Basic Operating Set-Up

3.1Basic Operating Set-Up

Follow these steps to set up the DEM-DAI3793A/3794A EVM for operation.

Step 1. When using the kit for the first time, install the TUSB3410 VCP (Virtual COM Port) driver to the host PC. To install the driver, refer to the Virtual COM Port Driver Installation Instructions.pdf located in the DEM-DAI3793 folder of the software CD or available through the TI web site.

Step 2. Connect the audio signal sources and/or receiver, using one of these connections:

S/PDIF cable (optical or coaxial)

Analog input/output (RCA)

Step 3. Connect microphone, speakers, headphone, an audio amplifier, or measurement equipment, if necessary.

Step 4. Confirm that jumpers CN103–CN107 are shorted.

Step 5. Connect the USB cable between the host PC and the motherboard (CN201). Step 6. Apply +6V to +10V to the motherboard (CN101, CN102 for power supply). Step 7. Execute EVM3793A.exe.

When the installation is complete, the EVM software is ready to use.
