So, this is a weird one. I have a pair of robots (KRC4, KSS 8.3) with KUKA VisionTech 3.0, and using the KUKA MXG20 smart cameras.
I've run into an issue connecting the cameras to the robots. These robots were configured with VisionTech from the factory, and came pre-installed with the Power-Over-Ethernet option for the cameras. And when these robots were at the integrator's facility, the cameras worked -- I was able to get live video from the cameras to the SmartPads. I never looked closely at the cables, since they were all installed before I arrived on-site.
Since then, the system was broken down and moved to the final customer location. In the process, the original robot-to-camera cables were replaced with new cables (both KUKA-sourced), due to routing issues requiring longer cable runs. And now, I can't get a connection -- there's not even a power light on the cameras.
When I examined the new cables closely, I found that the cables have male M12 ends. And when I check the VisionTech 3.0 manual, I see that the PoE/Data port on the camera is also male. This obviously can't work. And to make things worse, aside from being male/female, the "aux power and I/O" port on the camera is physically identical to the PoE cable. So, obviously, the new cables are wrong. Right?
Except... I had someone (over the phone) check the original cables, and those cables also have male M12 ends.
So, the only thing I can think of is that the manual is wrong? I've attached the relevant images from the manual. It's obvious that I can't run images over the power supply port, so either something really strange is going on, or the manual is incorrect on which port is which in the first image.
Anyone ever run into this before? I'm having the original cables shipped to me post-hast, but in the meantime, I'm stuck.
