Page 6: Introducing The Usb-7202
The USB-7202 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). -

Page 8: Installing The Usb-7202
Contact us immediately if any components are missing or damaged. Installing the software Refer to the MCC DAQ Quick Start and the USB-7202 product page on our website for information about the software that supports the device. Install the software before you install your device The driver needed to run the USB-7202 is installed with the software. -
Page 9: Calibrating The Hardware
Calibrating the hardware Factory calibration The Measurement Computing Manufacturing Test department performs the initial factory calibration. Contact Measurement Computing for details about how to return your device and have it calibrated to the factory specifications. Field calibration The USB-7202 supports field calibration. Calibrate the device using InstaCal whenever the ambient temperature... -

Signal connections Analog input You can connect up to eight analog input connections to screw terminals through . -
Page 14: Sync I/O
The USB-7202 alone draws 150 mA of current from the USB +5 V supply. Once you start running applications with the USB-7202, each DIO bit can draw up to 2.5 mA. The maximum amount of +5 V current available for experimental use, over and above that required by the USB-7202, is the difference between the total current requirement of the USB-7202 (based on the application) and the allowed current draw of the computer platform (500 mA for desktop computers and self-powered hubs). -
Page 15: Ground
The primary error sources in the USB-7202 are offset and gain. Nonlinearity is small in the USB-7202, and is not significant as an error source with respect to offset and gain. Figure 6 shows an ideal, error-free, USB-7202 transfer function. The typical calibrated accuracy of the USB- 7202 is range-dependent, as explained in the Specifications chapter on page 19. - Page 16 Combining these two error sources in Figure 9, we have a plot of the error band of the USB-7202 at ±full scale (±10 V). This plot is a graphical version of the typical accuracy specification of the product.

Page 17: Synchronized Operations
Figure 9. Error band plot Synchronized operations You can connect the SYNC pin of two USB-7202 devices together in a master/slave configuration and acquire data from the analog inputs of both devices using one clock. When the SYNC pin is configured as an output, the internal A/D pacer clock signal is sent to the screw terminal. -
