USB-3114 Measurement Computing USB Data Acquisition Device

The Measurement Computing USB-3114 USB Data Acquisition Device is a USB 2.0 full-speed, high-drive device that is supported under popular Microsoft Windows operating systems. The USB-3114 is fully compatible with both USB 1.1 and USB 2.0 ports. The USB-3114 provides 16 channels of high-drive analog voltage output, high output current, eight digital I/O connections, and one 32-bit event counter. Each of the voltage outputs of the USB-3114 incorporates high-drive current output capability. The USB-3114 USB Data Acquisition Device's high drive current outputs allow each of the voltage outputs to sink/source up to 40 mA (maximum) of load current.

The USB-3114 has four quad (4-channel) 16-bit digital-to-analog converters (DAC). 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 outputs may be updated individually or simultaneously. The USB-3114 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. A bidirectional synchronization connection allows you to simultaneously update the DAC outputs on multiple devices. All I/O connections are made to the screw terminals located along each side of the USB-3114 USB Data Acquisition Device.
