Used to set the alarm auto rebroadcast period. Valid values are 0
(disabled), 1
– 3600 seconds. Default is 3600 seconds.
This specifies how long to wait before rebroadcasting a persistent
alarm. For example, if Alarm Unique Delay = 60 and the capacitance
low alarm is triggered, the IS1001 reader will wait 60 seconds before
resending the alarm. If the alarm condition clears and then
reappears, the new alarm will be sent without delay.
Note:
The Virtual Tag Test Failed alarm and the Antenna Over
Current alarm are the exceptions and will not be rebroadcast. These
alarms are triggered only when the condition takes effect.

ADT

Set Dynamic Tuning {1} On, {0} Off
Used to set antenna dynamic tuning to either On or Off. Default is
On.
Dynamic Tuning automatically adjusts the tuning capacitance
settings to achieve the set target phase value.
AFT
Perform Antenna Full Tune
Used to initiate the full auto-tune process for the antenna attached
to the IS1001 reader. It is used to determine the optimum tuning
parameters. During this process the IS1001 reader goes through
every possible electronically-switched capacitor setting combination
to find the tuning target phase, the tuning phase deviation threshold,
and the initial tuning capacitance setting based on the properties of
your system and its environment.
Note:
The initial tuning capacitance setting will be used as the
origination setting every time the reader is powered up or reset.
The full auto-tune process will typically take about 40 seconds to
complete.
Results of the entire process are sent to all available ports for review
and analysis. This information is useful for determining the proper
tuning capacitance adjustments at the antenna, if needed.
The
Esc
key can be used to cancel the process.
Note:
The full auto-tune process should be performed during initial
system installation; after IS1001 reader
’s parameters are reset to
default values and anytime the antenna has been repaired,
replaced, or moved to a new location, as this may change the
optimal settings for the antenna.
ATC
{0-1023}
Set Antenna Tuning Capacitors
Used to set the specific antenna tuning capacitance setting. Valid
values are 0
– 1023.
Note:
This value is also controlled by the dynamic tuning
mechanism. You should turn off dynamic tuning while manually
adjusting the tuning capacitors or the settings will be overridden by
the auto-tuning mechanism. Changing capacitors manually should
