D-sub 25-pin plug control element
This cable allows the control elements (buttons and switches) on the front
cover of the CNC control panel to be connected to the corresponding
safety circuit modules in the switching cabinet.
Power (+24V DC) to the USB hub on the control panel is provided by
this cable.
Make sure that the keyboard, touch screen and USB interfaces only
function when connected to the safety circuit modules.
