I like it, will probably buy when they finish open sourcing the code

What exactly does this do?

Huh, so you connect your display, mouse and keyboard to this thing, which is in a pcie slot of your current machine, and you can somehow switch it to every machine in your (local) network?

I guess you need a vnc server or something similar running on all hosts?

[-] c10l@lemmy.world 5 points 7 months ago

Not quite. You connect this to your network, then you can remotely connect to it and control the computer it’s attached to. This includes sending ACPI signals, accessing the BIOS, etc. so it’s as though you had physical access to the machine, only remotely.

Barring actually pressing buttons, of course.

This is inspired by PiKVM. https://pikvm.org/

Ah, that makes more sense. Thanks! Sounds really useful for those hard to reach machines. (This could have helped a lot during the CrowdStrike fiasco, I guess)

[-] c10l@lemmy.world 1 points 7 months ago

Indeed! My use case is so I can fix my home lab computers when I’m away.

The PCIe connection is only for supplying power to the device. This form factor.makes it easy to place it inside the Computer. Then you only need to connect HDMI and USB and you can remote control the connected device.

There is another version that is designed to sit outside the computer case already.

[-] sir_pronoun@lemmy.world 1 points 7 months ago

Oh, so it takes the HDMI signal from the computer as input, and it outputs USB keyboard/mouse events?

[-] ShortN0te@lemmy.ml 1 points 7 months ago

Yes. You can even mount files and images through USB.

Bought it. (The external version). It’s bit buggy

[-] c10l@lemmy.world 1 points 7 months ago

What's the use case for PoE? If the mobo can't supply energy, there's not much you can do via this device, right? What have I missed?

[-] UnpledgedCatnapTipper 1 points 7 months ago

The network port on the KVM will connect to a switch (which can provide PoE, potentially), not to the device it's managing.

[-] c10l@lemmy.world 1 points 7 months ago

Sure but if there's no power on the mobo, the device can't do anything. Even if it sends an ACPI on signal, there's no power. 🤷

[-] UnpledgedCatnapTipper 2 points 7 months ago

Pretty sure you still connect the kvm card to the motherboard power button jumpers so you can power on the computer remotely. That's how the non-pcie version does it.

[-] Player2@lemm.ee 1 points 7 months ago

At least you would know that the KVM is responding even though the computer is not, so it's more likely a hardware issue than a network one
