Overview

The Moxa Industrial Media Converter IMC-21 series cons ists of entry-level
10/100BaseT(X) to 100BaseFX media converters that provide a
cost-effective solution, and are specially designed for reliable and stable
operation in harsh industrial environments.

IMC-21 accepts either a 12 to 48 VDC power input. It operates reliably in
a temperature range from -10 to 60°C, and IMC-21’s rugged hardware
design makes it ideal for demanding industrial applications, such as those
that comply with FCC, CE.

Mounting Dimensions

IMC-21 series (10/100BaseT(X) to 100BaseFX)

DIN-Rail Mounting

The plastic DIN-Rail attachment plate should already be fixed to the rear
panel of IMC when you take it out of the box. If you need to reattach the
DIN-Rail attachment plate to IMC, 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.

To remove Moxa IMC-21 from the
DIN

-Rail, insert a flat-blade screw

driver horizontally into the DIN

-Rail

kit under the IMC-21, and then pull it
upwards and release IMC towards you
away from the DIN

-Rail.

Wiring Requirements

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or
wiring your Moxa

Industrial Media Converter.

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 rating, the wiring could
overheat, causing serious damage to your equipment.

You should also pay attention to the following point s:

• Use 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 communicat ions wiring and power wiring
in the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.

• You can use the type of signal transmitted through a wire to
determine which wires should be k ept separat e. The ru le of thumb is
that wiring that shares similar electrical characteristics can be
bundled together.

• Keep input wiring and output wiring separated.

• It is strongly advised that you label wiring to all devices in the system
when necessary.

Grounding Moxa Industrial Media Converter

Top View

Front View

Grounding and wire routing help limit the effect s
of noise due to electromagnetic interference
(EMI). Run the ground connection from th e right
most

connector of the 3-

contact terminal block to

the grounding surface prior to connec

ting

devices.

ATTENTION

This product is intended to be mounted to a well

-grounded

mounting surface such as a metal panel.

Wiring the Power Inputs

The two left-most contacts of the 3-contact terminal block connector on
IMC’s top panel are used for IMC’s DC or AC inputs. Top and front views of
one of the terminal block connectors are shown h ere.

Front View

STEP 1:

Insert the negative/positive DC wires

into the V

-/V+ terminals.

STEP 2: To keep the DC wires from pulling loose,

use a small flat-blade screwdriver to tighten the
wire

-clamp screws on the front of the terminal

block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block
receptor, which

is located on IMC’s top panel.

Communication Connections

IMC-21 has one 10/100BaseT(X) Ethernet port.

RJ45 Ethernet Port Connection

The 10/100BaseT(X) port located on IMC’s front panel are used to
connect to Ethernet-enabled devi ces .

Below we show pinouts for both MDI (NIC-type) and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

Fiber Optical 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 signa ls,
optical signals do not require a circuit in order to transmit data.
Consequently, one of the optical lines is used to transmit data from d evice
I to device II, and the other optical line is used transmit data from dev ice
II to device I, for full-duplex transmission.

All you need to remember is to connect the Tx (tra nsmit) port of de vice I
to the Rx (receive) port of device II, and the Rx (receive) port of device I
to the Tx (transmit) port of device II. If you make your own cable, we
suggest labeling the two sides of the same line with the same letter
(A-to-A and B-to-B, as shown below, or A1-to-A2 and B1-to-B2).

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect Moxa Industrial
Media Converter’s 10/100BaseT(X) ports to any kind of Ethernet device,
without paying attention to the type of Et hernet ca ble being u sed for the
connection. This means that you can use either a straight-through cable
or cross-over cable to connect IMC to Ethernet devices.

Dual Speed Functionality and Switching

Moxa Industrial Media Convert er’s 10/100 Mbps switched RJ45 port auto
negotiates with the connected device for the f astest data transmission
rate supported by both devices. All models of Moxa Industrial Media
Converter are plug-and-play devices, so that software configuration is not
required during installation, or for maintenance. The half/full duplex
mode for the switched RJ45 ports is user dependent and changes (by
auto-negotiation) to full or half duplex, depending on wh ich transmission
speed is supported by the attached device.

Auto-Negotiation and Speed Sensing

Moxa IMC-21 series’ RJ45 Ethernet port supports auto-negotiation in
10BaseT and 100BaseT(X) modes, with operation governed by 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 RJ45 cable connection is made, and

then each time a LINK is enabled. Moxa Industr ial Media Converter
advertises its capability for using either 10 Mbps or 100 Mbps
transmission speeds, with the device at the ot h er end of the cable
expected to advertise similarly. Depending on what type of device is
connected, this will result in agreement to opera te at a speed of either 10
Mbps or 100 Mbps.

If a Moxa Industrial Media Converter RJ45 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 standar d.
