PrecisionHD Camera 1080p12x.
Video mode selection
The DIP switch selection has priority over the selection made
by the CAM_Video_Format command. If the DIP switch is set
to auto, the CAM_Video_Format setting is used. If both are set
to auto, resolution is controlled automatically by EDID.
DIP Switch settings
The switches are numbered 1 to 5. The VISCA column shows
the value that must be used when using the CAM_Video_
Format command.
NOTE: The DIP switches are only read by the software at
startup/boot. Therefore if the DIP switches are changed the
camera must be rebooted.
If an undefined mode is selected, the output defaults to auto.
