Overview of Prism Remote Units
SeRF Module LEDs
NOTE: The SeRF Module LEDs automatically enter a LED Roll Test sequence (cycle through its colors)
when the SeRF FPGA is loaded (approximately 4 minutes after initial power up) or when a
SeRF synthesizer failure occurs. The LED Roll Test sequence takes approximately two seconds
to complete, and cycles the ALARM, SYNTH, and STATUS LEDs, after which the LEDs begin
normal operation. Additionally, an active SeRF Synthesizer failure causes the same LED
sequencing approximately every minute until the SeRF failure clears.
