Overview The EDS-205A/208A series of industrial Ethernet switches are entry-level industrial 5 and 8-port Ethernet switches that support IEEE 802.3, IEEE 802.3u, and IEEE 802.3x with 10/100M, full/half-duplex, and MDI/MDIX auto-sensing. The EDS-205A/208A series provides 12/24/48 VDC (9.6 to 60 VDC)/18 to 30 VAC redundant power inputs that can be connected simultaneously to a live AC/DC power source.

Mounting Dimensions EDS-205A EDS-208A Unit = mm (inch) -7-
DIN-Rail Mounting The aluminum DIN-rail attachment plate should already be fixed to the back panel of the EDS when you take it out of the box. If you need to reattach the DIN-rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the figures below. STEP 1: STEP 2: Insert the top of the DIN-Rail into The DIN-Rail attachment unit will the slot just below the stiff metal snap into place as shown below. spring.
STEP 3: Once the screws are fixed on the wall, insert the four screw heads through the large parts of the keyhole-shaped apertures, and then slide the EDS-205A/208A downwards, as indicated. Tighten the four screws for added stability. ATEX Information 1. 2. 3. 4. 5.
You should also pay attention to the following points: • • • • Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. NOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
Communication Connections The EDS-205A models have 4 or 5 10/100BaseT(X) Ethernet ports, and 1 or 0 (zero) 100 BaseFX multi/single-mode (SC/ST-type connector) fiber ports. The EDS-208A models have 6, 7 or 8 10/100BaseT(X) Ethernet ports, and 2, 1 or 0 (zero) 100 BaseFX multi/single-mode (SC/ST-type connector) fiber ports. 10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) ports located on the EDS’s front panel are used to connect to Ethernet-enabled devices.
100BaseFX Ethernet Port Connection The concept behind the SC/ST port and cable is quite straightforward. Suppose you are connecting devices I and II; contrary to electrical signals, optical signals do not require a circuit in order to transmit data. Consequently, one of the optical lines is used to transmit data from device I to device II, and the other optical line is used transmit data from device II to device I, for full-duplex transmission.
DIP Switch Settings EDS-205A/208A DIP Switches The default setting for each DIP Switch is OFF. The following table explains the effect of setting the DIP Switches to the ON positions.

Enables broadcast storm protection Disables broadcast storm protection ATTENTION To actively updated DIP switch settings, power off and then power on the EDS.
Switching, Filtering, and Forwarding Each time a packet arrives at one of the switched ports, a decision is made to either filter or forward the packet. Packets with source and destination addresses belonging to the same port segment will be filtered, constraining those packets to one port, and relieving the rest of the network from the need to process them.
