EVM WARNINGS AND RESTRICTIONS It is important to operate this EVM within the input voltage range of ±15 V and the output voltage range of ±15 V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 55°C. The EVM is designed to operate properly with certain components above 55°C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User’s Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.

1.5 Demonstration Software Control Software provided with the DEM-PCM/DSD1791 allows programming of the PCM/DSD1791 internal registers. The software operates on computers running Microsoft Windows 3.1, 95, 98 or 2000. The demonstration software requires connection of the PC printer port to CN003 of the demo board using a standard printer port cable. After installing and executing the demo software, the main window shows register bit codes and the sub-window shows register control function.

1.6 I2C Control The DSD1793 has an I2C control function. The I2C interface is provided on 5-pin connector RA001, shown in the following diagram. NC

1.7 Demonstration Software Demonstration software is provided to control the PCM1791/DSD1791’s internal register using a PC running Microsoft Windows. The software requires the use of a printer cable to connect between the PC and connector CN003 of the DEM-PCM/DSD1791. The demonstration software includes a total five files in the DEM1791; these files include the following: DEM1791.exe DEM1791.ini Vbrjp200.dll Ver.dll Inpout.dll Copy these files to a convenient directory (folder) such as C: DEM1791 Then change the printer-port address in DEM1791.ini to: &H378, &H278, or &H3BCO (Most PCs use &H378 as the default printer port address.)
