I noticed some people having issues with USB to Serial drivers when trying to communicate with some jiggers, the work around i found was using PL2303_Prolific_DriverInstaller_v1.7.0 and installing it as XP mode.
Not sure if im aloud to post URL's but its here.

This has worked for all Top-Con equipment so far. I tried ever version from 1.1 to 1.10 and none work on CF-18's-19's and CF-U1's. Only the 1.7 worked when installing as XP mode, if you run as default installation it will not work.

That's the drivers I used and I've had no problems either.
This is great. Thanks alot.
This driver works for my FC-100.
