Dcn-ddb is a kind of printed circuit board, which can be used

 with a variety of digital devices (such as hall display, recording system and camera controller) to provide data communication link to the new generation of DCN. Transparent data transmission can be performed between the data communication boards in the new generation DCN system, such as remote projector, lighting, shading, projection screen, etc. It is suitable for installation in external devices and contains an RS232 communication port with a baud rate of 9600 or 1200 (selected by on-board dip switch). Optocouplers isolate them from the next generation of DCN systems. It can be powered by a new generation of DCN system or by an external power supply. Another function of the system is to control the indicator light to show the interpreter's request for speed reduction and help. When the interpreter presses the slow down or help button, the system activates another output control of the DDB, which controls the indicator light at the chairman's or operator's position. Basic function control and indicator light · initialization button interconnect assembly with LED indication · 2 m (78.7 inch) cable with molded six pin circular connector at the end · multi pin PCB connector for: – external initialization button and LED indicator light – 8-bit parallel data input and output · 9-pin Mini d-jack for RS232 output technical specifications electrical External power supply 7.5 – 35 VDC mechanical dimensions (H x W) 100 x 200 mm (3.93 x 7.87 in) order information DCN ￣ DDB data distribution board is used to provide the data communication link to LED display screen of the new generation of DCN system data distribution board.
