Description of the configuration parameters
2.5.3.
“ObservedTimeoutCnt”
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 no longer detected, which then
triggers the generation of a “going” message which is sent to the higher level.
2.6.
The configuration group “Host communication” (“HostComm”)
2.6.1.
“ExtendedResultFlag”
Characteristics:
available from firmware:
v1.30.00
Data type:
Byte (8-bit)
Unit:
–
Value range:
0-15
Description:
This configuration parameter allows specification of which additional information on a tag should be sent when tag
data are sent to the higher level. Every bit of the lower four bits that is set to “1” in this configuration parameter
causes the sending of certain additional information:
Bit 0: Sending the antenna information (the antenna which detected the tag)
Bit 1: Sending the RSSI value (field strength information of the tag response)
Bit 2: Sending the time stamp (the time when the tag was detected)
Bit 3: Sending the protocol control word of the tag (PC, [XPC_W1, [XPC_W2]]; see also the “EPCglobal Class 1
Generation 2 UHF RFID” specification V1.2.0 section 6.3.2.1.2 (page 38).)
2.6.2.
“AntennaIndependentOperation”
Characteristics:
available from firmware:
v1.30.00
Data type:
Bool (8-bit)
Unit:
–
Value range:
0; 255
Description:
This configuration parameter allows differentiation between “antenna-dependent” (configuration parameter
deactivated) and “antenna-independent” (configuration parameter activated) operation of the reader.
This configuration parameter is relevant to all asynchronous protocol commands (“ASync...”) and to the
command “SyncBulkGetEPCs”. In the case of the specified protocol commands the reader compares a tag
which it has detected during an inventory with the tags listed on an internal list.
