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