rs232 Data Logging

[swallace23]

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

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.

Simplest would be an older Serial Arduino and the Adafruit SD/RTC logger
shield.

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.
