The following equations can be used to calculate transmit center frequency
in LP and DTS modes,remembering the exceptions listed above for the
Anatel versions.
Fc = 902.271 + chan *.3007MHz(LP)
Fc = 902.272 + chan*.7517MHz(DTS)
All modules in a network must be in the same mode (LP or DTS) and must
have the same transmit and receive channels programmed in order to
communicate properly.
Power Mode
The transmission and reception modes of the module are determined by
the settings of the regPWRMODE register. It is important to note that a
module configured to operate in LP mode cannot “hear” another module
transmitting in DTS mode, or vice versa. However, a module configured
to operate in any of the three DTS modes can “hear” any other module
transmitting in any of the DTS modes (provided that they are within range
of one another). LP mode operation must be low power. Additional power
settings are included for cases where the antenna circuit is very lossy, such
as a PCB loop antenna.
