Important: Note that the DAC output connector (CN8) can also be used to
output selected servo information using a feature called DAC monitor.
This feature is controlled by Patch AMP. Refer to the 9/Series CNC 9/230,
9/260, and 9/290 AMP Reference Manual, publication 8520-6.4, for more
information.
CN9 Touch Probe Connector
The digital servo module receives touch probe feedback through connector
