2 AVDS - Getting Started
2 Getting Started
We recommend that you:
• Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
• Review the contents of this user manual
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
• Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
• Do not secure the cables in tight bundles or roll the slack into tight coils
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
• Position your Kramer AVDS away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
Place cables away from fluorescent lights, air conditioners, and
machines that are likely to generate electrical noise.
Note! In the AVDS system the CAT 5 cables carry electrical power.
Therefore do NOT connect them to any other device. To avoid this we
recommend you attach the stickers provided to the ends of each CAT
5 cable.

Warning:
Do not connect any of the VDS products to the AVDS
system. Damage will occur.
3.1 The Multi-Functional AVDS System
You can use the AVDS system in the following ways:
Without the Control Unit
The AVDS system constantly broadcasts a computer screen with audio to all
remote monitors/speakers.
With the Control Unit
• Broadcast a computer screen with audio to all remote monitors/speakers
• Darken all remote screens (audio broadcast is unaffected)
• Release the remote screens to allow local monitor viewing (when remote
computers are connected)
The screen dark function is useful when carrying out maintenance, changing the
broadcast program or in a classroom environment to grab students’ attention.

3.2 Remote and Power Remote Units
Note! Any reference to Remote units refers to both Remote and
Power Remote units unless stated otherwise.
Both types of Remote units can be up to 110m (360ft) away from the Broadcaster.
The two Remote unit types differ as follows:
The Remote units:
• Receive power from the connected shielded CAT 5 FTP cable
• Must be connected with shielded CAT 5 FTP cables with metal RJ-45
connectors that have the drain wire soldered to them
The Power Remote units:
• Need a separate power supply (provided)
• Can be connected with shielded CAT 5 FTP or CAT 5 UTP cables
• Produce high-quality audio signals

3.3 Remote Long Units
AVDS RL transmits full HD video and mono audio to a plasma/LCD screen located
up to 250m (825ft) away over CAT 5/6/7 cable.
The AVDS RL displays rich multimedia content to a single screen in real-time, over
a long distance (with skew correction capability), without degradation to video or
sound quality.
Figures 4, 5, 6 and 7 illustrate the Remote units.

Figure 9 illustrates the AVDS cables with their connections.
Figure 9 AVDS Cables
4.1 Connecting an Optional Remote Computer
You have the option to connect the Remote units (not a Remote Long unit) to a
computer, which can be worked on locally. To do so you need to connect Video
and Audio cables between the Remote unit and a computer. Remote Video and
Audio cables are available for order.
4.2 Connecting the CAT 5 Cables
AVDS works with CAT 5/5e/6/7 data solid wire cabling.
Note! Connect the CAT 5 cables to the Broadcaster and Line Splitter
units when the units are powered off. We recommend that you connect
the CAT 5 cables BEFORE connecting the power supply.
4.3 Connecting the Remote Long Unit
Connect a CAT 5/6/7 cable as follows:
• Connect the CAT 5/6/7 cable - up to a distance of 250m (825ft) - to the
System port of the Remote Long and the System port of the
Transmitter/Broadcaster or Line Splitter. See
Figure 4 above
4.4 Connecting the Screens
• Connect the screen/display to the Remote/Long Video port using the
screen’s video cable
• Connect the screen/speakers to the Remote/Long Audio port using the

5 Expanding the AVDS System
You can expand the AVDS system to 512 Remote units by having up to two levels
of Line Splitters. Each Line Splitter on level 1 can have eight Remote units or Line
Splitters connected to it. Each Line Splitter on level 2 can connect to eight Remote
units. (
Figure 10 illustrates the configuration diagram).
Figure 10 illustrates the expanded AVDS configuration without optional computers
connected to the Remote units. The connections are minus the Remote Video and
Audio cables.

Once connected the AVDS system broadcasts to all remote monitors/speakers.
6.1 The Control Unit
Figure 13 illustrates the Control unit.
Figure 13 Control Unit
The control unit performs the following functions:
Master to All
Press the MASTER TO ALL button to send the broadcaster’s screen with audio to
all remote monitors /speakers. The LED above the button lights up.
Press the button again to release the remote monitors/speakers, allowing local
monitor viewing (when remote computers are connected).
Dark All
Press the DARK ALL button to darken all remote screens. The LED above the
button lights up. (This does not affect audio broadcasting).
Press the button again to release the remote monitors.
Adjusting the Picture Quality
When the picture needs adjusting, tune the picture as follows:
For the Remote unit
• Use a small screwdriver to turn the Picture adjuster on the Remote unit to

adjust the picture quality
For the Remote Long unit
• To enter the tuning mode, hold down the Remote Long’s EQ/SKEW knob
(see Figure 8
) for 4 seconds, the RGB LED turns red. During the tuning
procedure the RGB LED goes through a cycle of six different colors, with
each color representing a different parameter to tune
The color order is: Red > Green > Blue > White > Orange.
The colors mean the following:
• Red, green and blue – red, green and blue skew correction
• White – peak correction
• Orange – gain correction
To adjust the picture for each color, rotate the knob. When the RGB LED flashes it
means that the maximum or minimum tuning parameter has been reached.
Once the tuning is satisfactory, press the knob to save the adjustment and move
to the next color. By not
pressing the knob, adjustments done for the currently lit
color, is not saved and the unit exits the tuning mode after approximately 13
seconds of inactivity.
Exiting Tuning Mode
The unit automatically exits the tuning mode either at the end of the color cycle -
after pressing and saving the orange color adjustment - or (as already mentioned)
at any point in the process after not touching the knob for approximately 13
seconds. The LED turns off.
