Note
Before using studio signalling on the CGP, the connected XCU must be configured to use
Ethernet based signalling (as opposed to using its own studio signalling GPIO inputs). To do
this, enter the menu in the XCU and go to the
INSTALL > SIGNALLING INPUT
submenu and
set the
ONAIR SOURCE
item to Ethernet.
