• Each keypad connection on the back panel of the CAi-Series Master
Controller corresponds to the room / zone number chosen for your
speakers. Each zone operates independently, so it is very important to
connect the keypad to the correct zone keypad input.
• On List 4 (opposite) copy down the room name to the zone number
from List 3 on pg 6. NOTE: the keypad and the speakers in each room
must be hooked to the corresponding numbered zone.
WIRING AT THE CONTROLLER
CAi System keypads are wired with CAT-5 wire. It is inexpensive and color coded for ease of installation. Due to the
qualities of CAT-5 wire, when using it for keypad control
wire with the CAi-Series, it is recommended to use the following color code for maximum performance. NOTE: 250ft

INSTALLING THE KEYPADS
• The best infrared remote performance is achieved with
the keypad away from any direct sunlight. Also consider
convenience when choosing a location.
• Choose a place that is easily seen from the position where
a person is most likely to be located.
• Check whether or not you can route the wire to the location you have chosen.
• Purchase retro-fit plastic junction boxes (min. 18 cubic
inches) or p-rings and cut in the boxes using a key-hole
saw or sheetrock knife/hand saw.
• If you are installing the optional DSC keypad you will
need to use a double-gang electrical box. If you are
installing both the optional DSC and DAN keypad you
will need to install a triple-gang electrical box.
• If you feel uncomfortable cutting into your walls and
running wire through the walls, seek help from a professional installer or an electrician.
• Route the wire to the junction box from the CAi location.
• If using 22 AWG wire, connect each wire to the correct
position 1 thru 8 using the included punchdown tool.
Refer to List 5.
• If using CAT-5 wire, connect each wire to its corresponding color labeled on the punchdown terminal.
• Mount the keypad in the junction box and attach the
Decora© plate.
•The CA-KP2 keypad has source labels for your convenience. Insert the label in the keypad keeping the input
number in sequence with the source selected.
• Repeat the above steps until all keypads are installed.

OPERATING THE CA-LCD2 KEYPAD
OPERATION
1) Display: The LCD panel displays the name of the source
selected and the volume level.
2) Source: The source button is pressed to select one of the
four sources to listen to. Press the source button until the
desired source is selected. The source will be displayed on
the LCD display panel.
3) Volume Up / Down: The UP / DOWN arrows for volume
are used to select the volume level and to select a different source name after the store button is pressed. If the
button is pressed and held the volume will ramp up or
down.
4) Lamp: The lamp button when pressed and released will
turn on and off the backlight lamp. The backlight color
can be set to amber or green by pressing and holding the
button. The backlight will change from one color to the
other.
5) Power: Turn on or off any zone by pressing the power
button on the front of the corresponding keypad. When
the keypad comes on, it will automatically select the
source that was previously selected and set the volume to
minimum.
6) Store: The store function is used to select and store one
of the 23 preset source names for each of the four
sources. Select the source name that you want to change
by selecting source. Press and hold the store button for
approximately 3 seconds, and the display begins to flash.
Immediately press the UP/ DOWN volume buttons to
select the different source names. After you have selected
the name, press the store button again or wait for it to
stop flashing.
7) IR Receiver: The IR receiver is used to receive commands
from an IR remote control. Remote controls used for the
source equipment will pass through to the main controller and on to the source equipment. It will receive IR
signals from 38KHz to 56KHz. To control the functions of
the keypad, use the CAi Remote control (see Figure 20).
The CAi remote control will operate the lamp, source
selection, volume up / down and room on / off.
8) IR Confirmation LED: This LED will flash to confirm the
reception of an IR signal from a remote control through
the IR receiver.

TROUBLESHOOTING
KEYPAD WIRING PROTECTION CIRCUIT
To provide protection for incorrect keypad wiring, this CAiSeries product is equipped with a short circuit protection
device. In the event of a keypad cable short, or incorrect
keypad wiring, this device will automatically interrupt power
to all keypad ports.
Once installed, if the keypads connected to your CAi-Series
product will not turn on, the short circuit protection device
may have been activated. Please take the following steps to
troubleshoot the system.
1) Turn off the power switch on the front of the CAi-Series
controller.
2) Disconnect all keypad connections from the rear of the
controller.
3) Check the wiring configuration for each keypad, checking
both ends (the CAi unit and the CA keypads) of the CAT-5
keypad cable.
4) If incorrect connections were found, correct the wiring
and reconnect the keypads to the controller. After the
controller has been powered off for at least 15 seconds,
turn on the power switch of the CAi-Series controller.
5) If the problem persists, repeat steps above trying each
keypad consecutively.
6) Inadequate ventilation can allow normal heat to build up
and trip the protection circuit.

ELIMINATION OF BALANCE LINE
The following diagram shows how resistors may be used at
the Keypad connection on the rear of the CAi master control
unit, to provide 2.5VDC to the balance control line for centering. This circuit will stabilize the balance line input and
keep it centered. They can be used to free up one of the 8
required conductors if one is open, shorted or if an extra
conductor is needed for a secondary IR receiver’s signal in
that zone. Position #7 is GND, #2 is 12VDC, #4 is Balance.

COMBINING ADDITIONAL IR RECEIVERS
When combining a CAi Series multi-source controller and a
secondary IR system together, it needs to be done after the
CAi System. The IR information from the keypad is on Pin
#2. This signal is demodulated at the keypad and is re-modulated at the processor then sent to the emitter out-puts.
Combining a modulated IR signal to this lead (#2) will not
work because it is already modulated. The following method
should be used to assure correct integration with such components.
Simply plug the IR linking cable supplied with the CAi product into the IR “Link Out” jack on the CAi and plug the other
end into the Russound 857 IR Connecting Block’s “IR
Common In”. The secondary IR receiver can either be wired
to the terminal block as shown or plugged into the “IR
Reciever In” via an 1/8” mini-plug. The emitters that would
have been connected directly to the CAi system will now be
plugged into the connecting block.
This method combines the modulated IR signal at the connecting block then distributes it to the six emitter ports.
