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. Each of these ports may be individually programmed
as input or output.
All digital inputs are LSTTL. The output signals are buffered high output drive TTL. The digital output drivers
are 74ABT244 chips that can sink 64 mA and source 15 mA. The input buffers are 74LS373 chips and have thestandard high input impedance of the 74LS series devices.
Digital I/O lines are accessible through a 50-pin header connector. The board has a slow blow fuse rated at
1 amp that protects the +5 V User Output on the connector. One spare fuse is provided.
On power up and reset, all I/O bits are set to input mode. If you are using the board to control items that must be
OFF on reset, install pull-down resistors. Each board is equipped with open locations where you can install SIP
resistor networks for either pull-up or pull-down.
The PCI-DIO48H 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.

Software features
For information on the features of InstaCal and the other software included with your PCI-DIO48H, refer to the
Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.
Check www.mccdaq.com/download.htm for the latest software version or versions of the software supported
under less commonly used operating systems.

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. Before removing the PCI-DIO48H from its packaging, ground yourself using a wrist strap or bysimply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately byphone, fax, or e-mail:

Phone: 508-946-5100 and follow the instructions for reaching Tech Support.
Fax: 508-946-9500 to the attention of Tech Support
Email: techsupport@mccdaq.com

For international customers, contact your local distributor where you purchased the PCI-DIO48H. Click on thislink www.measurementcomputing.com/sales.asp to locate your distributor.

Installing the software
Install the software included with your board before you install the hardware. Installing the software firstensures that the information required for proper board detection is installed and available at boot up.
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-SoftwareQuick-Start.pdf.

Installing the hardware
The PCI-DIO48H board is completely plug-and-play. There are no switches or jumpers to set on the board.
Configuration is controlled by your system's BIOS. To install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installingthe software.
1.

Turn your computer off, open it up, and insert your board into an available PCI slot.

2.

Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or
Windows XP), a dialog box opens as the system loads, indicating that new hardware has been detected. The
information file for this board should have already been loaded onto your PC when you installed the
Measurement Computing Data Acquisition Software CD supplied with your board, and should be detected
automatically by Windows. If you have not installed this software, cancel the dialog and install it now.

3.

To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up andload InstaCal.

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 thedigital I/O bits provided by the PCI-DIO48H board. An example of the daisy chain configuration scheme foreach board is shown below.
The PCI-DIO48H provides digital I/O in a group of 48 bits. To use all of the board's 48 digital I/O bits tomonitor and control relays and/or SSRs, configure the daisy chain as shown in Figure 3.

The 24 digital I/O bits on pins 1-24 control the second relay board on the chain. The 24 digital I/O bits on
pins 25-50 control the first relay/SSR board on the daisy chain.

82C55 emulation (mode 0)
The PCI-DIO48H emulates the 82C55 chip (mode 0). The 82C55 emulation initializes all ports as inputs on
power-up and reset. A TTL input is a high impedance input. If you connect another TTL input device to the
output, it could be turned on or off every time the board is reset.
To establish a consistent TTL level at power-up, use resistors tied to either +5V (pull-up) or ground (pulldown). There are open locations for pull-up and pull-down resistor packs on the board.
Whenever an 82C55 emulation is powered on or reset, all pins are set to high-impedance input. Based onstandard TTL functionality, these inputs will typically float high, and may have enough drive current to turn on
external devices.
Consequently, if you have output devices such as solid state relays, they may be switched on whenever thecomputer is powered on or reset. To prevent unwanted switching, and to drive all outputs to a known state after
power on or reset, pull all pins either high or low through a 2.2 K resistor.

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 andbrought out to a pin. The common line is marked with a dot or line at one end of the SIP. The remaining resistor
ends are brought out to the other eight pins (refer to Figure 4).
2.2 KOhm SIP
Dot(LO or HI)

I/O Lines

Figure 4. Eight-resistor SIP schematic

The SIP may be installed as pull-up or pull-down. At each RN# location, there are 10 holes in a line. One end of
the line is +5V, the other end is GND. They are marked HI and LO respectively. The eight holes in the middle
are connected to the eight lines of a port.


For a pull-up function, mount the SIP with the common pin (marked with a dot or line) in the HI position.
For a pull-down function, mount the SIP with the common pin in the LO position.

When installing pull-up and pull-down resistor SIP packs, we recommend using a 2.2 K, eight-resistor SIP(MCC part number SP-K2.29C).
Unconnected inputs float
Unconnected inputs typically float high, but not reliably. If you are using a PCI-DIO48H for input and haveunconnected inputs, ignore the data from those lines. You do not have to terminate input lines. Unconnectedlines will not affect the performance of connected lines. Mask out any unconnected bits in software.

Replacing a fuse
The PCI-DIO48H has a 1 amp slow blow fuse connected to the +5V User Output at pin 49, and is labeled F1 on
the board. A spare fuse is installed on the board at location F2. Each fuse is secured to the board with clips forconvenient replacement.
A fuse will blow during operation if amperage exceeds 1 amp. If you need to replace a fuse, perform thefollowing procedure.
1.

Pry the center of the fuse from the fuse holder clip.

2.

Insert the replacement fuse into the fuse holder clip.
