I recently got three Adaptive Alpha 4160 walldisplays that I would like to use to promote my band.
I need free software to operate the displays.
For the Alpha 4160R LED Display: http://alpha-american.com/p-alpha-4160r.html#software
For the Alpha 4160C LED Display: http://alpha-american.com/p-alpha-4160c.html#software
AlphaNet is most likely what you need: http://alpha-american.com/p-alphanet.html
It doesn't look like it's free though. I thought I found an open source alternative but can't seem to find the link anymore
