DEMO MANUAL DC1613A I2C/SMBUS/PMBUS Controller DESCRIPTION Demonstration circuit 1613A is a USB-based controller with generic Inter Integrated Circuit (I2C) 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 dc1613af 1 DEMO MANUAL DC1613A QUICK START PROCEDURE For proper equipment setup, follow the procedure below: SOFTWARE TOOLS 1. Do NOT plug in the DC1613A to the PC, before running the installation program. The LTpowerPlay demo software includes tools for automatic software updates and for quickly retrieving relevant documentation from the World Wide Web. 2. Download the LTpowerPlay installation program from http://www.linear.com/software/. NOTE: Adobe Acrobat Reader is required to view the documents and is available at http://www.adobe.com. 3. Run the LTpowerPlay installation program and follow the on-screen instructions. To use the tools: The LTpowerPlay demo software requires a PC that is running Windows XP (or later), and has an available USB port. • Quit the demonstration circuit software or disconnect the USB cable so that the main control panel appears: 4. Connect the demonstration circuit to be evaluated to the DC1613A using the supplied 12-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. 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. dc1613af 2 DEMO MANUAL DC1613A TROUBLESHOOTING GUIDE Problem: DC1613A is plugged in, but LTpowerPlay screen still says “USB Serial Controller Not Connected.” Problem: Demo board software loads properly, but will not run or gives “Device Not accessible” errors. Solution: The most likely cause is improper installation of the USB drivers, which causes Windows to recognize the DC1613A 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 DC1613A, reinstall the LTpowerPlay software and follow the on-screen instructions. Solution: Verify that the demo board is properly powered up. This Quick Start guide lists the basic power connections to DC1613A. 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 DC1613A with the supplied 12-pin ribbon cable, LTpowerPlay software still displays “Evaluation Board is not Connected.” Solution: Contact Linear Technology Applications Engineering. dc1613af 3 A B C D R63 OPT 0 R64 0 OPT R65 0 OPT R3 20k R66 OPT 1k 3 2 1 R67 0 OPT SET GND V+ 4 5 5 2.
