The
Mosaic is a PCI plug-in card which has been designed to operate
in conjunction with the Datapath iH4-DIG graphics card. The
Mosaic, when combined with the iH4-DIG, provides up to 9 separate
video overlay windows. For systems that require more than 9
overlay windows, up to 4 Mosaic cards can be installed giving
a total of 36 video windows.

Multiple
Mosaic Cards
For
systems that require more than 9 overlays, multiple Mosaic cards
can be installed. There are many possible configurations with
two methods of connecting Mosaic's to Horizon cards.
Method 1:
Each Mosaic (maximum of 4), is connected to all iH4-DIG,
(maximum of 8), in the system. This allows any Mosaic window
to be displayed anywhere on the desktop. Maximum screens = 32
and 36 video windows.
When
the MBM-H2 or MBM-H4
is used in the system this allows up to 8 iH4-Dig cards to be
used in the system. Maximum screens = 32 and 36 video windows.
Method
2:
If more than 36 video windows or more than 32 screens are required,
the wall can be arranged so that the windows are displayed over
part of the wall. Each iH4-DIG card is configured to control
a particular group of 4 screens using Wall Control software..
You can decide how many video windows are required for each
group of 4 screens that will be controlled by the iH4-DIG. For
each iH4-DIG, connect up to 4 Mosaic Cards, this allows you
up to 36 video windows for each set of 4 screens. If some video
windows are required to be displayed over more than 4 screens
or need to be moved over more than 4 screens, then the Mosaic
cards can be connected to each iH4-DIG card that you want the
video overlays to operate over.
Rules
for Connecting Mosaics:
-
Each Mosaic can be connected to a maximum of 8 iH4-DIG when
using the MBM.
-
Each
iH4-DIG can be connected to a maximum of 4 Mosaic Cards.
-
Video
overlays from a particular Mosaic card can only appear on
the screens driven by the iH4-DIG card it is attached to.
Restrictions:
-
The maximum number of video windows on a single screen is 9.
- Video
windows from separate Mosaic cards cannot be displayed on the
same screen.
Maximum
Configuration:
- 8
iH4-DIG cards = 32 screens (using the MBM-H4)
- 16
Mosaic cards = 144 video overlay windows.
Cables/Accessories
As
standard the Mosiac cards are shipped with the M2H4 cable set
and 2 x 16 way BNC Splitter Cables.
Due
to the many configurations possible with the Mosaic card, various
cable sets are available to order:
Cable
Sets
M2H1-cable
- Connects 1 or 2 Mosaic cards to 1 iH4-DIG.
M4H1-cable - Connects 4 Mosaic cards to 1 iH4-DIG.
M2H4-cable - Connects 1 or 2 Mosaic cards to 1, 2, 3 or
4 iH4-DIG.
M4H4-cable - Connects 4 Mosaic cards to 1, 2, 3 or 4 iH4-DIG.

Mosaic
Buffer Modules
If
you require more than 4 iH4-DIG cards to be connected to your
Mosaic cards then by adding the Mosaic Buffer Module (MBM) to
the M2H4 or M4H4 cable sets, you can increase the number of iH4-DIG
cards to 6 or 8 respectively.
The
MBM-H2 and MBM-H4 have a small PCB that is attached to the J3,
J7 and J8 headers on the iH4-DIG enabling 6 or 8 cards to be conected
to your Mosaic cards.
MBM-H2
The
diagram below illustrates how the MBM-H2 is used with 4 x Mosaic
and 6 x iH4-DIG
MBM-H4
The
diagram below illustrates how the MBM-H4 is used with 2 x Mosaic
and 8 x iH4-DIG.
