DS102-9
Power Supply
The circuit has been designed to operate from a single PP3 battery supply. This will provide in excess of
1,000,000 transmissions.
Note: reverse voltage polarity connection may cause damage to the circuit.
License Exemption (Radio Transmitters)
Europe: The transmitter encoders use ECM compliant radio transmitter modules and complies with
ETSI330-220 and ETSI300-683.
USA: This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
KEELOQ Protocol Configuration
Each encoder is supplied ready programmed with a unique random serial number. The decoder has the
ability to memorise this serial number using a simple learn procedure (please see decoder datasheet).
How does KEELOQ technology work?
KEELOQ is based on a code hopping algorithm which provides Rock Solid Security. KEELOQ uses
a programmable 64-bit encryption key that is unique to each device to generate 32-bit hopping
code. The key length and hopping code combination reduces the possibility of unwanted access,
due to code grabbing and code scanning, to essentially zero. Such CIA-like levels of security are
desirable, but many manufacturers would expect them to be cost-prohibitive. KEELOQ offers the
solution for affordable, Rock Solid Security that is the future of technology for the cars, homes and
offices we wish to protect.
Adding Additional Switches
Additional switches may be added through Connector J3. The four connections of J3-1, 2, 3, & 4
represent the four input lines to the HCS360 encoder device. These may be connected to a binary coded
decimal (bcd) input to obtain 1 of 16 states.
In addition to this, J3-7 = 5Vdc and J3-8, 9, 10 = GND.
