    Hi,
    Sorry your post has been missed for a few days.

    I'm not clear with your question. Are you saying that you went through the unlock sequence. As the result of the unlock sequence you lost the MAC address and you are asking how to re-program the MAC address?

    You can select the MAC Address Mode and give your MAC address. If you are using the LaunchPad then there is a sticker in the backside of the LP board that shows the MAC address. You just program that MAC address again.
