Error -200077 in Measurement and Automation Explorer when I tried the waveform output constinuous generation

[Célio]

I make a output task in Measurement and Automation Explorer: a output waveform in continuous mode - one channel: Ao0

frequency  1k, rate 1k ,sine wave, 5V amplitude.

The software  returns

Error -200077 occurred at DAQ Assistant

Possible Reason(s):
Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.

The same throuble occured when I tryed to execute VB.net and VB6 sample codes (from natinst) in a timing  function  (DAQmxCfgSampClkTiming)

"Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property.
"

Used code (VB6):

DAQmxErrChk DAQmxCreateAOVoltageChan(taskHandle, "Dev1/ao0", "", "0.00", "5.00", DAQmx_Val_VoltageUnits2_Volts, "")
DAQmxErrChk DAQmxCfgSampClkTiming(taskHandle, "",1000#, DAQmx_Val_Edge1_Rising, DAQmx_Val_AcquisitionType_ContSamps, 1000)

Base software  DAQmx 7.5    and    Windows XP

Hardware  NI-USB 6009

This exact same error with this device has been posted numerous times.

Your device has no clocked output so using the timing function results in the error. You can only write one point at a time and at no more than the max specified in the specs and with considerable jitter.

Tank you.  I already had read in the Manual after my question.
