The MS Long-Range Handheld
Transmitter allows the selection of one
of 16,777,216 (2 24 ) unique addresses.
All transmitters are supplied set to the
same address. To avoid contention with
other units or to create unique
relationships, the address can be
changed. This is accomplished by using
a paper clip or probe to press the
CREATE button on the board through
the hole in the back of the case. Press

THEORY OF OPERATION
The OTX-***-HH-LR8-MS Long-Range Handheld Transmitter combines an LR
Series transmitter and an antenna with an on-board MS Series encoder to form
a simple, yet highly reliable RF remote-control transmitter. The LR Series
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. This reduces or eliminates frequency pulling, bit contraction, and
other negative effects that are common to SAW-based transmitter architectures,
providing a significantly higher level of performance and reliability.
When a button is pressed on the transmitter, power is applied to the internal
circuitry and the encoder is enabled. The encoder then detects the logic states
of the button data lines. These states are formatted into a 2-word transmission
cycle which continues until the button is released. The encoder data is used to
modulate the transmitter which conveys the data into free space through the
antenna. Once data is received, a decoder IC is used to check the transmitter’s
button is held down. Release the button and the randomized address will be
saved and the LED will begin flashing to indicate that the Control Permissions
may now be set. Press the buttons that the transmitter will have the authority to
access. Press the CREATE button with the paper clip again or wait 17 seconds
for it to time out. The address and Control Permissions are now set. The decoder
will need to learn the address before it will accept any transmissions. Please see
the Typical Applications section of this data guide or the MS Series Decoder
Data Guide for details.

address against an address saved in memory. If a match is confirmed, the
decoder’s outputs are set to replicate the transmitter’s button states. These
outputs can then be used to activate external circuitry required by the
application.
The transmitter is compatible with the LT and LR product families. For
applications where range is critical, the LR Series receiver is the best choice due
to its outstanding sensitivity. When the transmitter is combined with an LR Series
receiver and an MS Series decoder, ranges of up to 1,000 feet are possible.
Applications operating over shorter distances will also benefit from the increased
