Video (Option)
Using appropriately terminated RG6 coaxial cable, connect the Video Out from an A/V source or video
distribution amp to the appropriate input on a zone TV or video display.
EXPANDED SYSTEMS
Two C-4.4 Controllers can be linked together to expand a C-4.4 system to up to eight zones. The
fundamental installation and connections are similar to those on a single controller system with a few
minor changes.
RS-232 Communication Link
This connection allows communication between the Master and Slave Controllers for zone/system status
and system/source power management from the keypads or remotes used in the zones connected to the
Slave Controller.
1.
Using a properly terminated 3-circuit (stereo) 3.5mm mini plug cable, (see section:
Wiring/RS-232
)
connect the RS-232 jack on the Master Controller to the RS-232 jack on the Slave Controller.
Source Audio
Source audio must be distributed to both the Master and Slave Controller Source Inputs to have source
audio signals available to all zones.
1.
Use either ‘Y’ adapters or an audio distribution amp to split the line level audio signal from the source
outputs to the source audio inputs on both controllers as shown in
Figure 14
.
NOTE:
If using an A/V Source an audio/video distribution amp is recommended to split the audio
signals to the C-4.4 Controllers and provide multiple video outs that can be distributed to the zone
video displays and maintain proper signal level.
IR Emitters
The IR Emitter Outs on the Master and Slave Controllers are independent in that they only output IR
commands from button presses from their respective connected keypads or IR commands sent from
remote controls via the IR receivers in those same connected keypads. (Button presses or remote
commands from Zones 1-4 only output from the Master IR Outs. Button presses or remote commands
from Zones 5-8 only output from the Slave IR Outs.)
NOTE:
Each Controller must be programmed individually for all source IR commands.
The IR Outs from the Master and Slave Controllers can be connected in parallel to a single emitter for
source control from any zone, as shown in
Figure 11
. When connecting emitters in parallel, be sure to
connect the matching source IR Outs from the Master and Slave, (i.e.: Master Source 1, Slave Source 1,
etc) or the press of a keypad button could wind up controlling the wrong source. To connect the Source
IR Outs in parallel:
1.
Using a 2-male to 1-female 3.5mm mono mini plug Y adapter, plug the two male ends into the
appropriate Source IR Outs on the C-4.4 Master and Slave Controllers.
2.
Plug an IR emitter into the female end of the Y adapter and attach the emitter to the device being
controlled over the IR eye. If the eye is not obvious, refer to the owner’s manual for that product or
shine a small flashlight into the front panel to locate the eye.
3.
Repeat for all sources to be controlled by both controllers.
