r/homelab on Reddit: Cisco rj45 to usb console cable diy - garbled transmission
November 16, 2023 -

Hi, I followed the cisco Pinot and used a usb to TTL converter. I cut the connector off of a cat6 cable and wired it up to the usb to TTL converter.

I am using 9600 8N1 with no flow control and am getting garbled text from a brocade icx-6610 and also an HPE Poe+ switch. So I am assuming it's something to do with the converter?

I do have an actual cisco rj45 to usb cable coming to test but, I don't understand why I would be getting garbled text, like a bad baudrate setting.

I have tried several baudrates, most give garbled text. I have tx, Rx and gnd hooked up (CTS, RTS isn't needed it says, I did test with them connected but it made no difference) and am using minicom as an emulator.

Any thoughts or ideas?

DIY Cisco RJ45 console cable?
No. The cable you linked is a USB to TTL cable. IIRC the Cisco rollover cable is akin to a null modem (i.e. the pinout on one end is reversed, hence the name "Rollover") RS-232 cable. You can hack a RJ45 cable (Google "Cisco Rollover cable pinout") and solder it to a DE-9 (again search for "serial port pinout") connector, then you'll need to get a USB to RS-232 adapter and plug your newly made cable into it More on reddit.com
