2.6 Site-Calibrated Example Data
The graph (right) demonstrates an electric fence being
monitored. A high flat line describes the electric fence
as on and running uninterrupted at full strength.
A steep decline and low flat line shows when the
electricity was off. The sporadic line movement shows
that electricity is running but it is being interrupted by a
trip, requiring attention.
if(decoded.fence_signal > 2000) {
decoded.fence_on = “Fence on”;
} else{
decoded.fence_on = “Fence off”;
}

decoded.rssi = bytes[byte++] *

Payload Decoder Calibration - Midway Value Location
RF Intensity As a Relative Metric - Site-Calibrated
2.5 Site-Specific Calibration
Upon installation, the baseline RF intensity of an
operational fence should be measured using the
command as defined in 3.5.1 in this manual. This status
will be a relative metric of RF intensity, unique to the site.
The RF intensity of an unpowered and tripped fence
should then be measured using the same procedure.
These values should be inputted into the payload decoder
to define operational and non-operational states.
Input into the payload decoder the midway value
calulated from the recorded operational and non-
operational states. In this payload decoder example
2000 is the midway value.
