Decided to crack open my DEG1 GPU OCuLink GPU dock. They're advertised as having a "signal amplifier" but I wanted to see if they were retimers or redrivers.
Turns out that they are P13EQX16612 redrivers:
They also include a cable but don't advertise this, at least not in an obvious way.
But the more interesting part is that there are also 3 switches on the PCB, which are not present in the STH review.
Unfortunately, the switches are quite fragile. As you can see, I broke off the "DEBUG" switch's slider trying to manipulate it. Fortunately, that just means that the switch is stuck in the "A" setting, which was how it came from the factory.
The second switch is "FLLOW START". Normally, the auto start/stop seems to only work reliably with Minisforum computers. When flipped this to "ON", it actually got it working with my generic PCIe to external OCuLink adapter. So, if you're having issues, I'd recommend flipping this switch (just be careful not to break the switch).
The third is "TGX" which as far as I can tell is Lenovo's version of OCuLink. Not sure how it differs from standard OCuLink, but the switch seems to be in the "ON" setting by default. Guess it doesn't hurt anything to leave it on?
