Firmware RDC6442S-B (ec)

[Fuflun]

I have a laser with this card," RDC6442S-B (ec)" it gives me some problems I wrote in another thread.

I would like to try to overwrite the firmware, but on the company website it is only for RDC6442G cards, is that okay? or it is specific for the "S" series
And if you need to know where to download it from? On the Ruida website, there isn't


Thanks to who will answer
