Mac Computrainer not working


(stefan raab) #1

I am able to see it in the setup, but as soon as I start to ride the computrainer display goes back to calibration and then I am never able to ride.

It seems to work fine with my powertap.

Also, do I have to login and setup every time I start the app? Seems like it isn’t saving settings.

Also onetime it started working with my CT in the background behind the login screen.

I have the same issue and would really like to know if someone has figured out the issue.

I was having the same problem and a friend told to hit the A key while in zwift to see if the Computrainer was still the power source. It wasn’t so I repaired and it seems to work now.

Thanks! Hitting the “A” key worked!

I confirm the same issue. Haven’t had a chance to hit “a” to fix, but I’ll try it soon. Glad someone noticed this.

I am kevins friend who figured this out. You all owe me a lead out for the green jersey if you are online at the same time as me, FYI…

What kind of serial adaptor are you using to connect the Mac? My Mac will see the computrainer, but does nothing once I start pedaling. Do you have to do anything to the computrainer controller to start? Please let me know and thanks.

I use the USB to Stereo Adapter bought off the Racermate website.

I’m using the FTDI USB to serial adapter that came with my 10 year old CT. It has been very flaky with Zwift. Sometimes I have to select it 5 or 6 times before it actually takes it. You’ll know it’s working when you see power on the selection screen.

Same or similar problem. Zwift see’s the computrainer in pair mode, takes a few seconds and finally shows watts and then when you join the ride it drops the resistance/power immediately. Are you hitting “a” after you join the island?

Thanks,
Don

BTW, I’m mac mavericks with the ftdi adaptor.

yes, after you join the island and it shows your avatar sitting on the side of the road waiting, hit the A key to enter the screen where you can select your devices and re-select your computrainer as the power device.

Thanks Josh, much appreciated
