Safari Network User Guide
NCU and SCU Radio Frequencies
NCUs and SCUs must have a radio carrier frequency
assigned to each. The RUs automatically set themselves to
the frequency of the NCU, or SCU within closest range.
In addition to the Unit ID for the SCU, there is an
associated Parent ID. This ID simply refers to the ID that
the SR-7100 SCU locks to on power up, and is set
automatically.
See Appendix B, Radio Frequencies, for channel, frequency
and throughput rates. Figure 2-2 illustrates the Frequency,
Unit ID, and Parent ID affiliation.
