The RA setting
The RA setting controls power output. Higher values yield lower output powers. The command
RA for output can be set from 8-19 on the TR-100. Higher RA setting, for example RA19,
means lower output power. Lower RA setting, for example RA8, means higher output power.
In normal, unlicensed operation, the RA value should not be set below its factory default value.
The default/minimum value is reported with the “RA” command after a reader start up.
As Thinkify continues to improve noise and efficiency in the TR-100, exact measurements of
output power are somewhat open to small changes as we work on the reader. However, the
reader will output about 17 dBm at the setting RA10.
