I've done similar. RS485 to RS232 converter. Used to capture RS485 data.
Used a scope to find the data rate and wrote the converter software to
simply package up the received RS485 data and send out as RS232 for logging
on a PC. You end up with lots of data but making sense of it is another
matter. I had part of the original protocol document and needed to fill in
the gaps so it was fairly easy.

If you need general RS485 info or need to purchase an RS485 to RS232
converter try www.rs485.com . Best site on RS485 I've ever found.

Good luck
