1.9Demonstration Software

Demonstration software is provided to control the PCM1796/DSD1796 internal register using a PC that is running the Microsoft® Windows® operating system. This software uses a printer cable to connect the PC to the DEM-PCM/DSD1796 connector CN003.

The demonstration software includes a total of five files in the DEM1796 directory of the supplied CD. These files are:

∙DEM1796.exe

∙DEM1796.ini

∙Vbrjp200.dll

∙Ver.dll

∙Inpout.dll

To load the software, first copy these files to a convenient directory (folder), such as:

C:\DEM1796

Then, change the printer-port address in the DEM1796.ini initialization file to:

&H378, &H278, or &H3BCO

Most PCs use &H378 as the default printer-port address.
