DESCRIPTION
The KH Series is ideally suited for volume use
in OEM applications such as remote control and
command, and keyless entry. Housed in a
compact SMD package, it combines a highly-
optimized RF transmitter with an on-board
encoder. When paired with a matching KH
Series receiver / decoder module, a reliable
wireless link is formed, capable of transferring
the status of 8 parallel inputs over distances in
excess of 300 feet. Ten tri-state address lines
provide 59,049 (3
10
) addresses for security and
uniqueness. No external RF components are
required (except an antenna), making
integration straightforward.
