Safe upgrade. If power off or system break down occur when the firmware is being upgraded, it will automatically restore to the initial version. This function is only available for firmware version 1.21 and above.
LED Indicator
Status LEDs indicate the working state of each channel:
Pulsing slowly: idle
On: input signal locked
Off: input signal unlocked
Double blinks: memory failed or FPGA configuration failed
