Software and connector compatibility with PCI-DIO24 and CIO-DIO24 for seamless migration of existing applications
General Description
The PCIe-DIO24 is a 24-channel digital I/O board with selectable 3.3 V or 5 V logic levels for PCI Express bus compatible computers. The 24 bits function as an 8-bit Port A, an 8-bit Port B, and an 8-bit Port C, which may be further divided into two 4-bit ports (Port C-HI and Port C-LO).
There is a 10 kilohm pull-up/pull-down resistor network associated with each digital port. Their direction is software selectable and stored on the board, so the user can use the board in a different PC without running configuration software: simply set the board number in InstaCal.
The PCIe-DIO24 is connector and software compatible with Measurement Computing's highly popular PCI-based PCI-DIO24 and ISA-based CIO-DIO24 boards, making migration from the ISA or PCI bus about as simple as unplugging the digital I/O cable?s 37-pin connector from the old board and plugging it into the new one. The PCIe-DIO24 is also supported by the same wide variety of external relay and solid state I/O module racks.
The PCIe-DIO24 is completely plug-and-play. There are no switches, or jumpers on the board. All board addresses, interrupt channels, etc. are set by your computer's plug-and-play software.
