3.5 Communication
Call button
Press this momentary button (4) to send a signal to the control panels calling for
attention. The ND/RE indicator in the 1.5-inch viewfinder shows when a call signal is
sent or received.
Data channel
The Aux connector on the side of the adapter provides analogue control signals and
facilities for the connection of a two-way private data channel between camera and
Base Station. In the Install menu, the tracker microphone and engineering intercom
channels can be selected to carry the private data instead of their normal function.
On-air signal
The tracker connector on the side of the adapter, as well as providing full intercom
facilities for the dolly or crane driver, also carries a tally signal and a +12 Vdc power
supply. This allows an external on-air lamp to be used.
