X0
Software Flow Control disabled
X1
Software flow control enabled (factory default)
S0
start of message character is #
For example, if factory default settings are assigned, the reader message is:
ECPS P0 TFE X1 S0
which means basic protocol selected, an ECP timeout of 254 (12,700 ms or 12.7 sec),
software flow control enabled, and start of message character is
#.
527 Display RF Status
#
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
(not applicable to the MPRX). RF always is
controlled by Sense 0 and Sense 1 when reader is in MPRX mode. Sense 0 enables RF
on antenna ports 0 and 1, and Sense 1 enables RF on antenna ports 2 and 3. Refer to
“MUX Operational Modes” on page 5–85
. Command
#527
also displays the current
RF status and the uniqueness timeout.
Note:
If you enter RF settings using Command
#642NN
, the display command for RF output
frequency, F is
“Fxx”
and indicates use of the backward-compatible frequency entry method.
Reader response:
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 input 0, 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 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
