Changing a Matrix Size from 4x4 to 6x1

Other sizes are possible here is just one example, we are using a 60-750-144 which is a 4x4 RF Matrix with loop through.

 


You can turn the 60-750-144 into a 6x1 mux as follows:
Place a cable between x4 and y1 loopthru and use y1 as common (row connection) and x1,x2,x3,y2,y3,y4 as your 6 x connections.
Using the LXI Direct Driver issue following instructions to make each connection:

DWORD SubUnit;
SubUnit = 2;

PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 1, 1, 1) connect x1 to y1
PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 1, 2, 1) connect x2 to y1
PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 1, 3, 1) connect x3 to y1

PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 1, 5, 1) connect y1 loopthru to y1 (y1 is now connected to x4)

PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 2, 4, 1) connect y2 to x4
PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 3, 4, 1) connect y3 to x4
PIPLX_OpCrosspoint(Sid, Cardid, SubUnit, 4, 4, 1) //connect y4 to x4
