Chroma 61604 Serial Connection through USB Adapter

[K_G_ThermoScience]

Hello,

I am using a Chroma 61604 AC power Source.  The driver which I am using can be found here: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9172659CE034080020E748....  I am connecting it to a computer running Windows XP through a USB serial adapter.  The driver says it is GPIB compatible. When trying to communicate to the device I get the following error:

Error: BFFF0072

Reference valid but VISA cannot currently access it.

I am not very knowledgable in creating drivers, how can I modify this driver to be serial compatible (if that is the problem)?  Or do I need to use a GPIB to USB converter?

Thanks for your time,

Kyle Goyette

Hi Kyle,

The BFFF0072 error is indicating that the serial port you are trying to configure is being used.

Moving forward:

• Verify that no undesired resources are using the port.
• Use the VISA Close VI in LabVIEW to close existing referances: http://digital.ni.com/public.nsf/websearch/6807113B057FDE4C86256B41008212ED?OpenDocument

Please update on if this helps you move past the error.
