Mounting Dimensions (unit = mm)
DIN-Rail Mounting
The aluminum DIN-rail attachment plate should be fixed to the back panel of the IMC-101 when you take it out of the box. If you need to reattach the DIN- rail attachment plate to the IMC-101, make sure the stiff metal spring is situated towards the top, as shown in the figures below.
To remove the IMC-101 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 IMC-101 on the
wall, as illustrated below.
NOTE: Test the screw head and shank size by inserting the screw into one of the keyhole shaped apertures of the wall-mounting plate.
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.

Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power has been switched off or
the area is known to be non-hazardous. The devices may only be connected to
the supply voltage shown on the type plate.
The devices are designed for operation with a safety extra-low voltage. Thus, they may only be connected to the supply voltage connections and to the signal contact with the safety extra-low voltages (SELV) in compliance with IEC 60950- 1/VDE0805.
**** WARNING
Substitution of components may impair suitability for Class I, Division 2 and
Zone 2.
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. During installation into certain end equipment,
it must comply with fire enclosure stipulations of IEC 60950-1, or similar
statements.
SAFETY FIRST
Be sure to disconnect the power cord before installing and/or wiring your Moxa
IMC-101.
SAFETY FIRST
Calculate the maximum possible current allowed in each power wire and common
wire. Observe all electrical codes dictating the maximum current allowed 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 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 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. -
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 separated.
-
It is strongly advised that you label wiring to all devices in the system when necessary.
Grounding the IMC-101
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.
A 4 mm² conductor must be used when a connection to the external grounding
screw is used.
Wiring the Alarm Contact
The alarm contact is made up of the two middle contacts of the terminal block
on the IMC-101’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:
-
The IMC-101 has lost power from one of the DC power inputs.
OR -
One of the 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.
Wiring the Redundant Power Inputs
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-101’s top panel.
NOTE Terminal block with 28 to 12 AWG (torque value 4.5 lb-in) should be used with the devices.
**** ATTENTION
The IMC-101 supports redundant power input. Before connecting the IMC-101 to
the DC power input, make sure these two DC power sources are stable.
Communication Connections
The IMC-101 has 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) ports located on the IMC-101’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. 10/100Base T(x) RJ45 Pinouts
RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring
RJ45 (8-pin) to RJ45 (8-pin) Crossover Cable Wiring
100BaseFX Ethernet Port Connection
The concept behind the SC port and cable is easy to understand. 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 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).
ATTENTION
This is a Class 1 Laser/LED product. Do not stare into the laser beam.
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-101’s power needs.
Alarm Contact
The IMC-101 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 set
up 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-101 has lost power from one of the DC power inputs, or (2) one of the 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.
Dip Switch Setting
Dip Switch 1 (Default: Off)
ON: Enables the PORT Alarm. If the port’s 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 fault LED will never light up.
Dip Switch 2 (Default: ON)
ON: Enables full duplex for 100BaseFX
Off: Disables full duplex for 100BaseFX
Dip Switch 3
Reserved for future use
To activate the updated DIP switch setting, power off and then power on the
IMC-101.
LED Indicators
The front panel of the IMC-101 contains several LED indicators. The function
of each LED is described in the table below.
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IMC-101’s 10/100BaseTX
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-101 to Ethernet devices.
Dual-Speed Functionality and Switching
The IMC-101’s 10/100 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-101 are plug-and-play devices, so that software
configuration is not required at installation, or during maintenance. The half
/full-duplex mode for the RJ45 switched 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.
Auto-Negotiation and Speed Sensing
All of the IMC-101’s RJ45 Ethernet ports independently support autonegotiation
for transmission speed in the 10BaseT and 100BaseTX modes in operations
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 RJ45 cable connection is made, and then each time a LINK is enabled. The IMC-101 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 similarly. Depending on what type of device is connected, this will result in an agreement to operate at a speed of either 10 Mbps or 100 Mbps.
If the IMC-101’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.
