for the registered Slave Reader/Writers.
If the Master Reader/Writer cannot establish communications with a registered Slave Reader/Writer (e.g., due to an
incorrect IP address or because the Slave Reader/Writer is not started), the ERROR indicator (red) on the Master
Reader/Writer will flash at 1-s intervals.
13. You can confirm when communications have been established with all of the Slave Reader/Writers
from the Multi-Reader/Writer Setting View of the Web browser operation window.

indicator on the Master Reader/Writer will remain lit green.
15. This concludes the procedure to set Field Extension Mode. You can now use READ DATA or WRITE
DATA queries from the host controller for the Master Reader/Writer to perform linked operation of
multiple Reader/Writers.
