Product Overview
The CA 6.4 LRN Keypad is an accessories to the CA-Series Multi-Zone
Control Systems. The LRN connects to the CA KP Keypad via a 16 pin
ribbon cable, connected to the back side of the keypad. The LRN adds the
ability to store and remotely activate infrared commands of virtually any
IR-controlled device connected to a CA Multi-Zone System. Infrared
commands can be stored into the LRN Keypad through a simple
programming procedure. Commands are executed by simply pressing the
command keys to which the infrared commands were previously stored.
There are 12 command keys on the front face of the keypad. The LRN has
a total of 4 control layers which allows control of up to 4 infrared-
controlled devices. A total of 48 infrared commands can be stored and
executed by the LRN Keypad.
Connection Instructions
1) Read the KP Keypad Wiring Instruction section of the CA6.4 Multi-
Zone Controller manual, as well as the section on the infrared emitter
outputs.
2) Turn off the CA-Series Multi-Zone Controller.
3) Connect the CA6.4 LRN's Interface cable to the 16 pin header located
on the CA6.4 KP Interface. Note the location of the red stripe.
4) Connect the KP Keypad to the corresponding keypad input of the CA-
Series Multi-Zone Controller, as shown in the controller's instruction
manual and as seen in Figure 1.

Installation Instructions
1) Using the (4) provided 3/4" flat-head screws, install the two connected
keypads into a double-gang junction box or plaster ring.
2) Do not install the cover plate yet, as you will need access to the LRN
Keypad during programming.
3) Once all keypads are connected and installed, turn on the CA-Series
Multi-Zone Controller to power the keypads.
Programming Instructions
The command keys on the LRN Keypad are labeled for reference only. You
may program any IR command onto any command key.
1) Read the KP Keypad Control Features section of the CA-Series Multi-
Zone Controller manual.
2) Turn on the KP Keypad by turning the knob to the right.
3) Press the Program button on the left side of the LRN Keypad (button
locations are shown in Figure 3).
4) The Program indicator will light continuously (indicator light locations
are shown in Figure 3).
5) Select the desired layer by selecting the source input on the KP Keypad
(i.e. If you want to program CD player functions, select the CD source
on the KP Keypad.).
6) Press the command key that you wish to program into, on the LRN
front plate (i.e. If you wish to program the play function for your CD
player, press the PLAY button on the LRN.). The Program indicator will
now blink rapidly.
7) Hold your hand-held remote control so that the IR emitting end faces
the IR receiving diode located on the right side of the LRN Keypad (see
Figure 3 for IR receiving diode location). The hand-held remote should
be held 1-4 inches away from the IR receiving diode during command
transfer.
8) Press the command key on the hand-held remote that you wish to
program into the LRN Keypad's command key.
9) While the command is being transferred, the Program indicator will
light continuously.
1 0) After the command is successfully captured, the Stored indicator will
light momentarily, and the Program indicator will remain lit.
1 1) If you wish to continue programming command keys, repeat steps 5-
10.
1 2) If the Error indicator is illuminated, there was a problem processing the
last command. Repeat steps 5-10.
1 3) To exit the Program mode, press the Program button. All indicators will
no longer be illuminated, and the LRN Keypad will be ready for
operation (see Operation Instructions).
Clear Procedure Instructions
To Clear Individual Commands:
1) Press the clear button. The Program indicator will be illuminated. (Do

3) Press the command key to be cleared.
4) To continue to delete commands, repeat steps 2 and 3.
5) To exit the Clear mode, press the Clear button twice, or wait 5 seconds
