Note:A total of 255 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/8 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/8=512, SW1/7=256, SW1/6=128, SW1/5=64, SW1/4=32, SW1/3=16, SW1/2=8, SW1/1=4. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=0, On=1)

MISCELLANEOUS TECHNICAL NOTE

Note: The PCD650M works in conjunction with the PICD650M & PXCD650M CD-ROM drives.
