R616       *Power radio as specified – Part 1. The wireless bridge (radio) power must be connected based on the radio type:

A.      For VH-109 radios, radio power must be sourced from one or both of:

a.      Injected into the “RIO” port of the radio using a passive injector or modified Ethernet cable connected directly to a PD, and/or

b.      Wired directly to the 12V power input of the radio from a PD.

B.      For OM5P radios (China events only), radio power must be sourced from only one of:

a.      the 12V/2A output of a CTR Electronics Voltage Regulator Module (VRM) (P/N am-2857, 217-4245), as shown in Figure 8‑12, and must be the only load connected to any of the 12V/2A terminals or

Figure showing Radio Power source on VRM.

b.      using an Ethernet cable between a REV Radio Power Module (RPM) (P/N REV-11-1856) and the “18-24v PoE” port. 

Note that this prohibits using any other active PoE injector device to power the radio but does not prohibit using any PASSIVE CONDUCTORS to inject the VRM power into an Ethernet cable plugged into the OM5P radio port labeled “18-24v PoE.”

Please reference How to Wire an FRC Robot for wireless bridge wiring information.

R617       *Power radio as specified – Part 2. The device supplying power to the wireless bridge per R616 must be connected directly to a non-switched pair of protected output terminals of a PD with a 10A fuse or circuit breaker installed with the exception of the PDP 1.0 shared VRM/PCM pairs which may be protected with a 20A fuse or circuit breaker.
