1.2 Software Installation
The software is provided on the TI Web site. Run the setup.exe program to install the GUI. For more
details, see
Section 1.5 , Basic Graphical User Interface Controls.
1.3 Connections
The connections are for an analog signal for the input, speaker loads, power, and I
2
C. The audio inputs
are made through the four RCA connectors. The power connectors and speaker connectors are made
using the 10-pin connector.
The I
2
C connections are made through a 6-pin DIN connector. The provided adapter PCB and cable
connect the EVM to the PC. The adapter PCB is an I
2
C-to-USB converter, which is a human-interface
device (HID) and is automatically recognized by the PC when connected. Therefore, no drivers are
needed.
The basic connections are: PVDD or power is connected to the EVM through the supplied 10-pin
connector with the twisted red and black wires. The speakers or loads are also connected through the
same 10-pin connector with the twisted red and white wires. The 6-pin DIN is connected to the I
2
C-to-USB
adapter board. See Figure 2 for EVM input details.
