Page 5: Chapter 1: Introduction
Chapter 1: Introduction The PCIe-DIO-48(S) is a x1 lane PCI Express (PCIe) board designed for use in a variety of Digital I/O (DIO) applications. It uses the high speed PCIe bus to transfer digital data to and from the board. The DIO emulates 8255 compatible chips making it easy program. -
Page 6: Figure 1-1: Block Diagram
When a port has COS enabled, any changes of the port's bits (low-to-high or high-to-low) will cause an interrupt. Refer to Chapter 5: Programming for enabling, disabling, and clearing the interrupts. Each DIO line is buffered and capable of sourcing 32mA or sinking 64mA. The VCCIO level is 5V or can be factory configured as 3.3V. -

Chapter 3: Hardware Details Option Selection Refer to the setup program on the CD provided with the board. Also, refer to the Block Diagram and the Option Selection Map when reading this section of the manual. C3 IRQ Enable To enable the C3 IRQ, install the IEN jumper in the "EN" position followed by a read/write access to Base Address + B (Refer to Chapter 5: Programming for details). -
Page 10: Vccio Resettable Fused Outputs
VCCIO Resettable Fused Outputs There are two 0.5A resettable fuses. Each fuse feeds one I/O connector at pin 49 used to power external module racks, relay boards, or for general purposes. If an over-current persists on a circuit protected by the resettable fuse, it will open interrupting power to the circuit. The amount of time it takes the fuse to act depends on the amount of over-current and other conditions such as ambient temperature, humidity, etc. -
Page 11: Chapter 4: Address Selection
The Device ID for the PCIe-DIO-48S is 0x0E61. The Device ID for the PCIe-DIO-48 is 0x0C61. The Device ID for the PCIe-DIO-24S is 0x0E53. This card uses I/O addresses offset from the base address assigned by the PCIe bus. The address spaces are defined in the programming section of this manual. -
