LED indicators
D301 (L-8): BOOT
Indicates boot program startup status.
OFF: Startup by the normal boot program
ON: Startup by the backup boot program
D302 (L-8): CPU
Indicates CPU operating status.
Blinks at intervals of approx. 0.5 ms when the CPU enters the standby state.
D303 (L-8): APL
System operation check LED
This LED is for factory use.
D304 (K-8): INIT
This LED on the MIX-54 board indicates the INIT status of all FPGAs.
Lights when all FPGAs have started normally.
D305 (K-8): DONE0
Indicates the configuration status of the CPU control FPGA (IC5004).
Lights when configuration of the CPU control FPGA (IC5004) has been successfully completed.
D3301 (K-8): DONE1
Indicates the configuration status of FPGAs other than the CPU control FPGA (IC5004).
Lights when the configuration of FPGAs (IC5001, IC5002, IC5003, IC5005) other than the CPU control FPGA
(IC5004) has been successfully completed.
D1500 to D1507 (E, F-6): Image processing device status LEDs
Indicate the image processing device (IC6) status.
