Chapter 1
Introducing the USB-DIO96H/50
The USB-DIO96H/50 is supported under popular Microsoft®Windows®operating systems. The
USB-DIO96H/50 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-DIO96H/50 provides 96 digital I/O lines, high output current.
The 96 digital I/O lines are accessed through two 50-pin connectors. 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/50 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 during power up and reset. You can
optionally set these switches for a pull-down configuration. All I/O bits are set to input mode on power up and
reset.
The USB-DIO96H/50 is shipped in a rugged metal enclosure that you can mount on a DIN rail or on a bench
(refer to Figure 9on page 13).
The USB-DIO96H/50 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 applies to revision 2 hardware and later
This manual applies to revision 2 of the USB-DIO96H/50 hardware, which uses a 5 V power supply. Revision 1
of the USB-DIO96H/50 hardware has a 9 V power supply and daisy-chained hub. For information on revision 1
hardware, refer to www.mccdaq.com/PDFs/Manuals/USB-DIO96H-50_R1.pdf.

Chapter 2
Installing the USB-DIO96H/50
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the device 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.
Contact us immediately if any components are missing or damaged.
Installing the software
Refer to the MCC DAQ Quick Start and the USB-DIO96H/50 product page on our website for information
about the available software.
Install the software before you install your device
The driver needed to run the USB-DIO96H/50 is installed with the software. Therefore, you need to install the
software package you plan to use before you install the hardware.
Connecting the external power supply
Power to the USB-DIO96H/50 is provided with the +5 V external power supply (PS-5V3AEPS). You must
connect the external power supply before connecting the USB cable to the device and your computer.
To connect the power supply to the USB-DIO96H/50, connect the external power cord to the power connector
labeled POWER IN on the USB-DIO96H/50 enclosure (P5 on the board). Refer to Figure 2 on page 8 for the
location of this connector.
The PWR LED lights up when +5 V power is supplied to the USB-DIO96H/50. If the voltage supply is less
than +4.1 V or more than +5.6 V, the PWR LED does not turn on.
Installing the hardware
Connect the USB-DIO96H using the cable provided to a USB port on a computer running Windows. Windows
finds and installs the device driver automatically and notifies you that the device is ready to use.
Caution! Do not disconnect the device from the USB bus while the USB LED is on and the computer is
communicating with the USB-DIO96H. You may lose data and/or your ability to communicate
with the USB-DIO96H.
If the USB LED turns off
If the USB LED turns on 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.
If your system does not detect the USB-DIO96H/50
Perform this procedure if a USB device not recognized message displays when you connect the device:
1. Unplug the USB cable from the USB-DIO96H/50.
2. Unplug the external power cord from the POWER IN connector on the enclosure.
3. Plug the external power cord back into the POWER IN connector.
4. Plug the USB cable back into the USB-DIO96H/50.
Your system should now properly detect the USB-DIO96H/50 hardware. Contact technical support if your
system still does not detect the USB-DIO96H/50.

The USB-DIO96H/50 is connected to a computer or external USB hub.
Continuous blink
Initial communication is established between the device and the computer, or data is being

PWR LED
The PWR LED turns on when external power is supplied. The USB-DIO96H/50 incorporates an on-board
voltage supervisory circuit that monitors the external power supply and disconnects power from the rest of the
board components if the external power supply voltage is too high or too low. The PWR LED does not light
under the following circumstances:
when the input power falls below +4.1 V
when the input power goes above +5.6 V
