One unit of link must be set to Master and the other one to Slave.

At the link initial phase the following parameters must be set to the same values on Master unit and Slave unit:

• Center frequency - it may be set by two ways:
  • Manually via Downlink center frequency and Uplink center frequency parameters. In this case link will be setup at once.
  • Automatically with "Automatic selection of center frequency" function. In this case frequency channel grids must be set on both units. At the initial phase Master unit will select its center frequency automatically, after that Slave unit will scan frequencies from its grids and link will be setup when Slave find the center frequency which Master operates on.

There are several approaches to define center frequencies:

• Frequency selection off - center frequency will be set manually.
• Instant DFS and radar detection center frequency will be set automatically according to frequency channel grids.
• Instant DFS

Link units may transmit on diffrerent center frequencies.

If automatic selection of center frequency is enabled you should set both uplink and downlink frequencies. If automatic selection is disabled ..................
