There is one function switch to the left of the CREATE button. BSEL0 is
used to set the baud rate of the decoder as described in Figure 10. The
transmitter is set to 4,800bps, so this switch must be in the down position.
The Decoder Board RF Area
Figure 11 shows the RF area of the development board.
This board is populated with the LR Series receiver. The ANT1 connector is
provided for attachment of the included antenna.

The Decoder Board
The decoder board has six main sections of interest: the decoder area, the
RF area, the USB area, the key exchange area, the power supply and the
prototyping area.
The Decoder Area
Figure 9 shows the decoder area of the development board.
The decoder is located in the center beneath the Linx logo. To the left are
LEDs which are connected to the decoder data lines. These light up when
the decoder receives a signal from the encoder to take the data line high.
LED D0 corresponds to data line D0, and so forth.
Beneath the decoder is an LED that is connected to the MODE_IND line.
This lights up as described in the HS Series Decoder Data Guide.
Beneath the LED are three buttons. The one on the left labeled HS_SEND_
KEY is connected to the SEND_COPY line on the decoder. The one in
the middle is connected to the LEARN line, and the one on the right is
connected to the CREATE_KEY line. The HS_SEND_KEY button causes
the decoder to begin sending a copy of its User Data when pressed at the
same time as the LEARN button. The LEARN button is used to learn the
Control Permissions from the encoder and, with the other two buttons, to
make the decoder enter special modes. The CREATE_KEY button causes
the decoder to create a new key when pressed at the same time as the
LEARN button. All of these functions are described in detail in the HS
Series Decoder Data Guide.
