There are several primary types of DB9 connector pinout schemes that we will review in blog post. ... First, we will take a look at the DB9 connector pin locations for a male and female DB9 connector.

DB9 (Male and Female) Standard Pinout
DB9 (Male and Female) Standard Pinout · Always identify proper wiring via continuity check & color when using multi-strand cables. The calibration certificate for the device should be used as the definitive reference for custom wiring options. Note: Do not connect RS-485 to RS-232 units or cables.
DB9 to RJ45 serial connect to switch - correct pinout?

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
Better DB-9 to RJ-45 solutions?
Thankfully as time has passed, those have gotten a lot more standardized. It’s rare to find anything these days that isn’t the Cisco pinout. Most new stuff is just USB which is even better. But vendors who use USB connectors without putting USB on the port annoy the crap out of me. More on reddit.com
Does a cable with DE-9 connector on both ends work for both RS485 and RS232 interfaces
For 485 I think you need a resistor at both ends. More on reddit.com
Making a DB9 serial cable from two Cisco console cables
Two of those blue cables, coupled together, will give you a straight-through serial cable. the biggest problem that I see is that a DB-9 connector has 9-pins and an rj45 only has 8 contacts. Does the missing pin not matter? The missing connections only matter for a modem. More on reddit.com

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?
