Hi,

I seem to be having problems with the dEX v1.50.012. There seems to be times when the dEX doesn't generate the code it is supposed to. I've faced this problem on several occasion when using this dEX version.

For instance, I wanted to use a temperature sensor with resistive output. Whilst it would read without problem using the normal 2-wire resistance setting, the readings would go out of range once I applied a span to it. Upon checking the code, I noticed the problem. The code changed as below. I had to enter a manual channel, and key in the "I,2W" setting. Only then did I get the reading.

1R(I,2W,"Resistance_10~",=1023CV,LM,0,NA) -----> 1R("Resistance_10~",=1023CV,LM,S1,0,NA)

Another time I tried to read an input of 4-20mA, using external shunt of 510ohm. But the dEX would not allow me to change the input from 30mV-3V to 300mV-30V. I ended up having to use the manual channel again.

Could you have solution to this? Like say, downgrade to the earlier dEX version?

Hi arivan,

Sorry for the inconvenience, we noticed some interface issues within dEX v1.50.012 which caused that error.

For solution, you may need to use native language through command interface or if you prefer to use dEX you need to downgrade your firmware to 9.10.

I will send you the link to download the previous version of firmware to your email.

Hi Rudy,

I've received your email. Thank you very much.

Hi,
I'm seeing the same problem. This has never happened before.

I regularly calibrate RH sensors on my set-up. Yesterday when doing so DEX assigned the wrong channels.

I use shared voltage terminals on channels 15 and 16.
On DEX I have always assigned the sensors to these channels: 15V for RH1, 15+V for RH2, 15-V for RH3, 16V for RH4, 16+V for RH5 and 16-V for RH6

I've cleared the cache, deleted all jobs, carried out a hard and soft reset and rewritten the program but the same thing happens.
Nothing has changed on my system.
Any ideas?
Thanks,
Dan

This is how DEX sent the program to the DT85 (series2):

Hi Dan_Lew,

Please upgrade your logger firmware to 9.16 version.
We have several interface issues on 9.14.

Best regards,
Rudy Gunawan

Hi Rudy,

I've upgraded the firmware with the same results. All previous jobs and cache cleared.

Dex still does not input the correct shared channels.
Info shown below.

Any ideas?
Thanks,
Dan
