compliance,
reducing
development costs and time to market.
Available in 315, 418 (standard), or
433.92MHz, this stylish and compact remote
has a range of up to 750 feet when combined
with the LR Series receiver. The Keyfob can
be configured with 1 to 5 buttons and the

addressing provides security and allows the
creation of up to 1,024 distinct transmitter-
receiver
relationships.
The
Keyfob
is
available in black, white, or translucent
colors. The transmission can be decoded
using a matching Linx Function Module, KH
Series receiver / decoder, or an LR or LT
Series receiver paired with a decoder IC or
microcontroller. The unit operates from a
single 3V CR2032 lithium button cell.

    ... Notes 1. Characterized, but not tested THEORY OF OPERATION The CMD-KEY#-*** Keyfob transmitter combines the LR Series transmitter with an on-board Holtek HT640 encoder IC to form a simple, yet effective, RF remote control transmitter. The LR transmitter is a low-cost, high-performance, synthesized ASK / OOK transmitter. The transmitter’s synthesized architecture delivers outstanding stability and frequency accuracy while minimizing the effects of antenna port loading and mismatching ...
