From: Michael Purdy on 19 May 2010 13:54 I am trying to build a device to turn on/off both a laser and a voltage source. I am hoping to use a piece of hardware such as the NI USB 6008 (http://sine.ni.com/nips/cds/view/p/lang/en/nid/202751) to send data bits to turn on/off these devices, and I was wondering if it is necessary to have the Data Acquisition Toolkit even if I am not making any measurements or reading data at all. Thanks. Michael

That hardware comes with a driver, so at worst you could use a little bit of C code to open and write to the device. I would, however, recommend that you cross-check the specifications of that device. According to that page, the outputs (the part you want to use) can only handle 150 samples per second. I went through and checked the user manual and it does not have any information about sample rate. The 16 bit devices are rated at 250 kilosamples per second, so I suspect that the 'k' is accidentally missing -- but you would want to cross-check that. For example, the 6009 device does have data sheet, and that data sheet does indicate 150 for the 6009, with the unit being given as Hz, so it is possible that the 6008 really is limited to 150 samples/second output. |
