Error -1073807342

Description and Solution

  • This error is caused when the Resource Name passed to VISA Open is incorrect. The following text shows proper syntax for Resource Name:

  • If you use GPIB addresses, the following syntax is used:
    • GPIB[board]::primary address[::secondary address][::INSTR]
    • Example: GPIB::4 means address 4 of GPIB board 0
    • Example: GPIB2::9[::3][::INSTR] means GPIB board 2, primary address 9, secondary address 3
  • If you use Serial ports, the following syntax is used:
    • ASRL[board][::INSTR]
    • Example: ASRL1 means com port 1
    • Example: ASRL2 means com port 2
    • Example: ASRL10 means LPT port 1
    • Example: ASRL11 means LPT port 2
    • Note: If you are used to the old Serial VI's, this syntax is different. (With VISA, ASRL1 means Com 1.)

NOTE: LabVIEW online help for the VISA Open function gives more detail for all of this information
