Errata

"OK>" output from trigger action not preceded by EVT:TRIGGERACTION"

When a trigger action macro is specified, all output that results from the execution of the macro should be preceded by "EVT:TRIGGERACTION ". Prior to this release, none of the macro output was prefaced with that message. Now, only the "OK>" prompt that results from the macro execution is missing the event prefix.

Work-around: none.

Trigger action command executed inconsistently

When the "action" field of a trigger is modified, and the trigger fires, the reader will sometimes appear to execute the old action instead of the new action.

Work-around: Create a trigger once and don’t modify it.

FCC readers hop during long write operations.

The maximum channel dwell time for FCC readers is 400 milliseconds. When writing large amounts of user memory to Gen2 tags, a tag access operation can be interrupted by a frequency hop. In that case, the write operation fails. It is possible to specify writes that can never succeed because they exceed the 400 millisecond dwell time.

Work-around: Break up the write data in to smaller chunks and write the data one chunk at a time.
