Configurations
The two-wire data bus is used to connect all control units in
the Series 9000 control system. The data cable loops-through
from one unit to the other. The order of connection is not
important, however, the total length of the cables must not
exceed 310 meters (1,118 ft).
Each unit connected directly to the data bus, either Base
station, camera head or OCP, is identified by a number. In
order to ensure, for example, that OCP 1 controls the camera
connected to Base station 1, the same unique number must
be assigned to both OCP 1 and Base station 1. The assignment
number is set internally on the units during installation.
The assignment number of a camera head connected to a
Base station is automatically set to the number of the Base
station to which it is connected. The number on the Base
station, which is connected to the data bus, must be set to the
number of the assigned control panel.
It is important to set a unique number for each Base station/
OCP group as unpredictable control situations could arise
otherwise.
The MCP is also connected to the data bus, however, it is not
necessary to set an internal assignment number. The camera
or cameras to be controlled are selected on the MCP front
panel itself when operating the unit.
Private Data
A private data channel is also available between the camera
and the Base station. This is a two-way serial channel
operating at 2400 B/s with TTL level. This channel can be
used for digital data links. For detailed information refer to the
Base station's User's Guide.
Analogue Ch0-Ch1
Two analogue control channels are available from the Base
station to the camera. These provide a control voltage from
0V to +5V that can be used for pan control for example. For
more information on these channels refer to the Base station's
User's Guide.
Note: If the analogue Ch1 is used to externally switch the
Aspect Ratio, Ch 1 is not available for analoque
signals from the Base station to the camera.
Note
A maximum of 15 looped-through standard camera
systems in one chain can be handeld, however, in
a multiple system the load of a LDK 23 HS (mkII)
is twice the load of a standard camera.
