The PCIe-DIO Series digital boards

Overview about The PCIe-DIO Series digital boards

The PCIe-DIO Series digital boards are compatible with the PCI Express bus. Features include 24 or 96 DIO, selectable logic, high current output, and 82C55 mode 0 emulation. These devices provide easy migration from select PCI and ISA-based digital boards.

Digital Boards – The PCIe-DIO series includes the following products:

• PCIe-DIO24
• PCIe-DIO96H

Key features:

• The PCIe-DIO24 provides 24 lines of digital I/O with selectable 3.3 V and 5 V logic levels. The 24 DIO lines are organized into three groups of 8-bits each (Port A, Port B, and Port C). Port C can be further divided into two four-bit ports (Port C-HI and Port C-LO). The direction of each port is independently configurable with software for either input or output. Digital outputs are HC logic and can source and sink 2.5 mA.
• The PCIe-DIO24 has a 10 k resistor network associated with each digital port. You can configure each port for pull-up or pull-down with software. On power up and reset the configuration of each port is read from EEPROM. The board is shipped with each port configured in the pull-up state.
• 82C55 support for mode 0 only
• The PCIe-DIO24 emulates the 82C55 Programmable Peripheral Interface (PPI) chip. The PCIe-DIO24 hardware, Universal Library software, and Windows driver support mode 0 only.
• Digital I/O lines are accessible through a 37-pin D-type connector. The board has two individual slow blow fuses rated at 0.375 amp to protect the +VDIO and +12V outputs on the connector. One spare fuse is provided.
• Software programs written with the Universal Library for the USB-DIO24/37, PCI-DIO24 and CIO-DIO24 devices are fully compatible with the PCIe-DIO24.
• Power is provided by the PCI Express slot. The PCIe-DIO24 board is completely plug-and-play. All board addresses are set by the board’s plug-and-play software. Board configuration is controlled by the system BIOS.

Key features of PCI-DIO96H:

• The PCIe-DIO96H is fully compatible with software written for the PCI-DIO96H and USB-DIO96H.
• The PCIe-DIO96H provides 96 digital I/O lines in four independent port groups. Each digital port group is divided into two 8-bit ports and two 4-bit ports. The PCIe-DIO96H emulates an 82C55 chip in Mode zero. . You can configure each port independently for either input or output.
• The PCIe-DIO96H outputs are high-drive TTL that can source 15 mA and sink 64 mA. Additional buffering is typically not required to drive external devices. The board has two individual slow blow fuses rated at 1 amp that provide protection for the +5 V User Outputs. A spare fuse is provided.
• Each digital port has an associated 10 k resistor network. The board is shipped with each port configured in the pull-up state. You can change the port configuration with software. On power up and reset the configuration of each port is read from EEPROM.
• Digital I/O lines are accessed through a 100-pin high-density connector.
• The PCIe-DIO96H board is completely plug-and-play, with no jumpers or switches to set. All board addresses are set by the board’s plug-and-play software. Board configuration is controlled by your system’s BIOS.
• Power is provided by the computer’s internal 5 V Molex connector.
