Hi, I received a new Tracker. The I/O thru 8 pin connector is not functioning as it should. It charges if connected, but I am using the Digital IO and it will not read the digital inputs. I have same code on 35 units and have tried different M8 cables. S ---

Did you enable [CAN power](https://docs.particle.io/firmware/tracker-edge/tracker-edge-api-reference/#enableiocanpower-tracker)? This also controls the GPIO/Serial/I2C pins on the M8 connector. It defaults to off and the M8 connector I/O pins are isolated when off. ---

Yes it's enabled in code ( like other 35 units running same code) . Stew ---

If it's only the one tracker that's affected, you should use the [support portal](https://docs.particle.io/troubleshooting/troubleshooting/) to generate a ticket, which could involve an RMA or refund depending on the circumstances. ---

Its only one out of a two batches ( maybe 10 in total ) but I have only activated 4 of them so far ---

If you have the ability to inspect the CAN\_5V on the M8 connector, it would be interesting to know if that's being powered. It might be a clue to whether it's a problem in the isolation or the boost converter. ---

I see 5V on the CAN\_5V Stew ---

Rick The support portal link does not offer an option for returning equipment. Where exactly do I look to get this resolved ? Stewart ---
