Error Code 250033 I recieve the following error when using a PCI NI digital waveform generator/analyzer. What could be the cause? Error -250033 occurred: NI-TClk committed a session, and the instrument driver reported an error. URL: http://digital.ni.com/public.nsf/allkb/7AD9D646FEA83270862573C60071DCBC

Why Do I Receive Error -1074118592 When Using the niHSDIO Write Named Waveform VI? I am trying to generate a digital waveform using the NI-HSDIO instrument driver and supported hardware. When I use the niHSDIO Write Named Waveform VI I get the following message: Error -1074118592 occurred at niHSDIO Write Named URL: http://digital.ni.com/public.nsf/allkb/F6642877E0D9D0698625738B0007701E

Possible Sources of HSDIO Acquisition Error with NI 655x I am performing a acquisition with an NI 6551 or NI 6552 device, and I am not acquiring the data that I know I should be. Furthermore, I have a oscilloscope or digital multimeter on the lines and I notice that the logic levels are not what I expect. What is going on?

使用 NI 655x 擷取信號錯誤的可能原因 我使用 NI 6551 或 NI 6552 擷取信號，但是卻沒有收到我預期的正確信號；我同時使用一台示波器與一台數位電表量測信號線，並且發現信號的邏輯準位〈logic level〉不是我所預期的。請問這是發生了什麼事？ URL: http://digital.ni.com/public.nsf/allkb/E0923B9E39054CF3862573B40039C3CC

Differences Between RTSI/PXI Lines And PFI Lines In HSDIO Devices I am seeing unexpected behavior when using the RTSI/PXI lines of my HSDIO devices. What am I doing wrong? URL: http://digital.ni.com/public.nsf/allkb/2DDA995A6FBA07EE8625737500680143

Can the 6533 be Tristated? I have a 6533 on which I am looking to do bi-directional communication. I would like to tristate one of the lines and need to know if this is possible. URL: http://digital.ni.com/public.nsf/allkb/65079CF2ADF329CA862573400065459B

Hardware Red LED When Using External Clock I am using one of the NI-HSDIO cards (654x, 655x or 656x) with an external clock. Even if I stop the external clock after my acquisition/generation, the front panel red LED lights up and I cannot make it go away. Why is this LED turning on and how can I fix this?

Where Can I Find Dimensions for the LVDS Infiniband Right-Angle Connector, Part 779157-01? I need the dimensions for the right-angle LVDS connector (part 779157-01) for a customized PXI application. Where can I find a drawing with the necessary information? URL: http://digital.ni.com/public.nsf/allkb/16780B2E6885D673862573140047E328

Bus Speed for PCIe-6537/6536 NOTE : Since PCI Express is a serial based technology, data can be sent over the bus in two directions at once. Normal PCI is Parallel, and as such all data goes in one direction around the loop. Each 1x lane in PCI Express can transmit in both directions at once.
