The USB-DIO-16H features 16 high-speed buffered digital inputs or digital outputs capable of continuous, sustained streaming speeds up to 16 MB/s for fast, unlimited waveform pattern generation. The module can provide 80 MB/s data bursts with handshaking signals for synchronizing communications. The onboard 1 kHz - 40 MHz programmable clock determines the data transfer rate. An external clock input is also available.

In addition the USB-DIO-16A provides 18 bits of general purpose TTL-compatible digital I/O configurable as 4 separate ports for input or output.

The series includes two I/O models the USB-DIO-16H with 128Kbyte FIFO data buffers and the USB-DIO-16A with 8Kbyte buffers. An input only model, the USB-DI16A and an output only model, the USB-DO16A is also available.

The USB-DIO-16H is port-powered via the USB cable, however for higher current sourcing capabilities an optional external power pack may be used. The USB-DIO-16H is a high-speed USB 2.0 device and offers hot swapping functionality for quick connect/disconnect whenever you need additional I/O on your USB port.

The USB-DIO-16H was designed for rugged industrial environments. All models feature high retention USB connectors and are housed inside a steel powder-coated enclosure with an anti-skid bottom.

External I/O wiring is connected via a high-density pin-in-socket SCSI connector. The I/O connector also provides +5VDC to power external circuits.

The board itself is PC/104 sized (3.550 by 3.775 inches) and has pre-drilled mounting holes that match the PC/104 form factor. The OEM (board only) version is perfect for embedded applications and can be added to any PC/104, PCI-104, or PCI/104-Express stack by connecting it to a USB 2.0 port on the embedded CPU board.

The USB-DIO-16H will work with most USB supported operating systems and includes a free Windows 98se/Me/2000/XP/2003/Vista and Embedded Windows XPe compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows.
