The FCTN-DEC1-xxx decoder module combines the popular Linx LC series
receiver with a decoder IC and RA series antenna in a convenient through-hole
package. When transmitted data is received, the data is presented to the
decoder. The decoder detects the logic states of the address lines. If these match
with the address settings of the transmitter, the decoders output(s) are set to
replicate the state of the transmitter’s data lines.
The output pins will normally require buffering
due to their low sink or source current
capability. The external addition of a transistor
or other buffer is recommended to provide the
appropriate sink or source current for devices
such as relays, LED’s or motors.
The user must provide a clean source of power
to the module to ensure proper operation.
Power-supply noise will manifest itself as AM
and FM noise and can significantly affect
transceiver performance. Providing a clean
power supply for the module should be a high
design priority. The module’s power-supply line
should have bypass capacitors configured as
shown. Actual capacitor values will vary
depending on noise conditions.
A 1/4 wave antenna such as that employed on the FCTN-DEC1-xxx utilizes the
groundplane as the antenna's counterpoise. In order to achieve the best range
and uniformity, the designer should provide an additional external groundplane.
This can be accomplished in several ways, but a ground fill on the product’s PC
board will generally suffice. The mounting hole beside the antenna must be tied
directly to adequate groundplane no greater than 1/2" away to achieve desired
range.

CONTENTION CONSIDERATIONS
COMPLIANCE REQUIREMENTS (LABELING)
• The following label shall be affixed in a conspicuous location to any device self-
• When the device is constructed in two or more sections connected by wires and
• When the device is so small or for such use that it is not practical to place the
• The label shall not be a stick-on paper label. The label shall be "permanently
certified under the FCC's Declaration of Conformity process, when the product is
authorized based on assembly using separately authorized components and the
resulting product does not require additional testing:
marketed together, the label is required to be affixed only to the main control unit.
statement on the unit itself, the information shown on the label shall be placed in
a prominent location in the instruction manual or pamphlet supplied to the user
or, alternatively, shall be placed on the container in which the device is marketed.
However, the unique FCC logo, device trade name, and model number must be
present on the device.
affixed" to the device (meaning the label is etched, engraved, stamped, silk-
screened, indelibly printed on a permanently attached part of the device or on a
nameplate fastened to the equipment by welding, riveting, or a permanent
adhesive. The label must be designed to last the expected lifetime of the
equipment in the environment in which the equipment may be operated and may
not be readily detachable.
Nine tri-state address lines are provided that allow the selection of up to 19,683
unique identification codes. The address lines are normally attached to a DIP
switch or PCB Jumpers. *Note: Tri-State means the address lines have three
distinct states; high, low, and floating. The data lines will not function unless the
address lines share identical states with the encoder address lines.
An unlimited number of decoder modules may be operated in proximity without
interference. It is important, however, 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.
The FCTN-DEC1-xxx has been tested by an FCC-approved facility and found to
comply will all applicable FCC requirements as of the date, of this document. A
declaration of conformity (DOC) is on file. It is the user’s responsibility to consult
the FCC or other testing body to determine what additional testing may be
required on the user’s completed product. In products where no additional testing
is required, the product may be offered for sale when labeled in the following
manner:
