I did. That's to say it was RS232 to I2C. I used a MAX232 and a PIC16F73.
For RS422 you will need differential drivers/receivers p.e. MC3487/86. For
the processor a PIC16F873 may be a better choice as it's newer. You will
need to check what protocol is used at the RS422 side. Is it asynchronous,
SDLC, HDLC or another one? You also need to look wether the I2C side has to
be master, slave or both. Unless you have a proper specification of the
protocol and the data format, you will run into a lot of problems.
