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
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
unique features, such as Send
Copy, and TX_ID.
As the name suggests, “Send
Copy” allows the users and
associated Control Permissions
of one HS Series decoder to be
transferred to another. This is
useful if the same users and
permissions are desired at
multiple locations, such as the
front door and back door of a
building. Please see the HS
Series Decoder Data Guide for
more
feature.
The TX_ID line will output a
number associated with the
handheld transmitter from which the signal originated. Linx Application Note AN-
00156 shows how to use this feature.
Data guides for the LR Series receiver, the HS encoder, and the HS decoder can
