Error -1073807331 (0xBFFF001D) Using HP 34401A Instrument Driver in LabVIEWPrimary Software: LabVIEW Development Systems>>Full Development SystemPrimary Software Version: N/A Primary Software Fixed Version: N/A Secondary Software: Instrument Drivers/IVI, LabVIEW Development Systems
Problem: I am trying to communicate with my HP 34401A MultiMeter using my serial port and LabVIEW 6.1 in Windows 2000. When I try to run the Initialize.vi from the Functions Palette » Instrument I/O » Instrument Drivers » HP34401A MultiMeter, I receive the following message: Error -1073807331 occurred at Property Node (arg 9) in HP34401A Initialize.vi. What am I doing wrong? I have Version 4.2 of the HP34401A instrument driver. Solution: This error occurs on Windows 2000 and XP operating systems and is related to changing the Line DTR or Line CTS states of the serial port. We cannot modify the state of a line used for flow control while the hardware is in use, and these two operating systems return an error when that is attempted. Arguments 8 and 9 of the property node in the "Set Serial Settings" portion of the Initialize.vi Diagram set the DTR and CTS states, and with the flow control set to DTR/DSR in argument 3 of that property node, argument 9 becomes the guilty party. If the flow control was set to RTS/CTS, argument 8, dealing with the Line CTS setting, would then be causing this same error. Version 4.3 is available for download from our Instrument Driver Network (see link below). The problem is no longer present in that driver, as arguments 8 and 9 have been removed from the property node. Also, for later versions of LabVIEW, version 6.4 is available for later versions of LabVIEW (8.0 and later). Related Links: KnowledgeBase 2WO9BV59: Why is the HP34401A Getting Started.vi Timing Out?
