Hi
I have been using edgeport hub to communicate with an instrument which has multiple RS232 and one GPIB interace. The GPIB is connected to edgeport using GPIB-USB-HS. Max and LV 2010 communicates to edgeport via single USB. This set up is sucessfully used on a development PC (Win 7). Last week I moved the set up to a test machine which has additional RS232 and PCI-GPIB on it. I think the move was successful. however, one time edgeport experienced a power fluctuation and since then I am not able to communicate with GPIB-USB-HS. In LabVIEW I am using GPIB clear, GPIB trigger and GPIB write in sequence.
I have attached current MAX setting for the GPIB-USB-HS and the VI i am using. GPIB clear and trigger says 'OK' while GPIB write ends up with 'Error 3'. I have looked into error codes here. The primary address is '3' and I am using that.
Interestingly when I went back to development machine, I am facing the same issue. Unfortunately, I forgot to document the MAX setting (only capture settings and forgot connections) , realizing how fool I am!
Our old set up which directly takes GPIB cable (therefore no involvment of GPIB-USB-HS) works well.
Did the power fluctuation affect the GPIB-USB-HS?
