the directed messages, when otherwise the whole network would have had to be run at the lower
data rate. Note that broadcast or multicast data must always be transmitted at the lowest rate.
We recommend keeping adaptive modulation set for most installations.
Security
Setting the security mode to EAP or PSK will enable device authentication. When enabled, the
remotes will authenticate with the AP (PSK) or a backend RADIUS server (EAP) before they are
allowed to pass data on the network. The authentication protocol is compliant with IEEE 802.1X.
If device authentication is enabled, over the air data encryption can also be enabled. This ensures
all over the air traffic is protected. When encryption is enabled, the device must occasionally ro-
tate the encryption keys. This rotation is logged in the event log with event type nx_auth. These
events can be suppressed in the event log configuration to prevent them from filling the event
log. See the MCR Technical Manual for instruction on controlling the event log.
