Hardware Introduction
The Industrial Gigabit Ethernet VDSL2 Extender MS657023X
allows the transmission of Gigabit Ethernet data over simple
twisted-pair lines. Therefore Ethernet signals are converted
into VDSL2 signals and vice versa. The extender is used per
pair. One device has to be configured as master, the other
one as remote unit. The data rate depends on the transmis-
sion distance and the quality of the cable.
Bottom Interface
On the bottom side the following interfaces are placed:
RJ-45 connector for 10/100/1000Base-T Ethernet
RJ-45 connector for VDSL2
LEDs for Ethernet, VDSL and power
DIP switch for easy configuration
Both RJ-45 ports are intended for the use of shielded and
unshielded cables.
LAN Port
The device is equipped with a 10/100/1000Base-T Ethernet
port with RJ-45 connector which supports auto-negotiation
and auto-crossing.
VDSL2 Port
For the VDSL interface a RJ-45 connector is used too. But
only pin 4 and 5 are used. Therefore a RJ-11 could be used
instead. However the use of high quality RJ-45 connectors is
recommended. For 2-wire lines Microsens offers a RJ-45
adapter with screw terminal. This adapter eliminates the
need of crimped connector.
LED Interface
An extended LED interface gives detailed information about
the device status. Their color is always green.
PWR LED
A static green LED indicates that the device is powered.
VDSL LEDs
RT LED: The RT LED indicates the configured device mode.
“ON” means that the device is configured as remote unit.
LNK LED: This LED informs about the VDSL link. The LED is
on if a valid link is established. Slow blinking indicates that
the device is in learning mode. Fast blinking indicates data
transmission. The learning mode should be finished after
around 90 seconds. Otherwise the connection should be
checked.
LEDs for Ethernet Port
For the Ethernet port 3 LEDs are used. They are indicating
link speed and data transmission. Only the LED for the es-
tablished link speed is on. Blinking indicates data transmis-
sion.

Remote Unit (RT) will always follow the setting
of Master Unit (OT). When the unit operates in
RT Mode, DIP switches 2, 3 and 4 have no func-
tions.
Power Interface / Earth Terminal
On the top side, the earth terminal (M4 screw) and the power
interface with screw terminal plug are placed. Connect the
earth terminal to the protective earthing conductor of the
buildings installation.
The power interface supports 12 and 24 VDC input voltages.
Insert the positive and negative wires into V+ and V- contact
on the terminal block and tighten the wire-clamp screws to
prevent the wires from being loosened. The total power con-
sumption is approximately 4.5 W.
