Hi all. I'm working on a board that has a specific use at the moment,
but I'd like to leave things a bit open for other future uses as well.
At the moment, there will need to be a connector that talks to a
device via RS232. It's low speed (9600bps) and short distance (under
10 feet, likely under 3 feet). To keep my options open for the future
(and to aid my design), I'd like to use RJ45 connectors to carry the
RS232 signal. There is a standard for this (EIA-561, mentioned here
about 25% of the way down the page, but I've seen it elsewhere as
well) so I feel ok setting it up. I believe that the original intent
was to use telephone style cable with these RJ45 connectors. What
would happen if I used straight through CAT5 ethernet cable?
Electrically I think it'd be ok, and since RS232 isn't a differential
signal the pairs shouldn't have to be matched.

How wrong am I?

:)
