We have been having trouble running the limelight. We have it wired directly to the radio via an Ethernet cable and have tried using both limelight software and photonvision software. The problem is that whenever the limelight is powered on, either the robot controllers start to glitch, or some motor on the robot doesn’t seem to get enough power and fails to function properly. Is it possible that the issue is caused by an incorrect way the camera is wired, or something else?
That is odd and I haven’t seen it before.
You should have positive and negative wires going from the little white plugs on the LL directly to a red/black set on the PDP (or PDH) with a breaker.
More details on your setup’s power would be helpful.

On an unrelated note you should probably use a network switch as I assume you are using the second port on the radio which causes issues frequently.

Not sure if this is part of the issue that is going on here but just like @Technologyman00 said its not recommended to use the second port on the radio, highly suggested to have a quick read of this post. Why you probably shouldn't use the second port on your OpenMesh OM5P Radio and embrace using an Ethernet Switch instead

or poor wiring technique such as a wire “hair” barely touching something it shouldn’t. You might be using POE to the LL and didn’t put that together right. We helpers need an as-built wiring diagram and you should first compare that with what you intended; you might answer your own question. You need to inspect connections with a magnifying glass and do a gentle tug-test since the perfect wiring diagram doesn’t mean perfect execution. Do you hear circuit breakers clicking?
Also, exactly what do you mean by robot controllers?
never before used by me CD feature
I was typing this response last night when the Comcast Internet connection failed. Signed on to CD this morning and my typing is here exactly as I left off last night - nice feature!

I highly recommend Ferrules for solving this

I think the root of your problem is that it’s wired directly to the radio. Normally you should have a separate switch, especially if you are running multiple cameras at once. Using the second ethernet port can be kinda finniky and it’s just good practice to use a switch anyways. If the issue still persists, try getting a different Ethernet cable. You might be using the wrong cable type or one of the twisted pairs could be compromised.
Another potential issue could be how you have laid out your cables. Let’s pretend the issue isn’t with the radio (even though it most likely is). A few things with how you have your cable running can cause issues with data transmission. The most common issue is bending your cable to sharply. If you are using a Cat 5, 5e, or 6 cable, the minimum bend radius is about an inch (4 times the diameter of the cable). If you bend your cable past this point, you risk transmission errors from cross-talk (pulses from 2 cables interfering due to proximity) or damaging the wires inside. Also, having exposed wires causes issues. Not only is it a safety hazard, but if you have multiple exposed cables next to each other it can cause more cross-talk.
Just check your cables for any tears, creases, or other types of damage; and try to not force them into places they don’t want to go. It shouldn’t be at all difficult to move or plug in cables.
I shine a bright light on the area where the wires go into the connectors and look for anything shiny. Move the light so it shines on that area from different directions.
+1 on the tug test. That is standard operating procedure in manufacturing plants doing their own wiring.
