Chapter 1

Introducing the PCI-INT32

The PCI-INT32 is intended to be used in conjunction with the ZILOG Z8036/Z8536 Product Specification. This
document is available on our web site at www.mccdaq.com/PDFmanuals/Z8536.pdf

The PCI-INT32 can accept up to 32 vector interrupts and output an interrupt to the PC. The board has a pair of
Z8536 I/O chips interfaced to the PCI bus. Each Z8536 accepts up to 16 independent inputs that can be used to
generate interrupts from bit patterns or individual bit states or transitions. The interrupt outputs from two X8536
chips can be ANDed using software.

Many other functions can be performed by the PCI-INT32 including digital pattern recognition, counting with
six 16-bit counters, and up to 40 bits of digital I/O.

The 16-bit counters can be set up independently or chained together in groups of three.

The I/O pins of the Z8536 are TTL levels. All I/O lines are accessible through a 50-pin header connector.
Connections to the board typically use the C50FF-# cable and the CIO-MINI50 terminal board.

Unpacking the PCI-INT32

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-INT32 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:

Installing the software

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 PCI-INT32

The PCI-INT32 board is completely plug-and-play, with no switches or jumpers to set. 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 installing
the software.

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

1.

Close your computer and turn it on.

2.

A dialog box pops up as the system loads indicating that new hardware has been detected. If the

ormation file for this board is not already loaded onto your PC, you will be prompted for the disk

inf

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 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

PCI-INT32 block diagram

PCI-DIO96 functions are illustrated in the block diagram shown here.

Chapter 4

Figure 4-1. PCI-INT32 functional block diagram

DIO signals

All digital outputs and inputs on the PCI-INT32 connector are TTL (Transistor-Transistor-Logic). TTL is an
electronics industry term which describes a standard for digital signals which are either at 0 V or 5 V (nominal).

Under normal operating conditions, the voltages on the Z8536 pins range from near 0 volts for the low state to
near 5.0 volts for the high state. The current handling capability of these inputs / outputs is limited to a few
milliamps. This is typical of TTL devices.

4-1

PCI-INT32 User's Guide Functional Details

Caution! The voltages and currents associated with external devices range from less than a hundred mA at a

few volts for a small flash light bulb to 50 Amps at 220 volts for a large electric range. Attempting
to connect either of these devices directly to the PCI-INT32 would destroy the I/O chip.

For general information regarding digital I/O techniques, including signal conditioning and low pass filters,
refer to the Guide to Signal Connections. This document is available on our web site at

www.mccdaq.com/signals/signals.pdf

).

IMPORTANT

The Z8536 digital I/O chip 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 Z8536 it will probably be turned ON every
time the Z8536 is reset, or, it might be turned OFF instead. Remember, and Z8536 which is reset is in INPUT
mode.

It cannot be stated often enough to those unfamiliar with the Z8536 — whenever the Z8536 is powered on or
reset, all pins are set to high impedance input.

Output devices such as solid state relays may be switched on whenever the computer is powered-on or reset. To
prevent unwanted switching and to drive all outputs to a known state after power-on or reset, pull pins either
high or low with a pull-up or pull-down resistor.

Pull-up/down resistors

When the Z8536 digital I/O chip is powered-on or reset, the control register is set to a known state. When used
as an output device to control other TTL input devices, the Z8536 applies a voltage level of 0 V for low and

2.5 V to 5 V for high. The device being controlled responds to the output voltage level of the Z8536 chip.

The concept of voltage level of a Z8536 chip in input mode is meaningless. Do not connect a volt meter to the
floating input of a Z8536. It will show you nothing of meaning. In input mode, the Z8536 is in 'high Z' or high
impedance. If your Z8536 was connected to another input chip (the device you are controlling), the inputs of
that chip are left floating whenever the Z8536 is in the input mode. If the inputs of the device you are
controlling are allowed to float, they may float up or down. The direction they float is dependent on the
characteristics of the circuit and is unpredictable. This is why it often appears that the Z8536 has gone 'high'
after power up. The result is that the controlled device gets turned on. That is why you need pull up/down
resistors. shows a Z8536 digital output with a pull-up resistor attached. Figure 4-2

Controlled Device

Figure 4-2. Z8536 digital output with pull-up resistor

The pull-up resistor provides a reference to +5V, while its value of 2,200 Ω allows only a little current to flow
through the circuit.

If the Z8536 is reset and enters high impedance input, the line is pulled high. At that point, both the Z8536
AND the device being controlled will sense a high signal. If the Z8536 is in output mode, the Z8536 has more
than enough power to override the pull-up resistor's high signal and drive the line to 0 volts (nominal).

4-2

PCI-INT32 User's Guide Functional Details

With a pull-down resistor installed, the line is pulled low when the Z8536 is reset. The Z8536 has more than
enough power to drive the line high.

To safeguard against unwanted signal levels, all devices that are controlled by the Z8536 chip should be tied
low or high as required by a 2.2K Ω resistor. Open positions are located on the board to install resistor Single
Inline Packages (SIP). The positions are marked A, B, and C and are adjacent to the Z8536.

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 (refer to ). Figure 4-3

Digital I/O Lines

When installed, the SIP establishes either a high or low logic level at each of the eight I/O lines on the port. At
each board location, A, B, and C, there are 10 holes in a line. The hole on one end is marked "HI" and is
connected to +5V. The other end is marked "LO" and is connected to GND. The eight holes in the middle
connect to eight lines of the port, A, B or C.

To pull-up lines, orient the SIP with the common pin (dot) toward the HI end; to pull-down, install the resistor
with the common pin in the LO hole.

Note:

We recommend using 2.2K SIPs (MCC part number SP-K2.29C). Use a different value only if necessary.
