Installing the MRC-1002 Gateway
The metal DIN-rail kit is fixed to the back panel of the MRC-1002
gateway when you take it out of the box. Mount the MRC-1002 gateway
on corrosion-free mounting rails that meet the EN 60715 standard.
STEP 1:
Click on the DIN rail and push
down into the mounting rail.
STEP 2:
Push the MR
C-1002 gateway
forward
until it snaps into
place.
Removing the MRC-1002 Gateway
STEP 1:
Use a flat
-type screwdriver to
pull down the spring of the DIN
rail kit.
STEP 2:
Pull back the MRC
-1002
gateway until it
releases from
the mounting rail.
Wiring Requirement
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 dev
ices 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
IEC950/ EN 60950/VD E0805/IEC 61010 c
lass 2.
ATTENTION
This unit is a built
-in open type. When the unit is installed in
another piece of equipment, the equipment enclosing the unit
must comply with fire enclosure regulation IEC 60950/EN60950
(or similar regulation).

- 6 -
ATTENTION
Safety First!
Be sure to disconnect the power cord before in
stalling and/or
wiring your MRC
-1002 gateway.
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.
Please read and follow these guidelines:
•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 through 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.
•You should separate input wiring from output wiring.
•We advise that you label the wiring to all devices in the system.
Wiring the Power Input (12-36V DC)
Connect the power adapter with the 3-pin terminal block on the top
panel of the MRC-1002 gateway and push the power terminal block into
the terminal block socket. When the system boots up, the system is
ready, and the Power LED will light up.
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
located
on the top panel of the MRC-1002
gateway.
STEP 1 / STEP 2:
STEP 3:
ATTENTION
Before connecting the MRC
-1002 gateway to the DC power
input, make sure the DC power source voltage is stable. The
wire must be able to withstand at least 105°C.

Grounding the MRC-1002 Gateway
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the terminal block 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 Relay Contact
The MRC-1002 Series has one relay output. This relay contact uses two
contacts of the terminal block on the bottom panel of the MRC-1002
gateway. 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 illustrate the meaning of the two contacts used to connect
the relay contact.
FAULT:
The two contacts of the 5-pin terminal block connector are used to
detect user-configured events. The two wires attached to the fault
contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the fault circuit
remains closed.
Wiring the Digital Input
The MRC-1002 gateway has one digital input (DI). The DI consists of
two contacts of the 5-pin terminal block connector on the MRC-1002
bottom panel, which are used for the DC input. The top view of the
terminal block connectors is shown above.
STEP 1: Insert the negative (ground)/positive DI wires into the ┴/I
terminals, respectively.
STEP 2: To keep the DI 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 bottom panel of the
MRC-1002 gateway.

Wiring the Serial Ports
The MRC-1002 gateway has one serial port. Each port can be
configured by software for RS-232, RS-422, or RS-485. The pin
assignments for the ports are shown in the following table.

SIM Card Socket
The MRC-1002 gateway LTE version comes with a SIM card socket
(normal SIM size) for cellular communications. The SIM card socket is
located at the lower part of the front panel. To install them, remove the
screw and the protection cover to access the socket, and then plug the
SIM card into the socket directly. You will hear “click” when finished.
Push the SIM card again to release it from the socket.
Cellular Antenna
The MRC-1002 gateway cellular
version has two antennas in the
package. Screw
the antennas into
the cellular sockets marked as W1
and W2 on the front panel.

USB Port
The USB 2.0 port (type A connector) is located at the lower part of the
front panel, and supports a USB storage device driver for FAT, FAT32
and NTFS. The pinout of the USB port is as below.

Ethernet Ports
The 10/100BaseT(X) ports located on the front panel of the MRC-1002
gateway are used to connect to Ethernet-enabled devices. The ports
are at “Auto MDI/MDI-X” mode by default, which is suitable for
straight-through or cross-over Ethernet cables. 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.
