Reseat the cable on both ends and then, in the PathPilot interface, check to see if the ATC tab does not disappear after 30 seconds. If the ATC tab does disappear, try replacing this cable and and rechecking PathPilot for the ATC tab.

440 ATC
Reason: ATC board may not be getting voltage causing check fuses and cabling error.
Inspect your ATC board for LED lights that are illuminated. If you have no lights at all, move to the step.
If you have lights on your board but still no communication, ensure all wires are properly seated and secured in the terminals on the ATC board itself and try and reseat the connector
Check for 48 Vdc across wires 204 200 and 205 201 at the ATC control board.

If you have voltage at the board but no lights, estop the machine, then remove components from the board one at a time. (excluding the incoming power) Then power back up, to vet if a component is shorting the board.
If you do not have +48 Vdc across wires 204 200 and 205201, move to the 48V Power Supply in the machine column. Measure for 48V DC on the power supply from the V+ and V- wires from the ATC.

Your ATC board should show the following LEDs lit if it has +48 Vdc at wires 503 204 and 504 205 at the ATC control board and is successfully talking to PathPilot.

If you have +48 Vdc at wires 503 204 and 504 205 at the ATC control board but no lights on the board, contact Tormach Tech Support, estop the machine, then remove components from the board one at a time. (excluding the incoming power) Then power back up, to vet if a component is shorting the board.
If you do not have +48 Vdc across wires 503 204 and 504205, move to the 48V Power Supply in the machine column. Measure for 48V DC on the power supply from the V+ and V- wires from the ATC. If the ATC won’t communicate and the ATC tab goes away, but the power drawbar opens/closes and the Status tab shows when the USB is removed and replaced, then inspect the RJ11 (DB3) cable for damage. Reseating and/or replacing this cable may be necessary as it may have became damaged or have an intermitted short.
