C0 RF controlled by host
C1 RF controlled by presence sensor on input0, the red/green pair
(factory default)
O0 RF off
O1 RF on
T1 Uniqueness timeout of two minutes
T2 Uniqueness timeout of 15 seconds
T3 Uniqueness timeout of 30 seconds
Fxxx RF output frequency, xxx = 000 to 118 hexadecimal offset in 250
kHz from 860 MHz. If an invalid frequency value is stored
(corrupted NVRAM), then xxx = “XXX” to indicate an error in
the frequency setting.
Rxx Tag decoder range (distance) for ATA tags, xx = 00 to 1F
hexadecimal range value
Gxx Tag decoder range (distance) for eGo and eGo Plus tags, xx = 00
to 1F hexadecimal range value
Axx RF power attenuation, where 00 is maximum output power and
0A is minimum output power (10dB less than maximum power).
Ixx IAG RF power attenuation, where 00 is maximum output power
and 0F is minimum output power (15 dB less than maximum
power)
For example, if factory default settings are assigned, the reader message is
RFST C1 O0 T1 Fxx R1F G1F A00 I04
which means that RF is enabled by presence sensor on input0, RF signal off, unique-
ness timeout of two minutes, RF output frequency has not been set, maximum RF out-
put range for ATA tags, maximum RF output range for eGo and eGo Plus tags, full RF
power, and IAG power set at 4 dB attenuation.
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
