3.3 USB2ANY Interface

The on-board USB2ANY interface provides a bridge between TICS Pro software and the LMX1860-SEP device. When the on-board USB2ANY controller is first connected to a PC, or if the firmware revision for the controller does not match with the version used by TICS Pro, a firmware update to the controller is required.

  1. Connect the USB cable from the PC to the EVM. The USB interface provides the necessary power to enable the on-board USB2ANY controller.
  2. After Windows has set up a USB device, run TICS Pro in the PC.
  3. The next screen looks like the image below.
