2.3.4 PCB INTERCONNECTIONS
Signal interconnection between the input boards and the display board is via ribbon cables.
The power supplies to the display board come from each input board via a 6-core cable.
Slots are provided in the base plate to guide the cables towards the hinge-side of the
enclosure case, thus minimising any cable strain when the enclosure lid is opened. See
Figure 2.1 for layout details.
