The TP-100 can be considered for an ALLin1DC installation only if its contacts can reproduce the controller’s required input closures. The available evidence does not define the TP-100 contact arrangement or establish a separate MPU11 requirement, so compatibility remains conditional until continuity tests confirm the behavior below.
Required Probe and Detect Signals
The standard probe input is INP769. Trigger it by closing pin 8, the mechanical probe input, to either pin 2 or pin 3, both identified as 12 V return. A preferred installation adds a second circuit that closes INP771 through pin 9 to pin 2 or pin 3 whenever the probe is connected.
Probe triggered: pin 8 → closed to pin 2 or pin 3
Probe connected: pin 9 → closed to pin 2 or pin 3The detect circuit lets the CNC software inhibit a built-in probing cycle when no probe is connected. It also lets the PLC program prevent spindle starting while the probe is connected.
ALLin1DC Probe Connector Pinout
View the connector from the board side, or look into the back of the plug housing, with the locking ramp or clip upward. Count pins from right to left across the bottom row, then from right to left across the top row.
| Pin | Function |
|---|---|
| 1 | Chassis ground |
| 2 | 12 V return |
| 3 | 12 V return |
| 4 | +12 V |
| 5 | +12 V |
| 6 | Chassis ground |
| 7 | DSP probe input |
| 8 | Mechanical probe input |
| 9 | Probe detect input |
| 10 | Auxiliary probe input |
Compatibility and Verification Procedure
- With the TP-100 disconnected from the controller, use continuity testing to identify the contact pair that changes state when the stylus triggers.
- Confirm that this pair can provide an isolated closure between ALLin1DC pin 8 and pin 2 or pin 3. Do not assume compatibility from the probe model name alone.
- Determine whether the probe or its connector provides a separate presence contact. If available, wire it to close pin 9 to pin 2 or pin 3 whenever the probe is plugged in.
- Connect the probe and verify that a stylus event changes
INP769. Verify separately that connecting and disconnecting the probe changesINP771when the detect circuit is implemented. - Confirm that probing is inhibited with the probe disconnected and that the PLC blocks spindle starting while the probe is connected.
The evidence does not establish whether the TP-100 supports digitizing, center probing, edge probing, or Intercon workflows. Verify those application functions independently after proving the electrical interface. If the Ajax/Centroid probing-cycles software option is not installed, create the required CNC macros using M115/M116, M125/M126, and IF/THEN/GOTO; the cited source directs users to Chapters 13 and 11 of the Operator’s Manual.
Frequently Asked Questions
Will a TP-100 contact probe work with an ALLin1DC controller?
It can work only if its trigger contacts close ALLin1DC pin 8 to pin 2 or pin 3. Test the TP-100 contacts before wiring because its internal contact arrangement is not established by the available evidence.
Which ALLin1DC input indicates that the probe has triggered?
The standard mechanical probe input is INP769 on pin 8. Trigger it by closing pin 8 to the 12 V return on pin 2 or pin 3.
How does the ALLin1DC detect that a probe is connected?
Use a separate presence circuit to close INP771 on pin 9 to pin 2 or pin 3 whenever the probe is plugged in. This supports probing-cycle inhibition and a PLC spindle-start interlock.
