DEMO MANUAL DCA I C/SMBUS/PMBUS Controller DESCRIPTION Demonstration circuit A is a USBbased controller with generic Inter Integrated Circuit (I C) ports as well as SMBUS/PMBUS capabilities. It is designed to mate with Linear Technology s family of LTpowerPlay demonstration boards. The demo board is fully isolated from the host PC s ground. The evaluation software automatically detects which demo board is connected and loads the appropriate control screen. The LTpowerPlay system provides a quick and easy way to evaluate the performance of a wide variety of Linear Technology s products L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and LTpowerPlay is a trademark of Linear Technology Corporation. All other trademarks are the property of their respective owners. DEMONSTRATION CIRCUIT TO SMBUS TO USB dcaf
DEMO MANUAL DCA QUICK START PROCEDURE For proper equipment setup, follow the procedure below:. Do NOT plug in the DCA to the PC, before running the installation program.. Download the LTpowerPlay installation program from http://www.linear.com/software/.. Run the LTpowerPlay installation program and follow the onscreen instructions. The LTpowerPlay demo software requires a PC that is running Windows XP (or later), and has an available USB port.. Connect the demonstration circuit to be evaluated to the DCA using the supplied conductor ribbon cable. The demo software detects the circuit and starts the appropriate control screen. Each demonstration board also comes with a Quick Start guide similar to this one. For usage details relevant to a particular circuit refer to its Quick Start guide. SOFTWARE TOOLS The LTpowerPlay demo software includes tools for automatic software updates and for quickly retrieving relevant documentation from the World Wide Web. NOTE: Adobe Acrobat Reader is required to view the documents and is available at http://www.adobe.com. To use the tools: Quit the demonstration circuit software or disconnect the USB cable so that the main control panel appears: To update the software (requires internet connection): Choose Update from the Tools menu. This automatically updates the main program and drivers for individual demo circuits. dcaf
DEMO MANUAL DCA TROUBLESHOOTING GUIDE Problem: DCA is plugged in, but LTpowerPlay screen still says USB Serial Controller Not Connected. Solution: The most likely cause is improper installation of the USB drivers, which causes Windows to recognize the DCA as an Unknown Device. Open the Windows Control Panel, open System and click the Device manager tab. Open the Other Devices item and look for USB SERIAL CONTROLLER. Select this item and click the remove button. Unplug the DCA, reinstall the LTpowerPlay software and follow the onscreen instructions. Problem: Demo board software loads properly, but will not run or gives Device Not accessible errors. Solution: Verify that the demo board is properly powered up. This Quick Start guide lists the basic power connections to DCA. Some demo boards may have additional requirements; refer to the demo board s Quick Start guide for details. Problem: After connecting the demo board to DCA with the supplied pin ribbon cable, LTpowerPlay software still displays Evaluation Board is not Connected. Solution: Contact Linear Technology Applications Engineering. dcaf
