@Andrewier....Thanks for that, very well put, I'd forgotten about VGAs.  I guess there  is some sense to it.   Are you sure about DB-31 - I remember seeing a high denisty plug the sdame size as a DB-25 but (like a VGA) with 3 rows of pins, but there would have been a lot more than 31 there....

@David Ashton

I am not sure if we are talking about the same (or my bad English is tricking me), but... let it go:

If the matter is DB x DE connector designations, the first letter (D) is for 'D' type (or trapezoidal), second - A,B...E is for shell size and the number, for the number of pins, of course. For example, we can have DB25 and DB31 - same shell size but different number of pins. The same for the - once ubiquitous - DE9 (PC serial port) and DE15 (aka VGA) .

Regards,

AW.

Got them all- I guess I must be an instrument guy. LOL.

I'm not convinced you can't use type B below 0°C but it has a nasty hook around there where it reverses slope, so a given mV can map to more than one temperature, and nobody that I've seen has bothered to measure the mV below 0°C (the only reason to use such a nasty Pt-Rh thermocouple is if you have to go up to very high temperatures (>1500°C)).

Sheetal (and everyone else).

I used up my one and only set of questions that were already done. I will tyr to run them one in awhile and perhaps you can help. Please send questions to me at martin.rowe@ubm.com. I'll compile them and post.

Thanks as always Martin.  Got 3/5 - came short on the language one and no 5.  Should have known better on this one as I have come across it before.  Silly idea though, if they have a unique letter, what's the point of putting the number?

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
