Re: RS232 Datalogging and Control

I would say take a look at National Instruments. I used them several
years back to control an environmental test chamber using a combination
of GPIB and RS-232. It was great! They have a lot of expertise in
data acquisition and control software. The learning curve is a bit
high but if you can afford it their software cuts these kinds of tasks
down by 2/3rds. They have a kind of Graphical based programming
language which makes it fairly easy to program. Also, if you must, you
can write your own code...I think you can write it in C but I'm not
sure.

you can find them at www.ni.com

GOOD LUCK!

Unfortunately my expertise in this area is somewhat out of date.
MS Hyperterminal doesn't look capable enough, OK for logging data but no
programmable capability.

My question is, is there a datalogging program available that also allows
ascii characters to be sent to addressable instruments, in order to (a)
control the oven and (b) log data from the DVM without programming?

I imagine writing a program in some language, possibly Visual Basic, is the
way to go but that'll get me bogged down in learning a software language.
However, if I can't buy in suitable software I'll just have to learn VB, but
does anyone know of such software?

thanks,

Andy.
