3. Operation
3.1 Modes of Operation
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. (This is the default
mode).
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.
The third use of the front panel buttons is to reset the VS4-YCA to the factory default settings.
Press button 1 and 4 simultaneously for 3 seconds. This will turn off scan mode and set the
scanning interval to the default time of 5 seconds. This will also un-blank the outputs.
3.3 RS-232 control via Hyper Terminal

Baud rate: 4800
Data Bits: 8
Parity: None
