The SierraView 1080p MultiViewer controller card for SMP/MP-xx units. The MPX-MVC-3G MultiViewer controller card is used when you don’t need to exceed an output resolution of 1080p/60Hz or 3G. There is a choice of 2 MultiViewer output rears to accompany this card. Both of these provide 2 independent outputs and a RJ-45 port for control of the MultiViewer such as RMP-MVC-3G and RMP-MVC-DVI-3G.
