CRESNET
The 4-pin network connector is used to connect the CNX-PAD8 to the Cresnet
system. When the unit is connected to the system, power can be provided via the
connection and the external power pack is not required. Review the Network
Interconnection Diagram (latest revision of Doc. 5411).
The two 6-position RJ11 modular jacks are pass-through connectors that are also
used to connect the unit to either the SmarTouch STS (ST-CP) or Cresnet system.
The two modular jacks are available so that network units can be daisy-chained
together. Review Network Modular Cable Requirements (latest revision of Doc.
5682).
NOTE:
Most 4-conductor phone cables are wired in a crisscross fashion and are not
compatible with Crestron equipment.
If an external power pack is attached when the CNX-PAD8 is part of the Cresnet
system, power is drawn from the power pack. The unit does not load the network
power, but the network power remains chained for additional network devices that
are connected.
G (Chassis Ground)
Use this chassis screw to connect the audio source(s) common ground(s) to the
CNX-PAD8.
SOURCE 1 - 8
Each of the eight sets of four RCA connectors is used to connect the independent
audio sources to the CNX-PAD8. Of each set, two of the connectors are used for the
left and right audio channels and the remaining two connectors are parallel stereo
loop-throughs.
The eight rectangular blanks (labeled 1-2, 3-4, 5-6, and 7-8) are used with the
optional Audio Switcher Bussing Kit. The kit contains a printed circuit board with
eight connectors that when installed, is used to daisy-chain three additional
CNX-PAD8s to provide up to a total of 32 room outputs. Refer to the latest revision
of the CNX-ASBK Operations & Installation Guide (Doc. 8143) for further
information.
ROOMS 1 – 8
These eight pair of RCA jacks output the pre-amplified audio to the corresponding
room(s) amplifier(s). Each room output contains left and right audio channels.
