NAME

set60, set30, setntsc − set video output type

SYNOPSIS

/usr/people/mexdemos/bin/set60
/usr/people/mexdemos/bin/set30
/usr/people/mexdemos/bin/setntsc

DESCRIPTION

These programs set the video output of the IRIS to one of the three possible modes.  set60 sets the output to 60 Hz non-interlaced, set30 sets it to 30 Hz interlaced, and setntsc sets it to RS-170 NTSC video. 

NOTE

The IRIS can be set up to display only two out of the three types of output (unless the user swaps boards).  The users can pick which two display modes they want when they order their system.  This means that only two of these three commands are going to affect the display.  Typing a command that causes a mode that is not installed on the system will have no effect. 

WARNING

When one of these commands are executed, the video output is set to that type.  If the display device is not of that type, the screen will display garbage.  The keyboard will still accept input.  Enter the command to set the video to the correct mode.  This will restore the image on the screen.
