Read “Performance” is slow

Performance, as it relates to tag reading, is very usecase dependent. Typically, it comes down to whether you are trying to read lots of tags once or a few tags repeatedly. If the reader settings aren?t correct for your usecase the performance will appear poor.

• Use the Performance Tuning Options to modify the settings for your usecase.

• See the MercuryAPI Programmer’s Guide | Performance Tuning section for details about Gen2 settings and try using the Advanced Performance Tuning options directly.

Errors after a Firmware Upgrade

• If the upgrade was of the M6 from v4.7 to a newer version make sure to read the Release Notes of the newer version. There are special steps that must be taken to make that upgrade.

• Try reinstalling the firmware and restarting URA.
