I have a new 6361 and just started using LV 2010. Not used DAQmx before. I want to output waveforms on P0.0 - P0.2 at 10 MHz. Modified example "Cont Write Dig Port-Int Clk.vi" to make the waveforms. I got it to work up to 6MHz after adding a lot of unwanted "dead time" samples per 2 below. Adding even more samples only got me this error: Error -200290 occurred at Property Node DAQmx Task (arg 1) in DAQmx Is Task Done.vi:1->Cont Write Dig Port-Int Clk.vi Possible reason(s): The generation has stopped to prevent the regeneration of old samples. Your application was unable to write samples to the background buffer fast enough to prevent old samples from being regenerated. To avoid this error, you can do any of the following: 1. Increase the size of the background buffer by configuring the buffer. 2. Increase the number of samples you write each time you invoke a write operation. 3. Write samples more often. 4. Reduce the sample rate. 5. Change the data transfer mechanism from interrupts to DMA if your device supports DMA. 6. Reduce the number of applications your computer is executing concurrently. In addition, if you do not need to write every sample that is generated, you can configure the regeneration mode to allow regeneration, and then use the Position and Offset attributes to write the desired samples. Task Name: _unnamedTask<12> 1. I tried using DAQmx Configure Output Buffer to no avail 2. Worked to a point as above 3. Only write samples once 4. What I don't want 5. The Specification says the 6361 has DMA but I can't find anything on it 6. Minimized The spec also says the output can go to 10MHz using Regenerate from FIFO but I can't find anything on it either. Can anyone help? Thanks in advance, STM99

error 200290 with 6361

John & Jesse, I reinserted the On-board regen and the added the reset to my vi. I can now run at 10 MHz with a minimum of bits - no extra "dead bits" needed. Thank you both very much. STM
