How do I switch SDI sources on the optional SDI interface board when I have an active signal connected?

• If you are connecting a single SDI cable, press the SDI button on the remote control to cycle through the SDI image sources (SDI-1, SDI-2, SDI-3, or SDI-4) to connect to the applicable SDI source signal . Each of the SDI ports on the SDI interface board is a separate image source when configured as a single link type.
