Overview
The IEX-402-VDSL2 is an industrial-managed Ethernet extender for extending up
to 3 km of LAN segments over twisted-pair copper wires at data rates of up to
100 Mbps using the VDSL2 standard. The Ethernet extender is designed with one
10/100BaseT(X) and one DSL port.
The IEX-402-VDSL2 series is designed for use in harsh operating environments.
The DIN-rail mount, wide operating temperature range (-40 to 75°C), and dual
power input make it ideal for installation in industrial applications.
To simplify configuration, the device will set one as CO and the other as CPE
with auto CO/CPE negotiation (factory default setting). Advanced management
and monitoring functionalities through NMS, including a virtual panel, improve
the user experience for quick troubleshooting.

Mounting Dimensions – unit = mm (inches)
DIN Rail Mounting
The aluminum DIN rail attachment plate should already be fixed to the back panel of the IEX-402-VDSL2 when you take it out of the box. If you need to reattach the DIN rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the following figures.
STEP 1: Insert the top of the DIN rail into the slot just below the stiff metal spring.
STEP 2: The DIN rail attachment unit will snap into place as shown below.
To remove the Moxa Ethernet Extender from the DIN rail, simply reverse steps 1 and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the IEX-402-VDSL2
on the wall, as shown in the following figures.
STEP 1: Remove the aluminum DIN rail attachment plate from the
IEX-402-VDSL2 rear panel, and then attach the wall mount plates as shown in
the diagram as shown below. 
STEP 2: Mounting the IEX-402-VDSL2 on the wall requires 4 screws. Use the switch, 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 3.5mm in diameter, as shown in the figure at the right.
NOTE Before tightening the screws into the wall, make sure the screw head and shank size are suitable by inserting the screw into one of the keyhole- shaped apertures of the wall mounting plates.
Do not tighten the screws completely—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.
STEP 3: Once the screws are fixed into the wall, insert the four screw
heads through the large parts of the keyhole-shaped apertures, and then slide
the IEX-402-VDSL2 downwards, as indicated. Tighten the four screws for added
stability.

Wiring Requirement
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your Moxa
Ethernet Extender.
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.
If the current goes above the maximum ratings, the wiring could overheat,
causing serious damage to your equipment
Be sure to read and follow these important 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 through 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.
-
When necessary, you should label the wiring to all devices in the system.
Grounding the Ethernet Extender
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 onto a well-grounded mounting surface,
such as a metal panel.
Wiring the Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power sources. If
one power source fails, the other live source acts as a backup and
automatically supplies the IEX-402-VDSL2 with power.
The two 2-contact terminal block connectors on the IEX’s top panel are used
for IEX’s two DC power inputs. The top and front views of the terminal block
connectors are shown here. 
ATTENTION
Before connecting the IEX-402-VDSL2 to the DC power inputs, make sure the DC
power source voltage is stable.
Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the IEX-402-VDSL2’s
10/100BaseTX ports to any kind of Ethernet device, without needing to pay
attention to the type of Ethernet cable being used for the connection. This
means that you can use either a straight-through cable or cross-over cable to
connect the IEX-402-VDSL2 to Ethernet devices.
Communication Connections
IEX-402-VDSL2 models have one 10/100BaseT(x) Ethernet port, and one DSL port.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the IEX’s front panel are used to connect
to Ethernet-enabled devices.
Next, we show pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-
type) ports and also show cable wiring diagrams for straight-through and
cross-over Ethernet cables.

DSL Port Connection
The DSL port located on the IEX-402-VDSL2 has two connection options.
One is the RJ45/RJ11 connector interface (2-wire on pin 4 and pin 5), the
other is the screw detachable interface. Pinouts are illustrated below.

Wiring the 2-Contact DSL Port
The 2-contact terminal block connectors on the IEX’s top panel are used for
the IEX’s DSL port wiring. Top and front views of the terminal block
connectors are shown here.
Step 1: Insert the wires into the Ring/Tip terminals
Step 2: To keep the 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 IEX’s top panel.
RS-232 Console Port Connection
The IEX-402-VDSL2 has one RS-232 (10-pin RJ45) console port, located on the
top panel. Use either an RJ45-to-DB9 (see the cable following wiring diagrams)
to connect the IEX-402-VDSL2‘s console port to your PC’s COM port.
You may then use console terminal software, such as Moxa PComm Terminal
Emulator, to access the IEX-402-VDSL2’S serial console.

Restore Factory Defaults Button
Press and hold the Reset button for 5 seconds to load the factory default settings. Use a pointed object, such as a straightened paper clip or toothpick, to depress the Reset button. This will cause the STATE LED to blink once a second. After depressing the button for 5 continuous seconds, the STATE LED will start to blink rapidly. This indicates that factory default settings have been loaded and you can release the reset button.
NOTE Do NOT power off the Ethernet extender when loading default settings.
DIP Switches Settings
The IEX-402-VDSL2 series provides 3 hardware DIP switches for advanced
configurations, including CO/CPE, SPEED/SNR, and STD/INP. 
-
CO/CPE DIP Switch:
The default configuration is CO.
Designate the extender as a CO (central office) or CPE (customer premises equipment) device. -
SPEED/SNR DIP Switch:
The default configuration is SPEED.
Select the type of DSL connection status, SPEED or SNR, to be displayed on the DSL SPEED/SNR LED on the front panel of the device. -
STD/INP DIP Switch:
The default configuration is STD.
Select STD (standard) mode or INP (impulse noise protection) mode for the DSL connection.
STD mode: Direct data transmission with less than 2 ms latency
INP mode: Data transmission with impulse noise protection. Latency is under 8 ms with 500μs interleave DMT.
NOTE Reboot the device after reconfiguration of CO/CPE and STD/INP DIP switch settings.
Auto-Negotiation Mode
The VDSL2 Ethernet extenders operate in pairs. One of the units needs to be
configured as a CO device and the other as a CPE device. By factory default,
IEX-402-VDSL2 is configured as a CO device.
To make configuration easier, the IEX-402-VDSL2 supports auto CO/CPE
negotiation. When both extenders have the CO/CPE DIP switch set as CO (factory
default setting), auto CO/CPE negotiation will automatically assign one device
as the CO and the other device as the CPE.
