Converter 6 {FAILED because of an invalid response/FAILED
because it did not respond/FAILED because it's
incompatible with the backup/FAILED because it's RF is
turned off/was successfully learned/was not selected}

because it did not respond/FAILED because it's
incompatible with the backup/FAILED because it's RF is
turned off/was successfully learned/was not selected}

C.22 Read DAC Value by Index (All)
This command is used to display the contents of the calibration table (DAC value) for the given
Frequency Index (ff) and the given Attenuation Index (aa). The command is as follows:
@01/RDATTENff aa
Performance specifications guaranteed at nominal levels only.
Note: Parameters are not actual values for frequency and attenuation but the actual index into
the various arrays that make up the power calibration table: The valid ranges for these values are
dependant on device type and configuration.
If successful, the converter will return the following string:
Cal Data = dddd:
{dddd is the DAC value}
{End of transmission}
C.23 Write DAC Value by Index (All)
This command is used to set the contents of the calibration table (DAC value) for the given
Frequency Index (ff) and the given Attenuation Index (aa) to the given value (vvvv). The
command is as follows:
@01/WRATTENff aa vvvv
