Hi Sam,
will be hard with teamviewer as my Internet Connection is not the best one for such things.
Yesterday I could try SharpCap and Maxim DL.
Sharpcap: no Problem with the readout
Maxim DL: same effect again
I will uninstall ASCOM and install it again - maybe that helps.
SharpCap is OK but I am used to Maxim DL
Cheers Chris
