THEORY OF OPERATION
The FCTN-WALL-*** module combines
the popular Linx LR Series receiver with a
decoder and high quality switching relay.
When transmitted data is received, the
data is presented to the decoder. The
decoder detects the logic states of the DIP
switch address lines, and if these match
the address settings of the encoder, the
decoder’s outputs are set to replicate the
state of the encoder’s inputs. In the AC
Function Module, the data lines are also
compared to the settings of four control dip
switches that determine which transmitter
buttons or data lines will be accepted. The
relationship is shown in the adjacent chart.
If the DIP switch labeled Button 1 is turned
on, then when data line D6 on the decoder
goes high, the AC Function Module will
activate and apply power to the output.
When line D7 goes high, the module will
turn off. As long as the other button
switches are turned off, the module will
ignore all of the other data lines. If multiple DIP switches are turned on, then the
module will be controlled by multiple buttons or data lines. For example, if
switches 1 and 2 are on, then lines D6 and D4 will switch the AC Function
Modules output on and lines D7 and D5 will turn it off.
SETTING MODULE ADDRESS
The AC Function Module provides a total of sixteen unique address settings.
Address selection is made via the bottom four DIP switches on the module. In
order for the encoded commands sent by the transmitter to be recognized, the
address settings of the transmitter and receiver must match exactly.
CREATING UNIQUE GROUPS
The four control DIP switches can be used to create distinct groups of AC
Function Modules that can all be operated by a single command unit. For
example, any number of AC Function Modules can be set to a single address
and be controlled by one of the button pairs (ON / OFF) on a command unit. You
can also set up different banks using up to sixteen AC Function Modules, each
set to a different address. Please read the Contention Considerations section
when using multiple transmitters in close proximity.
EQUIPMENT CONNECTION
Each AC Function Module is designed to switch AC loads of up to 1,800 watts.
Plug the AC Function Module in, then plug the equipment to be switched into the
receptacle on the face of the unit. More than one device can be connected with
the addition of a power strip; however, the total draw of all connected equipment
must never exceed the unit’s 1,800W rating.
