This is a high quality, 6-foot-long USB cable with a 90-degree MicroUSB connector for accessing the USB port on the internal WaveShark Communicator board found inside our WaveShark Repeater product. This is an optional accessory that should only be required in the event that you accidentally disable both Wi-Fi and Remote Control on your WaveShark Repeater. You may also find this cable convenient if you'd like to access the internal WaveShark Communicator for any other reason.
