Rotary Switch
The 2P2 PMC/XMC Carrier Board provides a 16-position Rotary Switch that is connected

to change the switch position from the PMC Carrier Board front panel. The 16 positions
correspond to 16 user-defined meanings. Depending on the solder bead settings, the
rotary switch position may also be presented as a binary value on VME P2 connector
pins A2 through A5. Refer to
Table 2-13
on page 2-30 for details.
