrites are mounted as described:
• One ferrite on the power supply wires
• One ferrite on the data and switch wires
• Wires must make a loop one time through the ferrite
• Ferrites must be Würth Elektronik P/N 7427114
4.2 Installation
Install the board with screws using the four holes. The PCB should be covered by an RF permissive
material cover (e.g. plastic).
Power the board with a regulated 5 VDC power supply.
4.3 Command set
The command set is described in the MFPROT_LP.pdf document that can be downloaded from
http://www.ibtechnology.co.uk/pdf/MFprot_LP.PDF. Please refer to this document to control the board.
