The RS-232 connector is located on the back of the cradle. When the MX3 is properly docked, the
bi-directional half-duplex transceivers in the MX3 and cradle are aligned through their IR
windows. The half-duplex IR signals from the MX3 are converted to RS-232 signals in the cradle
and available at this connector.
