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.
