OEM COMPACT HANDHELD TRANSMITTER DATA GUIDE
CMD-HHCP-xxx
DESCRIPTION
The Linx HHCP Remote Command
Unit is ideal for general-purpose
remote-control and command appli-
cations.This unit has been precertified
for FCC Part-15 compliance which
reduces costs and time to product
introduction. Available in 315, 418 or
433.92MHz (418MHz standard), this
compact handheld remote is capable
of up to 150 ft. transmission range.The
transmitter unit can be configured with
1-8 buttons and the keypad and
labeling can be modified to meet
specific customer requirements.
Selectable addressing provides
security and allows the creation of up
to 1024 distinct transmitter-receiver
relationships. The transmission can be
decoded using a matching Linx
function module, KH-Series Module, or
a Linx LC-Series receiver paired with a
decoder IC or microcontroller. The unit
operates from a single 3-volt lithium
cell.

THEORY OF OPERATION
The CMD-HHCP-xxx Remote Command Unit combines the popular Linx LC-
Series transmitter with an internal Splatch antenna, and a commonly available
encoder IC to form a simple yet effective RF remote-control transmitter. When a
button is activated 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
DIP-switch address and button data lines.These states are then formatted into a
3-word transmission cycle which 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. The transmitted signal may be received by any
Linx LC- or KH-Series receiver or pre-made function module. Once data is
received, 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 output(s) are set to replicate the transmitter’s
button status.
SETTING THE TRANSMITTER ADDRESS
In order to allow the formation of
up to 1024 unique Transmitter-
Receiver relationships, the
transmitter’s address may be
selected using internal DIP
switches as shown.The switches
are accessed by removing the
DIP-switch access cover.
CONTENTION CONSIDERATIONS
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 frequency can occupy airspace without contention
at any given time.
BATTERY REPLACEMENT
The remote unit utilizes a CR-2032 Button Lithium Cell.
In normal use it will provide 1-2 years of operation.
Access for replacement is accomplished by removing the
battery 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. Replace the
cell with the same type while observing the polarity
shown.

COMPLIANCE REQUIREMENTS
The CMD-HHCP-xxx has been pre-certified by Linx for FCC Part-15 compliance
when used with an appropriate function module in keeping with the applications
allowed under section 15.231.
LABELING/INSTRUCTION REQUIREMENTS
The CMD-HHCP-xxx Remote Command Unit has already been labeled in
accordance with FCC 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.
INSTRUCTION TO THE USER
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.
Place the above statement in the instruction manual or insert card.
