RJ-45 to DB-9
RJ-45 to DB-9
(OP)
I've got an older switch that has a serial connection to it, however, I do not have a serial cable for it.
I do however, have a serial to PS/2 convertor and tons of RJ-45 cable.
I just don't know what the pin out would be for putting the RJ-45 to my femle DB-9 convertor.

I know I've seen others but I don't have them handy right now.
You have eight wires in the RJ-45 so you'll have to drop one pin. Losing pin #1 (shield GND) is only mildly risky; if you have a shielded RJ-45 you can run it on the outside.
I suggest monitoring your signals with a break-out box; you can probably get away without routing one of the handshake lines. It all depends upon your application.
OTOH - There are lots of inexpensive RS-232 cables available on the web. Is this project worth saving a few dollars?
RE: RJ-45 to DB-9
On the RJ-45 side, these will corrolate to pins 3,6,and 4 respectively. If you use a RJ-45 to DB9 adaptor, this will be the Black, Yellow, and Red wirs in the adaptor.
