EDS-208 Series Quick Installation Guide Moxa EtherDevice Switch Edition 5.2, February 2020 Technical Support Contact Information www.moxa.
Overview The EDS-208 series of Moxa EtherDevice™ Switches are entry-level 8port Ethernet Switches that provide a cost-effective solution for industrial Ethernet connections. EDS-208 provides a choice of 12 to 48 VDC power input. The switches can operate reliably in a temperature range of -10 to 60°C, and the rugged hardware design makes EDS-208 perfect for ensuring that your Ethernet equipment can be used in demanding industrial environments.

Mounting Dimensions (unit = mm) DIN-Rail Mounting The plastic DIN-Rail attachment plate should already be fixed to the rear panel of EDS-208 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate to EDS-208, make sure the DIN-Rail kit is situated towards the top, as shown in the figures below. STEP 1: Insert the top of the DIN-Rail into the slot. STEP 2: The DIN-Rail attachment unit will snap into place as shown below.
You may also take the following steps to remove the EDS-208 from the DIN-Rail. STEP 1: STEP 2: Press the middle of the flat side of Release it towards you and away the mounting kit as indicated. Pull from the DIN-Rail. the EDS-208 downwards. Wiring Requirements ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring your EDS-208. Calculate the maximum possible current in each power wire and common wire.
Grounding EDS-208 Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the right most contact of the 3-contact terminal block 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.
Communication Connections EDS-208 has 7 or 8 10/100BaseT(X) Ethernet ports, and 1 or 0 (zero) 100BaseFX (SC/ST-type connector) multi-mode fiber ports. 10/100BaseT(X) Ethernet Port Connection The 10/100BaseT(X) ports located on EDS-208’s front panel are used to connect to Ethernet-enabled devices. Below we show pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports, and also show cable wiring diagrams for straight-through and cross-over Ethernet cables.
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 to transmit data from device II to device I, for full-duplex transmission.
LED Indicators The front panel of EDS-208 contains several LED indicators. The function of each LED is described in the table below.
Switching and Address Learning EDS-208 has an address table that can hold up to 1,000 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, EDS-208 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.
