TYPICAL APPLICATIONS

The signal sent by the MS Long-Range Transmitter can
be received by an LR Series receiver module or the LT
Series transceiver module. The outstanding sensitivity
of the LR Series receiver offers the best range when
used with a Linx OEM transmitter. The receiver module
is then connected directly to an MS Series decoder,
which will decode the transmitted signal.
When a button is pressed on the transmitter, a
corresponding line on the decoder will go high. This can
then be connected to external circuitry to perform
whatever function is required by the application.
The decoder must learn the transmitter’s address
before they can work together. This is done by taking
the LEARN line on the decoder high, typically with a
pushbutton switch. The MODE_IND line will start switching (if a LED is attached,
this will cause it to flash) indicating that the decoder is in Learn Mode. Press any
of the buttons on the transmitter to initiate a transmission. Take the LEARN line
high again to exit Learn Mode and the system will be ready for use. The figure
below shows a schematic for a typical application.
The MS Long-Range Transmitter
is
SEL_BAUD0 should be tied high
and SEL_BAUD1 tied low.
The decoder has several unique
features, such as Latch Mode,
Receiver Control, and TX_ID.
If the LATCH line is tied to V
the outputs will go high on the
first transmission, then low on
the second. Figure 6 shows it
tied low, so the outputs will be
momentary (high for as long as a
signal is received that instructs
the decoder to make them high).
The RX_CNTL line can be
connected to the PDN line of the
receiver and the decoder will
activate the receiver with a 10%
duty cycle This greatly reduces
the average current consumption
of the system. The adjacent figure shows it tied to ground, but to use this feature,
connect the RX_CNTL line of the decoder directly to the receiver’s PDN line.
The TX_ID line will output a number associated with the originating transmitter /
encoder. Application Note AN-00156 shows how to use this feature.
Data guides for the receivers, the MS encoder, and the MS decoder can be
found on the Linx Technologies website at www.linxtechnologies.com.
