6 VC-Grid Safety and Installation Guide
- If you supply a chain of VC-Grid modules with DC power from a generic 48 VDC external PSU (power
supply unit), do not connect more than one linked chain of VC-Grids to one DC power output at the
PSU, and do not exceed the maximum permitted number of modules that you can connect in one chain
as given in Table 3 below. At the same time, do not create a chain that will exceed the maximum power
rating of the PSU output used to supply that chain with power (to find the power consumption of the
chain, multiply the number of modules in the chain with the wattage of each module as given in Table 3).
Each time you reach (a) the maximum permitted number of modules in one chain, or (b) the PSU
output’s maximum power rating – whichever you reach first – you must create a new chain of modules
that is connected to a new 48 VDC power output.
• If you supply a chain of VC-Grids with DC power from a generic 48 VDC external PSU and the DC
output used does not have constant overcurrent protection that limits current to 8 A, install an inline
fuseholder with a 7.5 A or 8 A fuse on the circuit that you connect to that DC output.
• Provide a means of locking out AC mains power that allows power to the installation to be shut down and
made impossible to reapply, even accidentally, during work on the installation.
• Shut down power to the installation during service and when it is not in use.
• Before applying power to the installation, check that all power distribution equipment and cables are in
perfect condition and rated for the current requirements of all connected devices.
• Isolate the installation from power immediately if any product, power cable or power plug is in any way
damaged, defective or wet, or if it shows signs of overheating.
• Do not expose the VC-Grid to rain or moisture.
PROTECTION FROM BURNS AND FIRE
• The VC-Grid is cooled by convection. Provide free airflow and a minimum clearance of 10 mm (0.4 in.)
around modules. Monitor the VC-Grid’s temperature by calling up temperature readouts on the P3
System Controller. If any of the product temperature readouts exceed the levels given in Table 4 on page
8, provide fan assistance to give active cooling to the installation.
• Do not operate the VC-Grid if the ambient temperature (Ta) exceeds 45° C (113° F).
• Do not modify the VC-Grid in any way not described in this manual or install other than genuine Martin
parts. Use only accessories approved by Martin.
PROTECTION FROM INJURY
• When installing the VC-Grid above ground level, ensure that the installation hardware and supporting
structure can hold at least 10 times the weight of all the devices they support.
• In an overhead installation or where the VC-Grid may cause injury if it falls:
- block access below the work area and work from a stable platform whenever installing, servicing or
moving the VC-Grid, and
- as soon as work is completed, check that all hardware and components are securely in place and
fastened to supporting structures.

Introduction 7
Introduction
Thank you for selecting a product from the Martin VC-Grid™ family. These compact LED-based display
modules are designed to integrate into a Martin P3™ video system to display video from a variety of
sources, and they can also be controlled using DMX. Use of an RDM-compliant DMX controller allows
two-way communication and remote management of VC-Grid modules from the controller.
The VC-Grid combines flexibility and simplicity with high-quality video display capabilities. Used with or
without a front diffuser, multiple VC-Grids can be combined in ways that give exceptional creative flexibility.
A hybrid power and data cabling system allows VC-Grids to be daisy-chained for easy setup and minimal
cabling.
The VC-Grid is a square array of LEDs arranged on a rigid module. It offers the following features:
• RGB color
• Various pixel pitch (center-to-center LED distance) options: 15, 25, 30 or 60 mm
• Three pixel layout options: 4x4, 8x8 or 16x16 LEDs per module
• Individually controllable pixels
• High-quality 16-bit per color image processing technology
• Pixel-level brightness and color calibration for optimal image quality
• P3 and DMX control with automatic protocol detection
• Intuitive pixel mapping and addressing using a Martin P3 system controller
• Single hybrid cable for power and data input and throughput
• External power and data processor (Martin P3 PowerPort™) and simple cabling system.

Precautions to avoid damage
Important! To get the best out of the VC-Grid and avoid causing damage that is not covered by the
product warranty, read the following information carefully. Make sure that everyone who is involved
in working on or using the VC-Grid has read and understood this information.
• The VC-Grid is not designed to allow hot-plugging. Shut down power and data before connecting or
disconnecting modules, or you are very likely to cause damage that is not covered by the product
warranty.
• PCB tracks can be damaged if metal screws are tightened directly onto VC-Grid modules. Protect PCBs
from damage by adding non-conductive protective material such as plastic PCB washers or spacers
under screw heads to prevent any abrasion of PCBs. Mechanical damage to PCB tracks caused by
fastening hardware is not covered by the product warranty.

8 VC-Grid Safety and Installation Guide
• Excessive dirt buildup causes overheating and a risk of short-circuits and may damage the product.
Damage caused by inadequate cleaning is not covered by the product warranty.
Operating temperature precautions
• Exposing the VC-Grid to direct sunlight or operating it in an ambient temperature that exceeds the
specified maximum may reduce the lifetime of the product. Monitor the VC-Grid’s temperature by calling
up temperature readouts on the P3 System Controller. If any of the product temperature readouts exceed
the temperatures given in Table 4, provide fan assistance to give active cooling to the installation.
• Note that, if the temperature of a VC-Grid module rises to 10° C above the level given in Table 4, a
thermal safety cutout shuts down the module. The module will not function normally again until the
temperature has fallen to a safe level.
Electrostatic discharge precautions
VC-Grid components are sensitive to ESD (electrostatic discharge) and can be damaged if you do not take
the following precautions:
• Attach an ESD wrist strap to your wrist and connect its ground (earth) lead to a known ground (earth)
before handling the VC-Grid.
• Hold the VC-Grid by its edges only. Do not touch any part of a VC-Grid module apart from the connectors
and the control button. Do not touch connector pins.
• Place the VC-Grid on grounded (earthed) surfaces only.
• Store the VC-Grid only in its ESD shielding bag and do not remove it until you are ready to install it. Place
it in an ESD shielding bag immediately if you remove it from an installation.
• Protect the VC-Grid from ESD in the installation location. Differences in electrical potential between the
VC-Grid and any object it comes into contact with may cause damage that is not covered by the product
warranty.

10 VC-Grid Safety and Installation Guide
Physical installation
Warning! Read “Safety Information” on page 4 and “Precautions to avoid damage” on page 7 before
installing the VC-Grid.
The VC-Grid can be installed in any orientation.
The backs of modules are marked with arrows and the word TOP. To ensure the most evenly matched
optical characteristics when viewing VC-Grids at an angle, install all modules with the arrows facing the
same way. In vertical arrays, install all modules with the arrows pointing upwards and the TOP marking at
the upper edge of the modules.
Allow free airflow around the product and at least 10 mm (0.4 in.) of clearance around the LEDs on the front
surface.
To maintain even pixel spacing across multiple VC-Grids so that they form a seamless display surface,
install them with the following gaps between the edges of modules, both horizontally and vertically:
See Figure 2. The VC-Grid can be fastened to a surface or structure using pillar bolts through any four of the
mounting holes (arrowed). Arrange pillar bolts so that they are evenly spaced around the product. Add
non-conductive washers on both sides of the VC-Grid.

12 VC-Grid Safety and Installation Guide
System installation
Warning! Read “Safety Information” on page 4 and “Precautions to avoid damage” on page 7 before
installing a VC-Grid system. Pay particular attention to the limits given in ”Protection from electric
shock” on page 4.
Warning! Connect the VC-Grid to only the devices specified in this manual and using only the Martin
cables specified in this manual.
Warning! Do not exceed the maximum numbers of devices that can be connected in chains and
maximum cable lengths specified in ”Protection from electric shock” starting on page 4 and in the
manuals of the other devices in the system.
Important! The VC-Grid is not designed to allow hot-plugging. Shut down power and data before
connecting or disconnecting modules, or you will probably cause damage that is not covered by the
product warranty.
The VC-Grid is designed to display either Martin P3 video or DMX-controlled lighting effects. It automatically
recognizes and responds to either a P3 or a DMX data signal. The next sections explain how to create a
VC-Grid installation to display P3 video data or DMX-controlled lighting effects.
Installing a P3 system
See Figure 5 on page 14 for an overview of a Martin P3 video display system.
The P3 link requires Ethernet Cat 5e or better network cable. The cable run between any two devices on the
link can be up to 100 m (328 ft.) in length. If necessary, a cable run can be extended beyond 100 m by
inserting an unmanaged Ethernet switch or using a fiber-optic system (see the P3 system controller user
manual for details).
To install a system that displays Martin P3 video on VC-Grids, see the P3 system overview in Figure 5 and
follow these directions:
1. Make sure that no devices in the installation can be connected to AC mains power until all installation
work is complete.
2. Read “Safety Information” on page 4 and “Precautions to avoid damage” on page 7.
3. Connect VC-Grid modules together in chains using Martin hybrid PCB-to-PCB cables (see ”VC-Grid to
VC-Grid link cables” on page 30). Connect each cable from the THRU connector of one VC-Grid to the
IN connector on the next VC-Grid to create the chain.
Warning! Do not exceed the maximum lengths for chains given in ”Protection from electric shock” on
page 4.
4. Connect each chain of VC-Grids to one of the four 4-pin female XLR hybrid (48 VDC power + P3 data)
outputs on the P3 PowerPort 1500 using a Martin hybrid 4-pin male XLR-to-PCB adapter cable,
P/N 91616035 (see Figure 4).

If necessary, extend the cable by connecting a Martin 4-pin XLR hybrid extension cable to the
Hybrid-to-PCB adapter cable so that you can run the hybrid link to the P3 PowerPort 1500. Suitable
extension cables are available from Martin in various lengths. See ”Extension cables” on page 30.
5. Create a P3 video data link from a Martin P3 system controller such as the P3-050™, P3-150™ or P3
PC™ to the P3 PowerPort (see the products’ user manuals for details).
6. If required, continue the P3 video data link in a daisy-chain by connecting the P3 data throughput of one
P3 PowerPort 1500 to the P3 data input of the next, as described in the P3 PowerPort 1500’s user
manual. You can connect up to fifty P3 PowerPort 1500s in a P3 data daisy-chain like this. If you need to
connect more than fifty, use an unmanaged Ethernet switch to split the P3 data link into branches, each
containing less than fifty P3 PowerPort 1500s.
7. Connect the P3 PowerPort 1500 to AC mains power at 100 - 240 V, 50/60 Hz as described in its user
manual.
8. Connect the P3 system controller to AC mains power and power the controller on.
You can now configure the system at the P3 controller. See”System setup” on page 21.
Note: Use of the Martin P3 PowerPort 1500 to send DC power and video data to VC-Grids via Martin hybrid
cable is the easiest and most economical solution when preparing a VC-Grid installation for P3 video
display. It is possible to use an IP65- or IP66-rated Martin P3 PowerPort 1000 IP device instead of the P3
PowerPort 1500, but this option will require custom-made hybrid cable and will probably be less economical.
If you wish to use a P3 PowerPort 1000 IP in a VC-Grid installation, please contact your Martin supplier for
advice.

Installing a DMX-controlled system
In a DMX-controlled system, an RDM-compliant DMX lighting controller sends a DMX control data signal
over a DMX link to the installation, and then over the hybrid link to the VC-Grids.
The DMX link requires DMX cable. It can be maximum 300 m (1000 ft.) in length and must run in one single
daisy-chain, but it can be extended or split into branches using an RDM-compliant amplifier/splitter such as
the Martin RDM 5.5 Splitter™ (P/N 90758150). Alternatively, you can run the DMX signal from the controller
over Ethernet cable using Art-Net protocol and convert it to a DMX-compliant signal with a standard Art-Net
to DMX node.
If you would like assistance with creating a DMX link, your Martin supplier will be glad to advise.
The number of VC-Grids that you can control on one DMX link is limited by the number of DMX channels the
VC-Grids will use and the 512 DMX channels available in one DMX universe at the DMX controller. Each
time you have used 512 channels, you must create a new DMX link that is connected to a new DMX
universe on the controller. Note that this limit applies to the DMX link. The maximum safety limits that apply
to the hybrid link (see “Safety Information” on page 4) take priority and must be respected in all cases.
DC Power options in DMX installations
A DMX-controlled VC-Grid installation can be supplied with DC power from the Martin IP66 PSU 240W
external PSU or from a generic external PSU that can supply DC power at 48 V (the Mean Well SP-480 48,
for example).
The hardware and cables required are slightly different depending on which type of PSU you use to supply
the installation with DC power. The two different types of installation are covered in the next two sections:
• If you are using a Martin IP66 PSU 240W, see ”Installing a DMX system using the Martin IP66 PSU
240W” on page 16.
• If you are using a generic 48 VDC PSU, see ”Installing a DMX system using a generic 48 VDC
external PSU” on page 18.

Connecting additional devices to a VC-Grid chain
Drawing off combined data and DC power from the end of a chain
If you want to continue the hybrid link to carry 48 VDC power and a P3 video or DMX signal from the end of
a VC-Grid chain to other devices, connect a Martin Hybrid Adapter Cable, PCB to 4-pin female XLR, P/N
91616036, to the OUT connector of the last module in the chain.
Warning! If you draw off DC power from the end of a VC-Grid chain and connect additional devices,
respect the maximum safe power rating of the power source that you use to supply all the devices
with DC power. Calculate the power consumption of the VC-Grid chain using the figures in Table 3
on page 6, then add the power consumption of each device that you add to the end of the chain. As
soon as you reach 360 W – or the maximum power rating of the device that you use to supply the
chain with DC power if this rating is lower than 360 W – you must stop adding devices and create a
new chain that draws DC power from a new source.
Drawing off a DMX signal from the end of a chain
If you want to continue the DMX link to carry a DMX signal from the end of a VC-Grid chain to other devices,
connect a Martin Hybrid Adapter Cable, PCB to 4-pin female XLR, P/N 91616036, to the OUT connector of
the last module in the chain.
Then, to connect to a standard DMX link that uses 5-pin XLR connectors, add a Martin Data Out/Thru
Adapter Cable, 4-pin male XLR to 5-pin female XLR, P/N 91616040. This adapter cable relays the DMX
data signal only, it does not collect DC power at its 4-pin male XLR connector.
System setup 21
System setup
Warning! Read “Safety Information” on page 4 and “Precautions to avoid damage” on page 7 before
applying power to the VC-Grid.
Setting up for P3 display
A Martin P3™ system allows video to be displayed on an installation that consists of or includes VC-Grid
modules. When a P3 controller is connected to the P3 data link and the installation is powered on, you can
set up all the devices on the link from the P3 controller. See the P3 controller user manual for details.
Setting up for DMX control
A DMX system gives 0 - 100% variable intensity control. Varying the intensity of red, blue and green LEDs in
RGB products provides RGB color mixing. Setting red, blue and green to 100% intensity gives white, with
the option of adjusting color temperature using the red and blue LEDs.
You can set up and control a VC-Grid installation over the data link using an RDM-compatible DMX
controller.
DMX control channels
DMX controllers send control data to devices over DMX control channels in DMX universes. One DMX
universe has 512 channels available.
One DMX channel is required for each control parameter of each element in the installation. An element can
consist of an individual pixel, a VC-Grid module, or a group of modules, depending on how you set up the
VC-Grids. A control parameter can consist of red intensity, for example. So, red intensity control of one
element in an installation uses one channel. RGB control of a VC-Grid installation requires three channels
per element.
• If you set a VC-Grid to individual pixel control, you can control each LED on that VC-Grid as an individual
pixel using its own DMX channels – three channels per pixel.
• If you set a VC-Grid to module control, you can control all the LEDs on that VC-Grid as a group using the
same three DMX channels. Individual control of the pixels on that VC-Grid module is impossible.
• If you set multiple VC-Grids to module control and also set up those VC-Grids to use the same DMX
channels, you can control all the VC-Grids as a group using the same three DMX channels. Individual
control of the pixels or modules in the group is impossible.

Table 5: Number of DMX channels required per VC-Grid module
22 VC-Grid Safety and Installation Guide
Calculating the number of DMX channels required
A VC-Grid installation uses the three DMX channels required by each element (individual pixel, module or
group of modules) multiplied by the total number of elements in the installation. For example, an installation
containing fifty VC-Grid 8x8 RGB modules will require:
• 3 DMX channels if the entire installation is controlled as one group,
• 3 channels x 10 groups = 30 DMX channels if the installation is divided into ten groups that are controlled
individually,
• 3 channels x 50 modules = 150 DMX channels if each of the fifty modules is controlled as an individual
group, and
• 3 channels x 50 modules x 64 pixels = 9600 DMX channels if each of the 3200 pixels is controlled
individually (in this example, 19 DMX universes will be required because one DMX universe has 512
channels).
Pixel and module modes
If you set a VC-Grid to pixel mode, each pixel on the module is controlled individually (apart from the
VC-Grid 16x16, where pixels are controlled in groups of four).
If you set a VC-Grid to module mode, all the pixels on the module are controlled together as one group.
The interfaces of RDM-compliant controllers vary depending on the producer, but you should be able to find
the pixel and module mode options in the Settings or Options area of your controller.
Individual and grouped control can be mixed freely in an installation. For example, some VC-Grid modules
can be set up for individual pixel control, other modules can be set up for individual module control, and
other modules can be put into groups for grouped control of multiple modules.
DMX addresses
To prepare an installation for DMX control, you need to set it up using an RDM-compliant DMX controller so
that each individually controlled element (pixel, module or group of modules) will receive instructions from
the controller on its own DMX channels. The DMX address (also known as the control address or start
channel) is the first of these channels. If an element requires more than one DMX channel, it uses the DMX
address channel and the channels immediately above it. For example, if you set a VC-Grid RGB module to
module mode so that you control all its pixels as one group, and if you set it to DMX address 1, it will use
DMX channels 1 - 3. Channel 4 will be available for use as a DMX address for the next device.
If you set a VC-Grid to pixel mode so that you can control individual pixels, its LEDs use DMX addresses
according to a ‘left-to-right, then down’ numbering system (like the reading order of the words on this page).
For example, if one VC-Grid 8x8 RGB module is set to pixel control and set to DMX address 1, each of the
module’s 64 LEDs will use 3 channels, and the module will use DMX channels 1 - 192 (Channel 1 -3 for the
top-left pixel, channels 4 - 6 for the next pixel on the right etc. until it reaches channels 190 - 192 for the last
pixel at the bottom on the right. Channel 193 will be available for use as a DMX address for the next device.
If you set a VC-Grid to module mode so that you control it as one module, it will use three DMX channels as
described above. If you want to create a group of modules that you always control together, give all those
modules the same DMX address. All modules that have the same DMX address will receive the same
instructions and behave identically.
Setting up via RDM
Using an RDM-compliant DMX controller, you can communicate with the VC-Grid modules on the DMX data
link via RDM. You can:
• Retrieve data
• Set the DMX addresses of the groups or pixels on the link
• Set modules to grouped or pixel control modes (see above)
• Apply various setup options.
See the controller’s user manual for details of how to retrieve information from and send commands to the
VC-Grid.

Cleaning
Cleaning schedules vary greatly depending on the operating environment. It is therefore impossible to
specify precise cleaning intervals for the VC-Grid. In extreme cases, the product may require cleaning after
surprisingly few hours of operation. Environmental factors that may result in a need for frequent cleaning
include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment in outdoor
locations, for example).
If one or more of these factors is present, inspect products soon after installing them to see whether
cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess cleaning
requirements in your particular situation. If in doubt, consult your Martin dealer about a suitable
maintenance schedule.
Important! Electrostatic discharges may cause damage. Do not touch the VC-Grid with fingers or a compressed
air nozzle.
To clean the product, use low-pressure compressed air to gently remove dust and loose particles from the
front and back of the product. Avoid touching the product’s conductive surfaces and electronic components.
Installing new software
It may be necessary to upload new software (i.e. device firmware) to the VC-Grid if it appears to have a
software-related fault or if you want to update to a newer software version.
Software for Martin products is available from the Martin website. The VC-Grid software can be installed
from the P3 System Controller over the P3 data link. See the P3 System Controller user manual for software
installation instructions.
