FUNCTIONAL DESCRIPTION
Model USB-DIO-16H features 16 high-speed buffered digital inputs or digital outputs at continuous, sustained streaming speeds up to 16 MB/s for fast, unlimited
waveform length. The module is capable of 80 MB/s bursts with handshaking signals for synchronizing communications plus an additional 18 bits of general
purpose digital I/O. The USB-DIO-16H is a port-powered high-speed USB 2.0 devices and offers hot swapping functionality for quick connect/disconnect
whenever you need additional I/O on your USB port.
The USB-DIO-16H includes a programmable clock capable of 1 kHz - 40 MHz transfers or you may choose to use your own external clock. In addition to the 16
high-speed I/O’s there are 18 standard TTL-compatible digital I/O channels configurable as 4 separate ports for input or output (see block diagram). All required
power is normally supplied to the board via the USB cable, however for higher current sourcing capabilities, optional external power may be used. The
I/O wiring connections for the units are via an industry standard high-density pin-in-socket SCSI connector. For external circuits, a jumper selection connects
fused +5VDC power to the connector. This resettable fuse is rated at 0.5A.
The series includes four models, choose from input only (USB-DI16A), output only (USB-DO16A), and input/output versions (USB-DIO-16A) with expandable
FIFOs (USB-DIO-16H). These modules are especially useful where high-speed data needs to be captured or output for testing or stimulus/response applications.
These include testing and debugging, laboratory automation, manufacturing test, image capture, process monitoring, datasource emulation, and many
more which require the need for high-speed parallel data transfer.
A type B USB connector is used on all models which features a high retention design that complies with the class 1, Div II minimum withdrawal requirement of
over 3 pounds of force. This connector has an orange color-coded insulator to differentiate it from standard USB connectors.
The USB-DIO-16H was designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board itself
is PC/104 sized (3.550 by 3.775 inches) and ships with or without a steel powder-coated enclosure with an anti-skid bottom. A DIN rail mounting provision is
available for installation in industrial environments.
OEM USB/104 FORM FACTOR
The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique is that its PCB size and pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. The board can be added to any PC/104, PCI-104, or PCI/104-Express stack by connecting it to a USB 2.0 port usually included on-board with embedded CPU form factors such as EBX, EPIC, and PC/104. This is especially important since many newer CPU chipsets do not support ISA and have plenty of USB ports. The USB-DIO-16H OEM board can also be installed using standoffs inside other enclosures or systems. For embedded OEM type applications, an additional miniature USB input header is provided in parallel with the type B connector.
High Retention USB Connector
The ever-growing presence of USB in the industrial/military marketplace has driven the need for USB connections to be reliable, dependable, and unfailing. Gone are the days of loose USB connections. A type B USB connector is used on all USB/104 products which features a high retention design that complies with the class 1, Div II minimum withdrawal requirement of over 3 pounds of force (15 Newtons). This connector has an orange color-coded insulator to quickly differentiate it from standard USB connectors. Using these USB connectors increases reliability in your system and ensures a tight connection. For embedded OEM type applications, an additional miniature USB input header is provided in parallel with the type B connector.
APPLICATIONS
- Testing and Debugging
- Laboratory Automation
- Manufacturing Test
- Image Capture
- Process Monitoring
- Datasource Emulation
- Embedded OEM
ACCESSORIES
Available accessories include a shielded, round-wire molded cable with latching connectors and a 68-pin screw terminal board for quick and easy connectivity.
SOFTWARE
The USB-DIO-16H utilizes a high-speed custom function driver optimized for maximum continuous data throughput of 16 MB/s that is hundreds to thousands of times faster than the USB human interface device (HID) driver used by many competing products. This approach maximizes the full functionality of the hardware along with capitalizing on the advantage of high-speed USB 2.0. The boards are supported for use in most USB supported operating systems and includes a free Windows 98se/Me/2000/XP/2003/Vista compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Third party support includes a Windows standard DLL interface usable from the most popular application programs and includes example LabView VIs. Embedded OS support includes Windows XPe.
