autoread Available on some readers and sed
in conjunction with the property,
scanDuration.
• When enabled, the reader is in a
continuously listening mode in the
following way – the reader
gathers tag information for
scanDuration msecs, reports the
findings and loops again through
the same read and report
sequence.
•Ifautoread is set to false, then
the filters and connectors that
receive the events from the reader
adapter see no events, unless
external software initiates the tag
list request programmatically.
Also see “Additional Information for
Common Properties” on page 50.
Default value = false
(disabled)
Value = true (enabled)
communicationTimeout Indicates how long to wait for a
reader response before
retransmitting a read request.
Default value = 10,000
msecs
Using a higher value,
such as 20 seconds,
causes the adapter to
generate fewer
retransmissions, but
potentially detects
network problems less
rapidly.
scanDuration Indicates the antenna pulse duration
in milliseconds. The antenna pulse
duration is the time that the antenna
is powered and actively scanning for
RFID tags.
Default value = 500
msecs
For enabling antennae
and discriminating
between antennae
varied properties exist
that are specific to each
reader adapter.
Each adapter has a unique way of
enabling the various antennae, as
well as discriminating between the
multiple antennae of one reader.
