Two-wire Data Control Bus

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 350 metres.

Each unit connected directly to the data bus, either CPU, camera head or OCP, is identified by a number. In order to ensure, for example, that OCP 1 controls the camera connected to CPU 1, the same unique number must be assigned to both OCP 1 and CPU 1. The assignment number is set internally on the units during installation.

The assignment number of a camera head connected to a CPU is automatically set to the number of the CPU to which it is connected. The number on the CPU, which is connected to the data bus, must be set to the number of the control panel that is to control it.

A camera connected directly to the data bus must have its assignment number set to the number set on the OCP that is to control it. It is important to set a unique number for each CPU/OCP or camera/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.

Note

A maximum of 15 looped-trough 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 so with level 1 communication software the system can handle a maximum of 8 LDK23 HS (mkII) camera's.

Other Control Features

Private Data

A private data channel is also available between the camera and the CPU. This is a two-way serial channel operating at 2400 B/s with TTL level. This channel can be used for digital data links (Refer to the Installation Manual for more detail).

Analogue Ch0-Ch1

Two analogue control channels are available from the CPU 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 Installation Manual.

Note

If the analogue Ch1 is used to switch externally the Aspect Ratio, Ch 1 is not available for analoque signals from the CPU to the camera.
