fi

Cables, Connectors
Flat Ribbon Cables
All
fl
at ribbon cables with connectors are keyed, and therefore cannot be reversed. Most
fl
at
ribbon cables have locking cable clips. Be sure to reapply the clips when connecting cables.
Some
fl
at ribbon cables have exposed wires that insert directly into a wire trap connector. When
disconnecting and connecting these cables, you must look for the marking on the edge of the
cable denoting Pin 1 and be sure that you match it correctly with Pin 1 on the board.
Cable Routing
In some cases, tape secures cable connections or fastens cables to the bottom enclosure. Always
peel back the tape from one side when disconnecting cables so that the tape remains properly
positioned.
