The Preh Touch Commander has been developed for the use with PC graphic adapters in 
SVGA-setting with 1024x768 pixels of resolution. As an operating system it is necessary to 
have either a DOS version 3.3 (or higher), Windows 3.1x, Windows 9x, Windows NT, 
Windows 2000 Windows XP or OS/2. 
For multimedia models a sound card with "Line Out" outputs for generating sounds is 
necessary in addition. 
 
 

 
The installation of the cables must be done

 

with the computer switched off. Set the 

correct screen resolution first. The optimum resolution is 1024x768 pixels and the refresh 
rate 60 Hz. 
To begin connect the VGA cable and the RS232 cable as well as the audio cable  (see 
pict. 3). Then plug in the AC power cable to the socket (see pict. 3). 
If you now switch on the computer, the LED lights up green after about 3 seconds and the 
corresponding picture appears on the screen. If the computer is in suspend or standby 
mode the LED is red. If the SVGA cable between Touch Commander and computer is 
disconnected, or that the computer power is switched off, the LED lights up red.
