@section Writing EEPROM and calibration
By default @sc{wrpc} starts in @sc{wr} Slave mode and uses the default calibration
values for Axcen AXGE-3454-0531 @sc{sfp}. This might be fine for running @sc{wrpc}
for the first time and synchronizing it to another @sc{spec} running the same
firmware. It is however recommended to perform few additional steps through the
@sc{wrpc} shell.
You should perform few configuration steps through the @sc{wrpc} shell before
you start testing and using the firmware.
@b{Note:} the examples below describe only a subset of @sc{wrpc} Shell commands
required to make a basic configuration and calibration. A full description of
