UHF RFID System V780-series Reader/Writer User’s Manual (Z389)
The RF communications timeout time lets you specify an upper limit to the time required to process
single-access or multiaccess communications. You can use this to provide leeway for details in
detecting RF Tags in the communications range or to adjust the timing of when responses are
returned.
The RF communications timeout time is measured from when the Reader/Writer starts executing a
communications command until an RF Tag is detected. If an RF Tag is not detected before the time-
out time expires, an RF Tag missing error response is returned. If an RF Tag has already been
detected when the timeout time expires, communications with that RF Tag are completed. (Commu-
nications after RF Tag detection will not be aborted for a timeout.)
The write verify setting can be used to automatically check the accuracy of written data for any com-
munications command that writes data to an RF Tag.
When a communications command is executed, communications diagnostics are performed to diag-
nose how much leeway there is in RF communications.
Monitoring status during operation helps create a more stable Reader/Writer and RF Tag installa-
tion.
*1. If you enable communications diagnostics, the communications time will be longer than when they are dis-
abled.
