Package Checklist
Moxa’s OnCell G3150A-LTE is shipped with the following items. If any of
these items is missing or damaged, please contact your customer service
representative for assistance.
• 1 OnCell G3150A-LTE unit
• 2 2G/3G/4G antennas 2 dBi omni-directional with SMA male
connectors
• 1 DIN-rail mounting kit
• Quick installation guide (printed)
• Warranty card
Installation and Configuration
Before installing the OnCell G3150A-LTE, make sure that all items in the
package checklist are in the box. In addition, you will need access to a
notebook computer or PC equipped with an Ethernet port. The OnCell
G3150A-LTE has a default IP address that you must use when connecting
to the device for the first time.
Take the following steps to configure your OnCell G3150A-LTE. Refer to
the Panel Layout of the OnCell G3150A-LTE
section below for the location
of the ports and sockets.
Step 1: Insert a SIM card and turn on the OnCell G3150A-LTE
1. Use a screwdriver to loosen the screws and remove the SIM card
cover.
2. Insert one or two 2G/3G/4G SIM cards (full-sized SIM/1FF) into the
SIM card slots located on the bottom of the OnCell G3150A-LTE.
If you are only using one SIM card, insert it in the top slot (slot 1; the
card in slot 1 is referred to as SIM1).
By default, the SIM card in the slot 1 is treated as the primary card.
To change the default to SIM2 (the card in slot 2), log in to the
OnCell’s web UI, and configure SIM2 as the primary card. When the
OnCell device is turned on, it boots up based on the configuration
information stored on the primary SIM card.
3. Turn on the OnCell G3150A-LTE by connecting a power terminal
block to a DC power source (12 to 48 VDC). For details refer to the
Connecting the Power Input
section.
4. Reattach the cover.

Step 2: Connect the OnCell G3150A-LTE to a notebook or PC
Since the OnCell G3150A-LTE supports MDI/MDI-X auto-sensing, you can
use either a straight-through cable or crossover cable to connect the
OnCell G3150A-LTE to a computer. See the
10/100BaseT(X) Ethernet
Port Connection section below for detailed instructions. If the LED
indicator on the OnCell G3150A-LTE’s LAN port lights up, it means a
connection has been established.
Step 3: Set up an IP address for the computer
Set an IP address on the same subnet as the OnCell G3150A-LTE. Since
the OnCell G3150A-LTE’s default IP address is 192.168.127.254, and the
subnet mask is 255.255.255.0, you should set the IP address of the
computer to 192.168.127.xxx and subnet mask to 255.255.255.0.
Step 4: Use the web-based manager to configure the OnCell
G3150A-LTE
Open your computer’s web browser and type http://192.168.127.254
in the address field to access the homepage of the web-based
management system. Before the homepage opens, you will need to enter
the username and password. For first-time configuration, enter the
default username and password given below:
Username: admin
Password: moxa
Click on the Login button.
For security reasons, we strongly recommend changing the
password. To
change the password, select Maintenance
, and then follow the on-screen
You must either click the Save Configuration or the Restart
button for the configuration changes to take effect.

Device Dimensions
DIN-Rail Mounting
DIN-Rail Kit Dimensions
Unit = mm (inch)
The OnCell G3150A-LTE Series computers come with a DIN-rail kit
attached to the back panel. Mount the OnCell G3150A-LTE Series on
corrosion-free mounting rails that meet the EN 60715 standard.

STEP 1: Insert the upper lip of the DIN rail into the top hook of the
DIN
Press the OnCell G3150A-LTE S
eries towards the DIN rail until it
snaps into place.
To remove the OnCell G3150A-LTE from the DIN rail, reverse steps 1 and
2 above.
Wall Mounting (optional)
Wall-Mounting Kit
Dimension
For some applications, it may be more convenient to mount the OnCell
G3150A-LTE to a wall, as illustrated below:
STEP 1:
Remove the aluminum
DIN-rail attachment plate
from the OnCell
G3150A
plates with M3 screws, as
shown in the adjacent
diagram.

STEP 2:
Mounting the OnCell
to a wall requires 4
screws. Use the OnCell
device, 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.
Test the screw head and shank size by inserting the screws into
one of the k
eyhole shaped apertures of the wall-mounting p
lates
before attaching the plates to the wall.
STEP 3:
Once the screws are fixed into the
wall, insert the four screw heads
through the large opening of the
keyhole
downwards, as indicated in the
accompanying diagram. Tighten
the four screws for added stability.

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.
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 with 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.

48 V/0.2 A).
that the external power adapter
(includes power cords
and plug assemblies) provided with the unit is certified and

Grounding the Moxa OnCell G3150A-LTE
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. The
minimum cross-sectional area of the grounding conductor should be
equal to that of the input cable.
his product is intended to be mounted on a well-grounded
mounting surface, such as a metal panel. The potential difference
between the two ground potentials must be zero. If the potential
difference is NOT zero, the product could be permanently
damaged.

Wiring the Relay Contact
The OnCell G3150A-LTE has one relay output, which consists of the two
contacts of the terminal block on the OnCell G3150A-LTE’s top panel.
Refer to the Specifications
section for detailed electrical requirement. The
relay contacts are used to indicate user-configured events. The two wires
attached to the relay contacts form an open circuit when a
user-configured event is triggered. If a user-configured event does not
occur, the relay circuit will be closed.

Wiring the Digital Inputs
The OnCell G3150A-LTE has two sets of digital inputs—DI1 and DI2. Each
DI comprises of two contacts on the 6-pin terminal block connector
located on the top panel of the OnCell G3150A-LTE. Refer to the
Specifications
section for detailed information on isolated digital input
definition.
Communication Connections
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the front panel of the OnCell
G3150A-LTE are used to connect to Ethernet-enabled devices.
Pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type)
ports are shown below:
Serial DB9 Connection
The OnCell G3150A-LTE has one DB9 male port that supports RS-232,
RS-485-4W, RS-485-2W, and RS-422. The pin assignments are shown in
the table below:
DB9 Male
DSR – – 7 TRS – – 8 CTS – – 9 – – –
RS-232 Connection
The OnCell G3150A-LTE has one RS-232 (8-pin RJ45) console port
located on the front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25
cable to connect the Moxa OnCell G3150A-LTE’s console port to your PC’s
COM port. You may then use a console terminal program to access the
OnCell G3150A-LTE for configuring the console configuration.
