Introduction
The DCN-DDB is a printed circuit board that is used with
digital equipment such as hall displays, recorder systems
and camera controllers to provide the data communication
link to the DCN Next Generation. Transparent data transport
between data communication boards in the DCN Next
Generation system is possible, i.e. for remote control of
slide projectors, lights, blinds, projection screens etc. It is
intended for mounting in external equipment, and includes
an RS232 communication port with a baud rate of 9600 or
1200 baud - selectable by an onboard dip switch. Opto-
couplers isolate it from the DCN Next Generation system. It
can be powered by DCN Next Generation system supply or
an external power source. Other function is to control
indicators to show speak slowly and help request from
interpreters. When the interpreter presses the speak slowly
or help button another output control of the DDB is
activated, which can control an indicator of the chairman or
operator’s position.
