MHX-920 Operating Manual: Appendix F. Hopping Patterns 55
F. Hopping Patterns
This Appendix provides a guide for selecting appropriate hopping patterns (S106,S206). There
are 64 hopping patterns: The first 62 come pre-programmed from the factory as per the table
below. There are 31 patterns in Group A and 31 in Group B. When deploying a network, it is
recommended that you use choose hopping patterns all belonging to the same group. Patterns
have been designed to notch out certain segments of the ISM band.

Patterns 58 to 63 -may be manually entered or edited by entering AT&H at the Command Line, and following the
prompts. Each pattern must use a channel only once, and must consist of exactly 50 channels. There are 127
channels available ranging from Channel 1 at 902.4 MHz up to Channel 127 at 927.6 MHz.
