Declaration of Conformity
The KeyDetector DUO has been developed, designed and manu-
factured in accordance with the following EU directive:
R&TTE (99/5/EC)
0408
Version February 2004
KeyDetector DUO Manual and operational description
© SKIDATA AG, February 2004 Page 3
EU countries only: The length of the DC cable (cable between
power adaptor and KeyDetector) must not exceed 3 m.
FCC 15.19:
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 un-
desired operation.
FCC 15.21:
IMPORTANT: Any changes to or modifications of KeyDetector
DUO unless expressly approved by SKIDATA AG, may void the
user's authority to operate this device.
FCC only: the DC cable or combined DC/interface cable must be
fitted with a ferrite element of type “Würth 74271131” near the lo-
cation where the cable connects to the KeyDetector (see image;
the cable must be ‘looped’ twice through the ferrite element, as il-
lustrated below).

KeyDetector DUO KD DUO
KeyDetector DUO is the standard interface module
for SKIDATA’s keymotion technology. As such it
constitutes a connecting link interfacing keycard and
Swatch Access data carriers with higher systems
and applications.
Proximity 122 kHz and 13 MHz transmission
technology.
Reads keymotion Data Carriers; allows coding
them using automatic memory management.
Contains a security-IC for encrypting data for
keymotion data carriers.
Control and communication via serial inter-
face RS232 (RS485 optional) with defined
protocol.
Signalling by red/green/orange LED and
beeper.
Mounting Information
The data transmission between the KeyDetector and
data carriers is sensitive against electrical and electro-
magnetical fields. Those fields are produced by
electrical devices of any kind such as monitors, TV-
sets, ... Thus the KeyDetector must not be placed near
electrical devices. Also metal surfaces placed near the
KeyDetector have a strong impact on the data
transmissions. For sure and reliable operation it is
neccessary that there are no metal objects within 10
cm around the KeyDetector in any direction. If metal
objects are placed between the KeyDetector and a
data carrier data transmission will be impossible at all
in most cases.

External Antenna DUO KeyD ANT DUO
The external antenna can be used in applications
where the KeyDetector with integrated antenna is
not applicable and/or where a second KeyDetector
would be unneccessarily redundant.
