ACU7517 firmware needed
 

hello all , i posted this question 2 days ago but i guess i misposted or something ,
i wonder if any one can help with a working firmware for
ACU7517-S75
the original version is
9.1.52
i've looked around alot , but it seems like this ACU7517 is new or just not widely used as i didnt find anything about it
any help would be much appreciated
thanks all
