7–108
T2
Uniqueness timeout of 15 seconds (
#442
)
T3
Uniqueness timeout of 30 seconds (
#443
)
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 (
#647xxx
or
#642NN
).
Rxx
Tag decoder range (distance) for ATA tags, xx = 00 to 1F hexadecimal range value
(
#643NN
, 1F = Max RNG)
Gxx
Tag decoder range (distance) for eGo and eGo Plus tags, xx = 00 to 1F hexadecimal
range value (
#645NN
, 1F = Max RNG)
Axx
RF power attenuation, where 00 is maximum output power and 0A is minimum output
power (10dB less than maximum power)
(#644NN
).
Ixx
IAG RF power attenuation, where 00 is maximum output power and 0F is minimum
output power (15 dB less than maximum power) (
#646NN
)
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, uniqueness timeout of two
minutes, RF output frequency has not been set, maximum RF output 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
Select RF Control Algorithm). If presence without tag reports is enabled (
#6901
Enable Presence without Tag Reports
), the reader transmits a report if a presence is detected
without the subsequent acquisition of a valid tag.
Note:
RF timeout values vary depending on the operative tag read mode and the type of tag in the
read field. All times are approximate.
Reader message:
PRST P<0 to 1> D0 A<0 to 2> T<0 to F> I<0 to 1>
where
P0
Presence without tag reports disabled (factory default) (
#6900
)
P1
Presence without tag reports enabled
(#6901)
D0
Minimum presence true period of 0 ms (fixed)
A0
(#692N)
RF off on timeout only
(#6920)
A1
(#692N)
RF off on timeout or tag
(#6921)
