Chapter 1

Introducing the PCI-DIO24/S

Overview: PCI-DIO24/S features

This manual explains how to install, configure and use the PCI-DIO24/S digital I/O board. You can use this board in a variety of digital applications to control logic devices such as switches, gauges, relays, pumps, and sensors.

The PCI-DIO24/S is a 24-bit, TTL-compatible digital I/O board. Digital I/O lines are accessed through a 37-pin connector. Digital I/O and interrupt pins are protected from electrostatic discharges of up to ±15 kV (air) and ±8 kV (contact).

An on-board, industry standard 82C55 programmable peripheral interface chip provides the 24 discrete digital I/O lines in three eight-bit ports (Port A, Port B, and Port C) for each board. 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. The PCI-DIO24/S supports 5V or 3.3V TTL/CMOS I/O signaling.

The PCI-DIO24/S has open locations where you can install a pull-up or pull-down resistor for each port. All I/O bits are set to input mode on power up and reset.

The PCI-DIO24/S board is completely plug-and-play, with no jumpers or switches to set. All board addresses are set by your system's plug-and-play software.

Software features

For information on the features of InstaCal and the other software included with your PCI-DIO24/S, 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 http://www.mccdaq.com/download.htm for the latest software version or versions of the software supported under less commonly used operating systems.

Installing the PCI-DIO24/S

What comes with your PCI-DIO24/S shipment?

As you unpack your board, make sure each of the items shown below is included.

Hardware

 PCI-DIO24/S

Chapter 2

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 PCI-DIO24/S and information regarding installation of that software. Please read this booklet completely before installing any software or hardware.

Optional components

If you ordered any of the following products with your board, they should be included with your shipment.  Cables

PCI-DIO24/S User's Guide Installing the PCI-DIO24/S

 Signal termination and conditioning accessories

MCC provides signal termination and conditioning boards that you can use with the PCI-DIO24/S. Refer to the "Field wiring, signal termination and conditioning" section on page 11 for a complete list of compatible accessory products.

Unpacking the hardware

As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the PCI-DIO24/S from its packaging, ground yourself using a wrist strap or by simply 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 by phone, 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

Installing the software

Install the software included with your board before you install the hardware. Installing the software first ensures 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-Software-

Quick-Start.pdf.

Installing the hardware

The PCI-DIO24/S is completely plug-and-play, with no switches or jumpers to set. Configuration is controlled by your system's plug-and-play software. 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 installing the 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 pops up as the system loads indicating that new hardware has been detected. If the information file for this board is not already loaded onto your PC, you will be prompted for the disk containing this file. The MCC DAQ software contains this file. If required, insert the Measurement Computing Data Acquisition Software CD and click OK.

3. To test your installation and configure your board, run the InstaCal utility you installed in the previous

section. Refer to the Quick Start Guide that came with your board for information on how to initially set up and load InstaCal.

Functional Details

The PCI-DIO24/S board features the following:  82C55 digital I/O chip interfaced to the PCI bus. The I/O pins of an 82C55 are bi-directional CMOS TTL

level.

 24-bits of digital I/O  37-pin I/O connector  Digital I/O and interrupt pins are protected from electrostatic discharges of up to ±15 kV (air) and

±8 kV (contact).

The 82C55 provides the 24-bit digital I/O channels into three eight-bit ports labeled Port A, Port B and Port C. Port C is further divided into two four-bit ports. You can program each port for input or output.

PCI-DIO24/S functions are illustrated in the block diagram shown here.

For more information on digital signal connections

For general information about digital signal connections and digital I/O techniques, refer to the Guide to Signal Connections (available on our web site at www.mccdaq.com/signals/signals.pdf).

Caution! Do not connect high current/voltage devices directly to the PCI-DIO24/S or you may damage the

resistor locations

Signal level control

All I/O bits are set to a high impedance input mode on power up and reset. To prevent unwanted signal levels, and to drive all outputs on the device you are controlling to a known state after power up or reset, install pull-up or pull-down resistors.

A pull-up resistor pulls all digital pins up to +5 V (high logic level). A pull-down resistor pulls all digital pins down to 0 V (low logic level).

Each board has open locations where you can install a 2.2 K , eight-resistor single inline package (SIP) resistor network for each port. 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. 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 (see Figure 5).

Figure 5. Eight-Resistor SIP Schematic

Each port provides 10 holes. Install an SIP on the board at the locations labeled Port A, Port B and Port C (see Figure 6).

Figure 6. Pull-up/down resistor locations

The end labeled HI connects to +5 V. The end labeled LO connects to GND. The eight holes in the middle (n0 – n7) connect to the eight lines of the port (Port A, B, or C). Figure 7 shows an SIP resistor network installed in both pull-up and pull-down positions.

To pull up the digital lines for a particular port, install the resistor with the common pin at the HI end. To pull down the digital lines for a particular port, install the resistor with the common pin at the LO end. When installed, the SIP resistors establish either a high or low logic level for each port when the board is in input mode.

Install MCC SIP packs

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).
