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. 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 transceiver module. These modules can
be connected to the DS Series decoder to decode the
signal, or a custom microcontroller can be programmed
to decode it and take specific action.
Typical Applications
The outstanding sensitivity of the LR Series receiver offers the best range
when used with the Handheld transmitter. When using the LR Series
receiver, the DS Series decoder chip should be used to decode the
received signal. This decoder has ten address lines that must match the
transmitter address lines. A DIP switch is commonly used to set these,
but they can also be hardwired. As long as the address lines match, when
a button on the transmitter is pressed, a corresponding data line on the
decoder (D0–D7) goes high. These data lines can then be connected
to external circuitry to perform whatever function is required by the
application.
Figure 11 shows a typical schematic using the LR Series receiver and the
DS Series decoder.
ANTENNA
The KH2 Series offers a slightly simpler solution by
combining the LR Series receiver and the Holtek
decoder in a single package. This receiver only
supports the Holtek protocol, not the serial protocol.

When a button is pressed on the transmitter, a corresponding line on the
