This user guide describes how to use the National Instruments USB-6008/6009 data acquisition (DAQ) devices and lists specifications.

Introduction
The NI USB-6008/6009 provides connection to eight analog input (AI) channels, two analog output (AO) channels, 12 digital input/output (DIO) channels, and a 32-bitcounter with a Full-Speed USB interface.
Note

This manual revision updates naming conventions to reflect the conventions used in NI-DAQmx. Table 1 notes the correlation between the old and updated names.

Caution

Do not operate the device in an explosive atmosphere or where there may be flammable gasesor fumes. If you must operate the device in such an environment, it must be in a suitably rated enclosure. If you need to clean the device, use a dry cloth. Make sure that the device is completely dry and free from contaminants before returning it to service. Operate the device only at or below Pollution Degree 2. Pollution is foreign matter in a solid, liquid, or gaseous state that can reducedielectric strength or surface resistivity. The following is a description of pollution degrees: • • Pollution Degree 1 means no pollution or only dry, nonconductive pollution occurs. The pollution has no influence. Pollution Degree 2 means that only nonconductive pollution occurs in most cases. Occasionally, however, a temporary conductivity caused by condensation must be expected. Pollution Degree 3means that conductive pollution occurs, or dry, nonconductive pollution occurs that becomes conductive due to condensation.



You must insulate signal connections for the maximum voltage for which the device is rated. Do not exceed the maximum ratings for the device. Do not install wiring while the device is live with electrical signals. Do not remove or add connector blocks when power is...
