Hi,

tnx for your answer!

I assume I'm using the original serial cable.
I bought my profilux plus 2 form someone who stopped his aquarium.
This cable was included in the package.

What's strange is that I am able to connect once in a while.
But most of the time it refuses.

You think it could be the cable?
Or else I maybe forced to buy a USB extension module :S

Grtz, Chris
