Yes, the new Logger function can also be used with all NanoLockits that were sold before the release of the Logger.
Since firmware version v6.30 the logging function is integral part of the NanoLockit firmware and usable on all generations of Nanos down to the first unit built. Just make sure to update your Nano to the latest version via the LockitToolbox and you are good to go.
What you will need in addition is the Logger software to extract the log file from the Nano and the Premiere panel.
