This won’t work assuming you want to use all three ports at once. You want a “network switch” or “ethernet switch” which will allow you to use all of the ports at once. I’ll second the recommendation for the Brainboxes switches, specifically SW-005 or SW-008.
Use an ethernet switch.
There are many known issues with using the two ports on the radio (long story short, there’s a silicon-level bug that causes the coupling of the two ethernet ports to be unreliable). Many teams have had success with the Brainboxes SW-005 switch - it can be powered off one of the low-current channels on your PDH, and is easily mountable. You can use your team’s Digi-Key voucher from the virtual Kit of Parts on it.
Yes, if it’s powered by 12 or 18 volt “passive” PoE or with a 12 or 5 volt barrel jack. It should say on the label what it takes. It also can’t output “standard” or “active” PoE because that’s too high a voltage. R203.i limits all circuitry used on the robot to a maximum 24 volts, and standard PoE is about 44 volts.
R616 *Power radio as specified – Part 1. The wireless bridge (radio) power must be supplied by either:
A. the 12V 2A output of a CTR Electronics Voltage Regulator Module (VRM) (P/N am-2857, 217-4245), as shown in Figure 9-13, and must be the only load connected to those terminals…
Ok so I have the network switch wired up to the radio, roborio, and limelight but I still can’t connect to photonvision.local. I have verified that I have comms and can drive but the limelight still isn’t connecting. All the webpage says is that it refused to connect.
