Hi

Several Line 6 devices use an ethernet cable to connect them together BUT it is NOT an ethernet connection or protocol that Line 6 uses.  Line 6 uses a proprietary communications protocol.  You cannot directly connect any Line 6 device to a computer using the connections that are made using RJ-45 sockets/ plugs and ethernet cables.  NEVER plug a Line 6 device into your computer's network ports.  You will almost certainly damage one or both devices
