Audio Delay : 16 times 0 ...320 msec

GENERAL :
Backplane connector : ref. to DIN41612, 64pin, a+b, male

Important Note! Do not place the C8405 close to either the power supplies or the side panel of the c8k
frame. Due to the high density of hot components on the PCB you may otherwise overheat the module.

C8405

initial set up / bus assignment

For the initial setup the CAN address selection is the most important setting. To avoid address conflict
with other C8k modules the CAN address setting must be done with care.
See C8k System manual for details.

The MASTER MODE is important if the C8405 must deliver the audio clock for signal distribution within
the C8k frame.

The BUS-EN switch controls the driver circuits when power is turned on. This allows you to insert a new
module into an existing system without the risk of disturbing signals on other busses if the drivers are
disabled when the module is inserted into a frame with unknown bus configuration.

INIT Pressing the INIT button during power up will initialize the module

ADDRESS Set the CAN ADDR rotary encoder to an address, which is not in use by

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

parameters to factory default values.

see C8000 system manual).

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.
