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
<Return>.
• 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 <Return> or BRIGHTNESS,-10 <Return>.
• You can also send a string of multiple commands on a single line, separated by commas.
For example, COMPOSITE,BRIGHTNESS
100,ANAMORPHIC <Return> 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 (- >).
