🎓 Reddit experts on logic analyzers
The comments and opinions expressed on this page are written exclusively by redditors. To provide you with the most relevant data, we sourced opinions from the most knowledgeable Reddit users based the total number of upvotes and downvotes received across comments on subreddits where logic analyzers are discussed. For your reference and for the sake of transparency, here are the specialists whose opinions mattered the most in our ranking.
Voltage is important. You could be looking at "real" RS232 or something like TTL/CMOS UART. Additionally, there is no guarantee that the pins will be wired as they are in the cables you linked (especially if going to JST). Best practice would be to check ground continuity (while off) and voltage levels (while on) and use a logic analyzer on the inputs (eg. Haven't used this exact one, but it is a popular Chinese clone https://www.amazon.com/HiLetgo-Analyzer-Ferrite-Channel-Arduino/dp/B077LSG5P2/ref=mp_s_a_1_1?ie=UTF8&qid=1555138013&sr=1-1&pi=AC_SX236_SY340_FMwebp_QL65&dpPl=1&dpID=41wZsMYKyUL&ref=plSrch). Note that if you do find voltages in excess of 5 v, you are probably working with spec RS232 voltages and you should use a different logic analyzer than the one that I linked.
There's a similar one on Amazon with excellent reviews:

That is more than a cheap knockoff, they even stole the original products name/trademark. They should be reported and removed.
I would recommend Zero Plus because it has internal sample memory and a higher sampling rate.

I was about to say the same thing, I had the opposite problem where my code was too slow and removing debug flags made it much much faster. This is probably your issue. And you're going to want a logic analyzer for doing embedded work.
If you need a budget analyzer try this one:

It works well with both PulseView and Salaea.
