6. Universal SDK Demo App
The Universal SDK comes with a rich, fully featured demo app that allows users to run the VP3350 in
USB mode. Visit the VP3350 product page to download the Universal SDK Demo app as a standalone
executable, separate from the SDK; the full SDK is not required to use the demo. Be sure to check
out the Universal Demo QuickStart Guide for more detailed instructions about using the Universal
SDK Demo app.
6.1. Using the Demo Application
Follow the steps below to run the Universal SDK Demo app on Windows:
1. Plug the VP3350 into the host device with a USB-to-micro-USB cable (not included).
2. Double-click the UniversalSDKDemo.exe file and allow a few seconds for the main window
to appear (see illustration below).
The Universal SDK Demo app displays VP3350's available commands in a command tree, as shown
above. Single-click on a command to populate the center panel of the window with optional settings
relevant to the command (for example, "Amount" and "Start EMV Additional Tags" above). In some
cases, text fields appear, allowing users to enter custom values.
To execute a command, double-click it in the command tree (or use the Execute Command button at
the bottom of the window). The command executes in real time and a data trace appears
automatically in the center and/or right-hand panels. Use the Clear Logs button to clear both panels.
