1.5.1. Target Diagnostics

The BDx Module incorporates Target Diagnostics, a six-LED matrix on the rear panel that mirrors the status indicators located on each major internal assembly. The Target Diagnostic LEDs are readable with the unit rack-mounted and with the covers attached. Target Diagnostic LEDs correspond to the internal assemblies listed in LED Map for Target Diagnostics. Each LED flashes the Morse Code dot/dash pattern shown in LED Morse Code patterns and descriptions to report the assembly’s state (heartbeat, configuration notice, or fault).
