enjoy the pin configuration below !
A DB-9 connector uses four wires (two pairs) for token ring networking:
Pin 1 - Red - Receive +
Pin 5 - Black - Transmit -
Pin 6 - Green - Receive -
Pin 9 - Orange - Transmit +
A RJ-45 connector is an eight wire twisted pair cable:
Pin 3 - Blue/White - Transmit -
Pin 4 - White/Orange - Receive +
Pin 5 - Orange/White - Receive -
Pin 6 - White/Blue - Transmit +
RJ45 DB9

Subject: Token Ring cabling question
I have never used token ring so I apologize if this question is rather
simple.
I have a 2502, 2513 and an IBM MAU model 8228. I did not buy the black heavy
cables with the MAU but I was able to find them on ebay today, of course I
had to purchase another MAU to get the cables. I understand these cables
have a RJ-45 connector on one end, is that correct?
Now the routers being DB9 connectors, I have two little gizmo's that are DB9
to RJ45. I assume I can use a connector to connect the RJ45 from the MAU to
the RJ45 from the routers?
I searched the archives and I did find something that sounded like this
would not be a problem but I wanted to make sure I was reading it correctly
and if I needed different cables I was hoping to find out what those would
be so I could find some.
TIA
go
