The fault circuit will open if: 1. A relay warning event is triggered, OR 2. The EDS-505A/508A is the Master of this Turbo Ring, and the Turbo Ring is broken, OR 3. Start-up failure. If none of these three conditions is met, the fault circuit will remain closed.
DC power source voltage is stable. Wiring the Digital Inputs The EDS-505A/508A unit has two sets of digital inputs, DI 1 and DI 2. Each DI consists of two contacts of the 6-pin terminal block connector on the EDS’s top panel. The remaining contacts are used for the EDS’s two DC inputs.

There are 4 Hardware DIP Switches for Turbo Ring on the top panel of EDS-505A/508A that can help setup the Turbo Ring easily within seconds. If you do not want to use a hardware DIP switch to setup the Turbo Ring, you can use a web browser, telnet, or console to disable this function.
NOTE You must enable the Turbo Ring function first before using the DIP switch to active the Master and Coupler functions. NOTE If you do not enable any of the EDS-505A/508A switches to be the Ring Master, the Turbo Ring protocol will automatically choose the EDS-505A/508A with the smallest MAC address range to be the Ring Master.
EDS-505A/508A’s 10/100BaseTX ports to any kind of Ethernet device, without needing to pay attention to the type of Ethernet cable being used for the connection. This means that you can use either a straight-through cable or cross-over cable to connect the EDS-505A/508A to Ethernet devices. Fiber Ports The fiber ports are factory-built as either multi-mode or single-mode SC/ST connectors.
