This device can be configured to either permit or prohibit known encrypted traffic on its RF link. It is up to the user to decide which is appropriate based on how it will be used and the license under which it will be operated. These rules vary by country, frequency, and intended use. You are encouraged to read and understand these rules before going further.

Setup your node name and password as instructed at the top of this page
After you Save Changes allow your node to reboot
Return to the Node Status page and navigate to Setup > Administration
Obtain the blockknownencryption package from the BBHN website OR refresh the Package list (node must be connected to the internet)
Install the blockknownencryption package by uploading it or choosing it from the package drop-down list
Wait until the package installs and then reboot your node
