THE DECODER BOARD (CONT.)
The Decoder Area
The figure below shows the decoder area of the development board.
Figure 5: The Decoder Area
The decoder is in the center beneath the Linx logo. To the left are LEDs that are
connected to the decoder data lines. These will light up when the decoder
receives a signal from the transmitter instructing it to take the data line high. LED
D0 corresponds to data line D0 and so forth.
Beneath the decoder are two LEDs. D12 is connected to the MODE_IND line.
D8 is connected to the RX_CNTL line and will provide visual feedback by lighting
up when the decoder activates the receiver when in RX Control Mode.
Under the LEDs is a button that is connected to the LEARN line. This button is
used to learn the Code Word from the encoder as described in the MS Series
Decoder Data Guide.
There are four switches to the left of the CREATE / LEARN button. BSEL0 and
BSEL1 are used to set the baud rate of the decoder as shown in the chart below.
The Long-Range Handheld Transmitter is set to 9,600bps, so BSEL0 should be
THE DECODER BOARD (CONT.)
The USB Area
The decoder board has a Linx SDM-USB-QS-S USB module for use with the
included development software. This module is powered by the USB bus, so it
will not pull any current from the battery. The figure below shows this section.
Figure 6: The Decoder Board USB Area
The microcontroller on the right monitors the data lines and generates
commands that are sent to the development software on the PC via the QS
Series USB module. The RX_IND LED to the left of the module will flash to
indicate that data is being received from the PC, and the TX_IND line will flash
to indicate that the module is sending data to the PC.
The QS Series USB module provides a simple serial link to a PC via a USB
connection. It converts logic-level serial signals to USB-compliant signals and
vice versa, so it can be connected to virtually any serial device, including
microcontrollers, RS-232 / RS-485 level converters, or Linx RF modules. It is
completely self-contained, requiring only a USB type B jack, and includes all
necessary firmware and drivers.
on and BSEL1 should be off. If the
switch is up, then the line is high
(on); if down, the line is low (off).
*Important* The decoder board must be
set to the same baud rate as the
transmitter in order for the signal to be
received correctly.

The PDN switch will connect the RX_CNTL line of the encoder to the PDN line
of the receiver so that the RX Control Mode can be tested. This mode is
described in the MS Series Decoder Data Guide.
When on, the LATCH switch will place the decoder into Latch Mode, so that the
data lines will go high when a valid signal is received and stay high until a second
valid signal is received. If the switch is off, the data lines are momentary.
