Picolo Tetra-X Product Description
15
3. Connectors
3.1. “VID
n”
connector
VID1, VID2, VID3 and VID4 are
selectable color or monochrome
composite inputs. They are
terminated with removable 75 ohms
loads.
To modify the 75 ohms termination
setting, see “75 ohms switches”.
3.2. “VEB LINK” connectors
Each 10-pin header connector allows to connect
one Video Expansion Bracket with a Picolo
Tetra-X.
Three VEB LINK connectors are used to add
video inputs to a Picolo Tetra-X. For more
details, see “Video input routing” in part V.
One VEB LINK connector brings back the 4
video signals being digitized. For more details,
see “Video output routing” in part V.
Notes
:
1. Each video differential pair is composed of VIDn and GNDn, both connected to digitizer
n
where
n
= 1, 2, 3 or 4.
2. To inform the system of the Video Expansion Bracket existence, simply short-circuit pin 9
“Presence” with pin 10 “Dig. GND”, digital ground of a Picolo Tetra-X.
3.3. “Digital IO” connector
The “Digital IO” internal connector on the
Picolo Tetra-X has 13 TTL I/O lines that can
be used by the MultiCam software driver as
inputs, outputs or trigger lines.
Other Euresys video capture boards use the
same connector.
3.4. “MIO
LINK”
connector
Using flat cables, this 10-pin header connector allows to interconnect a Picolo Tetra-X to MIO modules.
For more details, see “MIO hardware installation” in part VII.
