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, unlim-

ited waveform length. The module is capable of 80 MB/s bursts with handshaking signals for synchronizing communications plus an additional 18 bits of gen-

eral 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 re-

quired 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.
