Designing an Interface Between a P6434 Probe and a Target System
P6434 Probe Instructions
21
AMP Probe Channel Assignments (Preferred)
The 17 channels to which the module end connects on the logic analyzer cannot
be changed. When mapping signals from your target system to channels on the
logic analyzer, you must keep the probe section, clock, and/or qualifier channels
together as shown in Tables 1 or 2 on page 3.
Each probe connector has 43 pins; pins 39 through 43 are the five ground pins.
Pins 1, 2, 3, and 4 are unused, and it is recommended that they be connected to
ground.
The preferred pin assignment is the AMP pin assignment (see Table 4), because
other commercial CAD packages use the AMP numbering scheme as the
industry standard. Table 4 shows the pin assignments for the surface-mounted
connector. Pin assignments are the same for the straddle-mounted connector.
AMP uses an odd-side even-side pin assignment. Pin 1 is located at the top left,
and pin 3 is located directly below it. Pin 2 is located on the top right, and pin 4
is located directly below it. Refer to Table 5 on page 22 for the pin assignments.
NOTE
. When designing Mictor connectors into your target system, always verify
which pin-numbering sequence your CAD system uses.
