CHAPTER 5 READER-HOST PROTOCOL
G
ET PERSISTTIME
S
ET PERSISTTIME
The PersistTime specifies the length of time a tag’s data will remain in the
reader’s internal list of active tags.
• Persist times are specified in seconds.
• The default setting is 10 seconds.
• Setting the persist time to a positive number (1-n) will establish a persist time
of the desired number of seconds
• A zero persist time (0) will guarantee that tags are not stored in the tag list.
However issuing a get taglist command in interactive mode will return any
tags immediately found even though they won’t be stored in the taglist.
• Setting the persist time to –1 will cause the history to build indefinitely until a
get taglist command is issued; at this point the tag list is returned, and then
immediately cleared.
The maximum number of tags that can be stored in the tag list is 1000. Once this
tag limit is reached, error messages will be reported to the serial console, and no
new tags will be added to the list until room is available.
NOTE: Changes made with this command will take effect immediately.
