A controllable camera that is switched through a switcher can either be controlled through the switcher or directly from the VMX300(-E)
workstation. If you want to control the camera through the switcher, connect the camera’s data line to the switcher (refer to Figure 4). If you want
to control the camera from the VMX300(-E) workstation, connect the camera’s data line to the workstation. The video from both cameras is
connected to the switcher.
Figure 4. Two Cameras Controlled by Different Device Drivers
In Figure 4 video and data are transmitted over separate wires. In Coaxitron
®
transmission, however, both video and data are transmitted over
a single coaxial cable, as illustrated by the camera on the left in Figure 5. Fixed cameras, like the one on the right, are not controllable and
therefore do not transmit data.
