2.5.1 Connections, Analog & Digital Sources
The Digital Out connector carries the selected input.
All of the source inputs, the picture inputs, have
loop-thru output connectors. These loop-thrus are
buffered.
•
Analog 1
and
Analog 2
are 15-pin VGA-type con-
nectors. Margay will accept a wide range of com-
puter resolutions up to 1600 × 1200 and
1920 × 1080. Each of these connectors has a ded-
icated loop-thru output. These connectors are
also used for RGB video with separate H&V sync,
composite sync, or sync on green; also for YPbPr
video at 480p, 720p, or 1080i.
When an Analog input has a source with sync on green
or composite sync, the DVI Out may not show the
picture properly. If the source is present at power up, it
usually works well, but if you disconnect and reconnect
the source, the DVI loop-thru stops working for these
two types of sync.

Digital
In
is a standard DVI cable. It has a loop-
thru, but this Digital Out connector is
not
dedi-
cated to the Digital In connector. Instead, the
Digital Out connector carries the picture of the
currently selected input. For instance, if the
Analog 1 connector is selected, the picture on the
Digital Out connector is a DVI version of that
Analog 1 picture.
The DVI does
not
carry the picture from the composite,
the S-Video, or the component YPbPr inputs.
Limits of loop-thru
No signal can loop-thru forever. There is always
some degradation of the signal along the way.
If you want to loop a single source to a number of
Margays, try one of the methods shown here. In dia-
gram A the signal loops thru six times at most. In
diagram B the signal loops thru four times at most. In
each diagram the cubes marked
X
is the farthest from
the source.
