We shut down our API3200 to move from one bench to another but now when trying to bring it back online the software does not communicate with the MS, it will communicate with the HPLC Pump and Autosampler over serial but the MS it does not detect. I have replaced the GPIB cable but that did not help. The faults lights are both steady on (red and green), but I have not found in the manual what that might indicate. Just wondering if anyone else that uses the Sciex instruments may have seen this before.

Thanks for any information.
