Downframing—To expand the matrix video outputs beyond 32, you can loop the video from the first CM9770-MXB to subsequent CM9770-MXB units for an additional 32 monitor outputs on each matrix bay. Refer to Figure Figure 15..

You can connect a maximum of eight bays in a downframing configuration for a total MXB capacity of 256 monitors; in addition, you can increase monitor capacity further by using MDA units, for a total single-node system capacity of 512 monitors.

Refer to the Installing Additional Matrix Bays—Sideframing and Downframing section in the Appendix for detailed downframing instruc- tions.
