[geeks] RS232 / RS485 opto-isolated converter

[Patrick Giagnocavo]

I have a number of Carel brand, RS232-RS485 opto-isolated converters,
cheap!  No power supplies, but they take 12V with what looks like a
typical plug.

RS232 is DB25 female connector, RS485 side is both 3-wire and what looks
like an RJ45 style jack connector.

What exactly would they be used for?  I have no idea what you do with an
RS485 "network" ...
