CMD HHTX is” Brannon Handheld Transmitter
Home / Industrial Automation CMD HTX-ASS B-Bunori Handheld Transmitter
Wire Elimination ‘ : Standard Frequency
BATTERY REPLACEMENT
THEORY OF OPERATION
The CMD-HHTX-XXX Remote Command Unit combines the popular Llnx LC
series transmitter and “Spiatch” planar antenna with a commonly available
encoder IC to Iorm a simple yet ettective RF remote control transmitter, The
products operation is straightlonrvard. 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 Iormatted into a 3-Word transmission cycle which
continues until the button is released The encoder data is used to modulate the
LC transmitter which through the antenna conveys the data into Iree space. The
transmitted signal may be received by any Linx LC receiver or pre~made function
module. Once data is received it is decoded usrng a decoder to or custom
microcontroller. The transmitted address bits are checked against the address
settings oi the receiving device. Ila match is confirmed, the decoders output(s)
are set to replicate the transmitter‘s button status.
SETTING THE TRANSMITTER ADDRESS
In order to allow the formation of
up to 256 unique Transmitter-
Receiver relationships. the
transmitter’s address may be
selected using internal DIP
switches as shown. The switches
are accessed by remoVing the
rear cover as tor battery
replacement.
ADDRESS
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 ol encoded digital
data. only one carrier of any Irequency can occupy airspace without contention
at any given time,
The remote unit utilizes a CIR-2032 Button
Lithium Cell. In normal use it Will provide 1-2
years of operation. Access ior replacement is
accomplished by removing the screw in the
middle of the back cover. Once the unit is open,
remove the battery by depressing the release
finger on the battery holder as shown. Replace
the cell With the same type While observing the
polarity shown.

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 Flutes. 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 equtpment into an outlet on a circuit different from that to
Wthh 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 ln order to maintain
complrance 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 receptionThe
user IS cautioned that changes and modifications made to the
