"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.
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 of the Hub.
Syntax:
SEND_COMMAND <DEV>, "'SFI<I#>F<F#>'"
Variables:
•I# = Input number (initial 'I' may be omitted):
1-8 = Inputs A-H (on the UDM Hub)
•F# = Output (on the UDM Hub) to follow selector:
"INPUT" = local input (default setting)
"PORT" = switched port input
Example 1:
SEND_COMMAND dvUDM,"'SFI2FINPUT'"
Sets expansion channel 2 to be whatever is connected to input B.
Example 2:
SEND_COMMAND dvUDM,"'SFI2FPORT'"
Sets expansion channel 2 to be whatever is connected to output port 2 (it
follows port 2 as it is switched from one input to another).
FIG. 4 illustrates the difference between the INPUT and PORT selectors:
"SAI" Send Command
Use the "SAI" Send Command to configure a specific audio input to accept
signals of a certain type, and set the source as either a local source (devices
connected directly to the inputs A-H on the UDM Hub to which the ABB is
connected) or cascaded from an upstream UDM-0808-SIG Hub.
Syntax:
SEND_COMMAND <DEV>, "'SAI<I#>T<T#>C<C#>'"
Variables:
•I# = input number - a value of zero indicates all inputs, initial 'I' may be
omitted.
1-8 = Inputs A-H
•T# = type of incoming audio:
"NONE"
"ANALOG"
"DIGITAL"
•C# = Cascade selector - if present assume CASCADE, if not assume
LOCAL.
"LOCAL"
"CASCADE"
Example 1:
SEND_COMMAND dvUDM,"'SAI2TANALOG'"
Sets input B to accept analog stereo signals from "local" devices (source
devices connected to the UDM input connectors).
Example 2:
SEND_COMMAND dvUDM,"'SA3TDIGITALC'"
Sets input C to accept digital audio from an upstream UDM Hub.
Example 3:
SEND_COMMAND dvUDM,'"SAI7DIGITALCLOCAL"'
Sets input G to accept digital audio from "local" devices.

SFI (selector = INPUT)
With the SFI command set to
INPUT, the UDM cascades the
audio from the source device
connected to an Input (A-H) on the
UDM.
In this example, Input A on the UDM
is cascaded to Output 1 on the ABB,
Input B on the UDM is cascaded to
Output 2 on the ABB, etc...
This is the default setting for the
inputs on the UDM hub.

ABB Output 2
ABB Output 3

Port 1 Port 2 Port 3 Port 4 SFI (selector = PORT)
With the SFI command set to PORT,
the UDM cascades the audio from a
UDM port rather than the physical
Input connectors.
In this example, Port 1 on the UDM
is cascaded to Output 1 on the ABB,
Port 2 on the UDM is cascaded to
Output 2 on the ABB, etc...
This option allows you to cascade
audio from source devices beyond
those that are physically connected
to the UDM Hub.
