OEM COMPACT HANDHELD TRANSMITTER DATA GUIDE
DESCRIPTION
The CMD-HHCP-***-xxx Compact Handheld
transmitter is ideal for general remote control
and command applications. As a part of our
R 0.2"
Holtek encoder-based OEM family, it has
been pre-certified for FCC Part 15, Industry
2.00"
Canada, and European CE (433MHz only)
2.81"
compliance, reducing development costs and
time to market. Available in 315, 418
(standard), or 433.92MHz, this compact
remote has a transmission range of up to 750
feet when combined with the LR Series
receiver. The transmitter unit can be
configured with 1 to 8 buttons and the keypad
and labeling can be modified to meet specific
OEM customer requirements. Selectable
addressing provides security and allows the
creation of up to 1,024 distinct transmitter-
receiver relationships. The address can be
easily changed via an externally accessible
DIP switch. The transmission can be
decoded using a matching Linx Function
Module, KH2 Series receiver / decoder, or a
Linx LR or LT Series receiver paired with a
decoder IC or microcontroller. The unit uses
a single 3V CR2032 lithium button cell.

exactly in order for the units to communicate. Application Note AN-00300

BUTTON ASSIGNMENTS
THEORY OF OPERATION
This diagram illustrates the relationship between the button locations and
encoder data lines.
The CMD-HHCP-*** Compact Handheld transmitter combines the LR Series
transmitter with an internal Splatch Series antenna and 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 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 IC is enabled. The encoder 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
LR, KH2, LT, 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 of up to 1,000 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.

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.
The CMD-HHCP-*** has been pre-certified by Linx Technologies for FCC Part
15 and Industry Canada RSP-100 compliance. The 433.92MHz version has also
been tested for CE compliance for use in the European Union. The 315MHz and
418MHz versions are not legal for use in Europe.
LABELING / INSTRUCTION REQUIREMENTS
The CMD-HHCP-*** Compact Handheld transmitter has already been labeled in
accordance with FCC, Industry Canada, and CE regulations in effect as of the
date of this document. No further labeling of the unit is needed; however, it is
necessary to include the following statement in the end product’s instruction
manual or insert card for FCC compliance. Industry Canada only requires the
shaded portion. EU does not require a statement.
BATTERY REPLACEMENT
The remote unit utilizes a standard CR2032 lithium
button cell. In normal use, it will provide 1 to 2 years of
operation. To replace the battery, remove the access
cover by pressing down firmly on the label area and
sliding it off. Once the unit is open, remove the battery
by sliding it from beneath the holder.

INSTRUCTION TO THE USER
There may be the risk of explosion if the battery is
This device complies with Part 15 of the FCC Rules.
Operation of this device is subject to the following two conditions:
(1) This device may not cause harmful interference, and
replaced by the wrong type. Replace it with the same
type of battery while observing the polarity shown in
the adjacent figure.
Battery Access

(2) This device must accept any interference received, including interference
that may cause undesired operation.
ASSEMBLY DIAGRAM
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of
the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This equipment has been certified to comply with the limits for a Class B
computing device, pursuant to FCC Rules. In order to maintain compliance with
FCC regulations, shielded cables must be used with this equipment. Operation
with non-approved equipment or unshielded cables is likely to result in
interference to radio and TV reception. The user is cautioned that changes and
modifications made to the equipment without the approval of manufacturer
could void the user’s authority to operate this equipment.

RECEIVERS
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.
The other options are to use one of the Linx receiver
modules. The signal sent by the Compact Handheld
transmitter can be received by the LR Series receiver
module or the LT Series transcever module. These
modules can be connected to the Holtek HT658
decoder to decode the signal, or
a
custom
microcontroller can be programmed to decode it and
take specific action.
The KH2 Series offers a slightly simpler solution by
combining the LR Series receiver and the HT658
decoder in a single package.
When a button is pressed on the transmitter, a
corresponding line on the decoder will go high (as long
as the addresses match). This can then be connected
to whatever circuitry is required by the application.
Application Note AN-00300 discusses in detail how to
set the addresses on all of the units. Data guides for all
of the receivers, the HT640 encoder, and the HT658
decoder can be found on the Linx Technologies
website, www.linxtechnologies.com.

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. As long as 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.
