Designing an Interface Between a P6434 Probe and a Target System
P6434 Probe Instructions

Mechanical Layout and Pin Numbering Sequence
of Compatible Mictor Connectors
Each compatible Mictor connector has 43 pins; pins 39 through 43 are grounded.
Pins 1, 2, 37, and 38 are open. Figure 17 shows the positions and spacing between
the pins, the keyhole, and the latch housing mounting holes of a surface-mounted
connector. Table 4 on page 21 shows the recommended pin assignments.
Pin 1 Indicator
If you include the latch housing in your design, be sure to place a pin 1 indicator
on your circuit board during design because the latch housing obscures the pin 1
indicator on the Mictor connector. Even though the Mictor connector is keyed,
you still need to know the location of pin 1 when connecting the P6434 probe.
