Package Checklist

Before installing your OnCell 3120-LTE-1, verify that the package contains the following items. If any of these items is missing or damaged, please contact your customer service representative for assistance.

• 1 OnCell 3120-LTE-1 unit
• 1 DIN-rail mounting kit
• 1 console cable
• Quick installation guide (printed)
• Warranty card

Installation and Configuration

You will need access to a notebook computer or PC equipped with an Ethernet port. The OnCell 3120-LTE-1 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 3120-LTE-1. Refer to the Panel Layout of the OnCell 3120-LTE-1 section below for the location of the ports and sockets.

Step 1: Insert a SIM card and turn on the OnCell 3120-LTE-1

1. Use a screwdriver to loosen the screws and remove the SIM card cover located on the top panel of the OnCell 3120-LTE-1.

2. Insert one or two 4G SIM cards (nano-SIM) into the SIM card slot(s). 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 slot 1 is treated as the primary card. To change the default to SIM2 (the card in slot 2), log in to 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 3120-LTE-1 by connecting a power terminal block to a DC power source (9 to 36 VDC). For details, refer to the Connecting the Power Input section.

4. Reattach the cover.

Step 2: Connect the OnCell 3120-LTE-1 to a notebook or PC
Since the OnCell 3120-LTE-1 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or crossover cable to connect the OnCell 3120-LTE-1 to a computer. See the 10/100BaseT(X) Ethernet Port Connection section below for detailed instructions. If the LAN LED indicator on the OnCell 3120-LTE-1 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 3120-LTE-1. Since the OnCell 3120-LTE-1’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 the subnet mask to 255.255.255.0.
Step 4: Use the web-based manager to configure the OnCell 3120-LTE-1
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.

ATTENTION
For security reasons, we strongly recommend changing the password. To change the password, select Maintenance →Username/Password, and then follow the on- screen instructions.
NOTE You must click the Save Configuration and then the Restart buttons for the configuration changes to take effect.

Device Dimensions

DIN-rail Mounting

The OnCell 3120-LTE-1 Series comes with a DIN-rail kit attached to the back panel. Mount the OnCell 3120-LTE-1 Series on corrosion-free mounting rails that meet the EN 60715 standard.

Installation

STEP 1: Insert the upper lip of the DIN rail into the top hook of the DIN-rail mounting kit.
STEP 2: Press the OnCell 3120-LTE-1 Series towards the DIN rail until it snaps into place.

To remove the OnCell 3120-LTE-1 from the DIN rail, pull down the lever at the bottom of the DIN-rail kit.

Wall Mounting (optional)

For some applications, it may be more convenient to mount the OnCell 3120-LTE-1 to a wall, as illustrated below:

STEP 1:
Remove the aluminum DIN-rail attachment plate from the OnCell 3120-LTE-1, and then attach the wall-mounting plates with M3 screws, as shown in the adjacent diagram.

STEP 2:
Mounting the OnCell 3120-LTE-1 to a wall requires 4 screws. Use the OnCell 3120-LTE-1 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.

NOTE Test the screw head and shank size by inserting the screws into one of the keyhole-shaped apertures of the wall-mounting plates 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-shaped apertures of the mounting kit, and then slide the OnCell 3120-LTE-1 downwards. Tighten the four screws for added stability.

WARNING

• This equipment is intended to be used in a Restricted AccessLocation, such as a dedicated computer room, where access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the fact that the metal chassis ofthe equipment is extremely hot and may cause burns.
• Service persons or users should pay special attention and take special precautions before handling this equipment.
• Only authorized, well-trained professionals should be allowed to access the restricted access location. Access should be controlled by the authority responsible for the location with lock and key or a security identity system.
• External Metal Parts are Hot!! Pay special attention or use special protection before handling this equipment.

Wiring Requirements

WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or wiring the OnCell 3120-LTE-1 device.

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 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.

ATTENTION
This product is intended to be supplied by a Listed Power Unit marked “Class 2” or “LPS” and rated O/P: 9.6 W (12 V/0.78 A to 48 V/0.2 A).

Grounding the Moxa OnCell 3120-LTE-1
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.

ATTENTION
This 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 to zero, the product could be permanently damaged.

SIM Card Socket

The OnCell 3120-LTE-1 comes with two nano-SIM card sockets for cellular communication. The nano-SIM card sockets are located on the top panel along with the antenna connectors. Loosen the screws and remove the cover to access the SIM-card sockets, and then insert the nano-SIM cards into the sockets directly. You will hear a click when the cards are in place. The left socket is for SIM 1 and the right socket is for SIM 2. To remove the cards, push the cards in before releasing them.

Connecting the Power Input

Pinouts for the Power Inputs

Wiring the Power Input

Top and front views of the terminal block connector are shown below:

STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals, and the ground wire into the GND terminal.

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 bottom panel of the OnCell 3120-LTE-1.

ATTENTION
Before connecting the OnCell 3120-LTE-1 to the DC power inputs, make sure that the DC power source voltage is stable.
