Signal diodes
Locations of the signal diodes for the primary Nexus Station components are shown in the next illustration.
Use this illustration to locate the diodes that will help you determine whether a communications signal is
traveling between the circuit board and the affected component. The diodes work in pairs, usually to indi-
cate position and/or movement of the component, such as open/closed, up/down, left/right, locked/
unlocked, clockwise/counter-clockwise. The individual component sections provide more detail
