TransCore Proprietary 7–18
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 SeGo protocol 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).
I04 Fixed
For example, if factory default settings are assigned, the reader message is
RFST C1 O0 T1 Fxxx 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 Report Option), 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 response:

P0
Presence without tag reports disabled (factory default)
P1 Presence without tag reports enabled
