Reader/Writer will flash at 1-s intervals.

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.

The RUN indicator will light yellow on Reader/Writers that are operating as Slave Reader/Writers. The
indicator on the Master Reader/Writer will remain lit green.
