* NOTE: You may see a popup indicating the publisher could not be verified, or Windows' User Account Control (UAC) may ask you if you want to allow this app from an unknown publisher to make changes. If you see either of these, or a notification similar to these, click allow or give permission to install.

Notes on PC interface cable: If you make sure your laptop is connected to the internet BEFORE you plug-in the PC interface cable, typically the driver software will load automatically. You can do this at your shop if you do not have internet access in the field. You should only have to do this one time for any given laptop. If this does not work, use the PC Interface Cable Driver software. Also, we recommend the latency time for the USB cable driver be checked every time the software is used. Here is a link to Service Bulletin 268 with details on latency timing adjustment. Westerbeke Service Bulletin 268.

How to use the software: After installation, when you open the program, at the top of the page click Help; and click Help again for instructions on how to use the software.
