Interface Troubleshooting
When the evaluation board is connected to the PC by a USB
cable and the software is running, the software assigns a VISA
resource name.
If this window is blank, it indicates a problem with
communication between the PC and the micro controller on
the evaluation board. Check and correct the connection of the
USB cable to your PC and the evaluation board. Click on the
“RESET INTERFACE” button.
If you still get no VISA resource name, Close and restart the
ISL88731(C) control software.
If you still get no VISA resource name, Open the Device
Manager (Control Panel/System/Device Manager) with the
ISL88731(C)EVAL2Z evaluation board connected to your USB
port. You should see a device named “NI-VISA USB Device”. If it
is not in the list of devices, the driver may not be correctly
installed. Run the New Hardware wizard.
If you still get no VISA resource name, contact your Intersil
Field Application Engineer for assistance.
