RS-232 Connection and 
Port Configuration
To interface the Vision 90t/100t 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 3-10. 
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 90t/100t RS-232 
port. 
6.2 
Serial Command Syntax
Serial commands to the Vision 90t/100t 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 90t/100t 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 
90t/100t ignores it and returns a minus sign (- >).

Serial Communications
Avoid combining the 
ON
 or 
POWER 1
 commands with other commands on a 
single line. After sending 
ON
 or 
POWER 1, 
allow at least 15 seconds for the 
projector to power up. Once it does, it will accept and properly execute 
multiple serial commands.
