Overview

The IMC-P101 series is an Ethernet to fiber optic media converter. It provides
Ethernet media conversion from 10/100 BaseT(X) to 100 BaseFX(SC/ST
connectors). These media converters are classified as power source equipment
(PSE), and when used in this way, the IMC-P101 series provides up to 15.4
watts to powered devices (PD). The IMC-P101 series can be used to power
IEEE 802.3af compliant powered devices (PD), eliminating the need for
additional wiring, and supports IEEE 802.3/802.3u/802.3x with 10/100M,
full/half-duplex, and MDI/MDI-X auto-sensing to provide a total solution for
your industrial Ethernet network.

DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should be fixed to the back panel of
the IMC when you take it out of the box. If you need to reattach the DIN-Rail
attachment plate to the IMC, make sure the stiff metal spring is situated

towards the top, as shown in the figures below.

STEP 1:

Insert the top of the DIN-Rail into the
slot just below the stiff metal spring.

STEP 2:

The DIN-Rail attachment unit will

snap into place as shown below.

To remove the Moxa Industrial Media Converter from the DIN-Rail, simply
reverse Steps 1 and 2 above.

Wall Mounting (Optional)

For some applications, you will find it convenient to mount the Moxa PoE
Media Converter on the wall, as illustrated below.

STEP 1:

Remove the aluminum DIN-Rail attachment plate from the Moxa PoE Media
Converter, and then attach the wall mount plates, as shown in the diagrams

below.

STEP 2:

Mounting the Moxa PoE Media Converter on the wall
requires 4 screws. Use the IMC, with wall mount plates
attached, as a guide to mark the correct locations of the 4
screws. The heads of the screws should be less than 6.0
mm in diameter, and the shafts should be less than 3.5
mm in diameter, as shown in the figure at the right.

NOTE

Test the screw head and shank size by inserting
the screw into one of the keyhole shaped
apertures of the Wall Mounting Plates, before it
is screwed into the wall.

Do not screw the screws in all the way—leave a space of
about 2 mm to allow room for sliding the wall mount
panel between the wall and the screws.

6.0 mm

3.5 mm

STEP 3:

Once the screws are fixed in the wall, insert the four screw heads through the
large openings of the keyhole-shaped apertures, and then slide Moxa PoE
Media Converter downwards, as indicated below. Tighten the four screws for

added stability.

Grounding the Moxa Industrial Media
Converter

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.

Wiring the Redundant Power Inputs

The top five contacts of the 8-contact terminal block connector on the IMC’s
top panel are used for the IMC’s two DC inputs. Top and front views of one of
the terminal block connectors are shown here.

Top View

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 the IMC’s top panel.

ATTENTION

Before connecting the IMC to DC power inputs, make sure
the DC power source voltage is stable.

Communication Connections

IMC-P101 models have one 10/100BaseT(X) Ethernet port, and one
100BaseFX (SC or ST type connector) fiber port.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) Ethernet port located on the IMC’s front panel is used to
connect to Ethernet-enabled devices.

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

100BaseFX Ethernet Port Connection

The concept behind the SC port and cable is quite straightforward. Suppose
you are connecting devices I and II. Unlike 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.

All you need to remember is to connect the Tx (transmit) port of device 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 are making 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).

Redundant Power Inputs

Both power inputs can be connected simultaneously to live DC power sources.
If one power source fails, the other live source acts as a backup, and
automatically supplies all of the Moxa Industrial Media Converter’s power
needs.

DIP Switch Setting

1234567

ON DIP

DIP No. Function ON OFF

1 Auto Negotiation Enable* Disable

“ON”: Enables “Auto Negotiation” function, the speed and duplex states for

each port link segment are automatically configured using the highest
performance interoperation mode.

“OFF”: Disables “Auto Negotiation” function, the speed and duplex states

depend on the manual setting configuration.

2 Force TP Speed 100Mbps* 10Mbps

(Only when Auto Negotiation is disabled)

“ON”: Forces 100Mbps on Ethernet port.

“OFF”: Forces 10Mbps on Ethernet port.

3 Force TP Duplex Full Duplex* Half Duplex

(Only when Auto Negotiation is disabled)

“ON”: Forces Full Duplex on Ethernet port.

“OFF”: Forces Half Duplex on Ethernet port.

4 Link Fault Pass Through Enable* Disable

“ON”: Enables “Link Fault Pass Through”, the link status on the TX port will

inform the FX port of the same device and vice versa.

“OFF”: Disables “Link Fault Pass Through”, the link status on the TX port

will not inform the FX port.

5 Operating Mode Store-and-Forward* Pass Through

- 11 -

DIP No. Function ON OFF

“ON”: Selects “Store-and-Forward” mode, begins to forward a packet to a

destination port after an entire packet is received. The latency depends
on the packet length.

“OFF”: Selects “Pass Through” mode, operates with the minimum latency.

Both transceivers are interconnected via internal MIIs and the
internal switch engine and data buffer are not used.

Note: With “Pass Through” mode enabled, the Ethernet port and fiber port

should transmit at 100 Mbps, which is equivalent to full duplex mode.

6 PSE Disable Enable*

PSE: Power Source Equipment.

“ON”: Disables “PSE”, IMC-P101 series do NOT provide power to PD

(Powered Device).

“OFF”: Enables “PSE”, IMC-P101 series provides power to PD (Powered

Device).

7 P.R.R. Enable Disable*

P.R.R.: Power Remote Reset

“ON”: Enables “P.R.R” function, when fiber port link down 3 seconds and

“PSE” setting is enabled, IMC-P101 series STOP providing power to
PD (Power Device) which means the PD power will turn OFF. After 1
second later, IMC-P101 series start to continue provide power to PD,
and then the PD power turn back ON for reset PD.

“OFF”: Disables “P.R.R” function, no reset PD function.

(*): Default DIP switch setting.

ATTENTION

After changing the DIP switch setting, you will need to
power off and then power on the IMC-P101 to activate the
new setting.
