Is There A Cable Product Verified to Work for the Console Port on Pylontech US3000?

My distributor and Pylontech themselves couldn't do me the deed of furnishing the debugging cables (the so-called USB- Male rs232 and Female rs232 - RJ11)

So I went ahead and contacted another Pylontech reseller here, and they said to just get those cables from a computer store. So I went on to mercadolibre and bought them. Turns out the female rs232 - RJ11 was the only offering of its kind available online in this country. I don't have the knowledge or gear (or electrical chop shop) to see if my cable(s) is the problem. But everytime I try to connect it has a timeout error. I know I'm using the right COM port. The Pylontech US3000 manual says baud rate for RJ11 needs to be 1200. Really don't know what else to try.

@AgroVenturesPeru

US3000 uses CAN to connect to a victron system. The guidline is linked by @kevgermany . And the cable uses RJ45 plugs not RJ11 or the rs232 protocol. You can make up the cable yourself if it cannot be purchased. There is also a wiring guide.

Why do you need debugging cables?

If you connect each battery one at a time to a GX with the correct can Battery type you should be able to see what it is doing.

Are you having hub issues?

You'll pretty much have to make this cable yourself. Search Google images for "Pylontech RS-232" and you'll be presented with diagrams of how to make your own. Most of the images show the RJ11 setup that you'd need for US3000.
Then use a standard USB - RS-232 cable if your computer does not have a RS-232 port on it.

Here is a link to a forum which shows a DIY cable:
