THEORY OF OPERATION
The CMD-HHLR-xxx Remote Command Unit combines the LR Series
transmitter and an antenna with an on-board Holtek HT640 encoder IC to form a
simple, yet highly reliable, 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. 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 remote unit, power is applied to the internal
circuitry and the encoder IC is enabled. The encoder then detects the logic states
of the address lines and button data lines. These states are formatted into a
three-word transmission cycle that continues until the button is released. The
encoder data is used to modulate the transmitter, which, through the antenna,
conveys the data into free space. On the receiver side, a decoder IC or custom
microcontroller is used to check the transmitter's address bits against the
address settings of the receiving device. 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 several Linx receiver products, including the
LC, LR, KH, and OEM 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 the HT658 decoder
chip, ranges up to 1000 feet are possible. Applications operating over shorter
distances will also benefit from the increased link reliability and superior noise
immunity provided by the LR Series receiver.
The Long Range Hand Held transmitter
allows the selection of one of 1024
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
using internal DIP switches as shown.
The switches are accessed by removing
the DIP switch access cover on the back
of the transmitter.

A1 = 2
A2 = 3
A3 = 4

If the switch is on, the address line is Figure 2: DIP Switch Assignments
connected to ground, otherwise it is
floating. The receiver's address must match exactly in order for the units to
communicate. Application Note AN00300 describes in detail how to set the
address to match any of the receivers offered by Linx. This note can be found in
the Support section of the Linx web site, www.linxtechnologies.com.

CONTENTION CONSIDERATIONS
COMPLIANCE REQUIREMENTS
It is important to understand that only one transmitter at a time can be activated
within a reception area. While the transmitted signal consists of encoded digital
data, only one carrier of any particular frequency can occupy airspace without
contention at any given time. If two transmitters are activated in the same area
at the same time, then the signals will interfere with each other and the decoder
will not see a valid transmission, so it will not take any action.
INSTRUCTION TO THE USER
Battery Access
This device complies with Part 15 of the FCC Rules.

The outstanding sensitivity of the
LR Series receiver offers the best
range when used with the Hand
Held transmitter. When using the
LR Series receiver, the Holtek
HT658 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. If the
address lines match, when a button
on the transmitter is pressed a
corresponding data line on the
decoder (D0-D7) will go high.
These data lines can then be
connected to external circuitry to
perform whatever function is
required by the application.

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 or the AC
Wall Module. These items are also pre-certified and
can be immediately included in a product.
