Free Download

Download the full version of LonScanner FX (54.3 MB self-extracting archive)
For installation instructions, see the LonScanner FX User's Guide. After installation, you can order an activation key to unlock all the features, or you can run the software in Demonstration mode. (In this mode, the LonScanner software discards every third packet, operates for only 10 minutes at a time, doesn't save packet logs, and displays only 20 packets from a packet log.)

Order an Activation Key or the New Five-Pack
To remove Demonstration mode limitations, order an activation key. You can order an activation key for a single user, or you can order the new low-cost five-pack of activation keys for five users. Each user can activate a second copy of LonScanner. See the LonScanner FX User's Guide for instructions.
