Appendix C: Receiver read range
settings
The Dart hub provides two control modes for Receiver read range: coarse mode and fine mode.
Coarse control mode is the default mode, which allows read range setting of a Receiver to be set
from 1 to 25, where 1 is the smallest read range setting and 25 is the largest read range setting. In
fine control mode, read range settings vary from 1 to 54, where 1 is the least sensitive (shortest
read range) and 54 is the most sensitive (longest read range) setting.
The following figures, one for coarse control mode, one for fine control mode, provide
guidelines on approximating read range settings based on Receiver antenna type in a line of
sight environment. This table is intended to be used a guideline. Actual ranges will vary based
on the presence of RF obstructions and adverse reflections. Range measurements are shown for
line of sight conditions. Ranges are typically decreased as the result of obstructions, whereas
adverse reflections can create areas of cancellation or enhancement of the signals which can be
unpredictable and are often non-intuitive. For these reasons, it is recommended to verify read
ranges experimentally for each application.
