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).
