Quick start checklist for a typical installation
To create a successful installation, the PixelArt system requires a combination of
mechanical, electrical and software configurations. This quick start checklist runs
through the general order of tasks required for a typical installation:
1 Mount the PixelArt fixtures using standard or custom brackets. see page 3
2 Make daisy-chain power and signal connections between the PixelArt fixtures and also connect the
main signal link from the Video Mapper (V-PORT MAIN socket) to port A of the first PixelArt fixture. see pages 4 & 5
3 Set up a network link between the Video Mapper and the configuration computer. see page 6
4 On the Video Mapper, connect your video source to the appropriate video input
socket (DVI In or VGA In) and attach a DVI monitor to the DVI Out socket. see page 7
5 Power up the PixelArt fixtures, the Video Mapper, the DVI monitor, the video source
and/or the computer.
6 On the computer, run the PixelArt Setup Utility and set the ‘Auto-Number Fixtures’ option to ‘On’
for just five seconds and then switch it ‘Off’. see page 9
7 In the PixelArt Setup Utility, use the ‘Video Input Properties’ (within the ‘Video Mapper’ menu)
option to select the appropriate video input source and define the required video crop area. see page 10
8 In the PixelArt Setup Utility, optionally select the ‘Fixture Discovery’ tab and click the ‘Discover Fixtures’
button to determine the current arrangement of the connected PixelArt fixtures. see page 10
9 In the PixelArt Setup Utility, select the ‘Fixture Mapping’ tab and where necessary, arrange the
PixelArt fixture positions and orientations within the video space to match their physical locations.
When ready, click the Transmit All button to transfer your new mapping details to the
Video Mapper and fixtures. see page 10
10 In the PixelArt Setup Utility, when your configuration is complete, you are strongly recommended to
save the details so that they are immediately available in the future. From the File menu, select the
‘Save Fixture Mapping As’ option to create a .csv file containing your configuration. see page 10
11 On the Video Mapper, when all settings have been made, use the ‘Configuration’ > ‘Save’ option
to ensure that the unit begins using the same settings automatically at every power up. see page 8
12 Connect the standby link (if used) from the last PixelArt fixture to the V-PORT STANDBY socket
of the Video Mapper. see page 4
The PixelArt fixtures should now be displaying the portion of the video source as defined by the
crop area settings. If they are not, then please refer to the Troubleshooting section. see page 14

Use a safety wire
Ensure that all PixelArt Battens
mounted off-ground are protected
using a secure safety wire (rated
to at least 15Kg, 33lbs) through
the eyelet situated adjacent to the
connection panel.
Supplied Omega brackets
Each PixelArt Batten is supplied with two ‘Omega’
brackets (plus fixings) which attach at the top and
bottom of the rear panel.
For each bracket
1 Insert the two screws into the sockets at the top
left and bottom right holes of the fixing area.
Leave them loose.
2 Securely fit the required clamps to each of the
omega brackets using the supplied bolts, washers and Nyloc® nuts.
3 Offer the bracket to the screws so that the
curved slots engage, then rotate the bracket
anti-clockwise. Tighten the screws.
4 Insert the two twist lock bolts into the top right
and bottom left holes and twist them clockwise
to lock the bracket in place.
5 Double check that each bracket is secure and
use a safety wire (see below).
Optional U-brackets
Optional U-brackets allow greater
tilted angles for PixelArt Battens.
For each bracket
1 Place the supplied fibre washers
between the U-bracket and the
side holes of the PixelArt Batten.
2 Place the metal washers onto the
screws and insert them through the
bracket and the fibre washers into
the side holes.
3 Tighten the screws and double
check that the bracket is secure.
4 Use a safety wire (see left).
IMPORTANT: If a fall is arrested by
the safety chain, the fixture must be
returned to the point of purchase for
checking before it is re-used.

PixelArt Batten signal cabling
• Industry standard Category 5e or 6 (CAT 5e or CAT 6) twisted pair network cable terminated at either
end with standard RJ45 connectors or Neutrik® EtherCon® NE8MC (for more robust linking). Either crossover or straight wired cables may be used for each link - every batten configures the signals accordingly.
• Maximum length of 100 metres (328 feet) between any two battens (or between the Video Mapper and a
batten). Every PixelArt Batten reconditions the signal before transmitting it to the next.
• A maximum of 100 PixelArt fixtures are permissible within a single installation.
•
IMPORTANT: Do not connect ANY PixelArt Batten cabling to an Ethernet network. Such an interconnection
will not cause damage but will result in both the PixelArt system and the network functioning incorrectly.

Standby cabling
You have the option to run a link cable from the last PixelArt fixture
back to the STANDBY port of the Video Mapper. This provides a
failsafe loop against link cable failure. In such an occurrence, the
system will automatically recognise the loss of signal and re-route
from the other direction up to the lost cable. The battens will all
reconfigure themselves accordingly and operate around the failure
with no loss of output on either side of the break.
IMPORTANT: When setting up a new
installation, do not connect the standby
cable to the Video Mapper until the
PixelArt fixtures have been taken out
of auto-numbering mode. Otherwise
the battens will incorrectly begin auto
numbering themselves from both ends
of the installation.

Used to link a computer to the Video
Mapper, primarily for initial configuration
purposes.
You can either connect your computer directly to the
Video Mapper or indirectly via a network router/hub.
Use CAT5e or CAT6 cable (see crossover note above).
Depending on its configuration, the Video Mapper
will either attempt to automatically find itself a suitable network address or will use a pre-configured
setting (determined by ‘Network Settings’ within the
Video Mapper menu - see page 8).
During automatic searches, the Video Mapper will
try to configure itself according to the connected
network (using DHCP or Dynamic Host Configuration
Protocol). In automatic mode, if no other devices are
discovered, the Video Mapper will timeout and use a
default address and subnet mask, usually: 2.0.0.20
and 255.0.0.0 respectively.
Note: The search will take longer if no network is
connected.

Video input
IMPORTANT: To achieve best
quality results from PixelArt
fixtures, use only digital DVI
video inputs wherever possible.
Analogue VGA input
Digital DVI/D input
Video input resolution and frequency
The link between the Video Mapper and the PixelArt
fixtures has a maximum bandwidth of 120,000 pixels at
25Hz (frames per second). This equates to a quarter of an
800 x 600 video input or just under half of a 640 x 480
input. The actual portion of the video input that is sent to
the PixelArt fixtures is determined using the Crop Area settings within the PixelArt Setup Utility (see page 9).
The Video Mapper automatically takes every third frame
from the video input. Therefore, the optimum video input
resolution is 75Hz (in order to achieve an ideal 25Hz (25
frames per second) output to the PixelArt fixtures).
Supported frequencies
The following frequencies are supported by the Video
Mapper:
640x480 @ 75Hz
720x576 @ 75Hz
800x600 @ 75Hz

Video Mapper startup
As soon as power is applied to the Video Mapper, it will either attempt to
automatically find itself a suitable network address or will use a pre-configured
setting as determined by ‘Network Settings > Network Setup > Set Network
Mode’.
During automatic searches, the Video Mapper will try to configure itself according to the connected network (using DHCP or Dynamic Host Configuration Proto-
col). In automatic mode, if no other devices are discovered, the Video Mapper
will timeout and use a default address and subnet mask, usually: 2.0.0.20 and
255.0.0.0 respectively.
You can preset a network address and subnet mask using ‘Network Settings >
Network Setup > Set IP Address / Set Subnet Mask’.
Note: The automatic search will take longer if no network is connected.

PixelArt Setup Utility
The PixelArt Setup Utility is used during initial configuration and can be run on any Windows® XP or Vista -based computer (with Java6 or
later) or any Apple Mac (with Java 5 or later) that is network linked to the Video Mapper.
Video Mapper communication
Check that the network address shown in the Video Mapper IP address section matches the address shown in the startup display of
the Video Mapper. If the network addresses do not match or there
is no address shown in the section, then there may be a communication problem. Please see the Troubleshooting section on page 14
for details.

Auto-Numbering fixtures
When beginning a new installation, it is vital to briefly place the
connected PixelArt fixtures into auto-numbering mode so that they
can assign themselves unique fixture numbers, according to their positions within the daisy chain cable link. Once complete you do not
need to auto number the PixelArt fixtures again, unless any fixtures
are added, removed or moved.
Note: It is important that the Auto-Number Fixtures option is switched
Off before the standby link is made from the final PixelArt fixture to
the Video Mapper.
To auto-number the PixelArt fixtures
1 In the lower left corner of the PixelArt Setup Utility window, in the
‘Auto-Number Fixtures’ section, click the ‘On’ option.
2 After five seconds, click the ‘Off’ option.
2
Confirming the source video input
The Video Mapper provides a choice of two video inputs: DVI digital
or VGA analogue. Of the two input types, the DVI option provides a
much greater image quality. You need to confirm to the Video Mapper which input is being used.
To confirm the source video input
1 In the PixelArt Setup Utility window, click the ‘Video Mapper’
menu and select the ‘Video Input Properties’ option to display the
Video Input Setup window.
2 In the Video Input section of the window, select either the DVI or
the RGB/VGA option, as appropriate.
If you select the RGB/VGA option, then you will also need to
confirm the resolution of the video source. Click the down arrow
of the Resolution box and select the appropriate setting.
3 When the appropriate settings have been made, click the Set
button to send the data to the Video Mapper.
3
Defining the video crop area
The PixelArt fixtures display a portion of the total input video source
and that portion is defined by the crop area. Once defined, all PixelArt fixture coordinates are determined relative to the top left hand
corner of the crop area.
Note: The Video Mapper provides a crosshair tool to assist you to
relate positions on the output video monitor (and the PixelArt fixtures)
with pixel coordinates - see the next page for details Ü
To define the crop area
1 In the PixelArt Setup Utility window, click the ‘Video Mapper’
menu and select the ‘Video Input Properties’ option to display a
dialog box (shown on page 9).
2 In the ‘Crop Area’ section, enter the required position of the top
left corner of the crop area using the x and y fields. In each case,
you are entering the number of pixels across (x) and down (y)
from the top left corner of the total video space area (i.e. 800 x
600; 640 x 480, etc.).
3 Now define the size of the crop area using the Width and Height
fields. Again, these are measured in pixels and the total area
must not exceed 120,000, (e.g. width = 400 x height = 300)
which is the upper limit that can be sent to the PixelArt fixtures.
Note: Ensure that your combined crop area size and position
settings result in the crop area lying within the overall video input
space, i.e. so that a portion of the crop area does not overhang
any of the video space boundaries.
4 When the appropriate values have been entered, click the Set
button to send the data to the Video Mapper. On the DVI monitor
you will see the green outlined crop area change within the total
video space to reflect your values. This is now the screen area
that will be sent to the PixelArt fixtures.
4
Fixture mapping
Thanks to the flexible manner in which the PixelArt fixtures are designated, you can configure any PixelArt fixture to occupy any position
(and any 90 degree rotation) within the video space defined by the
crop area. This is called fixture mapping and is a key feature of the
PixelArt system. There are two main ways to determine fixture mapping:
• By using just the PixelArt Setup Utility, or
• By using a spreadsheet and the PixelArt Setup Utility.
See also:
Fixture orientation and positioning pages 12 and 13
To perform a fixture discovery
When beginning a new installation, it is common, but not essential to discover the current configuration of all connected PixelArt
fixtures. From this starting point it can be more straightforward to
adjust the configuration to suit your required layout, particularly if
the PixelArt fixtures have been wired in a logical sequence.
1 In the PixelArt Setup Utility window, click the ‘Fixture Discovery’
tab.
2 Click the ‘Discover Fixtures’ button. Within a short while, the x,
y and orientation coordinates for each PixelArt fixture will be
updated within the list.
To map fixtures using only the PixelArt Setup Utility
1 In the PixelArt Setup Utility window, click the ‘Fixture Mapping’
tab.
2 For each fixture entry, click your cursor in the required x, y or
Orientation field and edit the entry, as necessary. Press your
keyboard’s Enter key to fix the new value.
3 Repeat step 2 for each entry that needs to be changed.
4 When all changes have been made, either click the ‘Transmit
All’ button or highlight one or more fixture entries and click the
‘Transmit Selection’ button.
To map fixtures using a spreadsheet and the utility
1 Use a spreadsheet such as Microsoft Excel to create a simple
file with four columns and as many rows as there are PixelArt
fixtures. From left to right the columns represent: Fixture number,
x, y and orientation.
Alternatively, in the PixelArt Setup Utility, save the current discov
ered fixtures to a ‘.csv’ file (using the ‘Save Discovered Fixture
Map As’ option in the File menu), then open that file within your
spreadsheet and use it as a template.
2 Once your mapping details are complete, save the file with a
‘.csv’ file ending.
3 In the PixelArt Setup Utility, open the saved file using the ‘Load

Save settings in Video Mapper flash memory
Once all settings have been made and sent to the Video Mapper,
you need to ensure that they are also transferred to the Video Mapper’s non-volatile flash memory so they are instantly available at the
next power up (and can be used independently of the computer).
To save settings in Video Mapper non-volatile memory
You can do this in two ways, either:
• In the PixelArt Setup Utility window, click the ‘Video Mapper’
menu and select the ‘Save Current Setup to Video Mapper’ option to transfer all configuration details, or
• In the Video Mapper menu, select ‘Configuration’ and select the
‘Save’ option.

Crosshairs, grids and solid colour
The Video Mapper is able to generate and superimpose items over the source video input to assist you during configuration. As well as being able to apply solid colours to the whole video space, you will find the crosshairs particularly useful when defining the crop area and the
grid invaluable when initially testing the fixture mapping.
Using crosshairs when defining the crop area
When configuring a new installation it
is necessary to define the size and position of the crop area (within the total
video space) that will form the region
displayed by the PixelArt fixtures.
The Video Mapper provides a set
of crosshairs to assist in locating the
required coordinates of the crop area.
The crosshairs are superimposed on the
video input as seen on the connected
DVI video monitor and also, when they
enter the crop area, on any connected
PixelArt fixtures that are mapped into
the same area.
You have the choice of viewing crosshair coordinates relative to the entire
video space origin (absolute) or relative to the origin of the crop area. The
former is useful when defining the crop
area, the latter is more useful when testing/locating areas once the crop area
has been fully defined.
The current x or y coordinates (absolute or crop area) of the crosshairs are
shown on the Video Mapper display
and these can be used directly within
the PixelArt Setup Utility.
To use the crosshairs
1 On the Video Mapper, enter the
Pattern Tools menu and select the
‘Crosshair On/Off’ option. Choose
the ‘On’ setting.
Note: You can also change the
colour for the crosshairs.
2 Select the ‘Crosshair Area’ option and choose either ‘Absolute’ or ‘Crop Area 1’ as required.
3 Select the ‘Crosshair X’ or ‘Crosshair Y’ option, as appropriate, and increase or decrease the position value until the crosshair arrives at
the required position, as seen on the monitor and possibly the PixelArt fixtures.
4 Read off the value shown on the display and use this when defining the crop area or locating a section within the crop area.
5 Repeat steps 3 and 4 for the other crosshair.
Using the grid when fixture mapping
The grid feature provided by the Video Mapper is useful when initially mapping
fixtures or when testing fixtures because it can quickly highlight any fixtures that
have been mapped or mounted incorrectly.
To use the grid
1 On the Video Mapper, enter the Video Settings menu and select the Input
Source option. Choose the ‘Pattern Generator’ option.
2 Now enter the Pattern Tools menu and select the ‘Grid On/Off’ option.
Choose the ‘On’ setting.
Note: You can also change the colour for the grid.
3 Select the ‘Grid Pitch’ option and adjust the grid spacing from 0 to 20. If
the PixelArt fixtures are correctly mapped and positioned, you should see a
contiguous grid across all fixtures.
Note: When you have finished with the grid, you need to change the input
source back to either ‘DVI port’ or ‘VGA port’ within the ‘Video Settings’ >
‘Input Source’ menu.

PixelArt fixture orientation
You can physically arrange each PixelArt
fixture in any of four rotational positions:
0, 90, 180 or 270 degrees, going anticlockwise relative to the horizontal plane.
To match the physical arrangements, you
need to inform the PixelArt fixtures themselves (via the PixelArt Setup Utility and
the Video Mapper) which way they are
positioned.
Each PixelArt fixture maintains a logical
origin point at its top left hand corner, irrespective of its rotation. This is to simplify
fixture positioning information and also to
ensure that the video image remains true,
regardless of how each PixelArt fixture is
arranged.
In the representations shown here, the
power cables are used to indicate the
direction of the fixture.

Orienting PixelArt fixtures
You can set the orientation for each PixelArt fixture using either:
• The Fixture Mapping tab of the PixelArt Setup Utility,
or
• A spreadsheet (such as Microsoft
®
Excel®) to create a (.csv)
file that can be loaded into the PixelArt Setup Utility.
See page 13 for details.

PixelArt fixture positioning
You can place each PixelArt fixture
anywhere within the video space
defined by the crop area.
Each PixelArt fixture’s position
within the video space is totally
independent of its location in the
control cable daisy chain, although
it is common for the two to coincide.
Three values are required to position a PixelArt fixture within the
video space:
• a horizontal
x coordinate
(measured in pixels)
• a vertical
y coordinate
(measured in pixels),
and
• an orientation
(measured in degrees)
The origin point of the video space
is always in the top left hand corner
(of the crop area) and similarly, the
origin point for each PixelArt fixture
is also always in the top left hand
corner, regardless of their respective rotation settings.

Positioning PixelArt fixtures
There are two mains ways to determine the PixelArt fixture positions:
• Use the Fixture Mapping tab
within the PixelArt Setup Utility
or
• Use a spreadsheet (e.g. Microsoft

Troubleshooting
No video output on PixelArt fixtures
• Check that the Blackout option is not active on the Video Mapper.
• Check the video input to the Video Mapper.
• Check that the fixtures are correctly mapped within the crop area.
• Check the indicators at the rear of the PixelArt fixtures for general
illumination and also for error flashes.
• Check the power input fuses and the power feed to the fixtures.
Incorrect or garbled output from one or more PixelArt fixtures
• In the PixelArt Setup Utility on the computer, click the ‘Tools’ menu
and select the ‘Initialise Fixtures’ option.
No communication between computer and Video Mapper
• Check network connection and also network address of computer.
• Disable all network adapters (including wireless and FireWire
links) on the computer except the one that is connected to the
Video Mapper.
• If the Video Mapper is connected directly to the computer (i.e.
not via a network router or hub), ensure that the cable used has
crossover links (i.e. pin 1 to pin 3, pin 2 to pin 6, etc.) rather than
straight through connections (i.e. pin 1 to pin 1, pin 2 to pin 2,
etc.).
• Check that the computer’s firewall is not blocking network access
for the Video Mapper. If so, make an exception for port 6455,
which is used by the Video Mapper. Note: Changes to firewall
settings should only be made by those competent to do so.
Settings keep being lost from the Video Mapper
• After making changes within the Video Mapper menu, be sure to
go to the ‘Configuration’ section and choose the ‘Save’ option.
This will store all settings within non-volatile flash memory. This is
particularly important for network settings as these could affect the
next power up of the Video Mapper.
