Cant connect Oak-D-SR TOF POE

JoshTheKnightWhoSaysNICapogna

I cant seem to be able to get my TOF camera to connect to depth AI. i also cant ping the camera at 169.254.1.222.

I'm connecting the camera via a poe hub. Hub lights are on. Camera purple light is on.

This is my first time running the camera.

Config:

PC - windows 10

IP: 169.254.12.10

sub net: 255.255.0.0

Dns: not configured

Thanks!

That's a link to the documentation that's supplied with the camera. I have already looked through it and I did not find anything helpful. Is the something specific I should be looking for? The POE switch is unmanaged if that helps.
Other POE cameras (Basler, Cognex) connect just fine.

Also tried reflashing the bootloader. no change.

looks like flashing was successful:

Booting latest bootloader first, will take a tad longer...

When depthAI opens I get the following:

C:\Users\Admin\AppData\Local\Programs\Python\Python312>python -m depthai_viewer

Hi JoshTheKnightWhoSaysNICapogna
Could you try one of our examples, since the bootloader connection works:
https://docs.luxonis.com/software/depthai/examples/rgb_preview/

Thanks,
Jaka

JoshTheKnightWhoSaysNICapogna

I'm not sure if that will help as I cant even ping the device but I did run the script and got the following error:

Python 3.12.6 (tags/v3.12.6:a4a2d2b, Sep 6 2024, 20:11:23) [MSC v.1940 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license()" for more information.

What other diagnostic data can i give you to help debug this quickly?

JoshTheKnightWhoSaysNICapogna I cant even ping the device

But you flashed the bootloader to it? Means you are likely pinging the wrong address.. You don't have a DHCP server running?

Thanks,
Jaka

JoshTheKnightWhoSaysNICapogna

Yes, but I flashed via the usb bootloader, not the Ethernet. I'm pinging the camera default IP address of 169.254.1.222. Is this correct for my camera model?

I'm not using DHCP. I'm using the following IP on my PC

Can you run ipconfig and check the network interfaces? Perhaps the ping wants to go through the wrong one.

It's strange why it wouldn't work otherwise.
Do the lights flash on the POE injector/switch indicating that communication/power is going through?

Thanks,
Jaka

JoshTheKnightWhoSaysNICapogna

That was the hint I needed! Power was to the camera and lights on but not the communication light. Turns out Luxonis shipped me a bad cable. I swapped out to another industrial ethernet cable and it stared working. Luxonis is going to have to put some pressure on the cable supplier to test cables more frequently before ship. It was lucky I have a few M12 - Rj45 cat 6 cables around.

Until the next support request 🙂

Thank you
