1.2 PCVisionplus SPECIFICATIONS
•
The PCVisionplus video connectors are pin-compatible with the previous PCVision PCI-bus frame grabber and
camera cables. New cables support new camera features.
•
A hardware jumper selects the power-up state of the OPTO-22 compatible I/O port. All parallel port outputs have
an initial setting of either all 0 or all 1 based on the jumper setting. This feature adds flexibility when interfacing
with LEDs and module racks. Refer to Figure 1–4.
•
All addresses are assigned by the PCI-bus host computer. All configurable hardware characteristics are software
controlled.
