SETTING THE TRANSMITTER ADDRESS
The Keyfobs are all supplied from the
factory with a default address and all
buttons authorized. The address is
changed by using a paper clip or probe
THE DECODER BOARD
The decoder board included with the evaluation kit uses the LR Series receiver
to receive the signal from the Keyfob transmitter and then feeds it into the MS
Series decoder. The board is designed to allow full access to the many features
of the decoder and to speed development and integration of the LR and MS into
to press the CREATE_ADDR button on
the board through the hole in the back
of the case. When the button is
depressed, a LED will light up in the
MODE_IND window, indicating that the
address is being created. The address
will be randomized for as long as the
button is held down. When the button is

a product. The following sections describe the features of this board in detail.
The Prototyping Area
The prototyping area on the decoder board contains a large area of plated
through-holes so that external circuitry can be placed on the board. This circuitry
can be interfaced with the MS Series decoder through the breakout header to the
right of the holes. At the bottom of this area is a row connected to the 3V power
supply and at the top is a row connected to ground.
released, the randomized address is saved and the LED will begin flashing to
indicate that the Control Permissions may now be set. Press the buttons that the
Keyfob user will have the authority to access. Press the CREATE_ADDR button
with the paper clip again or wait 17 seconds for it to time out. The address and
Control Permissions are now set. The decoder will need to learn the address
before it will accept any transmissions. Please see the Typical Applications
section of this data guide or the MS Series Decoder Data Guide for details.
BUTTON ASSIGNMENTS
The Keyfob is available in five unique button configurations. Those
configurations and the corresponding switch numbers are shown in the figure
below. The table shows which encoder data line has been assigned to each
switch. When a button is pressed, the data line will go high, causing the
corresponding data line on the decoder to go high if the addresses match.
All of the data lines are connected to a wire-wrap header to the right, allowing
easy access from the prototyping area. The Decoder Data and TX ID lines are
also available on the header as well as the PDN line from the RF module. This
allows complete control of the entire system from the prototyping area, giving the
designer a great deal of flexibility in using the board.
The Power Supply
The power supply on the decoder board consists of a standard 9V battery and
power jack connected to a 3.0V voltage regulator. It can provide approximately
500mA of current to the prototyping area, so if the added circuitry will need more
than this, the designer must add an external supply. If the circuit will consistently
draw more than 100mA of current, it might be better to use the power jack rather
than the battery, as the battery may run down fairly quickly, reducing testing and
development time.
The jack accepts a standard 5.5mm plug with the tip ground and the outer shell
7 to 16VDC positive supply. While a reverse voltage protection diode has been
included on the board to protect the circuitry in case the voltage on the plug is

reversed, it is still a good idea to double-check the polarity.
The RF Area
The figure below shows the RF area of the development board. The board uses
the LR Series receiver as shown. Attach the included antenna to the reverse
polarity SMA connector before operation.
