Description of the configuration parameters
If several antennas look at a population of tags and it is immaterial which antenna detects any tag, the time for a
complete detection of the tag population can be reduced by activation of this configuration parameter: Tags which
had already been detected by one antenna are no longer detected by the following antennas in the multiplex list.
2.4.13.
“TransmitSelectIfNoFilterIsOn”
Characteristics:
available from firmware:
v1.45.00
Data type:
Bool (8-bit)
Unit:
–
Value range:
0; 255
Description:
At the start of an inventory the reader sets all tags that are within antenna range to a defined initial status, using
a defined “select filter” or a “select” command. The subsequent inventory then detects all tags that are in this
defined initial status. If no select filters were defined, this configuration parameter can be used to specify whether
or not before the inventory a select command should be sent to perform a global reset of all tags within the
antenna range.
2.4.14.
“NumberOfEPCWords”
Characteristics:
available from firmware:
v2.00.00
Data type:
Byte (8-bit)
Unit:
–
Value range:
0-31; 255
Description:
From firmware version v2.00.00, RRU4 RFID readers of the Kathrein reader system can read tags with an EPC length
of 0 to 31 words (0 to 496-bit EPCs). This parameter allows deactivation of the automatic detection of the EPC length,
thus forcing the reader to work with a fixed length.
2.4.15.
“UseBlockWrite”
Characteristics:
available from firmware:
v2.00.00
Data type:
Bool (8-bit)
Unit:
–
Value range:
0; 255
Description:
If this configuration parameter is activated, the reader uses the command “BlockWrite” for writing data to a tag.
This means that more than 16 bits (one word) can be written to a tag with just a single command and thus save
“write time”.
Note
Not all tags support the command “BlockWrite”. See also the “EPCglobal Class 1 Generation 2 UHF RFID”
((E)) specification V1.2.0 section 6.3.2.11.3.7 (page 74).
