5. The 50-pin I/O connector on your MIO board may have small plastic key inserts installed for
mating with military polarized connectors. Because these keys are incompatible with the
50-pin connector on the SH6850 shielded cable, you must remove them. The 50-pin SH6850
connector has a center polarization bump that prevents you from inserting the connector
upside down.
To remove the key inserts, use a thin probe such as a pencil or a pen tip to gently press down
on the release tab in the center of the key insert (see Figure 4). Then use the probe to lift up
the back end of the key insert and slide the insert off the connector.
