channel pattern. Labels cannot contain spaces, and they do not persist through a power cycle.
Channel labels can be up to 19 characters. Row and columns labels can be up to 8 characters. On
the crosspoint display, the first four characters of the label are displayed. On the bottom display, the
full label is displayed.
You can only set labels for slots and channels that are installed in the instrument.
