Appendix A - QED Connector Pinouts
The pinouts of all of the connectors on the QED Board are presented below. To locate the connectors on the board, consult Figure A.1 and the white silkscreened labels on the "memory side" of the QED Board. On the "processor side" of the board, the legend indicates the location of pin 1 and the highest numbered pin on each connector.
Note that some signals have compound names to suggest multiple functions. For example, PPC4/RS485.XMIT on the digital I/O bus is a signal that can be configured as a general purpose digital I/O line named PPC4, or as a signal that controls the direction of data flow if the RS485 serial port is in use. Also note that pins labeled "N/C" are not connected to anything.
