GC-MSD Communications Error

Hi there, 

 

I've recently been having a problem with one of our GC-MSs losing connection at random. 

The error in the MassHunter logbook is "Communications Error: Download Command Timed Out (MSC:SENS?QUAD), and a cursory google hasn't brought anything up. From the look of the error, it could be something with the quad sensor?

 

The connection usually drops whilst the instrument is idle, anywhere from five minutes after a run, to around 14 hours at longest, but it has also dropped out a few times during runs, bringing sequences to a halt.

Unfortunately, the PC controllers are air-gapped and isolated, so screenshots will be problematic. 

 

Has anyone encountered this error before?

  • Hi icg-001,

    Take a look at the power saving options in windows control panel to make sure that the PC is not set to sleep at any point. For a deep dive , you can edit plan settings and make sure the Hard Disk is not set to sleep. PC activity is measured by keyboard and mouse inputs, instrument control software may not have enough activity for the timers deactivate.
