Alternatively up to 16 video sources can be attached with video extension board IS-SLOT-D26 in connection with two video connecting cables (the FALCONquattro/FALCONquattro Express cable Vin 1-8 (D26 to 8BNC) and FALCONquattro cable Vin 9-16 (D26 to 8BNC)) via BNC sockets on FALCONquattro/FALCONquattro Express.
Connection to FALCONquattro/FALCONquattro Express is made by 4 flat ribbon cables, whose 10-pin plugs (like plug J11) are attached to the plugs J1 to J4 of the FALCONquattro/FALCONquattro Express. In order to connect video sources via BNC sockets optional available video connecting cables can be attached to two 26-pin sockets J12 and J13. Following figure shows the video extension board with DSUB sockets and flat ribbon cables.
