DIN-Rail Mounting The aluminum DIN-Rail attachment plate should already be fixed to the back panel of EDS when you take it out of the box. If you need to reattach the DIN-Rail attachment plate to EDS, 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...
Wall Mounting (OPTIONAL) For some applications, you will find it convenient to mount MOXA EtherDevice Switch on the wall, as illustrated below. STEP 1: Remove the aluminum DIN-Rail attachment plate from MOXA EtherDevice Switch’s rear panel, and then attach the wall mount plates, as shown in the diagram below. plate ⇒...
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.
Grounding MOXA 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. This product is intended to be mounted to a well-grounded mounting surface, such as a metal ATTENTION panel.
Wiring the Redundant Power Inputs The top two contacts and the bottom two contacts of the 6-contact terminal block connector on EDS’s top panel are used for EDS’s two DC inputs. Top and front views of one of the terminal block connectors are shown here.
Communication Connections EDS-308 models have 6, 7, or 8 10/100BaseT(X) Ethernet ports, and 2, 1, or 0 (zero) 100BaseFX (SC-type connector) fiber ports. EDS-305 models have 4 or 5 10/100BaseT(X) Ethernet ports, and 1 or 0 (zero) 100 BaseFX (SC-type connector) fiber ports. 10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) ports located on EDS’s front panel are used to connect to Ethernet-enabled devices.
100BaseFX Ethernet Port Connection The concept behind the SC 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-308 Series DIP Switches EDS-305 Series DIP Switches 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. The relay will form a closed circuit and the Fault LED will never light up.
Auto MDI/MDI-X Connection The Auto MDI/MDI-X function allows users to connect MOXA EtherDevice Switch’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 EDS to Ethernet devices.
automatically keeps up with new node locations. An address-aging algorithm causes the least-used addresses to be deleted in favor of newer, more frequently used addresses. To reset the address buffer, power down the unit and then power it back up. Auto-Negotiation and Speed Sensing All of MOXA EtherDevice Switch’s RJ45 Ethernet ports independently support auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with operation according to the IEEE 802.3u...
