Read from serial-usb converter?

[SnowMule]

strange... I've had no issues getting USB-Serial converters working on any of my systems, both XP and 7.  Install the drivers, plug the hardware in, go to device manager and see what COM port it comes up as, then use that COM port through VISA.

We use IOGear GUC232A's and SILabs CP2102's.  The 2102 has *nix/Mac drivers too, which is nice.

Hi, i will second what NIquist just said about USB to serial converters(one that i bought didnt work with labview either). Once you install the drivers of a USB to Serial Covnerter, it appears as a COMx port on your computer, Check it out by right clicking on My Computer>Properties. There is a tab on the left that says Device Manager, click on it. Expand the option that says COM and LPT ports. There you are going to find your USB to serial converter port name(which its driver will assign during installation), Once this is done, start the Measurement and Automation Explorer and run the VISA test panel on the COM port. It will either work properly or not( give different errors). Once you install the coverter drivers, the PC should see it as a COM port not a USB port(hence giving the error of the USB IDs. First make sure that your USB to serial converter is working on your PC or not(use a serial monitor to do that, connect RX and TX together, send ome data and if you receive the data back than it indicates that it is working).

I just ran the driver setup wizard in visa and got this error for the keyspan dongle.

There is no 'driver setup wizard in visa' that should be run. Huge mistake if you did this and actually created an inf file that windows used. If it did get created, you MUST remove it and use the driver that came with the device. It MUST first appear in windows as a com port and then it should automatically appear in MAX.

You then select the com port exactly like you would a built-in. Select the pull-down on the VISA Resource Name control and select the port from the list
