Programming path functions
You can program path functions conveniently by using the gray path
function keys. In further dialogs, you are prompted by the TNC to
make the required entries.
If you enter DIN/ISO functions via a connected USB
keyboard, make sure that capitalization is active.
At the start of the block the control automatically
writes in capitals.
