I am trying to using LabVIEW 8.2 with a USB 1208LS device; however, I am
unable to get LabVIEW to recognise it. When using the DAQ assistant, it doesn't show up in the list of DAQ devices, regardless of whether or not I select one of the Inputs or Outputs. It also does not show up in the Instrument I/O Assistant. The relevant User Libraries are all installed. This DAQ
device is recognised correctly by Windows (with the correct drivers), InstaCal and TracerDAQ. When attempting to calibrate it in InstaCal, I get an error: "Max bipolar offset code reached", or "Min bipolar offset code reached" when I have the pins connected as instructed. It behaves as expected in TracerDAQ when set to 4 Differential mode in InstaCal, but when set to 8 Single Ended mode TracerDAQ displays an error on startup and does not display any devices to read as it normally would. I have tried using it on two different computers, one running Windows 2000 Professional, the other running Windows XP Professional. Both give the same results: communication with InstaCal and TracerDAQ, correctly configured in Windows, but nothing in LabVIEW's DAQ assistant or I/O assistant.
A pressure gauge controller is connected to the COM1 serial port. LabVIEW happily communicates with this. It also communicated successfully with a PCI DAQ device. This USB 1208LS is from Measurement Computing. I saw that Adept Scientific also sell a USB 1208LS device, but the two products had the same specification and even looked the same in the product image. Any ideas would be much appreciated. Thanks in advance.
