Introducing the USB-1608GX-2AO

The USB-1608G is a USB 2.0 high-speed device that provides the following features:

 16 single-ended (SE) or eight differential (DIFF) analog input channels

 Two analog output channels

 Eight individually configurable digital I/O channels

 Two counter channels (32-bit) that count TTL pulses

 One timer output channel (32-bit)

 Screw terminals for field wiring connections

The USB-1608GX-2AO is powered by the +5 volt USB supply from your computer; no external power is

required. A USB cable is shipped with the device.

The USB-1608GX-2AO device is compatible with both USB 1.1 and USB 2.0 ports. The speed of the device

may be limited when using a USB 1.1 port due to the difference in transfer rates on the USB 1.1 versions of the

protocol (low-speed and full-speed).
