Connecting lap top to CAI 302

Borrowed the most recent Cambridge CD (V2.64 - not to be confused with
firmware v2.63 on the 302) that had the drivers for the USB
connection, instructions for deleting flight logs from the 302. Jeff
at R-Track Technologies tried to send them to me, but the firewalls
and anti-virus software didn't like the .exe files.

Happy to report that I can connect with the 302 using the USB, as well
as my own USB-RS232 adapter cable through the serial port, on at least
two different computers. Everything plays nicely (no crazy mouse
syndrome). I cleared off the flight logs (after grabbing files for
HyperTerminal - not included in Windows 7), and up loaded turn points
for Moriarty.

Now its time to start marking up the maps!

Two comments;

1) The serial/usb switch position is only applicable to later model
302's (after Dec 2008). My older model doesn't have this feature. I
am mentioning this so that when troubleshooting you ask which vintage
of 302 they have (can't tell from the front?). Do the new models all
have black cases while the old models have silver? Does an older 302
converted to USB ($175 with calibration) get a new black case?

2) The 302 memory issue - It seems to have several flavors. In my
case I got a "could not get fat" error. In other cases there are
security errors. My fix, and others, was to wipe the memory. I
brought together all of the information I could find (from RAS, etc)
into a single document available at; http://aviation.derosaweb.net/#cambridge302.

Good Luck, John DeRosa
