How to: USB RS232 to RJ45 interface pinout | Hardware Canucks

What you actually want to do is take the Serial pin out listed on the Ebay page, and convert THAT to RJ45, with the included FT232R chip. Without that chip, you're simply not going to get it to work via straight cabling. If you DO get that wire, you can cut the end off the RS232 side and put on a RJ45 and have it work by wiring a DB9 pinout ... More on hardwarecanucks.com

DB9 to RJ45 serial connect to switch - correct pinout?

This pinout worked for me: RJ45 -> DB9 RTS 1 -> 8 CTS DTR 2 -> 6 DSR TXD 3 -> 2 RXD GND 4 -> 5 GND GND 5 -> 5 GND RXD 6 -> 3 TXD DSR 7 -> 4 DTR CTS 8 -> 7 RTS IIRC, I had to leave one of the ground pins unplugged. http://i.imgur.com/O3RRKQC.jpg *Edit: Here's another picture for clarity. Also, you can push the pins back out with something like a small flathead screwdriver (~1mm). http://i.imgur.com/7hWniXb.jpg More on reddit.com

Confused about proper pinout with an RJ45 to DB9 adapter

The device has a control box that accepts RJ45 cable. I am sending my commands via a Global Cache iTach WF2SL device which has a DB9 serial port. I am attempting to connect the two devices using a Cat-6 T-568B cable, and a RJ45 to DB9 adapter. The WF2SL pinout uses 2 - RX, 3 - TX, and 5 - Ground. More on community.spiceworks.com

r/networking on Reddit: Pinout for serial cable with RJ45 on both sides?

December 4, 2015 -

We have a ThinkLogical Serial Console Server that I'm attempting to connect to some F5 Big IPs. Both devices have RJ45 jacks, and I'm trying to get them to talk to each other. The Big IPs came with TIA 568B to rollover adapters.

Connecting using RJ45 -> DB9 works just fine.

I've tried connections between the SCS and Big IPs with the following, in all permutations:

With and without the adapter. EDIT: Meaning with rollover and standard pinout ethernet cables.
DTE and DCE on the SCS.
Multiple baud rates on both sides.

Nothing has worked, so I can only conclude that the pinout is the problem. Does anyone know the correct pinout that I should be using? My google fu has failed me.

EDIT: Just in case someone finds this while searching for the same problem, here's the answer: my coworker accidentally used an F5 failover cable instead of standard ethernet. The failover cables have their own unique pinout, so they didn't work. The correct cable for this job is a standard rollover, or a standard ethernet cable with a rollover adapter (which is included with the Big IPs).

We also had to change our serial console server from DCE to DTE, turn off all flow control, and (obviously) match baud rates and parity on both sides. The Big IPs default is 19200 8N1.

Did you try a regular ethernet cable? Not a crossover.

I ordered a DB9 to RJ45 converter so I can connect to old switches with DB9 female connector.

I ordered two, but I failed the pin-out on the first one. And can't pull back plugs once they're pushed in. Does anyone know the correct scheme to get this working with an old HP 3500 switch to be specific?
