APPENDIX A
VIDEO CONNECTIONS
CONNECTORS
The PCVisionplus provides three connections to the outside world. On the I/O plate there are two D-Sub connectors
(15 and 26-pin) for camera and miscellaneous interface connections. Each D-Sub connector supports one camera.
Internal to the PC, at the top edge of the PCB, is a 50-pin dual row post header connector. This provides parallel I/O
capability in the form of 8 input and 8 output, high-drive TTL channels.
A jumper labeled “I/O Level” on the PCVisionplus board sets the power-up state of the parallel port outputs. All
parallel port outputs have an initial setting of either all 0 or all 1 based on the jumper setting. Refer to Figure A–1.
