IP : Enter the IP or hostname of the FR900
Note: You can find out the name and the IP address by using the BB Shell show network
summary command. The show network summary command provides the dynamic values that are
returned by DHCP or LLA if the current configuration is dynamic. The local hostname resolution feature
(mDNS) gives the Reader a local hostname in addition to an IP address as its network identity. On an
isolated network that lacks DNS service but that has mDNS enabled, a Reader with hostname FR900-
A1-B2-C3, for example, can be reached using FR900-A1-B2-C3.local.
Reader Mode : Specifies the rules to use for communication between the Reader and the tag.
-
Default : Mode 1
-
Fastest
: Mode 3
Session : To control when and how often the Reader reads a tag. Each tag contains a flag that is flipped
from A to B or from B to A when it is read. The Session value controls how long the flag retains its
value before reverting back to the original tag value. Search Mode controls which flag values the
Reader reads and, in some cases, what happens to the flag value after the tag is read.
When you set Session to Dual Target, the Reader reads all the tags that have A flags.
Then, after reading the tags, the Reader flips each tag to B. When there are no more A tags to read, the
Reader reads all the B tags, flipping each one to A after it has been read. It continues this process
back and forth from A to B and back to A. Session 1 ensures that there is a persistence period that
prevents tags from reverting before they have all been read.
-
Session 0 (Auto Toggle On) : Continue reading the same tag
-
Session 1 (Auto Toggle On) : The same tag is read every 0.5 ~ 1 second
-
Session 2 or 3 (Auto Toggle On) : The same tag reads only once
Population : 1 to 65535 can be set. Set to 100 if there are 100 tags in front of the antenna.
Rx Sensirivity : Max or -70 ~-30
Rx limit (RSSI) If set to -50db, RSSI below -50db will not be read.
Filter : If set to 1234, only EPCs starting with 1234 are read
Memory Bank : Reserved , EPC, TID, User (Usually use EPC)
Bit Pointer : Memory offset (bit) at filter, 32bit offser for EPC, 0bit for rest
Length : Double the length of the filter text
