I was planning on a URC MX 880, with wireless. I have had good results in the past with this system.

I looked at the discreet codes for Samsung devices and found 37 TV models but nothing for this series of TV.

I have not put in any control system yet for a "smart" UHD Samsung, the interface box is new to me. I have read it will not respond to rs232, but I supposedly have a new list coming from Samsung support anyway, just to experiment with.
