Mounting Dimensions (unit = mm)

The device has the following dimensions:

• Width: 74 mm
• Height: 100 mm
• Depth: 26.9 mm
• Terminal block width: 24.87 mm
• Mounting bracket depth: 16.28 mm
• Mounting bracket height: 12.21 mm

DIN-Rail Mounting

The plastic DIN-rail attachment plate is typically pre-fixed to the rear panel. If reattaching, ensure the DIN-rail kit is positioned towards the top.

Attaching to DIN Rail:

1. Insert the top of the DIN rail into the slot.
2. The unit will snap into place.

Removing from DIN Rail:

Method 1: Insert a flat-blade screwdriver horizontally into the DIN-rail kit under the EDS-205, pull upwards, and then release the unit towards you and away from the DIN rail.

Method 2:

1. Press the middle of the flat side of the mounting kit.
2. Pull the EDS-205 downwards.
3. Release it towards you and away from the DIN rail.

Wiring Requirements

Follow these guidelines for wiring:

• Use separate paths for power and device wiring. If paths must cross, ensure wires are perpendicular at the intersection.
• NOTE: Do not run signal/communications wiring and power wiring in the same conduit. Route wires with different signal characteristics separately to avoid interference.
• Bundle wires with similar electrical characteristics together.
• Keep input and output wiring separated.
• Label wiring to all devices when necessary.

Grounding the Moxa EtherDevice Switch

Grounding and wire routing help limit electromagnetic interference (EMI). Connect the ground wire from the rightmost contact of the 3-contact terminal block to a grounding surface before connecting devices.

Wiring the Power Inputs

The two left-most contacts of the 3-contact terminal block on the top panel are for DC input. Views of the terminal block connector are provided.

Steps:

1. Insert the negative/positive DC wires into the V-/V+ terminals.
2. Use a small flat-blade screwdriver to tighten the wire-clamp screws to secure the wires.
3. Insert the plastic terminal block connector prongs into the receptor on the EDS's top panel.

Communication Connections

The EDS-205 features five 10/100BaseT(X) Ethernet ports on the front panel for connecting to Ethernet-enabled devices.

10/100BaseT(X) Ethernet Port Connection

Pinouts for MDI (NIC-type) and MDI-X (HUB/Switch-type) ports are shown, along with wiring diagrams for straight-through and cross-over Ethernet cables.

Cable Wiring Diagrams

RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring

Connects a Switch Port to a NIC Port:

• Pin 1 (Tx+) to Pin 1 (Rx+)
• Pin 2 (Tx-) to Pin 2 (Rx-)
• Pin 3 (Rx+) to Pin 3 (Tx+)
• Pin 6 (Rx-) to Pin 6 (Tx-)

RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring

Connects a Switch Port to another Switch Port or NIC Port:

• Pin 1 (Tx+) to Pin 3 (Rx+)
• Pin 2 (Tx-) to Pin 6 (Rx-)
• Pin 3 (Rx+) to Pin 1 (Tx+)
• Pin 6 (Rx-) to Pin 2 (Tx-)

LED Indicators

The front panel LEDs indicate the status of the switch:

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows connection to any Ethernet device using either straight-through or cross-over cables, as the ports automatically detect the required connection type.

Dual Speed Functionality and Switching

The switch's RJ45 ports support auto-negotiation for 10/100 Mbps speeds. All Moxa EtherDevice Switch models are plug-and-play, requiring no software configuration for installation or maintenance. Duplex modes (half/full) are also auto-negotiated based on the connected device's capabilities.

Switching, Filtering, and Forwarding

The switch operates in store-and-forward mode. Packets are filtered if source and destination addresses are on the same port segment. Packets for other segments are forwarded to the appropriate port. Network maintenance packets are sent to all ports. This mode eliminates bad packets and optimizes performance during heavy traffic.

Switching and Address Learning

The switch maintains an address table for up to 1K node addresses, suitable for large networks. The tables are self-learning; new node locations are added automatically. An address-aging algorithm removes least-used addresses. To reset the address buffer, power cycle the unit.

Auto-Negotiation and Speed Sensing

All RJ45 Ethernet ports support auto-negotiation for 10BaseT and 100BaseTX speeds, adhering to IEEE 802.3u. Nodes can operate at different speeds simultaneously. Auto-negotiation occurs upon cable connection and LINK enablement. If connected to a non-negotiating device, the port defaults to 10 Mbps and half-duplex mode as per IEEE 802.3u.
