ALLSCANNER runs it's own operating system which allows it to be used as a standalone tool without a PC attached during operation. Imagine writing your own C/C++ application to perform an on-road test, then use 802.11A/B/G WiFi to wirelessly download a vehicle's data as soon as it re-enters the repair facility. Your program could access GPS compact flash card to capture location information about the test-drive, or use a cellular modem and download telemetry from live tests! For standalone applications, this provides the features of a PC host and a PassThru device all in one package
