2.
Connect the other end of the Cascade Cable to the appropriate AUDIO IN port on the ABB (1-4 or 5-8):
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.
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).
"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:
the local input (a source device connected directly to the Hub)
- or -
the input that has been programmatically switched to the associated output port (see the
SEND_COMMANDs section on page 15).
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.
Syntax:
SEND_COMMAND <DEV>, "'SFI<I#>F<F#>'"
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.
