Chapter 1 Introducing the PCI-DIO24 This manual explains how to install, configure and use the PCI-DIO24 digital I/O board. The PCI-DIO24 provides 24 lines of digital I/O. An on-board, industry standard 82C55 programmable peripheral interface chip provides the 24 digital I/O lines in three eight-bit ports (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). You can configure each port independently for either input or output. All

Chapter 4 Functional Details DIO signals All digital outputs and inputs on the PCI-DIO24 are CMOS TTL. Voltages and currents associated with external devices are usually far greater than can be supplied from a PCI-DIO24. Caution! Direct connections to high-current/high voltage devices will damage the board. The 82C55 digital I/O chip initializes all ports as inputs on power-up and reset. The state of the digital I/O lines is not defined as either logic high or logic low when in input m
