Installing the CTA 150i card in your PC
Setting the address switch

shown in Figure 1. This setting indicates that the card operates at address
300H.
Figure 1 CTA 150i card address switch settings
You may need to reset the address switch so that it does not conflict with
other hardware address settings on your computer.
The I/O port address must be a hexadecimal number between 200 and 3F0.
It must also be a multiple of 10 hex. Table 1 shows the alternative settings.
Do not use a pencil to change the switch settings; graphite
deposits from the pencil lead are electrically conductive and can
cause a short circuit in the switch.
