the file header shows a U9 device despite I use a U6 device.The range shown is not correct

13, CH+=13, CH-=199,
UE9 Range=+/-5, y=n

14, CH+=14, CH-=199, UE9 Range=+/-5, y=o

15, CH+=193, CH-=199, UE9 Range=+/-5,
y=p

Each value is stored twice.

Channel 0 is listed as v0 in colum B and as yo in colums R

Channel 1 is listed as v1 in colum C and as y1 in colums S,

and so on...

I see the mistakes in the header and will fix in LJStreamUD V1.10.

The reason you see channel 0 listed twice is that v0 is the raw voltage and y0 is the scaled value.  If your scaling equation is y=a then these columns will be identical.

Hello,

I am a new user of the U6. I need all 14 AI channels (single ended) and 16 DI with am max sampling rate of at least 1000 Hz per channel.

When I start LJstreamud 1.06 it shows an normal number of the internal temperature (295 deg) and nonsens on the channel of the digital inputs (-10.457.. ). When I start streaming, the internal temperatur jumps to 429 deg and the DI shos the correkt value.

What does the number 199 in the colums -CH mean?

When LJStreamUD is not streaming it is acquiring data in command/response mode.

Channel 193 currently only works in stream mode, but will update soon with command/response support.

The U6 internal temperature sensor does not work in stream mode.  It takes too long to settle.

Thank you very much for your answer. So my U6 works correct. I am very happy how it works on my test bench.
