Direct Camera Control
6.2 Direct Camera Control
With Direct Camera Control (DCC) it is possible to connect one AutoDome camera directly to a
CCU. In combination with the relevant software DCC can direct the AutoDome camera towards
speaking conference participants. The DCC can only be used in combination with:
• A BOSCH AutoDome camera
• A CCU with TCB 4 or higher
• DCN software 9.30 or higher
6.2.1 Virtual Keyboard
A virtual keyboard is used to set the pre-positions of the AutoDome camera. The virtual keyboard
software LTC 5138/00 must be installed on your temporary PC or DCN control PC.
6.2.2 Camera and Monitor
One BOSCH AutoDome camera, with RS232 control, can be connected to the CCU. One or more
video displays can be connected to the camera output. These video displays must accept video signals
according to the PAL-B or NTSC standard as provided by the AutoDome camera.
NOTE: If the distance between camera and CCU or PC is more than 15 meters the RS232
signal must be converted to Biphase with an LTC 8784/50 converter. (For connection refer to
FIG 6-4).
6.2.3 Installation
FIG 6-4 shows the required cables for the following connections:
1. Single CCU to AutoDome camera.
2. DCN control or temporary PC to CCU.
3. DCN control or temporary PC to AutoDome camera.
4. DCN control or temporary PC to CCU and AutoDome camera (2 COM ports)
5. DCN control or temporary PC to AutoDome camera via LTC 8784/50 data converter.
CAUTION: To meet EMC requirements all connections made to the ‘Port 1’ output of the
CCU LBB 3500/05(D) or ‘Port 1’ and ‘Poet 2’ of the CCU LBB 3500/15(D) or LBB 3500/35(D)
must be screened cables, where at least one side of the screening is connected to ground.
