Grounding the EtherDevice Switch Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices. ATTENTION This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.
ATTENTION Before connecting the EDS to the DC power inputs, make sure the 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.
RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring 100BaseFX Ethernet Port Connection Remember to connect the Tx (transmit) port of device I to the Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx (transmit) port of device II.
ATTENTION This is a Class 1 Laser/LED product. To avoid causing serious damage to your eyes, do not stare directly into the Laser Beam. Turbo Ring DIP Switch Settings EDS-505A/508A series are plug-and-play managed redundant Ethernet switches. The proprietary Turbo Ring protocol was developed by Moxa to provide better network reliability and faster recovery time.
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.
