Wiring a Probe for Falling Edge Configuration
Figure 4B.41 shows a typical wiring diagram compatible with most probe
designs configured to trigger on the falling edge of the probe signal.

Wiring a Probe to Multiple Servo Cards
Systems with more than one servo module should have their touch probe
connections tied together in parallel. This allows the position to be latched
on all servo modules at the same time with the same input. Only one
power connection needs to be made (with pull up or down resistor). The
other probe connections should be made in parallel on all servo cards.
