1 The True level (voltage transition the probe fires) is either “HIGH”or “LOW”as defined
by the AMP parameter PROBE TRANSITION. Refer to the 9/Series CNC 9/230,
9/260, and 9/290 AMP Reference Manual, publication 8520-6.4, for more
information.
Important: The touch probe connector supports only +5V probing device
applications.
The 9/230 can have two LEDs (DS4 is present only if you have purchased
the 9/230 remote I/O option). Figure 3A.1 shows the location of these
LEDs on the main board. Use them to determine the following:
