DB-9
Actually, that should be DE-9. DB-9 is used by those who don't know any better. The "D" refers to connector type, the 2nd letter the shell size and the number refers to the number of pins. So, the old 25 pin serial connectors are DB-25 and the 9 pin, DE-9.
BTW, at one point in my career, I used to order connectors by the hundreds. I wouldn't get very far ordering the wrong item.

What does the RJ45 end connect to?
We could also argue that it is not an RJ45, but an 8P8C connector/jack.

@jahonixGuys do any of you have a working console cable? If yes then can you post a picture of it ? Moreover, can you post an up close zoomed in on the pin layout of the Rj-45 connector? So, I can take notes and create a new connector?
-
It depends on how the port in your device is configured. You will need the documentation for that before anyone can help you.
-
Beyond cable incompatibility, I'd probably try 9600 and 19200 baud as well. Then again, I might just SSH over IP and call it a day.
-
I have a few for Cisco, but they are DE-9 on one end, not USB. Regardless, a picture won't tell you anything. I have used cables for Cisco, Adtran and Ciena and they weren't compatible. You need to find out the connections required for your device and compare it with the Cisco pin out I provided.

RJ45 is valid, as it refers to a registered jack type. 8P8C is the connector used with it. On the other hand, DB-9 doesn't exist, at least not in the commonly used connectors.

These colors are not standardised so from viewing at it we know nothing.
You must provide the pins of the RJ-45 jack from your device. -

And what does it help with the actual problem if it's DB or DE? We are not a micron closer to a solution.

Pin layout is present.Couldn't find any details about the RS-232 (RJ-45 like) plug :
@smrehan00 : your turn.

This is the cable pin out that I have on the cable I bought.
As has been said several times, there is no standard connection. I mentioned 3 brands of equipment, which all use different configurations. For us to help you, you have to provide the connections as required by your device. We simply don't know. Is there not any documentation for that computer that tells you what's required?

@JKnott There is nothing in the manual which shows about the pin status of console port. I will check in the system bios to see if the console port is activated via BIOS.
-
?? You actually bought a device with very needed peripherals that are not documented (and probably not standard) .... it's time to contact their support.
Was the device sold with an optional console cable ? Your next best choice : get this cable. -
Well, then you'll just have to start checking to see where what is. The Cisco connection is a good starting point. Years ago, we used to use something called a "breakout box", which made it easy to test individual pins or make appropriate connections, etc.. If you have a volt meter, you can probe the pins to see which ones have voltage on them. The transmit data will be a few volts and the receive line may have a fraction of a volt on it. You can also do a continuity test, to see which wires are ground. This is something that I have done, on many occasions, to test unknown connections. You can make your own "breakout box" with a couple of RJ45 to screw terminal blocks.
Does the manufacturer of that computer have any support available? I have been browsing the Pondesk site and don't see your computer.
-
I just noticed the Pondesk site has live chat available. You can go there and ask about that console cable.

Let's to put my 5 cents in discussion:
At the first You need really well engendered USB-to-serial DB9 converter: Prolific PL2303 (or it’s advanced version PL2303ta).
“Well engendered” mean “compatible with most hardware serial interfaces which hardware manufacturer used”, no matter Cisco, Juniper, or some crappy no name router.
Only after that a You need to make next step forward.

That box requires an RJ45 connector, not DE-9. If he had a DE-9, he'd then need a DE-9 to RJ45 cable. What he absolutely must do is find out the correct connection for that box. He can do that by contacting the manufacturer, as I mentioned.
We can't be expected to guess what that box requires, when there's so much variation in those cables.

Of course, You need additional DB-9 to RJ-45 extender cable.
And mostly because only a few USB-to-Serial converters have a cable more than 0.8-1m long. Admins confirm to You that common length 1.5-2.5 m would be comfort in any situation.

Why does he need a DE-9 (yes, that is DE-9, not DB-9) anywhere? He has a USB port on a a computer and that box needs an RJ45, with some serial connection. Hopefully, it will be Cisco compatible, as that is what his cable appears to be.
I have an adapter with a DE-9 and I then have to use another cable to connect to Cisco gear. I needed a different cable for Adtran and yet another for Ciena. That's what makes this so much "fun".
However, until the OP contacts the manufacturer to find out what's needed, we are only guessing. As he mentioned, there might also be some configuration needed to even make the console work.
