Audio Switcher Bussing Kit:
CNX-ASBK
Description
Functional Description
The Audio Switcher Bussing Kit, CNX-ASBK, is used to daisy-chain CNX-PAD8s
to expand the number of room outputs. Each CNX-PAD8 controls up to eight audio
sources and distributes the audio to up to eight room amplifiers (not supplied). A
maximum of four CNX-PAD8s may be daisy-chained together to provide up to 32
room outputs. The CNX-ASBK provides for the additional outputs by bussing up to
eight inputs while preventing extreme impedance loading. One kit is needed for each
CNX-PAD8 that is to be daisy-chained.
Physical Description
Each CNX-ASBK consists of one Point Cross Loop Printed Circuit Board (PCB)
Assembly, eight 4-conductor Cross Point PCB to Processor PCB Cable Assemblies,
and four 12-conductor Bussing Cable Assemblies. Refer to the physical views shown
after this paragraph.

Identity Codes of the CNX-PAD8s
Every equipment and user interface within the network requires a unique identity
code (Net ID). These codes are recognized by a two-digit hexadecimal number from
03 to FE. The Net ID of the unit must match an ID code specified in the SIMPL
Windows program. The Net ID of CNX-PAD8s is factory set to 44. The Net IDs of
each of the daisy-chained CNX-PAD8s must be unique and changed from a PC via
VisionToolsTM Pro-e (VT Pro-e) or SIMPL Windows.
The method for changing the unit’s Net ID is identical regardless of the software
chosen. Verify that the control system software is running and complete the
following steps to change the Net ID:
(SIDE VIEW)
KEY
1. Disconnect all network devices from the control system.
2. Attach one of the CNX-PAD8s that needs to have its Net ID changed to
the control system.
3. Select Tools | Viewport to open “Crestron Viewport” dialog box.
4. Select Functions | Set Network ID. The software checks the baud rate
and then opens the “Set Network ID” dialog box.
5. The list of current network devices is normally shown in the dialog
box. Highlight the CNX-PAD8.
6. The Net ID of the CNX-PAD8 (default is 44) appears in the box below
the list. Use the scroll arrow to assign another Net ID.
7. When the newly assigned Net ID appears, select the Set ID button to
initiate the change.
8. The software responds with a successful message to confirm the new
Net ID.
9. To verify this procedure, select Diagnostics | Report Network
Devices. Confirm that the CNX-PAD8 has a new Net ID code.
10. Repeat steps 2 - 10 of this procedure for each CNX-PAD8 that needs its
Net ID changed.
11. Reconnect other network devices that were disconnected in step 1.
