527 Display RF Status
Command !527 displays the current status of the RF module. The reader response
indicates whether RF is controlled externally by the host, set by command !640N RF
Control, or internally by input set by command
!641.
Command
!527
also displays the
current RF status and the uniqueness timeout.
Reader message:
RFST C<0 to 1> O<0 to 1> T<1 to 3> Fxxx Rxx Gxx Axx Ixx
where
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 Fixed
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 06 is minimum
output power (6 dB less than maximum power).
Ixx IAG RF power attenuation, where 00 is maximum output power and 06 is minimum
output power (6 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, uniqueness
timeout of two minutes, maximum range for ATA tags, maximum 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.
