switch settings
INIT Pressing the INIT button during power up will initialize the module
parameters to factory default values.
ADDRESS Set the CAN ADDR rotary encoder to an address, which is not in use by
another module of a C8000 frame (for details regarding CAN addressing,
see C8000 system manual).
SW1
1 = ID +16 ON
CAN address is extended by +16 (counting from 0x10 to 0x1F)
OFF
CAN address is standard (counting from 0x0 to 0xF)
2 = Not Used OFF
3 = MASTER: ON
The C8405 is clock master for the C8000 system
Important note! In Master Mode the C8405 must be inserted into one of the red color coded slots of
the C8k frame. Any other sync module must be removed from the frame in such a case!
For the C8934 Split-Frame there is no special slot.
OFF
Standard operation, no special care is needed
4 = BUS-EN: ON
Connects the outputs to the C8k audio buses on power up
OFF
Disconnects the module outputs from the C8k buses on power up
Important note! To avoid audio bus conflicts when you replace a C8405 or install an additional one
and the configuration is unknown, the output bus drivers must be disabled before inserting it. If all
settings are done remotely and the unit fits into the bus assignment scheme of a frame, you must
remove it and place the switch back into position BUS-EN=ON.
SW2
1 = Not Used OFF
2 = Not Used OFF
3 = Not Used OFF
4 = HD progressive
switching mode ON
for progressive HD formats carrying Dolby E signals, it is mandatory to switch
only every second HD frame, because a Dolby E data frame spans over two
progressive video frames. Otherwise one may cut the Dolby E data frame
present at the switching moment in the middle resulting in audio noise after
decoding. Dolby recommends to use a synchronous BB as a reference for
the switching point. In this case the system must be synchronized by a C8830
and the C8405 must not be set to master mode!
In addition to that, SW2-4 must turned ON to use the V-sync derived from the
BB to act as the switching point reference for the internal matrix as well,
instead of the SDI frame reference itself.
