Chapter 1

Introducing the USB-DIO96H

Overview: USB-DIO96H features

This user's guide contains all of the information you need to connect the USB-DIO96H to your computer and to
the signals you want to measure or control.

®

The USB-DIO96H is supported under popular Microsoft
fully compatible with both USB 1.1 and USB 2.0 ports

The USB-DIO96H provides 96 digital I/O lines, high output current, and one 32-bit external event counter. The
USB-DIO96H is powered by an external +9 V unregulated power supply that is shipped with the board. A USB
cable is also included.

Power OUT and USB OUT connectors let you power and control multiple MCC USB Series products from one
external power source and one USB port in a daisy chain fashion. Depending on your load requirement, daisy
chained boards may require a separate power supply.

Windows® operating systems. The USB-DIO96H is

You can connect your field wiring directly to the board's screw terminals. The 96 digital I/O lines are available
in four independent port groups. Each digital port group is divided into two 8-bit ports and two 4-bit ports, and
is a discrete emulation of 82C55 mode zero operation. You can configure each port independently for either
input or output.

The USB-DIO96H outputs are high-drive TTL that can source 24 mA and sink 64 mA. Additional buffering is
typically not required to drive external devices.

Each digital port has an associated pull-up resistor to drive the ports high during power up and reset. You can
optionally configure this resistor for a pull-down configuration. All I/O bits are set to input mode on power up
and reset.

The USB-DIO96H also provides 50-pin mass termination connectors. For OEM's who wish to use the mass
term connectors, the enclosure needs to be removed.

The USB-DIO96H is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench (see
Figure 1-1).

USB-DIO96H User's Guide Introducing the USB-DIO96H

Connecting a USB-DIO96H to your computer is easy

Installing a data acquisition device has never been easier.

! The USB-DIO96H relies upon the Microsoft Human Interface Device (HID) class drivers. The HID class

drivers ship with every copy of Windows that is designed to work with USB ports. We use the Microsoft
HID because it is a standard, and its performance delivers full control and maximizes data transfer rates for
your USB-DIO96H. No third-party device driver is required.

! The USB-DIO96H is plug-and-play. There are no jumpers to position, dual in-line package (DIP) switches

to set, or interrupts to configure.

! You can connect the USB-DIO96H before or after you install the software, and without powering down

your computer first.

When you connect an HID to your system, your computer automatically detects it and configures the
necessary software. You can connect and power multiple HID peripherals to your system using a USB hub.

! You can connect your system to various devices using a standard four-wire cable. The USB connector

improves upon serial and parallel port connectors with one standardized plug-and-port combination.

! Data can flow two ways between a computer and peripheral over USB connections.

Make sure that you have the latest Windows Updates installed for your USB driver, particularly "XP Hotfix
KB822603."

USB-DIO96H User's Guide Installing the USB-DIO96H

If you are running Windows XP and connect the USB-DIO96H to a USB 1.1 port, a balloon displays the
message "

Your USB device can perform faster if you connect to a USB 2.0 port." You can ignore this

message. The USB-DIO96H will function properly when connected to a USB 1.1 port, although USB
bandwidth will be limited.

When installation is complete, the USB LED should flash and then remain lit. This indicates that
communication is established between the USB-DIO96H and your computer.

If the USB LED turns off

If the USB LED is lit but then turns off, the computer has lost communication with the USB-DIO96H. To
restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore
communication, and the USB LED should turn back on.

Caution! Do not disconnect any device from the USB bus while the computer is communicating with the

USB-DIO96H, or you may lose data and/or your ability to communicate with the USB-DIO96H.

If your system does not detect the USB-DIO96H

If a "

USB device not recognized" message appears when you connect the USB-DIO96H, do the following.

! Unplug the USB cable from the USB-DIO96H.
! Unplug the external power cord from the POWER IN connector on the enclosure.
! Plug the external power cord back into the POWER IN connector.
! Plug the USB cable back into the USB-DIO96H.

Your system should now properly detect the USB-DIO96H hardware. Contact technical support if your system
still does not detect the USB-DIO96H.

USB-DIO96H User's Guide Functional Details

Power terminals

The USB-DIO96H has three +5 V power output terminals. Each power output terminal is labeled 5V. A total of
50 mA may be drawn from the 3 terminals.

Caution! Each 5V power terminal is an output. Do not connect to an external power supply or you may

damage the USB-DIO96H and possibly the computer.

Ground terminals

The USB-DIO96H has four identical ground (GND) connections - one ground terminal per digital port group.
The ground terminals provide a common ground for all USB-DIO96H functions.

Counter terminal

Connect an external TTL signal to the screw terminal labeled CTR. The internal counter increments when the
TTL level transitions from low to high. The counter can count frequencies of up to 1 MHz.

Daisy chaining additional modules to the USB-DIO96H

Daisy chained MCC USB Series products connect to the USB bus through the high-speed hub on the USB­DIO96H. You can daisy chain a maximum of four MCC USB Series products to a single USB 2.0 port or USB

1.1 port on your computer. Use the supplied cable or an equivalent cable when daisy chaining MCC USB Series
products.

Depending on your load requirements, you may need to supply external power to each MCC USB Series
product that you want to daisy chain. Refer to the next section Power limitations using multiple USB-DIO96H

devices for more information.

MCC USB Series products are USB 2.0 full-speed devices that provide a signaling bit rate of 12 Mb/s. The
throughput rate is shared by all devices connected to the USB bus.

To daisy-chain two or more USB-DIO96H modules, follow the steps below. This procedure assumes you
already have one USB-DIO96H connected to a computer and to the external power source. The USB-DIO96H
already connected to the computer is referred to as the connected module. The USB-DIO96H you want to daisy­chain to the connected module is referred to as the new module.

Power limitations using multiple USB-DIO96H devices

When daisy chaining additional MCC USB Series products to the USB-DIO96H, you must ensure that you
provide adequate power to each board that you connect. The USB-DIO96H is powered with a 9 VDC nominal,

3.0 A external power supply.

Supply current

Running one USB-DIO96H at full load draws 2.6 A from the 3A supply. When using the USB-DIO96H under
full load conditions, you cannot daisy chain additional MCC USB Series products unless you supply external
power to each board in the chain.

If you are not sure how much current your application requires, we recommend that you provide separate power
to each MCC USB Series product that you connect.

Voltage drop

A drop in voltage occurs with each board connected in a daisy chain system. The voltage drop between the
input of one MCC USB Series product and the output of the board it is connected to is 0.5 V maximum. Factor
in this voltage drop when you configure a daisy chain system to ensure that adequate power is provided to the
last board in the chain. Always provide a separate power supply when the USB-DIO96H is the last board in the
chain.
