Didn't realize the difficulty that many were having locating cables that work with INPA and NCS Expert. Seems like either the failure rate is alarmingly high or some vendors are marketing cables as compatible when they are not. Cerenkov was kind enough to bring this to my attention in a thread I started about logging software here.

The same company discussed there also sells K+DCAN cables that have been pre-tested and are guaranteed to work.
