OK, dank. Sehr schade, das wär für mich genau richtig gewesen. Habe auch das im Amiforum gefunden:
Do not use the CAT 5 cable on that into the Axe-fx. You have a good chance of frying both the Control2 and the Axe-fx's Expansion port.
The control2 is specifically for the gsp1101 (or other digitech product that specifically state they can use the control2).
As it states in the control2's owners manual:
"WARNING: Only connect the Control 2 Remote Foot Controller to
the GSP1101 or other DigiTech products which specify a connection to
the Control 2. Do not connect the Control 2 Remote Foot Controller
to Ethernet connections as damage will occur."
