Hi, I am trying to communicate with an acton monochromator 300i.
When I use VISA, I can communicate just fine. When I try to use either of the labview examples (GPIB-VISA and GPIB-Labview) as well as my own program, I cannot, and I get a timeout error.
I have read a page about this kind of problem here: http://digital.ni.com/public.nsf/allkb/6217D314252A51168625693F004FD873
It says, I should change the address of my device to 0. (the default adress of my device is 11) .However I can only set the address of my device between 1 and 30, so this solution does not work for me.
I have tried using the property nodes to chand the termination charater settings, I have tried the commands with and without termination character (which is \r in this case), I have tried putting a delay between the write and read, I have tried reducing the "bytes to read" and nothing has worked
Here is what the error says:
Error -1073807195 occurred at VISA Open in GPIB-VISA_modif.vi
VISA: (Hex 0xBFFF00A5) The interface type is valid, but the specified interface number is not configured.
Any help is appreciated.
Hi, Thank you for your reply.
We have the national instrument PCI-GPIB bus.
I believe the controller has the address 0 already from what I can tell. I have attached the screen shots of the MAX devices and interfaces tabs for GPIB.
I am not sure what is meant by "Visa resource name" but the name of the device shows up as GPIB11::11::INSTR.
