TYPICAL APPLICATIONS
The signal sent by the HS 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 HS Series decoder, which will
decrypt 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 transmitter and decoder must be synchronized
before they can work together. This is done by creating
a new encryption key in the decoder, then transferring it
RXM-***-LR
LICAL-DEC-HS001
to the transmitter as previously described.
The adjacent figure shows a schematic for a typical receiver application. The
handheld transmitter is set to 4,800bps, so the decoder’s SEL_BAUD line will
need to be tied low.
The decoder has several
unique features, such as Send
Copy, and TX_ID.
As the name suggests, “Send
Copy” allows the users and
