Appendix B: Connector Pinouts
Pin-outs for all I/O connectors on the QScreen are provided here.
The QScreen Controller combines an embedded computer based on the 68HC11 microcontroller with a touch panel and LCD (liquid crystal display) graphic user interface (GUI) that is ideal for instrument control and automation.
QScreen Connectors
The pinouts of all of the connectors on the QCard Board are presented below. To locate the connectors on the board, consult Figure B–1 and the white silk–screened labels on the visible side of the QCard Board. The arrows in the figure point to the locations of pin 1 on each connector.
