Chapter 1 Introducing the PCI-DIO48H Overview: PCI-DIO48H features This manual explains how to install and use the PCI-DIO48H board. The PCI-DIO48H is a logic-level digital I/O board designed for the PCI-bus. The PCI-DIO48H provides 48-bits of digital I/O. The I/O is organized into two 24-bit groups based on an 82C55 mode 0 emulation. Each 24-bit group is divided into three eight-bit ports — PORT A, B, and C. PORT C can be split into two four-bit nibbles — C-HI and C-LO.

Chapter 2 Installing the PCI-DIO48H What comes with your PCI-DIO48H shipment? The following items are shipped with the PCI-DIO48H. Hardware PCI-DIO48H board Additional documentation In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf). This booklet supplies a brief description of the software you received with your MCC Hardware and information regarding installation of that software.
PCI-DIO48H User's Guide Installing the PCI-DIO48H Signal termination and conditioning accessories MCC provides signal termination products for use with the PCI-DIO48H. Refer to Field wiring, signal termination and conditioning on page 12 for a complete list of compatible accessory products. Unpacking the board As with any electronic device, you should take care while handling to avoid damage from static electricity.

Chapter 3 Functional Details CIO-ERB24 and SSR-RACK24 daisy chain configuration Many relay and solid-state relay (SSR) racks provide only 24-bits of digital I/O. You can configure the CIOERB24 relay output board and SSR-RACK24 I/O module rack in a daisy chain configuration to use all of the digital I/O bits provided by the PCI-DIO48H board. An example of the daisy chain configuration scheme for each board is shown below. The PCI-DIO48H provides digital I/O in a group of 48 bits.
PCI-DIO48H User's Guide Functional Details Pull-up and pull-down resistors The PCI-DIO48H has open locations where you can install a 2.2 K , eight-resistor single inline package (SIP) resistor network for each port. The locations are labeled PORT 1A, PORT 1B , PORT 1C (RN10 to RN12), and PORT 2A, PORT 2B, and PORT 2C (RN13 to RN15). The SIP is made up of eight 2.2 K resistors. One side of each resistor is connected to a single common point and brought out to a pin.
