UDM-0808-SIG, UDM-RX02N and UDM-ABB-8-SIG Operation /Reference Guide
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. 65 illustrates the difference between the INPUT and PORT selectors:

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.

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.
