11.0 APPENDIX F – NX915 Module Frequencies
The NX915 module is a Frequency-Hopping Spread Spectrum (FHSS) radio that can be configured to
operate in a subset of all available frequencies for a particular modem mode (125kbps, 250kbps, 500kbps,
etc). The radio frequency will change at the "Dwell Time" rate, a default of 50ms.
The table below illustrates the discrete frequencies (or channels) that can be user configured. The selected
“hop-set” defines the specific channels of radio operation.
NOTE The module may be configured for by the factory to disallow operation in specific frequencies
to meet country specific regulatory requirements. These settings can NOT be changed or
modified by the user.
When specific hop-set can be user configured that defines a specific collection of radio operation.
The following table show the number of discrete frequencies (or channels) available for each modem type
based on the selected hop set
