Connecting the USB Cable
The USB(A)-USB(B) cable is required only to reprogram the FPGA using the JTAG port when programming has been lost or damaged. Contact
Technical Support for all FPGA programming issues.
Connect one end to a Windows PC USB port and the other end to the USB JTAG port on the OPAL-RT simulator, then follow the technical support
representative’s instructions to reprogram the FPGA.
