^RW
Set RFID Read and Write Power Levels
Description Use this command to set the read and write power levels. This function is
useful when using different tag types or transponders that require different power levels to
obtain the best read and write abilities. If not enough power is applied, the transponder may
not have sufficient power for programming, and tag data will fail to encode. If too much power
is applied, the extra power may disable the tag may or cause data communication errors.

Important • This command is not supported by all printers or firmware. See Table 13
on page 287 for the list of printers and firmware with which you can use this command.
Parameters Details
r = read power
Sets the power level to match the desired output as calibrated in the factory.
Accepted Values:
H = high
M = medium
L = low
Default Value: H
w = write power
Note • This parameter is ignored on the R110Xi HF printer because
read and write powers cannot be specified separately. The printer uses
the value that you specified for read power for both the read and write
power settings.
Sets the power level to match the desired output as calibrated in the factory.
Accepted Values:
H = high
M = medium
L = low
Default Value: H
a = RFID antenna
selection
Note • This parameter applies only to the R110Xi HF printer.
Selects the antenna port that provides the best results for reading and writing.
Accepted Values:
1 = antenna port 1
2 = antenna port 2
Default Value: 1
