ZMN2400 Frequency Selection
The ZMN2400 is not frequency agile during run-time, but it can select an unoccupied portion of the spectrum
at startup.
The ZMN-2400 series uses a set of channels as defined by the IEEE 802.15.4 / ZigBee standards which
span a range from 2405 to 2480 MHz with 5 MHz spacing between channels:
Center Frequency (MHz)

The channel mask is the name used to describe the list of frequency channels that a ZMN-2400 can use.
The default channel mask for client radios allows them to operate on any frequency from 2405 to 2475
(channel 2480 is reserved for manufacturing test purposes and therefore not included).
