641 Select RF-by-Input Control (Factory Default)
Command #641 configures the reader for RF-by-input control. The reader automati-
cally turns on RF when it detects a presence through sense0. The reader turns off RF
according to the selected RF control algorithm (#692N Select RF Control Algorithm).

643NN Select ATA Operating Range (Distance)
Command #643NN selects the read range for ATA tags where NN is a hexadecimal
value from 00 to 1F; the range increases with increasing NN value. The range can be
adjusted for 32 discrete values where 00 is the shortest range and 1F is the longest
range. The default range value is 1F.

644NN Set RF Attenuation
Command #644NN sets the attenuation control for the output RF power where NN is
a hexidecimal value from 09 to 0F. Settings for attenuation are 1.0 dB increments over
a range of 6 dB of attenuation from the maximum power setting of 24 dBm at 0-dB
attenuation to a minimum power level of 18 dBm.
