FCTN-RLY4-418

Page 7Page 6 Page 7
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.
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.
COMPLIANCE REQUIREMENTS
The FCTN-RLY4-***-2 has been tested by an FCC-approved facility and been
found to comply with all applicable FCC and Industry Canada 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 if any
additional testing may be required on the user’s completed product. In products
where no additional testing is required, further labeling of the unit is not needed
unless the module will be placed inside another housing. It is, however,
necessary to include the following statement in the end product’s instruction
manual or insert card.
Place the above statement in the instruction manual or insert card.
LABELING REQUIREMENTS
In cases where the FCTN-RLY4-***-2 module is incorporated inside a product
and its standard labeling is not visible, the end product must be labeled as shown
below.
The following label shall be affixed in a conspicuous location to any device
self-certified under the FCC’s Declaration of Conformity process:
When the device is constructed in two or more sections connected by wires
and marketed together, the label is required to be affixed only to the main
control unit.
The label shall not be a stick-on paper label. The label shall be “permanently
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.

TRANSMITTERS
The Relay Function Module incorporates a Linx LR Series receiver paired with a
Holtek-based decoder IC. This means that there are several options available for
controlling the module.
The first option is to use one of the
pre-certified OEM transmitters offered
by Linx. These transmitters come in
several packages and can be
customized to bear the logo or other
artwork required by the customer. The
only setup required by the customer is
to set the address of the transmitter
and the Relay Module.
There are four OEM transmitters that
can be used with the Relay Function
Module: the Full Size Handheld, the
Compact Handheld, the Long-Range Handheld, and the Keyfob. The Full Size
Handheld uses the same eight address lines used by the Relay Function
Module, so they only need to be set the same for proper function.
The other three transmitters use all ten address lines offered by the Holtek ICs
while the Relay Function Module uses eight. This means that the last two
address lines on the transmitters (A8 and A9) must be left floating (turn off the
DIP switches on the handhelds, cut traces 8 and 9 on the Keyfob). The other
address lines can be set to whatever the user desires, as long as the transmitter
and the Relay Function Module match.
A custom transmitter can also be created with a KH2 Series transmitter or an LC
or LR Series transmitter paired with a Holtek HT640 encoder or microprocessor.
Because the Holtek ICs have 10 address lines, the last two lines (A8 and A9)
must be left open. The Holtek address lines are tri-state, meaning that they have
three valid input conditions: high, low, or floating. The Relay Function Module
uses only the low and floating states, so the custom transmitter can only use
these states as well. The lines that are floating should be left open and have no
electrical connection.
It should be noted that the Keyfob
transmitter does not allow full
functionality of the Relay Function
Module. Each of the four relays in
the module uses two data lines for a
total of eight. The Keyfob transmitter
offers a maximum of five buttons, so
at most, it can control two relays in
latched operation and three in
momentary operation.
Application Note AN-00300
describes in detail how to set the
Relay Function Module address to
match any of the Holtek-based transmitters offered by Linx. This note can be
found in the Support section of the Linx web site, www.linxtechnologies.com.
