Description of the configuration parameters
2.4.16.
“DisableReceivingNXPReadProtectedTags”
Characteristics:
available from firmware:
v2.01.00
Data type:
Bool (8-bit)
Unit:
–
Value range:
0; 255
Description:
If a tag from the company NXP was protected by “ReadProtect”, at inventory it would no longer communicate
its EPC or a valid checksum. The data content of the EPC and the checksum is zero. To allow such tags to be
detected, the reader allows tags for which the EPC and checksum are zero to pass. Since such tags are no
longer secured with a valid checksum, it can happen very occasionally that the reader detects such a tag where
none exists. In order to prevent this, the reception of “ReadProtected” tags can be suppressed by activation of this
configuration parameter.

The configuration group “ObservedList”
2.5.1.
“GlimpsedTimeoutCnt”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
–
Value range:
0-255
Description:
This configuration parameter applies only to asynchronous protocol commands (“ASync...”). For the duration
of an asynchronous command, the reader compiles a list of all the tags found within the antenna range. If a tag
is present in the antenna range for multiple inventories, a “coming” message is generated for that tag and the
message is sent to the higher level. If a tag is no longer detected during multiple inventories, a “going” message is
generated and sent.
Once the “going” message has been generated for a tag, this configuration parameter specifies the number of
inventories where the tag is not detected, which then triggers deletion of this tag from the internal administration list.
This parameter should not be changed. It has no influence over the generation of a “coming” or “going” message.
Kathrein reserves the right to remove this parameter from firmware versions at a future point in time.
2.5.2.
“ObservedThresholdCnt”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
–
Value range:
0-255
Description:
This configuration parameter applies only to asynchronous protocol commands (“ASync...”). For the duration
of an asynchronous command, the reader compiles a list of all the tags found within the antenna range. If a tag
is present in the antenna range for multiple inventories, a “coming” message is generated for that tag and the
message is sent to the higher level. If a tag is no longer detected during multiple inventories, a “going” message is
generated and sent.
This configuration parameter specifies the number of inventories where the tag is detected, which then triggers the
generation of a “coming” message which is sent to the higher level.
