Description

Description
The USB-3101 is a USB 2.0 full-speed device that is supported under popular Microsoft® Windows® operating systems. The USB-3101 is fully compatible with both USB 1.1 and USB 2.0 ports.
The USB-3101 provides four channels of analog voltage output, eight digital I/O connections, and one 32-bit event counter.
The USB-3101 has a quad (4-channel) 16-bit digital-to-analog converter (DAC). You set the voltage output range of each DAC channel independently with software for either bipolar or unipolar. The bipolar range is ±10 V, and the unipolar range is 0 to 10 V. The analog outputs may be updated individually or simultaneously. A bidirectional synchronization connection allows you to simultaneously update the DAC outputs on multiple devices.
The USB-3101 features eight bidirectional digital I/O connections. You can configure the DIO lines as input or output in one 8 bit port. All digital pins are floating by default. A screw terminal connection is provided for pull up (+5 V) or pull-down (0 volts) configuration.
The 32-bit counter can count TTL pulses.
The USB-3101 is powered by the +5 volt USB supply from your computer. No external power is required. All I/O connections are made to the screw terminals located along each side of the USB-3101.
