12.1 Physical Description

The Backplane distributes signals between the Main Board, I/O Driver Board, and all
peripheral sub-systems.
The MAV/6 Backplane is a printed circuit board assembly (PCBA) mounted
vertically at the rear of the cabinet, partly behind the logic cage (see Figure 12-1).
The Backplane mounts onto standoffs which are studded onto the back wall of the
logic cage.
The Backplane is fitted with two types of connectors: Minifit Junior and DIN. The
Main Board and I/O Driver Board are inserted directly onto the Backplane.
Peripheral subsystems are connected to the Backplane via ribbon cables or wire
looms. The layout of the connectors on the Backplane is shown in Figure 12-2.
