Chapter 1
Introducing the USB-DIO96H
The USB-DIO96H is supported under popular Microsoft® Windows® operating systems. The USB-DIO96H is
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.
You connect the field wiring directly to the device'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 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 associated DIP switches to drive the ports high or low during power up and reset (pull-up
or 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
termination 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). A USB cable is included.
The USB-DIO96H is powered by an external +5 V regulated power supply that is shipped with the board. A
jumper-selectable Molex® connector is also available inside the case if you need an alternate power supply (the
cable for this connector is not included).
This manual covers revision 2 hardware and later
This manual covers revision 2 of the USB-DIO96H hardware, which uses a 5 V power supply. Revision 1 of the
USB-DIO96H hardware has a 9 V power supply and daisy-chained hub. For information on revision 1
hardware, refer to www.mccdaq.com/PDFs/specs/USB-DIO96H_R1-spec.pdf.

USB-DIO96H block diagram
USB-DIO96H functions are illustrated in the block diagram shown here.
Figure 2. USB-DIO96H functional block diagram
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 has one jumper for configuring the power source.
The USB-DIO96H includes four groups of four dual in-line package (DIP) switches for setting the
pull-up/pull down configuration.
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 flow is bidirectional between a computer and peripheral over USB connections.

USB-DIO96H User's Guide Installing the USB-DIO96H
Installing the hardware
Before connecting the USB-DIO96H to a computer, connect the external power supply that was shipped with
the device.
Connecting the external power supply
Power to the USB-DIO96H is provided with the +5 V external power supply (PS-5V3AEPS). Connect the
external power supply before connecting the USB cable to the USB-DIO96H and the computer.
To connect the power supply to the USB-DIO96H, connect the external power cord to the power connector
labeled POWER IN on the USB-DIO96H enclosure (P5 on the board). Refer to Figure 3 on page 10 for the
location of this connector.
TheUSB-DIO96H has a PWR LED which illuminates green when +5 V power is supplied. If the voltage supply
is less than +4.13 V or more than +5.59 V, the PWR LED does not light and power is not supplied to the board
components.
Connecting the USB-DIO96H to your system
To connect the USB-DIO96H to your system, connect the USB cable to an available USB port on the computer
or to an external USB hub that is connected to the computer. The USB cable provides communication to the
USB-DIO96H.
When you connect the USB-DIO96H for the first time, multiple Found New Hardware popup balloons open
when the operating system detects the device. When installation is complete, the USB LED should flash and
then remain lit. This indicates that communication is established between the USB-DIO96H and the 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
Perform the following procedure if a "USB device not recognized" message appears when you connect the
USB-DIO96H:
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.
