If the configuration is invalid for any reason (out of range or overlapping the first radio for
example), the primary node will automatically adjust to an appropriate frequency. If this occurs,
you may note that the current operating frequency for Radio 2 differs from its configuration.
Configure the Radio 2 frequency on the primary node via the Web UI:

Likewise, on the secondary node these variables exist but they are ignored as long as the node is
configured as a secondary node; the radio 2 frequencies are always controlled by the primary node.
4.6.7 Dynamic Channel Selection
The M4-2000 system features an advanced interference avoidance feature.
Known as Dynamic Channel Selection (DCS), this feature automatically hops the radio away from a
degraded frequency and selects the best available alternate frequency. Switching frequencies is
Known as Dynamic Channel Selection (DCS), this feature automatically hops the radio away from a
degraded frequency and selects the best available alternate frequency. Switching frequencies is
quick with very little or no packet loss over the link.
In the background, the system periodically scans across the channel plan to measure the signal level
In the background, the system periodically scans across the channel plan to measure the signal level
at each plan center frequency. The resultant accumulation of frequency observation data insures
selection of the optimal frequency when a channel hop is necessary.
The system can select different channels for uplink and downlink (i.e., F-TDD) to avoid localized
intereference on either side of the link.
To enable DCS, on the primary node Web UI select
