HIGH-SPEED USB 2.0 MODULE
ACCES I/O Products,
Inc., revealed its
newest digital I/O product —
Model USB-DIO- 32. This
USB device is an ideal solution for adding portable,
easy-to-install, digital I/O
and counter capabilities to
any PC or embedded system
with a USB port. The unit is a
true USB 2.0 device, offering
the highest speed available with the USB bus. It is fully
compatible with both USB 1.1 and USB 2.0 ports. The unit
is plug-and-play, which allows quick connect or disconnect
whenever you need additional I/O on your USB port. The
USB-DIO- 32 can be used in a variety of applications such
as home, portable, laptop, education, laboratory, industrial
automation, and embedded OEM.
The USB-DIO- 32 features 32 lines of TTL-compatible
digital I/O on four eight-bit ports with high-current output
capabilities and three optional 82C54 counters. Power is
supplied to the device via the USB cable or, for higher current applications, an external power option is available.
Unlike other USB digital I/O products, which primarily
use a human interface device (HID) driver, ACCES offers
an easy-to-use, Windows-based, custom function driver
optimized for maximum data throughput. This approach
enables the full functionability of the hardware along with
maximizing the advantage of using the high-speed USB 2.0
bus.

• High-speed USB 2.0 device, USB 1.1 compatible
• Small ( 3. 5” x 3. 7”), portable, 32-channel USB digital I/O
