Chapter 14: Exporting using ASCII Link
ASCII Link is a utility program that lets you download data from the Welch Allyn OAE Hearing
Screener unit's memory to a PC and convert it to an ASCII file. This tool lets you save Welch Allyn
OAE Hearing Screener data in your own spreadsheet where you can use it for research. To use
the ASCII Link program:
1. Install the ASCII Link program from the Welch Allyn OAE Inservice Guide CD.
2. Attach the Welch Allyn OAE Hearing Screener unit to the computer using the USB cable
provided with the system.
3. Launch the ASCII Link program.
(Be aware that this application will automatically delete all tests from the Welch
Allyn OAE Hearing Screener memory after the conversion to ASCII format has been
performed.)
This application automatically transfers the data from the Welch Allyn OAE Hearing
Screener to the computer and converts it to an ASCII file.
4. The ASCII file “transfer.axo” can be found in one of the following folders depending on the
operating system in use as follows:
• In Windows 7, the ASCII file “transfer.axo” is found in the folder
C:\ProgramData\Welch Allyn\ASCII Link.
• In Windows XP the ASCII file “transfer.axo” is found in the folder C:\Documents
and Settings\All Users\Welch Allyn\ASCII Link.
