My ADI-TOF can't work in the far mode

Thanks so much for paying attention to my question!

I bought some ADI-TOF boards lately, it worked well. But recently when I reused it, the near mode and medium mode can work. But when I switched to far mode, something strangely happened, there is some error showed in exe:" Failed to get frame from device". And the exe was broke down and I couldn't use far mode to do tset.

I don't how to solve this problem, can you give me some guides?

Thanks again for your time!
