Network Settings
Static network settings are ignored when in DHCP mode, and DHCP-related settings are
ignored when in static IP mode. Please note that your network needs to have properly
configured DNS servers, to connect to the Reader through its hostname. Usually when
using DHCP, the DHCP server will add the hostname to the DNS server's database.
Setting Description
Tag Reader
Protocol Settings
• Maximum tag read rate - Performance is optimized for maximizing the speed
of tag to/from reader communications, which results in more tags being read
faster. OR
• Maximum receive sensitivity - Performance is optimized for reading weaker,
harder to read tags.
Note: NOTE: Mostly applicable to using Battery Assisted Passive Tags. Most
Passive Tag applications are range limited by the power output from the
antenna, not the reader's ability to "hear" a tag's response.
• Customize - Set low level Gen2 parameters related to tag to reader
communication speed vs sensitivity. See the MercuryAPI Programmers Guide |
Performance Tuning
section for more details on these settings.
Tag Population
Size Settings
• Automatically adjust settings as tag population changes - Reader
dynamically adjusts optimization setting depending on the tag population it
detects in the field.
• Adjust settings for an approximate population of X - If the tag population
size is relatively well known and consistent, performance can be increased by
optimizing for that size. In this case enter the approximate population size for
increased performance.
• Customize - Set low level Gen2 parameters related to tag population size. See
the MercuryAPI Programmers Guide | Performance Tuning section for more
details on these settings.
Tag Repeat Rate
• Tags repeat as often as possible - Tags will re-respond to an on-going
inventory operation as quickly as possible.
• Tags wait ~0.5 seconds to repeat - Tags will sleep for their "flag persistence"
period, typically 0.5 to 2.0 seconds. This is preferred when trying to inventory
large populations of tags as it allows "weaker" tags a chance to respond.
• Customize - Set low level Gen2 parameters related to tag response rate and
session usage. See the MercuryAPI Programmers Guide | Performance
Tuning
section for more details on these settings.
