PCIe-DIO24: PCI Express (PCIe) bus compatible, 24-channel digital I/O board The PCIe-DIO24 is a 24-channel digital I/O board with selectable 3.3V or 5V 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. 24 channels of digital I/O with selectable 3.3V and 5V logic levels: 8-bit Port A, 8-bit Port B, 8-bit Port C (may be made up of 4-bit C-HI, and 4-bit C-LO) Fully plug-and-play Emulates 82C55 mode zero Software selectable pull-up and pull-down resistor configurations Digital I/O lines are accessed through a 37-pin D-type connector Software and connector compatibility with PCI-DIO24 and CIO-DIO24 for seamless migration of existing applications

PCIe-DIO96H: PCI Express (PCIe) bus compatible, 96-channel, high output current digital I/O board Measurement Computing's PCIe-DIO96H is a high-density, 5-volt logic level, digital I/O board for PCI Express compatible computers. It offers 96 channels of digital I/O. It provides the I/O in four 24-bit groups based on an 82C55, mode 0 emulation. Each group provides an 8-bit port A, an 8-bit port B, and an 8-bit port C that can be split into a 4-bit port C-HI and a 4-bit port C-LO. The PCIe-DIO96H outputs are high-drive TTL that can source 15 mA and sink 64 mA. 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. 96-bidirectional I/O channels (5 V compatible), in four independent port groups Each digital port group is divided into two 8-bit ports and two 4-bit ports Fully plug-and-play Emulates 82C55 mode zero Software selectable pull-up and pull-down resistor configurations Digital I/O lines are accessed through a 100-pin connector Software and connector compatibility with PCI-DIO96H for seamless migration of existing applications
