• Check the battery to make sure it is not dead.
• Make sure that the baud rate switches are set the same on both boards.
• Make sure that the antenna is connected.
• Check to see if the PDN switch is on, placing the encoder and decoder into

After unpacking the development system, attach an antenna to each board,
install the supplied 9V battery, and turn on the power switches. The encoder and
decoder will be set at the factory and will work straight out of the box. To create
a new operational setup, follow these steps:
If the boards fail to work out of the box, then try the following:

THE PROTOTYPING AREA
THE POWER SUPPLY
Figure 3: The Prototyping Area and Power Supply
The prototyping area is the same on both boards and 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 HS encoder or decoder through the breakout
header to the right. 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.
All of the data lines are connected to a wire-wrap header to the right, allowing
easy access from the prototyping area. The DATA_IN, DATA_OUT, and TX_ID
lines are also available on the header, as well as the PDN lines from the RF
modules. This allows complete control of the entire system from the prototyping
area, giving the designer a great deal of flexibility in using the boards.
The power supply is the same on both boards and consists of a standard 9V
battery and a power jack connected to a 3.0V voltage regulator. The regulator
can provide approximately 500mA of current to the prototyping area. If the added
circuitry will need more than this, then 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, 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. A reverse voltage protection diode has been
included on the board to protect the circuitry in case the voltage on the plug is
reversed, but it is still a good idea to double-check the polarity.
