4.1 DASCCT_AIC23 Installation

Before running the DASCCT_AIC23 software, the parallel port must be configured for enhanced parallel port (EPP). The parallel port configuration can be changed in the system setup during system boot up. Some computers have a bidirectional mode, which also works. (Some have PS2, which may also work.) The connection diagram for the equipment is Figure 4–1.

1)Insert the software CD labeled DASCCT_AIC23 1.0 into the CD-ROM drive of the PC.

2)Open the Start menu and then click Run.

3)Type D:\SETUP and press <ENTER>. If the CD-ROM drive is not D:, substitute the appropriate drive letter. Follow the instructions presented by the setup wizard.

4)Connect the analog input from a CD, DVD player, or any alternative analog source to the TLV320AIC23/DAC23 EVM2.

5)Connect the TLV320AIC23/DAC23 EVM2 to the speakers or headphones that will be used for listening.

6)Connect the parallel port interface card to the parallel port connector of the PC.

7)Connect the cable provided in the kit between I2C connector J5 on the TLV320AIC23/DAC23 EVM2 and connector J2 on the parallel port interface card.
