General set up
1Mount the fixture in the
required position. Brackets
and bolts are supplied to
allow you to mount the unit
in a variety of locations.
2Connect a DMX control
feed (where necessary) and
power to the unit. PixelArc
fixtures are supplied in two
variants: H1 (outdoor) and
H2 (entertainment).
Note: Connections should be made only by a qualified electrician.
H1 (outdoor) connections
• DMX: Remove the end panel next to the conduit fittings. Feed
the DMX-in cable (and DMX-out cable, if necessary) through the
conduit fitting(s) on the front panel. Attach the DMX leads to the
upper connector block, as shown below.
• Power: Feed the power-in cable (12awg conductors) through
one of the two conduit fittings on the rear panel. If you require
a power-out cable, feed it through the other conduit fitting on the
rear panel. Attach the power leads securely to the lower connec-
tor block as shown above.
Note: Ensure that the re-fitted end panel and all conduit cable
fittings have a watertight seal.
H2 (entertainment) connections
• DMX: Connect a DMX lead (XLR 5-pin female) to the input socket
on the end panel of the fixture.
• Power: Attach the supplied bare-wire power cord to a suitably
rated power connector.

Operation modes
The PixelArc fixtures provides a range of operation modes. These
are selected using the MODE section of the control menu:
DMX Allows RGBA control via DMX input. Using the RES
(resolution) option you can determine the number of
DMX channels required: either 3 or 4 channels. Internal
chase effects are not available within this mode.
MANU Provides RGBA colour mixing independently of any
external control. Use the internal control menu (MAN
section) to select the required colour values.
EF d Allows the control of the dual internal chase effects via
external DMX input.
EF M Allows the display of the dual internal chase effects,
independently of any external control. Use the internal
control menu (PROG section) to select the required
chase effects, speeds and cross fades.
4+E Provides control of RGBA mixing and selection of the
dual internal chase effects via DMX input. Requires 11
DMX channels.
16bt Allows RGB(A) control via DMX input, using two 8bit
channels per colour. The RES option determines whether
6 or 8 channels are required. Internal chase effects are
not available within this mode.
PixelArc personalities are available for a variety of controllers.
Please see www.pixelrange.com for details.

Using the menu
• When not in the menu, the four digit display scrolls the
current DMX address and mode. The display’s right hand
decimal point (data dot) is used to indicate status (see below).
• Press to enter the menu. The four digit display will show ADDR.
• Use and to move between menu options (or to change a
value within an option).
• Press to enter an option (or to fix a changed value within an
option and return to the previous option level). Note: If you do
not press to fix a value, operation will revert to the
previously set mode at the next power on.
• Press to exit from a menu option (and eventually
exit the menu completely).
General notes
• Ensure that only one DMX
device in the chain is set
as master (e.g. the lighting
desk). This fixture is usually
set to slave mode.
• This fixture is shipped with
the DMX address set to
001.
• The four digit display can
be set to switch off when
not in use. To restore, press
. To alter this mode use:
PERS >DISP.

To optionally clear all previous settings: Press the
middle two buttons ( and ) while the current
address and mode are being displayed. The four digit
display will show FACT then SET to indicate that the
fixture has been returned to its default condition.
Chase effects
This section describes each of the 31 internal chase effects
that are selectable either via the control menu (prog >
c1/c2 > EFEC) or using DMX values sent from an exter-
nal source. To use the internal effects, set the mode option
either to ef m (to control effects via the menu) or EF d /
4+E (to control effects externally via DMX). See page 4 for
details about controlling effects on other fixtures via DMX
without using a control desk.

Channel layouts within operation modes
The table below shows how colour mixing, chase effects and master intensity
controls are mapped to DMX channels for each mode. The dmx and16bt modes
do not use chase effects. In all modes, the first channel of the fixture occurs at the
DMX address selected using addr and successive channels for the fixture follow
from there.
Note: The PERS >RES option determines the number of channels to use in DMX
and16bt modes (16bt uses twice the number of channels setup within RES).
Channel dmX dmX 16bt) 16bt 4+E
(RES=3CH) (RES=4CH) (RES=3CH) (RES=4CH)
1 Red+Amber Red Red+Amber (course) Red (course) Red
2 Green Green Red+Amber (fine) Red (fine) Green
3 Blue Blue Green (course) Green (course) Blue
4 Master int.* Amber Green (fine) Green (fine) Amber
5 - Master int.* Blue (course) Blue (course) c1 Effect
6 - - Blue (fine) Blue (fine) c1 Speed
7 - - Master int.* Amber (course) c1 Xfade
8 - - - Amber (fine) c2 Effect
9 - - - Master int.* c2 Speed
10 - - - - c2 Xfade
11 - - - - Master int.
*Master intensity for dmx and16bt modes are available only when the
pers > mint option is set to on.
course = High channel for 16-bit, fine = Low channel for 16-bit
Dimming options
(PERS > DIMR)
You have a choice of dimmer
curve control options:
FINE is the standard setting
and is fully compatible with the
dimming curves of previous Pixel
Range fixtures.
TV uses dimming frequencies that
will eradicate any visible flicker
when viewed by video cameras
and broadcast systems.
TUNG Alters the dimming response
to closely emulate the very smooth
action of standard tungsten bulbs.
The TUNG setting can be used with
all operation modes. However,
within the effects modes (EF M,
4+E and EF D), the TUNG setting
will only be effective if the C1/C2
speed option is less than 25 and
the C1/C2 XFADE option is less
than 127.

Master/slave/data indication
The right hand decimal point (data dot) of the display is used
to indicate the master/slave settings and also the presence of
a DMX input signal, as shown below:
Notes:
•Ensure that only one DMX device in the chain is set as
master (e.g. the desk).
•Use PERS > data to change between master & slave modes.
•When set to master mode, the fixture will scroll MASTER in
place of a DMX address (when not within the menu).
•If the display has been set to auto off (disp > aoff), the
data dot will remain active but at a lower brightness.
Data dot ON Master mode
Data dot FLASHING Slave mode (DMX data input present)
Data dot OFF Slave mode (no DMX data present)

Troubleshooting
Fixture remains at blackout when illumination expected
• The display panel (or at least one of its decimal points)
should be lit - if not, check the input power and fuse.
• If live DMX is connected, the right hand decimal point
on the display should flash - if not, check the DMX
cable and the desk output.
• Check that the selected MODE matches the desk per-
sonality being used.
• The master intensity channel for the current mode may
be set at zero. For DMX mode, check the setting of
PERS >MINT.
• Ensure that only one DMX device is set as master.
• Standalone chase effects: Effects programmed using
PROG >C1 and C2 but the fixture is not in MODE >
EF M mode. Check also that MODE > PROG >LEVL
is not set at zero.
• Standalone RGB mixing: Color values set within MAN
section but the fixture is not in MODE >MANU mode.
Fuse access
The main fuse is located within the casing of the fixture.
To remove the fuse
Remove the end panel next to the conduit fittings. Locate
the fuse holder situated between the two connector blocks.
Grip the lever on the left side of the holder and pull it
open to reveal the fuse.

Using master mode to drive other units
This unit can control any number of other Pixel Range
fixtures via DMX links, without the need for a control desk.
1 Set this unit as master (PERS > DATA > MAST) and
ensure all others are set to slave (PERS > DATA >
SLAV). Connect all fixtures via DMX daisy-chain.
2 Set each slave to Mode > DMX. Set the master to either:
• Mode > EF m and use PROG to choose effects, or
• Mode > MANU and use MAN to choose colour mix.
3 Use ADDR > DMX to set slave addresses (the master
unit’s DMX address is ignored):
• Effects: 18 cells are output in groups of 3 DMX channels
to give RGB values per cell (54 channels in total). Set
the address of each slave fixture according to which
of the 18 cells you want them to appear within, or to
begin with (for multi-cell fixtures): (A001 for cell 1,
A004 for cell 2, ... A052 for cell 18).
• Colour mix: Set slaves to any addresses on 3 chan-
nel boundaries, e.g. A001, A004, A007, ... A052.
