Overview of this chapter
 
This chapter provides instructions and information for installing and 
configuring the Norstar Computer Telephony Adapter 150i. The instructions 
in this chapter are designed for experienced PC users who are familiar with 
card installation.
 
Installing the CTA 150i card in your PC
 
Setting the address switch
 
The CTA 150i card comes with the I/O port address switches preset as 
shown in Figure 1. This setting indicates that the card operates at address 
300H.

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.
