The Measurement Computing USB-DIO32HS is a high-speed digital I/O device and features 32 channels, up to 8 MS/s update rate, independent input and output scan clocks, and digital and pattern triggering. The 32 DIO bits are available as two 16-bit ports that are bit-configurable for input or output. Each port is configured independently, so both software polling and hardware scanning operations can be performed at the same time. This device is USB-powered and requires no external power.

Either digital port can output a 16-bit digital pattern. The pattern is updated at a rate up to 8 MS/s, and clocked using the output scan clock. Use both ports to output a 32-bit digital pattern. Data from one port is read and stored in the FIFO buffer until the second port is read. Both ports are output simultaneously on the rising edge of the next pacer clock signal.

The 32 DIO bits are available as two 16-bit ports that are bit-configurable for input or output. Each port is configured independently, so both software polling and hardware scanning operations can be performed at the same time. When performing software polling, the port can contain any combination of input or output bits. When performing hardware-paced output scans, all bits in the port must be set for output. For input scans, however, the current state of any bits in the port that are configured for output are read.

Users can pace input scanning operations with the onboard input scan clock or with an external signal. The input clock frequency is 8 MHz, maximum. A duty cycle of 50% is maintained when the internal input clock paces operations. When using an external clock, the signal is output immediately after the external clock input is received.

Digital and pattern triggering are supported. The TRIG pin is used for external TTL-level triggering, and can be used to trigger input or output scans. Trigger latency is less than 1 s. The trigger mode is software selectable for edge or level sensitive, and high or low logic. Either digital port can be used for pattern triggering. A scan is triggered when a specified pattern is detected. Specific bits can be masked or ignored. Trigger latency is 1 scan clock period. You can input or output a digital pattern under the timing control of a clock signal.

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, Linux, and Python.
