across your network. Transmitter and 
receiver extenders can be configured in 
a direct connect or a patch panel 
configuration to best meet the needs of 
your system. Configuration options are 
illustrated on the right, and general 
system information is provided in the 
following section. Proceed to the next 
page for installation instructions.

Cable Extension Rules 
• A maximum extension distance 
of 50 meters is supported with 
single, uninterrupted runs of 
CAT 7a patch or CAT 6 bulk/ 
trunk (not patch) cables at full 
resolution.
• Cable run rules: Overall cable 
runs must be reduced by 5 
meters for each additional 
cable coupling. Run 
specifications may be increased 
by 10 meters when using 
resolutions of 1280 x 1024 or 
lower.
• Patch cables: All patch cables 
must be as short as possible 
and no longer than 2 meters.
NOTE : Prior to completing the 
following steps, ensure your computer is 
turned o.
1. Connecting transmitter 
extender video
For the LongView 4010 
extender, connect a single-link 
digital cable from your 
computer to the DVI-D port on 
the extender. If using the 
LongView 4020 extender, 
connect the digital video link 
cable from the primary video 
port on the computer to the 
bottom (primary) DVI-D port on 
the extender. Then, connect the 
video cable from the secondary 
video port on the computer to 
the top (secondary) DVI-D port 
on the extender.

2. Connecting other transmitter 
extender peripherals
The transmitter extender is 
designed to be powered via a USB 
connection from the computer. 
However, if this is not possible, each 
USB port on the left end of the 
extender can be used for additional 
USB devices. Using a cable no 
longer than 3 meters, plug the USB 
connector into the designated 
transmitter extender port and the 
other end into a USB computer port. 
NOTE : On LongView™ 4020 
extenders, the bottom (primary) USB 
port should connect to the first USB 
computer port. The top (secondary) 
extender USB port is for a second 
USB computer port.
LongView 4020 extenders also 
provide optional bottom 
(primary) and top (secondary) 
audio connections using 3.5 
mm audio cables.
3. Connecting the transmitter 
extender to the receiver 
extender
For a direct connect configuration, 
insert one end of a CAT cable into 
the TO RECEIVER port on the right 
end of the transmitter extender and 
the other end into the TO 
TRANSMITTER port on the receiver 
extender. For the LongView 4020 
extenders, the initial connection 
should be made between the 
bottom ports on the transmitter and 
receiver extenders. If you choose to 
make a secondary connection on 
the LongView 4020 extender, that 
connection should be between the 
top ports. 
In a patch panel configuration, 
insert one end of the CAT cable into 
the TO RECEIVER port on the 
transmitter extender and the other 
end into one of the ports on the 
patch panel. Repeat this process 
with an additional CAT cable from 
the TO TRANSMITTER port on the 
receiver extender. For LongView 
4020 extenders, the initial 
connection should be made from the 
LongView™ 4020 Configuration Shown

bottom extender ports; the 
secondary connection should be 
between the top extender ports.

4. Connecting transmitter 
extender power
If you are unable to power your 
transmitter extender via the 
computer, assemble the power 
adaptor and the power cord. Insert 
one end of the power cord into the 
transmitter extender (LongView 
4020 extender bottom POWER port) 
and plug the other end into an 
appropriate power source. 
NOTE : Squid cables and power 
splitters are not allowed. Use the top

5. Connecting receiver extender 
video
For the LongView™ 4010 extender, 
connect a single-link digital cable 
from your computer to the DVI-D 
port on the extender. If using the 
LongView 4020 extender, connect 
the digital video link cable from the 
primary video port on the computer 
to the bottom (primary) DVI-D port 
on the extender. Then, connect the 
video cable from the secondary 
video port on the computer to the 
top (secondary) DVI-D port on the 
extender.
6. Connecting the keyboard 
and mouse
For the LongView 4010 
extender system, plug one end 
of the keyboard and mouse 
connectors into the receiver 
extender (either USB paired

port) and plug the other end 
into a USB computer port. For the 
LongView™ 4020 receiver extender, 
ensure you plug the keyboard and 
mouse in to the bottom (primary) 
receiver extender USB ports. 
Additional USB devices may be 
plugged in to the top (secondary) 
ports. The paired USB ports on the 
receiver extender are fed separately 
by the corresponding primary and 
secondary USB connections on the 
transmitter extender. Mismatched 
connections will result in 
non-functioning USB devices from 
the receiver extender.
NOTE : The total current 
allowed to be drawn from the 
USB ports is 1.2A. If more power 
is required for USB devices, use 
a powered USB hub. 
7. Connecting audio
For stereo speakers and 
microphones, attach the cables 
to the appropriately labeled receiver 
extender ports. LongView 4020 
extenders provide optional bottom 
(primary) and top (secondary) 
audio connections using 3.5 
mm audio cables.
8. Connecting receiver extender 
power
Assemble the power adaptor 
and the power cord. Insert one 
end of the power cord into the 
POWER port of the receiver 
extender and plug the other 
end into an appropriate power 
source.
9. Powering the extender 
system
Turn on the monitor and the receiver 
extender. If the transmitter extender 
is not powered by the computer, turn 
it on next. Then, turn on the 
computer. There are two LEDs on 
the right end of each extender to 
confirm power status and provide 
feedback. A green LED should be lit 
on both extenders to confirm that 
power is on. On the transmitter 
extenders, a solid yellow LED 
indicates that a valid DVI video 
input signal is being received 
from the computer. This LED 
will not light up if a CAT link 
cable is disconnected. For the 
receiver extenders, a solid yellow 
LED indicates that a valid DVI 
video input signal is being received 
from the transmitter extender. This 
LED will flash twice per second 
when no valid video signal is being 
received. 
NOTE : For LongView 4020 
extenders, these linking ports 
are independent. Failure of one 
link does not aect the video or 
USB status of the other link.
