The Python code was just for prototyping, but it was perfectly functional; if I hadn’t needed the C implementation I would have stopped there. Rpmbuild Does Not Appear To Be A Spec File more. I don’t think that there was any further refinement in the C implementation step. I have to admit that I didn’t even think to ask for an official protocol specification, I just jumped into reverse engineering.

View and Download UNI-T UT81B operating manual online. UT81B Multimeter pdf manual download. UT81B Interface Program by DMM. Versions: 1.0. File name: UT81B.exe. Dec 21, 2011 I am so frustrated by the UT81B software, that I was going to write my own. Few years ago when I bought this meter I asked the UNI-TREND for.

In my defense, the existing software and documentation were so bad that I didn’t even hope to get an answer. And now, checking the protocol spec you got, I see I was not too wrong anyway;P. For example, in my description of the protocol I talk about the value 90 being duplicated whenever it appeared in a packet.

I tried just now to find the explanation for that in the spec, and I only found a cryptic passage which talks about “X5A” which probably means 0x5A, which equals 90. But I would never guessthe meaning from the text itself Also, that spec doesn’t say anything about timing and packeting and such. Anyway, good luck. All of this was long ago, but if there is any doubt in which I could help, let me know.
