ATTENTION
•
The WDR-3124A is NOT a portable mobile device and should be located at least 20 cm away from the
human body.
•
The WDR-3124A is NOT designed for the general public. A well-trained technician should be enlisted to
ensure safe deployment of WDR-3124A units, and to establish a wireless network.

Device Dimensions
Connecting the Hardware
This section describes how to install SIM cards in the WDR-3124A, mount the WDR-3124A on a DIN-rail or a
wall, and connect the WDR-3124A to a computer for the first time.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device. The
WDR-3124A
should be
secured at one location.
Wiring Caution!
Calculate the maximu
m 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 ratings,
the wiring could overheat, causing serious damage to your equipme
nt.
Temperature Caution!
Be careful when handling the device. When plugged in, the device internal components generate heat, and
consequently the casing may feel hot to the touch.
You should also take note of the following guidelines:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure that the wires are perpendicular at the intersection point.
Note: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•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.
•Keep input wiring and output wiring separate.
•Where necessary, it is advisable to label the wiring to all devices in the system.

WDR-3124A Introduction
1-9
Installing a SIM Card
You can install up to two SIM cards in the WDR-3124A.
To install a SIM card, complete the following steps:
1. Turn off the WDR-3124A.
2. Remove the screw to remove the SIM card slot cover.
3. Install a SIM card into a SIM card slot. Do the following:
a. For SIM 1, orient the gold contacts facing down and the cut-off edge to the left.
b. For SIM 2, orient the gold contacts facing up and the cut-off edge to the right.
4. Install the screw to secure the SIM card slot cover.
To remove a SIM card, complete the following steps:
1. Remove the screw to open the SIM card slot cover.
2. Push down the SIM card tray to unlock it.
3. Rotate the SIM card tray to expose the SIM card slot.
4. Remove the SIM card from the SIM card tray.
Device Mounting
There are two ways to mount the WDR-3124A: DIN-rail mounting and wall mounting.
DIN-Rail Mounting
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.
The following figure shows the DIN-rail kit dimensions (unit = mm (inch)).

WDR-3124A Introduction
1-10
Installation
1. Insert the upper lip of the DIN rail into the DIN-rail mounting kit.
2. Press the WDR-3124A towards the DIN rail until it snaps into place.
Removal
1. Pull down the latch on the mounting kit using a screwdriver.
2. Slightly pull the WDR-3124A forward.
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.
The following figure shows the DIN-rail kit dimensions (unit = mm (inch)).
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.

WDR-3124A Introduction
1-11
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 b
e 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
.
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.
•
External metal parts are hot!! Pay special attention or use special protection before handling.
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.

WDR-3124A Introduction
1-12
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.
1. Insert the negative/positive DC wires into the V-/V+ terminals.
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.
3. Insert the plastic terminal block c
onnector 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.

Serial Connection
The WDR-3124A 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 WDR-3124A’s console port to your PC’s COM port. You may
then use a console terminal program to access the WDR-3124A for console configuration.

ATTENTION
When
the system fails to boot, the LEDs for STATE (Green), FAULT, and WLAN will all light up
simultaneously and blink at one
-
second intervals. This may be due to improper operation or uncontrollable
issues, such as an unexpected shutdown
while updating the firmware. To recover the firmware, refer to
the
“Firmware Recovery”
section in Appendix B.
If the
SIM LED is blinking after the WDR-3124A is powered on for several minutes, check the following:
•
PIN code
•
SIM installation
If the
2G, 3G, and Cellular Signal LEDs are off after the WDR-3124A is powered on for several minutes,
check the following:
•
APN information
•
Username and password
•
Antenna connection
•
Cellular network coverage is available at the current location
Beeper
The beeper emits two short beeps when the system is ready.
Reset Button
You can reboot the WDR-3124A or reset it to factory default settings by pressing the RESET button with a
pointed object (such as an unfolded paper clip).
•System reboot: Hold the RESET button down for less than five seconds and then release.
•Reset to factory default: Hold the RESET button down for more than five seconds or until the STATE LED
starts blinking green. Release the button to reset the WDR-3124A (default IP: 192.168.127.253).
