A.2.4 Monitor Back Panel
The monitor back panel has several connectors for the cables that connect the
monitor to the cabinet (see Figures A-1, A-2, and A-3).

•The four 75 Ω terminators attached to the monitor by chains control the
impedance of the video signals. When a single monitor is used, the terminators
plug into the unused BNC sockets. When more than one monitor is used in a
daisy-chain, the terminators are removed from the sockets on all but the last
monitor.
