PC*MILER Rail-Connect includes a tester that runs many of the more commonly-used APIs. To access the Connect or Mapping tester, go to the Windows Start menu > All Programs (or the equivalent on your system) > PCMILER Rail xx > Connect Tester.

The Connect tester runs automatically when it is opened and outputs two files into the App folder of the PC*MILER Rail installation (usually C:\ALK Technologies\PCRWINXX\App):  pcrstest.log logs the progress of the tester program.
