RS-232 control via Hyper Terminal
To use the RS-232 control interface, start Hyper Terminal with the
following settings:
Baud rate: 4800
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
This is what the menu will look like in Hyper Terminal.
Ver 1.x a = Auto Mode
MENU s = Scan Mode
-------------- b = Blank
1 = #1 Input u = Un-Blank
2 = #2 Input p = Priorities
3 = #3 Input r = Reset
4 = #4 Input l = Lock/Unlock
The version number displayed will be similar in the format shown.
By pressing the number keys, “1”, “2”, “3”, “4”, the VS-4 will switch
to that VGA input. This will also put the VS-4 into Normal Mode.
Pressing “a” will put the VS-4 into Auto Mode.
Pressing “s” will put the VS-4 into Scan Mode. Before the VS-4 enters
Scan Mode, you will be asked 2 questions. The first question will be
“Seconds between switching? (1-60)”. To this question, you must input
a number between 1 and 60 then press enter. Any other input will cause
this question to be repeated. The second question will be, “Scan non-
active? (y/n)”. You must answer this question with a “y” or an “n”.
Any other input will result in this question being repeated.
Pressing “b” will blank all output from the VS-4 until the un-blank
command is received.
Pressing “u” will un-blank the output from the VS-4 if it was
previously blanked.
