RS 323 Support with an Analog PI Design?

[Christian]

Hello,

I'm having a large coil analog PI system (Ebinger Upex similar to a TB Electronics Pulse Star II) and wondered if it would be possible to add a RS 322 interface to it for logging data and GPS data?

Thank you,

Christian

Hi,
if you have analog output you need conversion to digital before pass stuff to the RS-232.

Suitable things could be :

-SAMPLE/HOLD ic (optional) like LF398
-ADC ic (if with S/H you don't need it in separate ic)
- an MCU with usart support like some PIC16F628
- a level shifter ic like the MAX232 (or MAX3232 depending on MCU)

In simplified measures (not great resolution or hi-speed) you could avoid some stuff using just:

- an MCU with internal (say 10bit or more) ADC like some pic16F877
- a level shifter like max232

Then you have to program a textual interface between PC and the program running on the MCU...

That's it. That way you could ask MCU by RS-232 to collect data and transmit to PC with a command like "SAMPLE"... then also program the MCU for collecting multiple samples (using internal memory) and then send to pc etc etc etc

So, sure it's possible... but implementation depends on your needs.

Best regards,

Hi Christain, The Deeptech has an rs232 output built into it. So can read some on it here and follow the link to the site. I may be a distributor here in the state. We are still in talking about it. The logger is being tested on the detector now and will have a report soon.
