Tek DPO4000 / MSO4000 console port pinout?
(1/1)
Jwalling:
Hi,
Does anyone happen to have the pinout for the console port on a Tek DPO4000 / MSO4000? I believe that it's J501.

I've PM'd him, but so far no reply...
This DPO4034 doesn't even get the splash screen. Code appears to be executing from the boot flash. All internal voltages are good.
Thanks!

Did you find out where the serial console port is located?
I have a similar issue with a DPO4054 :palm:

Never heard back, I ended up selling it for parts.
Still would love to find out, though...

Sorry for reviving this old thread but it was never officially answered and I wanted future users to have less of a headache finding the answer. This is the most straight-forward thread on the subject.

I confirmed this worked on my MSO4104.

This post also contains an image of the connector, and documents ground as the third pin.
