James Thomas Pixel Series User manual

General set up
1 Mount the xture in the required position using the supplied yoke
or optional brackets (when multiple xtures are joined).
Important
• When the xture is suspended off ground, always use a safety
wire rated to a minimum of 80kg (176lbs) around the yoke.
• Do not position the xture close to fog machines.
The fog oil mist will be drawn in by the cooling fan and will
short-out important components. The warranty will be void for
all xtures returned in such a condition.
2 Connect the power in and DMX in connectors at the rear of the
xture.
Operation modes
The PixelEight provides a range of operation modes. These are
selected using the MODE section of the control menu:
DMX Allows RGB control of all cells via DMX input. Using the
RES (resolution) option you can determine the number
of DMX channels required, from 24 channels down to
just 3 (the number of cells addressed by each channel
are adjusted accordingly). Internal chase effects are not
available within this mode. An optional master intensity
requires a further DMX channel when enabled.
MANU Provides RGB colour mixing independently of any exter-
nal control. Use the internal control menu (MAN section)
to select the required colour values.
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.
24+E Provides control of RGB mixing of all 8 cells individually
and selection of the dual internal chase effects via DMX
input. Requires 31 DMX channels in total.
3+E Provides control of RGB mixing of all 8 cells collectively
and selection of the dual internal chase effects via DMX
input. Requires 10 DMX channels in total.
PixelEight personalities are available for a variety of controllers.
Please see www.pixelrange.co.uk for details.

3 Where multiple xtures are to be daisy-chained, connect power
out and DMX cables at the rear of the xture.
Important
• When daisy-chaining xtures, do not exceed a total load of
3kW in a single daisy chain (subject to supply and cabling
restrictions). Each PixelEight xture has a maximum power
requirement of 200 watts.
4 When all xtures are connected, apply power.
5 Use the control panel to access the internal menu and choose the
appropriate operation mode and related settings (see over).
• To optionally clear all previous settings: On the control panel,
press the middle two buttons ( and ) while the DMX
address is displayed (e.g. A001, A002, etc). The four digit
display will show FACT then SET to indicate that the xture
has been returned to its default condition.
Joining multiple xtures
Optional brackets are available to allow PixelEight xtures to be
combined in a variety of ways:
Edge brackets
(p/n: SS0545)
Can also be used
to mount xtures
in a horizontal
row.
Back bracket
(p/n: SS0544)
When suspended off
ground, use safety wires
rated to a minimum of
80kg (176lbs) around
the yoke.
The left and right cell mounts can be swivelled
to allow independent focussing of the beams.

Chase effects and master intensity channel layouts
The table below shows how the chase effects and master intensity controls are
mapped to DMX channels for the 24+E and 3+E modes. Mode DMX does not
use chase effects. The rst channel of the xture occurs at the DMX address
selected using ADDR and successive channels for the xture follow from there.
Control 24+E 3+E
C1 Effect Ch25 Ch4
C1 Speed Ch26 Ch5
C1 Xfade Ch27 Ch6
C2 Effect Ch28 Ch7
C2 Speed Ch29 Ch8
C2 Xfade Ch30 Ch9
Master intensity Ch31 Ch10
General notes
• Ensure that only one DMX device in
the chain is set as master (e.g. the
lighting desk). The xture is usually
set to slave mode
• The xture is shipped with the
DMX address set to 001.
• If the xture is used as a master,
DMX transmission will only occur
when the DMX address is displayed
(e.g. A001, A002, etc).
• The four digit display can be set to
fade out after 60 seconds, press
to resume. To alter this mode:
PERS > DISP.
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 external source. To use the internal effects, set
the MODE option either to EF M (to control effects via
the menu) or 3+E or 24+E (to control effects externally
via DMX).

Using the control menu
• When not in the menu, the four digit display shows
the current DMX address e.g. A001
• 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 x a changed value
within an option and return to the previous option level).
Note: If you do not press to x 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).
DMX channel and cell layouts
This section shows the different ways, when
using DMX mode, that the 8 cells can be
mapped to varying numbers of DMX chan-
nels using the PERS > RES option.
The rst channel of the xture occurs at the
DMX address selected using ADDR and
successive channels for the xture follow
from there.
Mode 24+E uses the same RGB mapping
as the 24CH layout and mode 3+E uses
the same RGB mapping as the 3CH layout,
however, the master intensity channels for
these modes are different. The 24+E and
3+E modes also use additional channels
for control of internal chase effects (see the
section below).
(* Mode DMX only, when PERS > MINT is set to ON)

Control menu contents

Options range from 24 through 12, 6 and 3. Cells are grouped together accordingly.
Determines whether this xture will act as a master controlling others.
When controlled via DMX this xture must be set to SLAV.
DMX mode only. When set ON, this enables a master intensity at the channel that im-
mediately follows the number set within the PERS > RES option.
When set ON, this option scrolls through the primary colours at power on
to demonstrate correct operation.
Determines the intensity of the four digit control panel display and blue status
indicators. Values range from 0 (dimmest) to 15 (brightest).
When set to AOFF, the control panel display will blank out 60 seconds
after the menu is exited. The blue status indicators will remain active.
RGB control for cells using variable DMX channels determined by PERS > RES set-
ting. MINT set ON provides master intensity. No chase effects are selectable.
Displays the resulting RGB levels (of all cells combined) that are set via the MAN
section of the internal menu. External DMX control is not possible in this mode.
Displays the chase effect(s) determined within the PROG section. External DMX
control is not possible in this mode.
DMX Ch1 to 24: RGB for indiv. cells, Ch25 to 27: C1 Effect, Speed & Xfade, Ch28
to 30: C2 Effect, Speed & Xfade, Ch31: Master intensity.
DMX Ch1 to 3: RGB for all cells, Ch4 to 6: C1 Effect, Speed & Xfade,
Ch7 to 9: C2 Effect, Speed & Xfade, Ch10: Master intensity.

Troubleshooting
Fixture remains at blackout when illumination expected
• The indicator should be lit - if not, check the
input power and fuse (see below).
• If live DMX is connected, the indicator should
be lit - if not, check the DMX cable and the desk output.
• Check that the selected MODE matches the desk person-
ality 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 in the chain is set as
master (usually the lighting desk).
• Standalone chase effects: Effects programmed using
PROG > C1 and C2 but the xture is not in MODE >
EF M mode. Check also that PROG > LEVL is not
set at zero.
• Standalone RGB mixing: Colour values set within MAN
section but the xture is not in MODE > MANU mode.
Unexpected cell illumination occurring
• When using DMX mode: Check the setting of PERS >
RES. See the section “DMX channel and cell layouts”
on page 2 for an explanation of the various resolution
modes.
Fuse access
The single fuse is located next to the power and DMX con-
nectors. Use a small at blade screw driver to twist the fuse
holder anticlockwise until the carrier can be extracted to
reveal the fuse.
