The PB11MPCore provides four serial transceivers on the rear panel of the enclosure.

Figure A.7 shows the pin numbering for the 9-pin D-type male connector used on the PB11MPCore and Table A.4 shows the signal assignment for the connectors.

The pinout shown in Figure A.7 is configured as a Data Communications Equipment (DCE) device.
