There is no standard for color codes. The chart you found seems to be using the resistor color codes, but shifted by 1 for some reason.
You're just going to have to "buzz out" the connections one-by-one using an ohmmeter or something.

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.

I am attempting to control a device with RS232 commands.
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.
The control box expects what is in the image below:
Screen-Pinout462×336 35.3 KB
The adapter has the following pinout definitions:
Adapter Diagram831×771 47.9 KB
I’ve been trying to research this to determine the correct pinout but have become pretty much completely confused at this point.
I have ensured that the WF2SL is configured with the correct baud rate and additional settings.
I have tried quite a few different combinations of pinouts with no success.
Would anyone be able to dumb this down for me, and help me get the right pinout on the adapter, using the Cat-6 cable I have, to work with what the device is expecting?
Thanks in advance.

r/networking on Reddit: DB9 to RJ45 serial connect to switch - correct pinout?
July 27, 2017 -
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?

There is a DB9 Pin Removal Tool . I don't know if it helps you but now you know. I agree w/ DataX as far as the pinout.

RJ-45 to DB-9 Serial Port Adapter Pinout Information | Juniper Networks
The console port on a Juniper Networks device is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a laptop or a desktop PC. If your laptop or desktop PC does not have a DB-9 plug connector pin and you want to connect your laptop or desktop PC to the device, use a combination of the RJ-45 to DB-9 socket adapter along with a USB to DB-9 plug adapter.
