Overview
The MOXA EtherDevice™ EDS-305-M12 series of 5-port smart Ethernet
switches provides a hardened and cost-effective solution for your Ethernet
connections. The EDS-305-M12 switches are IP67-rated to provide protection
against shock and foreign particles. IP67-rated products have the following
characteristics: (1) dust proof, (2) protection against the effects of temporary
immersion in water.
The EDS-305-M12 switches have a wide operating temperature range of -40
to75°C, and are designed to withstand a high degree of vibration and shock.
The rugged hardware design makes the EDS-305-M12 switches perfect for
ensuring that your Ethernet equipment can withstand the rigors associated with
critical industrial applications. The switches are rated for use in hazardous
locations (Class 1 Division 2/Zone 2), and comply with CE, FCC, UL, DNC,
and GL Standards.

Wiring Requirements
WARNING
Turn the power off before disconnecting modules or wires. The
correct power supply voltage is listed on the product label. Check
the voltage of your power source to make sure that you are using
the correct voltage. Do NOT use a voltage greater than what is
specified on the product label.
These devices must be supplied by a SELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your MOXA switch.
This device has UL508 approval. Use copper conductors only,
60/75°C, Tighten To 4.5 pound-inches
ATTENTION
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size. If the current goes
above the maximum ratings, the wiring could overheat, causing
serious damage to your equipment.
You should also heed the following guidelines:
yUse 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.
yYou can use the type of signal transmitted through a wire to determine
which wires should be kept separate. The rule of thumb is that wiring that
shares similar electrical characteristics can be bundled together.
yKeep input wiring and output wiring separated.
yIt is strongly advised that you label wiring to all devices in the system when
necessary.
Grounding the EDS-305-M12
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.
10/100BaseT(X) Ethernet Port
Connection
All EDS-305-M12 models have 5 10/100BaseT(X) Ethernet ports (4-pin
shielded M12 socket with D coding). The 10/100TX ports located on the
EDS-305-M12’s front panel are used to connect to Ethernet-enabled devices.
Most users configure these ports for Auto MDI/MDI-X mode, in which case
the port’s pinouts are adjusted automatically depending on the type of Ethernet
cable used (straight-through or cross-over), and the type of device (NIC-type or
HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.

Dual Speed Functionality & Switching
The EDS-305-M12’s 10/100 Mbps switched M12 ports auto negotiate with the
connected device to use the fastest data transmission rate supported by both
devices. All of MOXA’s EtherDevice switches are plug-and-play devices, so
that software configuration is not required. The half/full duplex mode for the
switched M12 ports is user dependent and changes (by auto-negotiation) to full
or half duplex, depending on which transmission speed is supported by the
attached device.

Switching and Address Learning
The EDS-305-M12 has an address table that can hold up to 1000 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-305-M12 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.
Switching, Filtering, and Forwarding
Each time a packet arrives at one of the switched ports, a decision is made to
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.
A packet with destination address on another port segment will be forwarded to
the appropriate port, and will not be sent to the other ports where it is not
needed. Packets that are used in maintaining the operation of the network (such
as the occasional multi-cast packet) are forwarded to all ports.
The EDS-305-M12 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.
LED Indicators
Several LED indicators are located on the EDS-305-M12’s front panel. The
function of each LED is described in the table below.

Auto-Negotiation and Speed Sensing
All of the EDS-305-M12’s Ethernet ports independently support
auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with
operation according to the IEEE 802.3u standard. This means that some nodes
could be operating at 10 Mbps, while at the same time, other nodes are
operating at 100 Mbps.
Auto-negotiation takes place when an M12 cable connection is made, and then
each time a LINK is enabled. The EDS-305-M12 advertises its capability for
using either 10 Mbps or 100 Mbps transmission speeds, with the device at the
other end of the cable expected to advertise in the same way. Depending on
what type of device is connected, this will result in agreement to operate at a
speed of either 10 Mbps or 100 Mbps.
If an EDS-305-M12’s Ethernet port is connected to a non-negotiating device, it
will default to 10 Mbps speed and half-duplex mode, as required by the IEEE
802.3u standard.
