The PVI-800 is one of the two navigation systems of the KA-50.  It has no graphical display.  It operates independently of the ABRIS, the only exception being the graphic representation of a navigation target of the PVI-800 in the ABRIS as a blue square.  The PVI-800 is based on the INU of the KA-50.  The PVI-800 delivers the data to the route autopilot of the KA-50.
