The board is a USB 2.0 high speed device, offering the fastest speed available with the USB 2.0 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 32 bits of TTL-compatible digital I/O with high-current capabilities. Each digital line can be programmed to accept an input or to drive an output. Power is supplied to the card via the USB cable or for higher source current capabilities, external power may be used. The I/O wiring connections are via an industry standard 50-pin connector or via an optional terminal block adapter card. For external circuits, fused +5VDC power is available at the connector. The resettable fuse is rated at 0.5A. All I/O lines are buffered by a type ABT tri-stateable buffer transceiver capable of sourcing 32 mA or sinking 64 mA. The buffers are configured under program control for input or output. I/O lines are pulled-up via 10KΩ to +5 VDC. For compatibility with industry standard solid state module mounting racks external power is required for the logic side of the module mounting rack as the load is typically greater than what can be provided over a USB port. 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. The board is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board is PC/104 size (3.550 by 3.775 inches) and can be ordered to ship inside a steel powder-coated enclosure with an anti-skid bottom. 6 Manual USB-DIO-32I Figure 1-1: Block Diagram Ordering Guide  USB-DIO-32I USB 32-individually selectable I/O digital module Model Options  -OEM Board only version with no enclosure  -E Economy version includes no screw terminal  -DIN DIN rail mounting bracket for integrating into existing DIN rail systems  -P On-board DC power circuitry and external power AC/DC adapter  -RoHS This product is available in a RoHS compliant version.

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  in the examples below. WINNT/2000/XP/2003 a. Place the CD into your CD-ROM drive. b. The CD should automatically run the install program. If the install program does not click START | RUN and type , 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. 8 Manual USB-DIO-32I Chapter 3: Hardware Details Option Selections Refer to the setup programs on the CD provided with the board. Also, refer to the Block Diagram when reading this section of the manual. USB Connector The USB connector is a Type B 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 current applications, an external power supply can be used. 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 Header The 50 pin box header has standard .100" spacing between pins and is keyed to prevent improper connections. It can be used with standard IDC type ribbon cables or the screw terminal board that plugs directly into the box header. 9 Manual USB-DIO-32I 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 board’s VID is “0x1605", and its PID is “0x8004". The Device Index is determined by how many of the device you have in your system, and provides a unique identifier allowing you to access a specific board at will. 10 Manual USB-DIO-32I 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 functions are provided by the driver in Windows. These functions will allow you to read or write individual bits, bytes, or the entire board worth of data. In addition, counter-timer functionality and board-level functions complete the driver package. For detailed information on each function refer to the .html Driver Manual located in the Win32 directory for this board. unsigned long GetDevices(void ) unsigned long QueryDeviceInfo(DeviceIndex, pPID, pName, pDIOBytes, pCounters) unsigned long DIO_Configure(DeviceIndex, bTristate, pOutMask, pData) unsigned long DIO_Write1(DeviceIndex, BitIndex, bData) unsigned long DIO_Write8(DeviceIndex, ByteIndex, Data) unsigned long DIO_WriteAll(DeviceIndex,pData) unsigned long DIO_Read8(DeviceIndex, ByteIndex,pBuffer) unsigned long DIO_ReadAll(DeviceIndex,Buffer) unsigned long CTR_8254Mode(DeviceIndex, BlockIndex, CounterIndex, Mode) unsigned long CTR_8254ModeLoad(DeviceIndex, BlockIndex, CounterIndex,Mode, LoadValue) unsigned long CTR_8254ReadModeLoad(DeviceIndex, BlockIndex, CounterIndex, Mode, LoadValue , pReadValue) unsigned long CTR_8254Read(DeviceIndex, BlockIndex, CounterIndex, pReadValue) unsigned long CTR_StartOutputFreq(DeviceIndex, CounterIndex, pHz) 11 Manual USB-DIO-32I Chapter 6: Connector Pin Assignments A 50-pin male header connector protrudes through a cutout in the enclosure for I/O connections.
