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 or 48 bits 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 two or four industry standard 50-pin connectors. 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 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. 6 Manual USB-DIO-96 Figure 1-1: Block Diagram Ordering Guide USB-DIO-96 USB 96-channel Digital Input/Output Module USB-DIO-48 USB 48-channel Digital Input/Output Module Model Options  -OEM Board only version with no enclosure  -RA Right angle headers (USB-DIO-48-OEM only)  -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.

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. WIN95/98/Me/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 , 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. 9 Manual USB-DIO-96 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. There are three primary versions of this board, each has an option selection map. Figure 3-1: 96 Channel Board Option Selection Map 10 Manual USB-DIO-96 Figure 3-2: 48 Chl OEM Board Option Selection Map Figure 3-3: 48 Chl OEM Board w/Right Angle Headers Option Selection Map 11 Manual USB-DIO-96 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 Mini 5-pin header in parallel with type B connector to provide a compact interface within embedded devices. 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. 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 pull- downs, install these jumpers in the GND position. For neither, remove these jumpers. 12 Manual USB-DIO-96 Chapter 4: USB Address Information Use the provided driver to Portwells 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. Both board versions (96 and 48 bit) VID is “0x1605". The 96 bit board version PID is “0x8003". The 48 bit board version PID is “0x8002”. The Device Index is determined by how many of the device you have in your system, and provides a unique identifier allowing you to Portwells a specific board at will. 13 Manual USB-DIO-96 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 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) 14 Manual USB-DIO-96 Chapter 6: Connector Pin Assignments Four 50-pin male headers are provided for I/O connections designated as P2, P3, P4 and P5.
