BMC console com2 on Talos II
atomicdog:
There are a few issues. The connection should be RS232 not TTL. So you need a USB to RS232 adapter not USB to TTL.
I tried my USB/TTL and got the same result you did. So, I checked the schematic and noticed it shouldn't be TTL and also the pinout in the schematic is different from the manual.
In the manual pin numbers alternate rows. So, ground is the bottom right most pin9 (pin 5 in schematic).

For the record, this is how mine is hooked up: basically one of those 10 pin to DE-9 headers, and then a regular USB serial connector. https://www.talospace.com/2020/04/what-to-do-when-bmc-wont-talk-to-you.html

I have the DIGITUS AK-610300-003-E. But until today I haven't needed it yet.

Wow, OK so I hope that for others this thread helps to understand type of cable and connection needed for COM2 J7701 on the Talos II board.
* It is not TTL and following the manual pinout and using a TTL/USB might give you false hope
* Pin out is incorrect
It is DTK/INTEL DB9M to IDC10 which is part number 07121 from pccables.com
Use with a RS232 serial cable with a null modem.
Thanks!
After that I was able to interrupt the boot and can poke around. Unfortunately it does look like the BMC root password is no longer 0penBmc though, so that will be the next step for me.

I do not have the slip of paper. :o
MPC7500:
Why don't you have the paper with the password? It's in the mainboard box. Is the Talos used? If yes, I would ask the seller.
