In my case, my pendant is all plug and play and "connectorized", so that would have involved disassembling a DB25 (I think) or the pendant itself, unsoldering pins etc.
That would work, but too much work in my particular setup. I am glad they give a swap option or I would have been stuck doing that.
I am finding that I think I like my control panel jog buttons and twist knobbing to the speed I want better than spinning the wheel on the pendant though. It is nice though if you want to get a closer look and not be reaching up to the panel.
