2.
Connect the other end of the Cascade Cable to the appropriate AUDIO IN port on the ABB (1-4 or 5-8):


Audio clock data is taken from the AUDIO IN 1-4 port, hence a valid connection must
be made to this input for the ABB to work properly. The AUDIO IN 5-8 port is only
used if you intend to cascade audio from more than four outputs on the UDM Hub.
3.
Connect a UDM Cascade cable to the remaining Cascade Out port on the UDM-0808-SIG (CASCADE
1-4 or CASCADE 5-8), and connect the other end of the UDM Cascade cable to the appropriate AUDIO
IN port on the UDM-ABB-8-SIG.

Connecting Audio Outputs

The UDM-ABB-8-SIG provides 8 sets of audio output ports (RCA and SPDIF).

Use standard audio cables to connect the ABB to up to eight audio playback devices.

UDM-ABB-8-SIG Configuration

There is no direct configuration of the ABB. Rather, audio cascade options are configured on the source Hub
itself (via the "SFI" Send Command described below).
Refer to the UDM-0808-SIG NetLinx Programming section on page 13 for a listing of
all Send Commands supported by the UDM-0808-SIG.

"SFI" Send Command

Use the "SFI" Send Command (on the source UDM-0808-SIG Hub) to specify whether the cascaded audio
output on the source Hub will follow either:


For example, the cascade output for Input A on the source Hub can either be the signal from input A, or it
can be whatever signal is switched through to port 1 from the source Hub.

Use the AUDIO IN port labeled 1-4 to connect to the CASCADE 1-4 (OUT) port on the UDM
Hub.
Use the AUDIO IN port labeled 5-8 to connect to the CASCADE 5-8 (OUT) port on the UDM
Hub.
