Hi, I've just bought a Powercab Plus and connected it to my Helix LT using the L6 link cable. I've been able to program the PC+ speaker selection via the Helix (output setting) and I can see the colour change on the PC+ but the PC+ display doesn't change. I appreciate this is fairly minor but I wanted to check that is correct. Is there a change I can make that enables the display to change as well as the colour? Many thanks for any advice
