RECEIVERS
There are four options for receivers within the Linx
product line. The first option is to use one of the OEM
Function Modules, such as the Relay Module or the AC
Wall Module. These items are also pre-certified and
can be immediately included in a product.
The other options are to use one of the Linx receiver
modules. The signal sent by the Keyfob transmitter can
be received by the LR Series receiver module or the LT
Series transcever module. These modules can be
connected to the Holtek HT658 decoder to decode the
signal, or a custom microcontroller can be programmed
to decode it and take specific action.
The KH2 Series offers a slightly simpler solution by
combining the LR Series receiver and the HT658
decoder in a single package.
When a button is pressed on the transmitter, a
corresponding line on the decoder will go high (as long
as the addresses match). This can then be connected
to whatever circuitry is required by the application.
Application Note AN-00300 discusses in detail how to
set the addresses on all of the units. Data guides for all
of the receivers, the HT640 encoder, and the HT658
decoder can be found on the Linx Technologies
website, www.linxtechnologies.com.
TYPICAL APPLICATIONS
The outstanding sensitivity of the LR
Series receiver offers the best range
when combined with the Keyfob
transmitter. When using the LR
Series receiver, the Holtek HT658
decoder chip should be connected
to decode the received signal. This

be hardwired. As long as the
address lines match, when a button
on the Keyfob is pressed, a
corresponding data line on the
decoder (D0-D4) will go high. These
data lines can then be connected to
