smarquis Posted May 25, 2020 Share Posted May 25, 2020 My process give me an error. D0004_1009 GENERAL ERROR. WRITE ERROR When I click on the OK box, a second box appear and say that the labjack is lost. I can't generate manually this error. It appens randomly. My process is very simple. my computer is connected by a good quality USB cable to the labJack. The Lajyck is used for data logging (pH and pO2 value) and connected to a ME-UBRE Relais box. The relay box activate some pump and electrovalves. Any ideas about fixing this problem? have a nice day Stef Quote Link to comment Share on other sites More sharing options...
AzeoTech Posted May 25, 2020 Share Posted May 25, 2020 I would start by making sure you are running the latest firmware and drivers from the LabJack website. After that, I'll let the folks at LabJack chime in as the error is coming from their drivers. Quote Link to comment Share on other sites More sharing options...
LabJackSupport Posted May 26, 2020 Share Posted May 26, 2020 Which LabJack are you using? U12, UE9, U3, U6, T4 or T7. See related information here: https://labjack.com/support/app-notes/usb-communication-failure My first suggestion would be to remove the relay box from the system and see if the problem goes away.
