Instrument I/O Assistant

[OrangeEngr]

I am using a chip called the USB I/O 24 DIP to transfer data through the USB port.  I have installed the correct driver, and the operating system as well as Labview recognizes it.  I can use the Instrument I/O assistant just fine for the identify device command "?", however when I try to send "b" which reads from post B of the chip and then read and parse the data, I get a timeout error on the read and parse step of the assistant.  I am recieving the correct data from the port in the read and parse window, but I can not access it because it times out.  It needs to finnish the run in order for me to parse the data so I can access it from the assistant block.  Can anyone help me?

Here is the data sheet for the USB I/O 24 DIP http://elexol.com/Downloads/USBIO24DIPDS1.pdf

Hi,

Are you able to communicate with the instrument using VISA commands directly? The Instrument I/O Assistant will be communicating with your instrument using VISA. Below are some basic write and read examples for VISA. I saved them in different versions of LabVIEW, because you didn't say what version you were using. Please let me know if you need it saved into a different version. Using these VIs, are you able to get the data back? Does it still timeout?
