dans95tbird 0 Posted October 13, 2013 My question is that I currently have 2 brand new 16 channel Samsung DVR's that run on the RS-485 protocol. I also have 2 American dynamics keyboards model ad2088 and a new touch tracker. Is there any way to connect these keyboards to the Samsung DVR's. If so how would I go about doing this? Thanks Alot Share this post Link to post Share on other sites
