Configuring the Source Hub
In a cascaded Hub installation, the first UDM-0808-SIG Hub in the chain must be configured as the "Source"
Hub. Subsequent downstream Hubs must in turn be configured as "Target" hubs, and should follow a top
(Source) to bottom (Target #1, Target #2, Target #3) configuration.
"MMON" Send Command
Use the "’MMON’" Send Command to configure a Hub as the Source Hub in a Cascaded system:
Syntax:
SEND_COMMAND <DEV>,"'MMON'"
Example:
SEND_COMMAND dvUDM,"'MMON'"
Sets this Hub to Source Hub mode.

Analog audio is converted to digital audio before being sent to the UDM-RX02N
receivers. The required digital audio clock data is retrieved from the Cascade out
ports.
