Generation 2/EBRC Compatibility

The Enhanced Base Radio Controller (EBRC) serves as the main controller for the

Base Radio. The EBRC provides signal processing and operational control for

other Base Radio modules. Figure 1 shows a top view of the EBRC module with

the cover removed. The EBRC module consists of two printed circuit boards

(EBRC board and LED display board), a slide-in housing, and associated

hardware.

multiple receiver module assemblies.

❐ The EBRC module is not compatible with Legacy Base Radios that support
