Vidikron Vision Model 90 Owner’s Operating Manual 6-1
6.1
RS-232 Connection and
Port Configuration To interface the Vision 90 with a home theater automation/control system or a PC running
terminal emulation software, connect it to your control system or PC as shown in Figure 3-11.
Configure the RS-232 controller or PC serial port as follows: no parity, 8 data bits, 1 stop bit
and no flow control. Set the baud rate to 19200, to match that of the Vision 90 RS-232 port.
6.2
Serial Command Syntax Serial commands to the Vision 90 take the following form:
• Commands are not case-sensitive.
• For a single command that takes no parameters, type the command followed by a
carriage return; for example, to set the aspect ratio to Letterbox, type
LETTERBOX .
• For a single command that takes a parameter, type the command, a space or a comma
and the desired value followed by a carriage return; for example, to set the brightness to
-10, type
BRIGHTNESS -10 or BRIGHTNESS,-10 .
• You can also send a string of multiple commands on a single line, separated by commas.
For example, COMPOSITE,BRIGHTNESS 100,ANAMORPHIC switches to
the Composite video input, sets the brightness to 100 and sets the aspect ratio to
Anamorphic. Command strings can be up to 255 characters long.
Table 6-1 lists the RS-232 command set. The “Parameter (min/max)” column shows the valid
parameter ranges, or “NA” for commands that take no parameters.
When you enter a valid command, the Vision 90 executes it and acknowledges it with a plus
sign on the command line (+ >). When you enter an invalid command -- one that is
misspelled or followed by values outside the valid range for that command -- the Vision 90
ignores it and returns a minus sign (- >).
