Are there any tutorials on logging rs232 data to an SD card? I work with fire alarm panels and need a way to log the rs232 printer data from the fire panel to an SD card for later viewing. I can figure anything out with tutorials but I don't know anything about rs232 communication, how it works, or if this can even be done. Any help would be great.
Thanks

Re: rs232 Data Logging
You would start looking at rs232 to TTL converters like the max232. Once you get the levels to 5v you can work on getting the data into a micro like the Arduino and then into the logger.

Re: rs232 Data Logging
Simplest would be an older Serial Arduino and the Adafruit SD/RTC logger
shield.

Adafruit SD/RTC logger ......

Then it's just a matter a writing some code to log the data the way you would like to see it on the SD card.
