1.0 Introduction The DNT2400 series transceivers provide highly reliable wireless connectivity for point-to-point, point-to- multipoint and peer-to-peer applications. Frequency hopping spread spectrum (FHSS) technology en- sures maximum resistance to multipath fading and robustness in the presence of interfering signals, while operation in the 2.4 GHz ISM band allows license-free use world wide.
BaseSlotSize. Note that the base radio always reserves BaseSlotSize amount of time in each hop whether or not the base has user data to send. To help select appropriate parameter values, RFM provides the DNT Throughput Calculator utility pro- gram (DNTCalc.exe). This program is on the development kit CD. Enabling encryption (security) adds additional bytes to the data to be sent but the Calculator has a mode to take this into account.

The current range information is available in the CurrPropDelay parameter. LinkDropThreshold - this is the number of consecutive beacons missed by a remote that causes the remote to restart a link acquisition search. Please contact RFM technical support before making changes to the parameter.
SleepState is set to 0xC0. See Section 4.2.7 for additional information on the GPIO_SleepState parameter. If any difficulty is encountered in setting up the DNT2400DK development kit, contact RFM’s module technical support group. The phone number is +1.678.684.2000.
