Functional Description
This USB board is an ideal solution for adding portable, easy-to-install digital I/O capabilities to
any computer with a USB port. The board is a USB 2.0 high speed device, offering the fastest
speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports.
The card is plug-and-play allowing quick connect/disconnect whenever you need additional I/O
on your USB port.
The board features 96 lines of TTL-compatible digital I/O with high-current capabilities. Each
digital port can be programmed to accept inputs or to drive outputs in 12 groups of 8-bit ports.
Power is supplied to the card via the USB cable or for higher current capabilities, external
power may be used. The I/O wiring connections are via four industry standard 50-pin
connectors. For external circuits, fused +5VDC power is available at the each connector. The
two resettable fuses are rated at 0.5A, with each fuse feeding two I/O connectors.
All I/O lines are buffered by a type 74ABT543A tristate buffer transceiver capable of sourcing
32 mA or sinking 64 mA. The buffers are configured under program control for input or output.
Jumper selectable pull-ups (to +5 VDC) or pull-downs (to ground) on the card allow for contact
monitoring and assure that there are no erroneous outputs at power-up until the card is
initialized by system software.
Unlike most USB digital I/O products which primarily use a human interface device (HID)
driver, we provide an easy to use, Windows-based, custom function driver optimized for
maximum data throughput. This approach exposes the full functionality of the hardware along
with maximizing the advantage of using the high-speed USB 2.0 bus.

Chapter 2: Installation
Software CD Installation
The software provided with this board is contained on one CD and must be installed onto your
hard disk prior to use. To do this, perform the following steps as appropriate for your software
format and operating system. Substitute the appropriate drive letter for your CD-ROM or disk
drive where you see G in the examples below.
WIN NT/2000/XP/2003
a. Place the CD into your CD-ROM drive.
b. The install program should automatically run. If it does not click START | RUN and type
GLQVWDOO, click OK or press ..
c. Follow the on-screen prompts to install the software for this board.
Hardware Installation
The board can be installed in any USB 2.0 or USB 1.1 port. Please refer to the USB I/O Quick
Start Guide which can be found on the CD, for specific, quick steps to complete the hardware
and software installation.

Chapter 3: Hardware Details
Option Selections
Refer to the setup programs on the CD provided with the board. Also, refer to the Block
Diagram and the Option Selection Map when reading this section of the manual.
Figure 3-1: 96 Channel Board Option Selection Map
USB Connector
The USB connector is a Type B high-retention type connector and mates with the cable
provided. The USB port provides communication signals along with +5 VDC power. The board
can be powered from the USB port or, if needed for higher source current applications, an
external power supply can be used.
Embedded USB Connector
Micro 5-pin header in parallel with type B connector to provide a compact interface within
embedded devices.
Manual USB-DIO-96 9
LED
The LED on the front of the enclosure is used to indicate power and data transmissions. When
the LED is in an illuminated steady green state, this signifies that the board is successfully
connected to the computer and has been detected and configured by the operating system.
When the LED flashes continuously, this signifies that there is data being transmitted over the
USB bus.
DC Power Jack (Optional)
This is an option for high current applications when more current is needed than what your
computer can provide on the USB port (typically 500 mA). The DC jack has a 2.00mm post on
board and is designed to be used with the 9 VDC AC/DC external power supply that ships with
this option. The voltage regulator on board regulates the 9 VDC and provides 5 VDC to the
onboard circuitry. When using external power, switch the jumper located near the USB
connector to VEXT, otherwise when the jumper is in the VUSB position current is drawn from
the USB port (please consult the option selection map for a visual reference).
50 Pin Box Headers
The 50 pin box headers have standard 0.100" spacing between pins and are keyed to prevent
improper connections. It can be used with standard IDC type ribbon cables.
5V Resettable Fused Outputs
Two 0.5A resettable fuses each feed two I/O connectors at pin 49 used to power external
module racks or relay boards, or for general purposes. If an over-current persists on a circuit
protected by a resettable fuse, it will open interrupting power to the circuit. The amount of time
it takes the fuse to act depends on the amount of over-current and other conditions such as
ambient temperature, humidity, etc. The fuse will remain open until the bi-metal elements cool
sufficiently, at which time the circuit will be restored.
Pull-Up / Pull-Down Configuration Jumpers
Each connector's digital bits can be pulled up or down, or left floating, when in input mode or
tristated. For pull-ups (most common), install these jumpers in the +5V position. For pulldowns, install these jumpers in the GND position. For neither, remove these jumpers.
Manual USB-DIO-96 10
Chapter 4: USB Address Information
Use the provided driver to access the USB board. This driver will allow you to determine how
many supported USB devices are currently installed, and each device’s type. This information
is returned as a Vendor ID (VID), Product ID (PID) and Device Index.
The VID is “0x1605" while the 96 bit board PID is “0x8003".
The Device Index is determined by how many of the devices you have in your system, and
provides a unique identifier allowing you to access a specific board.
Manual USB-DIO-96 11
Chapter 5: Programming
The driver software provided with the board uses a 32-bit .dll front end compatible with any
Windows programming language. Samples provided in Borland C++Builder, Borland Delphi,
Microsoft Visual Basic, and Microsoft Visual C++ demonstrate the use of the driver.
The following is a list of the most common function calls provided by the driver in Windows.
For a complete list of available functions and details on how to use them refer to the USB
Software Reference Manual located in the installation path for this board.
unsigned long DIO_Configure(DeviceIndex, bTristate, pOutMask, pData)
unsigned long DIO_Configure(
unsigned long DeviceIndex - number from 0-31 of the device you want to configure
unsigned char bTristate - boolean value. TRUE causes all bits on the device to enter tristate
(high-impedance) mode. FALSE removes the tristate. The tristate is changed after the
remainder of the configuration has occurred. All devices with this feature power-on in the
"tristate" mode at this time.
void *pOutMask - a pointer to the first element of an array of bytes; one byte per 8 ports or
fraction. Each "1" bit in the array indicates that the corresponding byte of the device is Output.
void *pData - a pointer to the first element of an array of bytes. Each byte is copied to the
digital output ports on the device before the ports are taken out of tristate. Any bytes in the
array associated with ports configured as input are ignored.
)
The size of the out mask and data is as follows:
Out Mask 2 bytes
Data 12 bytes
unsigned long DIO_WriteAll(DeviceIndex,pData)
unsigned long DeviceIndex - number from 0-31 of the device to which you wish to write all
output bits
void *pData - pointer to the first element of an array of bytes. Each byte is copied to the
corresponding output byte. Bytes written to ports configured as inputs are ignored
)
Note that the size of "all" is the same as the size of the data given under DIO_Configure.
unsigned long DIO_ReadAll(DeviceIndex,Buffer)
unsigned long DeviceIndex - number from 0-31 of the device from which you wish to read all
digital bits
void *Buffer - pointer to the first element of an array of bytes. Each port will be read, and the
reading stored in the corresponding byte in the array.
)
Note that the size of "all" is the same as the size of the data given under DIO_Configure.
