Interface Troubleshooting
When the evaluation board is connected to the PC by a
USB cable and communicates with the interface on the
evaluation board a green check mark will appear next
to the USB Interface Status.
If there is a red X instead of the green check, 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 a red X, Close and restart the ISL9519
control software.
If you still get a red X, Open the Device Manager
(Control Panel/System/Device Manager) with the
ISL9519EVAL1Z 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 a red X, contact an Intersil Field
Application Engineer for assistance.
