Overview
lightJuice CV4 is a dimmer for low-voltage
LED. It provides 4 channels of constant
voltage dimming (i.e. one RGBW circuit) and
is controlled via Art-Net or sACN.
The product supports Power-over-Ethernet,
including the latest standards (PoE++ and
Cisco uPOE). As such, if suitable power
sourcing equipment (PSE) is available, it is
capable of being powered and controlled
solely by the network cable.
Alternatively, an external 24 VDC PSU may
be used to power the product.
lightJuice CV4 is congured via its internal
web browser, or by using the free DMX-
Workshop software application from Artistic
Licence. DHCP is supported for automatic
IP address allocation. The product internally
simulates an RDM device which enables start
address programming.
Summary of Key Features
y4 channels (one RGBW circuit) of LED
dimming
yArt-Net 4 and sACN supported
yPoE++ (IEEE 802.3bt draft) or 24 VDC
yOutput current 3A total (subject to PSE)
y12-bit PWM dimming
ySimulated RDM device
yDHCP supported
Electrical connections
It is recommended that all DC electrical
connections be tted with ferrite cores as
close as possible to the lightJuice CV4.
Ethernet Connection
lightJuice CV4 can be powered from the
network cable. The amount of power delivered
depends on the power sourcing equipment
(PSE). lightJuice CV4 is compatible with all
variants, including the latest PoE++ standard.
The amount of power delivered to the product
is explained in the table below. The PD
(Powered Device) column shows the actual
power that can be used with the maximum
cable length (100m).
lightJuice CV4 features an RJ45 (Ethercon)
connection. This is used for the control data
and, optionally, for power.
Power-over-Ethernet
Modulation
lightJuice CV4 modulates the LED outputs
using 12-bit Pulse Width Modulation. This
technique provides smooth high-frequency
dimming and colour mixing which is
compatible with standard and high-denition
video cameras.
lightJuice CV4 shpould be connected to a
PoE++ enabled port on the network switch or
router, using a straight Cat5e (or above) cable.
lightJuice CV4 is hot-pluggable so the network
interface does not need to be powered o󰀨
before plugging in the device.
Once the PoE++ power sourcing equipment
has detected the device, lightJuice CV4
will power on and the front panel LEDs will
illuminate (see next section, ‘Control data’) .

Control data
The product supports the latest Art-Net
release (Art-Net 4) and sACN (ESTA standard
E1.31). lightJuice CV4 requires Cat 5e cable or
better and supports 10BaseT and 100BaseT.
LED Indication
The front panel LEDs (shown below) have the
following meanings:

Page 6lightJuice CV4 User Guide
Connecting a load
lightJuice CV4 is a constant voltage dimmer,
which means that the output voltage is
dened by the power supply. The LED xtures
connected to the outputs must be designed
for constant voltage operation, which means
they will contain their own current-limiting
mechanism.
lightJuice CV4 is designed to drive 24V rated
RGBW constant voltage LED strip, in common
anode conguration. Normally, Red, Green,
Blue and White will be connected to outputs
1, 2, 3 and 4 respectively (see Connections
diagram).
The common anode can be connected to any
of the outputs marked ‘+’.
The device is rated to provide up to 3A of
current, which equates to a total output power
of 72W.

Internal Web-Browser
To congure lightJuice CV4 via the internal
web-server, either type in the IP address of
the product or, if your web-browser supports
NetBios, enter the name: lightJuiceCV4. To
nd the IP address, use DMX-Workshop or
type “ping 2.255.255.255” in a command
line window (assuming the product is on the
normal Art-Net address range).
Conguration is achived via the internal web
server or via DMX-Workshop (free-of-charge
network management software from Artistic
Licence: Please see:

Virtual RDM Device
lightJuice CV4 is treated as a virtual RDM
device, with 4 sub-devices corresponding
to each output channel of the RGBW circuit.
The start address of the sub-devices can be
chaged in the pull-down menu.
Before running DMX-Workshop, congure the
IPv4 settings of the network card being used
to connect to lightJuice CV4 as shown below.
The IP address can be anything in the 2.*.*.*
range so long as it is di󰀨erent from the IP
address of the lightJuice CV4.
DMX-Workshop™ is a software application
that runs on Windows XP / 7 / 8 / 10. It is a
fully featured network management, analysis,
conguration and diagnostics tool for Art-Net
networks. It is available as a free-of-charge
download from Artistic Licence: http://tinyurl.

DMX workshop screenshot
When lightJuice CV4 is connected to a
computer running DMX-Workshop, it should
be detected and displayed as an Art-Net
node (click the ‘Node List’ tab to verify this).
The node can be expanded to show the
conguration and DMX output information,
as shown in the screen-shot below.
The lightJuice CV4 unit is shown as an Art-
Net node (1) containing a virtual RDM device
(2). The RGBW circuit of lightJuice CV4 is
assigned its own 4 sub-devices (3).
Right-clicking on any entry brings up a menu
that o󰀨ers various functionality:
yThe ‘Congure Node’ option enables
conguration of the Universe, Sub-Net
and Net values. It also allows the user to
give the device a short and long name.
y‘Copy to clipboard’ enables all the node
information to be pasted into a support
request email.
y‘Merge Controls’ (selectable only on
individual DMX outputs) enables the
choice of LTP or HTP merge modes.
y‘Indicators’ enables selection of normal,
identify or mute for the LED indicators.
Normal is the default behaviour, identify
causes the power LED to ash, and
mute turns o󰀨 all the LEDs.
y‘RDM Devices’ o󰀨ers options for device
discovery on RDM networks.
y‘Advanced’ leads to ‘Congure IP
Address’, described in more detail below.

IP Address Conguration
Choosing the ‘Congure IP Address’ in the
‘Advanced’ menu brings up a window that
shows the IP and Subnet Mask.
The IP uniquely identies any nodes or
controllers on a network, while the Subnet
Mask denes which part of the IP represents
the network address and which part represents
the node address. For example, a Subnet
Mask of 255.0.0.0 means that the rst byte
of the IP denes the network address and
the remaining three bytes dene the Node
address.
By default, the product has a static IP address
in the range 2.x.x.x. There are situations in
which the user may wish to change this - for
example, a 192.168.x.x address is generally
used in o󰀩ce environments.
A useful additional feature of lightJuice CV4
is the ability to enable automatic IP address
allocation on networks controlled by a DHCP
server (check the ‘Enable DHCP’ box to
activate this feature). To select static a IP
address, disable DHCP.

Troubleshooting
yAll indicators on the device blink & the device is not on DMX-Workshop
- The device could not be correctly classied by the power sourcing equipment. Try disconnecting
any load from lightJuice CV4 (such as LED strip) while connecting the device, or try using di󰀨erent
power sourcing equipment.
yNone of the indicators illuminate
- There may be a cable fault. Try using a di󰀨erent Ethernet cable, and verify that it is NOT a
crossover cable.
yAll of the indicators are lit, but the device does not show up on DMX-Workshop
- Verify that the device is connected to the network (identied by the LINK and ACT indicators
being lit). If not, try power-cycling the device.
- If you are not already, try running DMX-Workshop as an administrator.
- Check that your rewall settings on both your PC and network switch / router allow tra󰀩c to and
from DMX-Workshop on port 6454 (decimal).
- Check that the network card you have selected in the Network Interface Card (NIC) menu is the
one used to connect to the network switch / router that lightJuice CV4 is connected to.
- Check that the IPv4 settings of said network card follow the correct format (see page 7).
yDevice cuts out when trying to dim LEDs
-Your load may be trying to draw too much current. The device is designed to output a maximum
of 3.0 A at 24.0 V, but if the power sourcing equipment senses an over-current condition it will
terminate the connection to the device. Try using fewer LEDs.
