Wall Mounting (optional) For some applications, you will find it convenient to mount the EDS on the wall, as illustrated below. STEP 1: Remove the aluminum DIN-rail attachment plate from the EDS’s rear panel, and then attach the wall mount plates, as shown in the diagram below. top plate ⇒ bottom plate STEP 2: 6.0 mm Mounting the EDS on the wall requires 4 screws. Use the switch, with wall mount plates attached, as a guide to mark the correct locations of the 4 screws.
Wiring Requirements WARNING Do not disconnect modules or wires unless the power supply has been switched off or the area is known to be non-hazardous. The devices may only be connected to the supply voltage shown on the type plate. The devices are designed for operation with a Safety Extra-Low Voltage. Thus, they may only be connected to the supply voltage connections and to the signal contact with the Safety Extra-Low Voltages (SELV) in compliance with IEC950/ EN60950/ VDE0805.
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. Wiring the Alarm Contact The Alarm Contact consists of the two middle contacts of the terminal block on EDS’s top panel.
ATTENTION Before connecting the EDS to the DC power inputs, make sure the DC power source voltage is stable. Communication Connections EDS-308 models have 6, 7, or 8 10/100BaseT(X) Ethernet ports, and 2, 1, or 0 (zero) 100BaseFX (SC/ST-type connector) fiber ports. EDS-305 models have 4 or 5 10/100BaseT(X) Ethernet ports, and 1 or 0 (zero) 100 BaseFX (SC/ST-type connector) fiber ports.
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.
one of the ports for which the corresponding PORT ALARM DIP Switch is set to ON is not properly connected. If neither of these two conditions occurs, the Fault circuit will be closed. DIP Switch Settings EDS-308 Series DIP Switches ON 1 2 EDS-305 Series DIP Switches DIP 3 4 5 6 7 ON 1 8 2 DIP 3 4 5 ON: Enables the corresponding PORT Alarm. If the port’s link fails, the relay will form an open circuit and the fault LED will light up. Off: Disables the corresponding PORT Alarm.
Auto MDI/MDI-X Connection The Auto MDI/MDI-X function allows users to connect the EDS’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 to Ethernet devices. Fiber Ports The EDS’s fiber switched ports operate at a fixed 100 Mbps speed and full-duplex mode to provide the best performance.
The EDS operates in the store-and-forward switching mode, which eliminates bad packets and enables peak performance to be achieved when there is heavy traffic on the network. Switching and Address Learning The EDS has an address table that can hold up to 1K node addresses, which makes it suitable for use with large networks. The address tables are self-learning, so that as nodes are added or removed, or moved from one segment to another, the EDS automatically keeps up with new node locations.
