USB 2.0 (CAT 5) Extension
Max Length 100m

Before you can install the DisplayLink Extender, you need to prepare your site.

1. Determine where the computer is to be located and set up the computer.

2. Determine where you want to locate the Projector(s).

3. If you are using surface cabling, the DisplayLink Extender supports a maximum distance of 100m.

OR

If you are using premise cabling, ensure CAT 5 cabling is installed between the two
locations, with CAT 5 information outlets located near both the computer and the projectors.

Connecting the Computer module to the Projector module

To ensure proper operation, it is recommended that only CAT 5 or better, Unshielded Twisted Pair cabling

be used to connect the Computer module to the Projector module. The cabling must have a straight-through conductor

note

con guration with no crossovers, and must be terminated with 8 conductor RJ45 connectors at both ends. The
combined length of any patch cords using stranded conductors must not exceed 10m.

With Surface Cabling

1. Plug one end of the CAT 5 cabling (not included) into the Link port (RJ45) on the Computer module.

2. Plug the other end of the CAT 5 cabling into the Link port (RJ45) on the Projector module.

With Premise Cabling

1. Plug one end of a CAT 5 patch cord (not included) into the Link port (RJ45) on the Computer module.

2. Plug the other end of the patch cord into the CAT 5 information outlet near the Host computer.

3. Plug one end of the 2nd CAT 5 patch cord (not included) into the Link port (RJ45) on the
Projector module.

4. Plug the other end of the 2nd patch cord into the CAT 5 information outlet near the USB device.

The maximum length of the CAT 5 cable, including patch cords, must not exceed 100 meters. The combined

note

length of any patch cords using stranded conductors must not exceed 10m.

6

Installing the Projector module

1. Place the Projector module near the Projector.

2. Plug the Projector module power cord between the projector module and the projector’s
+5VDC connector.

3. Connect the Projector module to the projector’s DisplayLink connector using the USB cable that was
included with your projector (or a high-quality USB 2.0-compliant USB type-A to mini-B cable, no
more than 2m in length).

Only use the power cord supplied with DisplayLink Extender. Use of substitute power cords may cause permanent
damage to the system and will void the warranty.

Installing the Computer module

1. Place the Computer module near the computer.

2. Plug the USB Type A connector on the Computer into a USB port on the computer.

Device” in the
operating system.

• The projector is
malfunctioning.

• The computer does not
recognise the projector.

• The application software for
the device is not operating.

• The DisplayLink Extender is

malfunctioning.

Technical Glossary

Category 5 (CAT 5) Network Cabling
Category 5 cable is commonly also referred to as CAT 5. This cabling is available in either solid or stranded
twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair). UTP
cables are not surrounded by any shielding making them more susceptible to electromagnetic interference
(EMI). STP cables include shielding over each individual pair of copper wires and provides better protection
against EMI. CAT 5 has been succeeded by CAT 5E cabling which includes better support for high speed
communications and reliability.

RJ45
The Registered Jack (RJ) physical interface is what connects the network cabling (CAT 5) to the Computer
and Projector module. You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2)
for cable termination as the DisplayLink Extender uses all four pairs of the cable. RJ45 connectors are
sometimes also referred to as 8P8C connectors.
