Hi,
I recently started a new job and have been having communication issues between my GPIB-USB-HS adapter, my USB-8451 I2C/SPI interface, and Labview/MAX/VISA. I installed 32-bit LabView, NI-488.2, VISA 16.0 and the driver for the 8451 onto my windows 7 desktop.
In windows device manager, the 8451 shows up as an NI-VISA USB Device and the GBIP-USB-HS shows up as an NI GPIB Interface. Both of these instruments are recognized in NI MAX as well but communication with the GBIP adapter (and connected instruments) fails and it cannot scan for instruments, and the self test fails with an unknown gpib hardware error (-37052). The VISA Interactive Control also shows neither device.
The ready light is on on the GPIB-USB adapter, and the 8451 flashes green as if nothing's wrong on its end. I have uninstalled all NI software and reinstalled it, and I run MAX as admin. Are there possibly some computer settings I have overlooked or need to change to open up communication? Any other ideas on why I can't communicate with the devices?
Thanks!
Trey
