Scan Mode -
Will cycle through and select each S-Video/Audio signal for a
programmed number of seconds (1 to 60), and then switch to the next S-
Video/Audio input.
Normal Mode -
S-VIDEO/AUDIO inputs are selected based on user input.
(default)
The VS4-YCA can only be in one of these modes at a time.
3.2 Front-Panel Switches
The first function of the front panel buttons is to switch from one S-Video/Audio
signal to another. Just press the button and the S-Video/Audio signal you
selected will be routed to the output. If there is no S-Video/Audio signal to be
displayed then you will see a black screen. The VS4-YCA will enter Normal
Mode any time a single front panel button is pressed.
The second use of the front panel buttons is to put the VS4-YCA into Scan
Mode. Press buttons 3 and 4 simultaneously and the VS4-YCA will enter Scan
Mode. The time interval between switching will be the time interval last
specified via Hyper Terminal. If no interval has been specified then the default is
5 seconds.
