Reader response:
RFST C<0 to 1> O<0 to 1> T1 Fx Rxx Gxx Axx
where
C0
RF controlled by host
C1
RF controlled by presence sensor on input0, the red/green pair
(factory default)
(factory default)
O0
RF off
O1
RF on
T1
Uniqueness timeout of two minutes (fixed)
Fxx
RF output frequency, xx = 00 to 34 hexadecimal offset in 500
kHz from 902 MHz. If an invalid frequency value is stored
(corrupted NVRAM), then xx = “XX” to indicate an error in the
frequency setting.

(corrupted NVRAM), then xx = “XX” to indicate an error in the
frequency setting.
Rxx
Tag decoder range (distance) for ATA tags, xx = 00 to 1F
hexadecimal range value
hexadecimal range value
Gxx**
Tag decoder range (distance) for Intellitag tags, xx = 00 to 1F
hexadecimal range value
hexadecimal range value
Axx**
RF power attenuation, where 00 is maximum output power and
0A is minimum output power (10dB less than maximum power).
0A is minimum output power (10dB less than maximum power).
For example, if factory default settings are assigned, the reader message is:
RFST C1 O0 T1 F1A R1F G1F A00
which means that RF is enabled by presence sensor on input0, RF signal off, and
uniqueness timeout of two minutes, RF output frequency of 915 MHz, maximum RF
output range for ATA tags, maximum RF output range for Intellitag tags, and full RF
power.
uniqueness timeout of two minutes, RF output frequency of 915 MHz, maximum RF
output range for ATA tags, maximum RF output range for Intellitag tags, and full RF
power.
529 Display Presence Input Status
Command #529 displays the parameters associated with presence detection and RF
control. The reader’s message indicates if presence without tag reports are enabled/
disabled (#690N Select Presence without Tag Report Option), if input inversion is
enabled/disabled (#694N Select Input Inversion Option), and the minimum presence
true period (always true). The reader’s message also reports the selected RF timeout
(#693N Select RF Timeout Period) and the selected means of RF-off control (#692N
control. The reader’s message indicates if presence without tag reports are enabled/
disabled (#690N Select Presence without Tag Report Option), if input inversion is
enabled/disabled (#694N Select Input Inversion Option), and the minimum presence
true period (always true). The reader’s message also reports the selected RF timeout
(#693N Select RF Timeout Period) and the selected means of RF-off control (#692N
