I have installed the drivers found on the website V3.0.0.2 but I can not change the usb traffic in ATP.
The toolbar in the setting window is missing.
I get it with my 120 but not with my 1600MM.
Do I have to change it somewhere else?

Thx

Hi,
Your camera is 1600mm Pro?
We think the usb traffic and the offset only useful when customer want to test the camera instead of doing some real imaging. So we removed it。
Is our decision a little too arbitrary?
Thanks

It is indeed the 1600MM Pro.
I will not miss it for deep sky.
It is more a matter with reducing the ROI when focusing.
But since I have the cam I could net do any test on the sky with the bad weather.

Hi,
Yeah, just try.
You know, in ASCOM, it is snapmode. In this mode, It will have a stop after one shooting. So this time is usually sufficient for USB transmission. Long exposure is more than enough. So tuning the USB bandwidth doesn't make much sense.
Thanks
chad

USB control is essential!!!

I use an ASI120MM for guiding and an ASI160MM-C for imaging with the 120 connected via the 1600's built in hub. All connected to a USB 2 port. Unless I reduce the USB traffic to 40% for both cameras the system becomes unstable, and either the imaging software or PHD2 stops get images.

Hi James,
Don't worry. This change is only for pro。So you still could control it for your 1600MM/C-Cool.
Thanks
