THE DECODER BOARD (CONT.)
The Decoder Board Key Exchange Area
The figure below shows the key exchange area of the development board.
The Prototyping Area
The prototyping area 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 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 decoder DATA_IN and TX_ID lines
are also available on the header, as well as the PDN line from the receiver. This
allows complete control of the entire system from the prototyping area, giving the
designer a great deal of flexibility in using the boards.
Figure 9: The Decoder Board Key Exchange Area
The key is created in the decoder and transferred to the transmitter with an
infrared (IR) link. This consists of an infrared diode (IR2) that is modulated by the
KEY_OUT line of the decoder and an infrared receiver built into the transmitter.
Once the key is created, the decoder will begin to output the key information
through this circuit. The clear plastic window on the back of the transmitter
should be held within a few inches of the infrared diode and the key transfer will
happen automatically. Jack J4 is also connected to the KEY_OUT line and is
available for wired transfer of the key, but the handheld transmitter is not adapted
to accept a wired connection. The rest of the circuitry is used for sending and
receiving copies of the decoder’s User Data, as described in the HS Series
Decoder Data Guide, but is not required for operation of this development
system.
The Power Supply
The power supply 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 will 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.
