NOTE If you do not enable any of the EDS-405A/408A switches to be
the Ring Master, the Turbo Ring protocol will automatically
choose the EDS-405A/408A with the smallest MAC address range
to be the Ring Master. If you accidentally enable more than one
EDS-405A/408A to be the Ring Master, these EDS-405A/408A
switches will auto-negotiate to determine which switch will be the
Ring Master.
NOTE To switch on the Master or Coupler functions of the DIP switch,
you need to enable the Turbo Ring Pole first.
