Figure 2.5、Analog input range setting 2.6 Analog input calibration A new PCI-1255 DAQ card will be factory-calibrated as 32 channels singled ended input with 0~10V range. It can be deployed right after basic verification. If there is any change on channel input or range, it must be calibrated once again to make sure the DAQ card can acquire the correct data. -

6、 Now the DAQ card hardware is installed. Restart the computer. 3.2 Installing driver On a PC running Windows OS, if you installed Smacq PCI-1255 DAQ card without its driver, you will see an unknown device with exclamation in the Windows device manager. Please follow the steps below to install the driver correct (this manual will base the steps on 32-bit Microsoft Windows 7, which are all the same on other Windows versions.) -
