I am attempting to use RS-485 to communicate with a temperature controller in LabVIEW. Based on the example program for RS-485 communication, I am using a property node to set the wire mode to RS485/Wire2-Auto. However, when I do this, I get the error "Error -1073807330 occurred at Property Node, The specified state of the attribute is not valid, or is not supported as defined by the resource."
The LabVIEW help for the wire mode property says that for RS485 hardware, the property is only valid with the RS485 serial driver developed by National Instruments. I assume that's the problem, and that I don't have that. However, I have been unable to figure out where to find a download for this driver, and can find no other reference to its existence apart from this note in the help reference.
Does anyone know what this driver is, and how to download/use it? Any help would be appreciated.
Thank you very much.
