DIN-Rail Mounting
The aluminum DIN-rail attachment plate should be fixed to the back panel
of the IMC-101G when you take it out of the box. If you need to reattach
the DIN-rail attachment plate to the IMC-101G, 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 IMC-101G from the DIN rail, reverse steps 1 and 2 above.

- 5 -
Wall Mounting (Optional)
For some applications, you will find it convenient to mount the IMC-101G
on the wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-rail attachment plate
from
the IMC-101G and
then attach the wall
-
mount
plates, as shown in the
diagrams below.
STEP 2:
Mounting
the IMC-101G on the wall requires four
screws. Use the IMC
-101G, with wall-mount plates
attached, as a guide to mark the correct locations of
the
four
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
on
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.
STEP 3:
Once the screws are fixedin the wall,
insert the four screw
heads through
the
large parts of the
keyhole
-
shaped apertures and then
slide
the IMC-101G downwards, as
indicated
in the diagram
. Tighten the
four screws for added stability.

switched off
or the area is known to be nonhazardous. The
devices may only be connected to the supply voltage shown on
the type plate.
These devices must be supplied by a SELV source as defined in
the Low Voltage Directive 2006/95/EC.
ATTENTION
This unit is a built
-in type. It must comply with fire enclosure
stipulations of IEC60950
-1/EN60950-1, or similar statements,
when installed in certain end equipment.

- 7 -
ATTENTION
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum
allowed current
for each wire size. If the current goes
above the
allowed maximum
, the wiring could overheat, causing
serious damage to your equipment.
You should also pay attention to the following points:
•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 point of intersection.
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.
•You 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.
•Keep input wiring and output wiring separate.
•It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding the IMC-101G
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
grounding screw to the grounding surface before connecting devices.
ATTENTION
This product is intended to be mounted to a well
-grounded
mounting surface such as a metal panel.
WARNING
HOT SURFACE
, DO NOT TOUCH!! Before touching the surface,
make sure it has cooled sufficiently so as not
to damage your
skin, or wear gloves designed to protect against heat.
This equipment is intended to be used in a Restricted Access Location that
is only accessible by SERVICE PERSONNEL or by USERS who have been
instructed that the metal chassis of the equipment is so hot that
appropriate precautions should be taken before touching it. The
Restricted Access Location should only be accessible through the use of a
key or security identity system.

Wiring the Alarm Contact
The Alarm Contact is made up of the two middle contacts of the terminal
block on the IMC-101G’s top panel. Refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector
and how to attach the terminal block connector to the terminal block
receptor.
In this section, we explain the meaning of the two contacts used to
connect the alarm contact.
FAULT: The two middle contacts of the
6
-contact terminal block connector are
used to
detect both power faults and port faults. The
two wires attached to the
fault contacts form
an open circuit when
:
1.
The IMC-101G
has lost power from one of
the DC power inputs.
OR
2.
One of the ports for which the
corresponding PORT ALARM DIP Swit
ch is
set to ON is not properly connected.
If neither of these two conditions
is met, the
f
ault circuit will be closed.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the IMC-101G’s top panel are used for the
IMC-101G’s two DC inputs. The top and front views of one of the terminal
block connectors are shown here.
STEP 1:
Insert the negative/positive DC wires into the
V
-/V+ terminals, respectively.
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-101G’s top panel.
NOTE
Use copper conductors only; 12-28 AWG gauge, 4.5 in-lb torque.
ATTENTION
Before connecting the IMC
-101G
to the DC power inputs, make
sure the DC power source voltage is stable.

Communication Connections
All IMC-101G models have one 10/100/1000BaseT(X) Ethernet port and
one 1000Base SFP fiber port.
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) ports located on the IMC-101G’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 crossover
Ethernet cables.

1000BaseSFP Fiber Port
The gigabit Ethernet ports on the IMC-101G are 1000BaseSFP fiber ports,
which require using gigabit mini-GBIC fiber transceivers to work properly.
The concept behind the LC 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.
Remember 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 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).
LC-Port Pinouts
LC-Port to LC-Port Cable Wiring
Optical transceivers installed in the field should be UL certified, Class I
category, with a clearly visible CDRH certification marking on the
transceiver equivalent to: “Complies with 21CFR 1040.10 and 1040.11”.
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 IMC-101G’s power needs.

- 11 -
Alarm Contact
The IMC-101G has one alarm contact located on the top panel. For
detailed instructions on how to connect the alarm contact power wires to
the two middle contacts of the 6-contact terminal block connector, see
the “Wiring the Alarm Contact” section above. A typical scenario would be
to connect the fault circuit to a warning light located in the control room.
The light can be configured to switch on when a fault is detected.
The alarm contact has two terminals that form a fault circuit for
connecting to an alarm system. The two wires attached to the fault
contacts form an open circuit when (1) the IMC-101G has lost power from
one of the DC power inputs, or (2) one of the TP/SFP ports for which the
corresponding PORT ALARM DIP Switch is set to ON is not properly
connected. If neither of these two conditions occurs, the fault circuit will
be closed.
IMC-101G DIP Switch Setting
NOTE
To activate updated DIP switch settings, power off and then
power on the IMC-101G.
Dip Switch 1
(Default: Off)
On:
Enables the PORT ALARM. If the product
experiences a power failure, or the Ethernet port
link fails,
the relay will form an open circuit and the
fault LED will light up.
Off:
Disables the corresponding PORT ALARM. The
relay will form a closed circuit and the f
ault LED will
never light up.
Dip Switch 2
(Default: On) On: Enables LFP (Link Fault Pass-through). To enable the IMC-101 for LFP, set the SFP port to Auto
mode.
Off:
Disables LFP (Link Fault Pass-through)
Dip Switch 3
(Default: On)
On:
SFP port in Auto (auto-negotiation) mode
Off:
Forces SFP port to 1000M
Dip Switch 4
Reserved for future use
ATTENTION
When Force mode is used, the LFP function will be disabled.

Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IMC-101G’s
10/100/1000BaseT(X) ports to any kind of Ethernet device, without
paying attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or crossover cable to connect the IMC-101G to Ethernet devices.
Dual-Speed Functionality and Switching
The IMC-101G’s 10/100/1000 Mbps RJ45 switched port auto negotiates
with the connected device for the fastest data transmission rate
supported by both devices. All models of the IMC-101G are plug-and-play
devices, so that software configuration is not required at installation, or
during maintenance. The half-duplex or full-duplex mode for the RJ45
switched ports is user dependent and changes (by auto-negotiation) to
full-duplex or half-duplex, depending on which transmission speed is
supported by the attached device.
Auto-Negotiation and Speed Sensing
All of the IMC-101G’s RJ45 Ethernet ports independently support
auto-negotiation for transmission speeds of 10 Mbps, 100 Mbps , and
1000 Mbps, 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 or 1000 Mbps.

- 13 -
Auto-negotiation takes place when an RJ45 cable connection is made.
Each time a LINK is enabled, the IMC-101G advertises its capability for
using 10 Mbps, 100 Mbps, or 1000 Mbps transmission speeds, with the
device at the other end of the cable expected to advertise similarly.
Depending on what type of device is connected, this will result in
agreement to operate at a speed of 10 Mbps, 100 Mbps, or 1000 Mbps.
If an IMC-101G’s 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 standard.

NOTE
The actual communication distance depends on many factors,
including connector loss, cable deployment, and the age of the
cabling system. We recommend doing a link budget analysis and
reserving a 3 dB margin for such factors.
