1.2 Your Safety and Margay’s Safety
The fully assembled display weighs about 68 lbs (30.8
kg). When assembling a wall, you will need two people to handle the Margay.
WARNING
The lamp needs very high voltages to start,
around 15,000 volts.
WARNING
The lamp gets very hot. Allow it to cool before
removing it.
WARNING
The lamp produces lots of light and UV radiation (ultra-violet) as well. UV light can damage
your retinas. After the light leaves the lamp
and passes through the DLP optical engine,
there is no significant UV, although the light
will be very bright.
WARNING
There is no electrical interlock on the screen.
Opening the screen does not turn off the high
voltage to the lamps. s
that is not available, wrap the electronics module
in aluminum foil.
Opening the rear cover does turn off the high voltage
to the lamp. However, the lamp will still be very hot.
. The plug on the power cord serves as the disconnect
for this product. No user serviceable parts inside.
parts replacement is done at the module level by a
qualified service technician.
All
CAUTION
There are no user serviceable parts inside.
Refer all repair and maintenance to a qualified
service technician.
. Static electricity can damage sensitive electronic
components.
• Always use a grounding strap with handling the
electronics module or the optical engine if there
are exposed components.
• When shipping these parts, do not use styrofoam
“peanuts.” These carry static electricity and can
damage the parts. Use an anti-static bag, or, if

2.1 What You Will Do
The series of steps here give only a basic outline of the installation process. See the specific sections for
details (page numbers in parentheses).
Installation
1. Unpack the Margays. Leave the screens in their
containers. You won’t need the screens for a
while.
2. If it was purchased, install the VIM (Video Input
Module) in each Margay. (10)
3. If it was purchased, install the Big Picture key in
each Margay. (12)
4. Build the wall of Margays, leaving the screens off.
(14)
5. Connect the Margays to power (26), picture
source (22 & 24) and communication. (28)
6. Install the screens, starting with the bottom row.
(32)
Configuration
1. Align each optical engine to the screen. (38)
2. Adjust Margay to each of the inputs you will use:
analog computer (44), digital (48), video (50).
3. Color balance the wall. (52)
4. Set up Big Picture, if you are using it. (54)
5. Save your work. (62)

2.2 Installing the VIM (Video Input Module)
It is easier to install the VIM board in Margays before they get stacked in a wall.
The Video Input Module option is installed in the
field.
You will install the VIM (Video Input Module) in the
Margay’s electronics module. (The electronics module is the part the receives all the input and output
cables.)
If the electronics module is installed in the Mar-
gay, you will remove it partially.
1. Turn off the AC power to the Margay and remove
the power cord.
2. Open the door on the right side of Margay (as
viewed from the front) exposing the electronics
module.
4. Pull the module up and partly out.
a. It may take a bit of maneuvering to get the con-
nectors at the bottom to come up with the
module.
b. Do this carefully so you do not damage the con-
nectors. All connectors are latched in place.
They aren’t particularly delicate, but they won’t
stand very rough treatment.
5. Install the VIM in the electronics module.
3. Loosen the two screws at the top of the electronics
module.
10
6. Put in the four screws. Be sure the VIM is pressed
well into the socket.
One of 4 screws.
7. Put the electronics module back in place and
secure it with the two screws.
8. Reconnect power, if you removed it earlier.
11
2.3 Installing the Big Picture Key
Clarity’s Big Picture™ key allows a wall of Margays to spread one picture over the entire wall.
The Big Picture key is installed in the field. You can
install the Big Picture key without removing the electronics module.
1. Open the door to the electronics module.
3. Plug the BP key into its socket.
CAUTION
Be sure all six pins go in the socket holes. If
the key is installed incorrectly, the entire electronics module may not function at all.
2. Remove the cover of the Big Picture key socket.
12
4. Replace the BP key cover.
The Big Picture key can be installed while the Margay
has power. However, the key will not take effect (Big
Picture will not work) until power is cycled on again.
13
2.4 Building the Wall, First Row
It is most important to make the first row straight. Do not put the screens on yet.
Laying the first row
1. Set the first row of Margays side by side without
the screens. Bolt them loosely together near the
bottom with the long side-to-side bolts, washers
and wingnuts.
2. Attach the screen supports to the front edge of the
first row. The screen support only mounts one
way and is used on the bottom row only. It provides a stop or rest for the bottom screens.
3. Check the straightness of this row. This first row
must be absolutely straight.
Do not use your eye alone to judge straightness. Use a
tightly stretched string or a very long level. It is ok if the
row is not level, as would be the case in a tilted wall, but
it must be straight.
4. Use shims under the Margays to make the row
straight vertically.
5. When the row is straight, tighten the bolts holding them together. Then check straightness one
more time.
6. Go to next section (page 16).
Why is straight so important?
All Clarity display that stack must have a straight
first row. If the first row is not straight, the arrangement gets worse as the wall goes up, and the screens
won’t align properly.
Margay is a little more critical of straightness,
because its screens have almost no mullions.
The mullion is the outside border of the screen. In
most Clarity products this is a narrow edge of metal
that holds the screen in place. In Margay the mullion
is a thin piece of tape.
The advantage of this “mullion-less” screen is that
the finished wall will have almost no black lines
between images on the screens.

2.4 Building the Wall, First Row
2.4.1 Building the Wall, Second Row and Up
If the first row is straight and solid, the rest of the rows will be easier.
Continuing to build the wall
1. Stack another row of Margays on the first row. As
you stack, be careful with the pins that align the
rows.
3. Then bolt the Margays top-to-bottom through the
top-to-bottom hole using the Vertical bolts,
¼"-20.
2. As each Margay is placed in the second row,
secure it to the lower unit with two Front screws.
4. Bolt this row side-to-side as you did the first row.
This time the bolts will go through four Margays,
two in the first row, two in the second rows. The
16
end of the row has shorter side-to-side bolts to
secure just two Margays together.
5. Check straightness of this second row.
CAUTION
For high walls, over 2 units high, and for all
tilted walls, see the safety instruction below.
Safety with high or tilted walls
Because the Margay is so narrow front to back,
there is a danger of tipping with high walls. Margay
has tie-back points on the rear to prevent this.
Use these tie-backs to secure the Margay wall to a
structural part of the building. Don’t wait until the
wall is finished. Do this as you build the wall up.
If the wall is tilted forward, tie the Margay all the
way up.
6. Continue in this way with the rest of the rows,
checking straightness as you go.
Make sure the fronts of the
units are flush with each
other. This will make screen
alignment easier.
The tie-back points are ¼”x20 threaded holes.
17
2.4 Building the Wall, First Row
2.4.2 Building a Banner, Upside Down
It is possible to hang a single row of Margays upside down to make a banner. Be sure the ceiling can
hold them.
Clarity does not provide any special brackets to hang
a Margay upside down. There are too many variables
to consider, so the method to use is best determined
on site.
Whatever you use to attach Margays overhead, it
must be capable of sustaining five (5) times the
weight of a Margay, which is 68 lbs or 30.8 kg. The
mounting system must therefore hold 340 lbs or 154
kg for each Margay.
You may use the screen supports to cover part of
the Margay, but they are not necessary in the upside
down configuration.
Inverting the picture and menus
In the Miscellaneous menu (under Advanced
Options) check Inverted Installation. This one check
mark inverts the picture and the menus. It also
reverses the left-right of the optical engine alignment
motors so left and right will be correct for you.
M
ENU > ADVANCED OPTIONS > MISCELLANEOUS
Screens when inverted
The screen supports, which normally hold screens
up, will now be above the row of screens. You may
wish to devise some way to push the screens up from
the bottom to press them against this support to prevent a gap.
It is not necessary, of course, to use the screen support parts in an inverted installation.

2.5 Connections
Margay has four groups of connectors. All inputs are paired with loop-thru outputs (except RS232 In).
The inputs are toward the rear of the Margay.
Analog and digital connectors
Two analog connectors and one digital (DVI) connector have their separate loop-thru outputs. The
Analog outputs (buffered) always carry the corresponding analog input picture.
The digital output is different. The digital output
carries a digitized version of the selected input. If you
change the active input in the Picture menu, the digital output changes.
• See 2.5.1 “Connections, Analog & Digital
Sources” on page 22.
Video connectors
Video connections are optional. The Video Input
Module (VIM) is not installed at the factory; it is
installed in the field by the installer. When installed,
the VIM accepts composite, S-video and component
video (YPbPr). Each input connector is paired with its
separate loop-thru output.
• See 2.5.2 “Connections, Video Sources” on
page 24.
Control connectors
You can control the Margay with a remote control
or with serial commands from a computer or other
device. Send commands in either the RS232 or
RS485 standard.
Normally, you send RS232 commands to one Margay’s RS232 In and loop out the RS485 Out to the
next cube’s RS485 In.
RS485 has better long-distance communication.
• See 2.5.4 “Connections, Control: RS232 &
RS485” on page 28.
• 8 cubes when using 230V.
No more than 4

115 VAC
• See 2.5.3 “Connections, Power” on page 26.
Power
AC power (115V or 230V) can be looped thru to
neighboring cubes. The limit on loop-thru is
• 4 Margays when using 115V;
• 8 Margays when using 230V.
The power supply is auto-ranging.
