Rule R616

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 8‑12, and must be the only load connected to those terminals or

Figure 8‑11 Radio power source from a VRM

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 “RIO” Ethernet port on the wireless bridge (or the 18-24v PoE port for events using OM5P radios), or

C. directly from the PDP/PDP2.0/PDH ports described in R617 (this option is not permitted for OM5P radios)

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 or direct PDP/PDP2.0/PDH power into an Ethernet cable plugged into the radio port labeled “RIO.”

The use of a VRM or RPM to power the VH-109 radio is permitted in 2025 to allow transition to the new radio. In 2026 the radio will be required to be wired directly to the PDP/PDP2.0/PDH.
