Licensing

Clients who purchased the LBX400 prior to the introduction of the new License Packs will receive a complimentary Legacy license equivalent to the technical specifications of the unit at the time it was purchased. You need a Legacy license if you are upgrading from a firmware version earlier than 4.0.1.
