I found a new Rotax Service Center near me and took my 912iS in for a 100 hour (500 hr total) inspection on Monday. This was the first time a dongle has been hooked up to my engine. After 30 minutes with no results, we gave up. How long should the download take? Granted there are 2 years & 500 hours of flight data to download, but what should the expected download time be?

I never had any Lane issues so we decided to abort the download and try again next time...

it usually takes about 10 minutes to download the fault and data logs from both Lanes.
Do you have the new version of BUDS? 3.0.1

There may be an issue here. I couldn't download my last plane. I have heard of others having the same problems. Even the service centers.

Rob,
This may be something to push up the chain of command.

Need details so it can be analyzed.
-Aircraft?
-BUDS version?
-One or two maintenance ports?
-Windows version?
-Did the BUDS program connect to the ECU (two green lights?)
-Did the download start?
-Any other details you noticed.
I noticed during the last class I was not able to connect with my old faithful laptop that has worked for years. Under the stress of a whole class watching I grabbed my new windows-10 tablet and it worked. Same Windows version, I cannot explain it.

Should this come from me (the aircraft owner) or my A & P?

It can be from either - whomever has the most complete information of the incident and the aircraft's condition handy...

Flocker: for an experiment can you (or a avionics tech) rewire your ports?
This is the way they should be wired:
- 2 DB9 serial port (less data conflict)
- 120 ohm resistor between the CAN Hi and CAN low wires. (At the DB9 end or the wire)
- 20AWG Twisted pair is the best choice for wire. Use the shield for CAN ground.

10-29-2018 444.6 hrs. TTSN Eng. serial # 4417104 Flight Design CTLSi Aircraft serial # F-12-03-10
It connected, showed both lanes green and the program tried to extract files, but could not. It just sat there and spun the wheel so to speak.I know CPS has had issues to.

Computer with Windows 7 has always worked until I used the new BUDS version. Tried at least 6 times and left it sit for more than 1 hour. I have another FD CTLSi to check next week that has always worked on this computer and with the old older BUDS so I'll see if it's the new BUDS version.
