Installation and Configuration

Before installing the WDR-3124A, 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 WDR-3124A has a default IP address that you must use when connecting to the device for the first time.

Step 1: Insert a SIM card and turn on the WDR-3124A
Insert one or two 2G/3G SIM cards into the SIM slots located on the bottom of the WDR-3124A. Then, turn on the WDR-3124A by connecting a power terminal block to a DC power source (12 to 48 VDC).

Step 2: Connect the WDR-3124A to a notebook or PC
Since the WDR-3124A supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or crossover cable to connect the WDR-3124A to a computer. If the LED indicator on the WDR-3124A’s LAN port lights up, it means a connection has been established.

Step 3: Set up the computer’s IP address
Set an IP address on the same subnet as the WDR-3124A. Since the WDR-3124A’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 WDR-3124A
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 user name and password. For first-time configuration, enter the default user name and password and then click Login.
User name: admin
Password: root

ATTENTION

For security reasons, we strongly recommend changing the password. To do so, select Maintenance > Username/Password, and then follow the on-screen instructions.

NOTE: For the change to take effect, you must click Save Configuration to save the changes, and restart (clicking the Save and Restart buttons will save all changes).

DIN-Rail Mounting

DIN-Rail Kit Dimensions:

Unit = mm (inch)

The DIN-rail kit is attached to the back panel of the WDR-3124A. Mount the WDR-3124A on corrosion-free mounting rails that meet the EN 60715 standard.

Installation

STEP 1: Insert the upper lip of the DIN rail into the DIN-rail mounting kit.
STEP 2: Press the WDR-3124A towards the DIN rail until it snaps into place.

Removal

STEP 1: Pull down the latch on the mounting kit using a screwdriver.
STEP 2: Slightly pull the WDR-3124A forward.
STEP 3: Lift up to remove the WDR-3124A from the DIN rail.

Wall Mounting (optional)

For some applications, it may be more convenient to mount the WDR-3124A to a wall.

Wall-mount Kit Dimensions:

STEP 1:
Remove the aluminum DIN-rail attachment plate from the WDR-3124A, and then attach the wall mount plates with M3 screws, as shown in the adjacent diagram.
Wall Mounting

STEP 2:
Mounting the WDR-3124A to a wall requires 4 screws. Use the WDR-3124A 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 screw into one of the keyhole shaped apertures of the Wall Mounting Plates before it is screwed into 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, and then slide the WDR- 3124A downwards, as indicated in the accompanying diagram. Tighten the four screws for added stability.

WARNING

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

Wiring Requirements

WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your WDR- 3124A.

WARNING
Safety First!
Calculate the maximum possible current 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 items:

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 (12V/0.7A to 48V/0.2A).

ATTENTION
Make sure that the external power adapter (includes power cords and plug assemblies) provided with the unit is certified and suitable for use in your country.

Grounding the WDR-3124A

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.

Wiring the Redundant Power Inputs

The top two pairs of contacts of the 10-contact terminal block connector on the WDR-3124A’s top panel are used for the WDR-3124A’s two DC inputs. Top and front views of the terminal block connector are shown here.

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 WDR-3124A’s top panel.

ATTENTION
Before connecting the WDR-3124A to the DC power inputs, make sure that the DC power source voltage is stable.

Wiring the Relay Contact

The WDR-3124A has one relay output, which consists of the two contacts of the terminal block on the WDR-3124A’s top panel. Refer to the Specification 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 WDR-3124A has two sets of digital inputs—DI1 and DI2. Each DI comprises two contacts of the 6-pin terminal block connector on the WDR-3124A’s top panel. Refer to the Specification section for detailed information on isolated digital input definition.
