USING THE KEYFOB WITH LINX RECEIVER MODULES
Keyfobs are shipped with all
address lines tied to ground
(Default) with 1024 possible
address combinations available
by cutting address traces.
The Keyfob works directly with
the KH series receiver/decoder
modules when A0-A9 are set
to the same configuration as
the keyfob address lines.
Because the Function Decoder Module
only has 9 address lines, the #9 address
line on the keyfob must be cut. Address
lines 0-8 must match the configuration in
the keyfob for 512 possible addresses.
Also be sure to tie the function decoder's
mounting hole directly to groundplane to
further enhance performance.
The LC receiver module can be used
with an appropriate decoder such as
Holteks HT-658 for 1024 possible
addresses.
