C1038 Timing lag error on LabJack channel

[sagha]

I'm getting a "C1038 Timing lag, data acquisition stalled." error on my LabJack channels. I have 4 LabJack channels configured as A to D and every few minutes, the C1038 error occurs. The DAQFactory project hangs (the cursor turns into the blue circle and then the project screen goes blank). I tried increasing my sampling time from 1 to 10 seconds and I am still seeing the same problem. I see the timing error on all four of my LabJack channels. The other channels in my project are the result of parsing a string read over UART that is received every 1 second.

I've attached a screenshot of the Command/Alert console and my channel configuration.

That is a bit odd. You aren't polling very fast at all.  I would start by double checking that you are running the latest LabJack UD drivers and firmware.  I'd also set the Timing of all 4 of my channels to the same.  There is no advantage of reading them at different timings unless you really need that, in which case I would consider setting the Avg? column and average 1 second reads down to whatever rate you want.

I had loads of timing problems due to a wireless network.

You have not said how you are connected... Usb, ethernet, wireless?

If you are using a wireless connection anywhere I'd also check that.

The LabJack is connected over USB

[AzeoTech]

Following that same suggestion, I would make sure the LabJack is alone on the USB hub.  You might be getting interference from other USB devices, one of the many reasons I dislike USB connections.

There’s no USB hub. It’s plugged directly into the desktop.

[AzeoTech]

Alas, the desktop probably has a hub internally, so most any USB device could be interfering.   After updating,  I would contact LabJack support for some input as this is most likely on their side.

The other thing to consider is if the USB port is USB-2 or USB-3. USB-3 being the later standard and of course faster.
