Hardware Installation
3.1 DIN-rail Installation
The router comes with a DIN-rail kit to allow you to fasten the router to a DIN-rail in any
environments.
DIN-rail Kit Measurement
Step 1: Slant the router and screw the Din-rail kit onto the back of the router, right in the
middle of the back panel.
Step 2: Slide the router onto a DIN-rail from the Din-rail kit and make sure the router clicks
into the rail firmly.

IAR-142-/142+-3G User Manual
ORing Industrial Networking Corp. 9
3.2 Wall Mounting
Besides Din-rail, the router can be fixed to the wall via a wall mount panel, which can be
found in the package.
Wall-Mount Kit Measurement
To mount the router onto the wall, follow the steps:
Step 1: Screw the two pieces of wall-mount kits onto both ends of the rear panel of the router.
A total of six screws are required, as shown below.
Step 2: Use the router, with wall mount plates attached, as a guide to mark the correct
locations of the four screws.
Step 3: Insert four screw heads through the large parts of the keyhole-shaped apertures, and
then slide the router downwards. Tighten the four screws for added stability.

IAR-142-/142+-3G User Manual
ORing Industrial Networking Corp. 10
The screws should be 6mm diameter head x 3mm diameter thread, as
shown below. Note that the screws should not be larger than the size
used in the series to prevent damaging the router.
3.3 Wiring
WARNING
Be sure to switch off the power and make sure the area is not hazardous
before disconnecting modules or wires. The devices may only be connected to
the supply voltag shown on the type plate.
3.3.1 Grounding
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.
3.3.2 Dual Power Inputs
The router has two sets of power inputs, power input 1 and power input 2, on a 4-pin terminal
block on the router’s top panel. Follow the steps below to wire redundant power inputs.
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.
Note: besides power input, the router can also be powered by a PoE PSE such as switch via
its PoE-enabled WAN port.

ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your
routers.
2. 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.
3. If the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.
4. 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.
5. 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.
6. 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
sharing similar electrical characteristics can be bundled together
7. You should separate input wiring from output wiring
8. It is advised to label the wiring to all devices in the system

Management Interface
5.1 Installation
Before installing the router, you need to be able to access the router via a computer equipped
with an Ethernet card or wireless LAN interface. To simplify the connection, it is
recommended to use an Ethernet card to connect to a LAN.
Follow the steps below to install and connect the router to PCs:
Step 1: Select power source. The router can be powered by +12~48V DC power input, or via
a PoE (Power over Ethernet) PSE Ethernet switch.
Step 2: Connect a computer to the router. Use either a straight-through Ethernet cable or
cross-over cable to connect the ETH1 port of the router to a computer. Once the LED of the
LAN port lights up, which indicates the connection is established, the computer will initiate a
DHCP request to retrieve an IP address from theAP router.
Step 3: Configure the router on a web-based management utility. Open a web browser on
your computer and type http://192.168.10.1 (default gateway IP of the router) in the address
box to access the webpage. A login window will pop up where you can enter the default login
name admin and password admin. For security reasons, we strongly recommend you to
