Configuration of a C8000 frame

The C8k frame holds the cards physically. They are electrically connected to the back plane of the frame by a

64pin connector. The back plane distributes 5V power, several clocks, the CAN-bus, a few status and

address signals as well as the digital audio data from and to processors or I/O devices.

Audio bus line assignment:

32 audio bus lines S01 to S32 are used for the distribution of digital audio data. The majority of the modules

use the same 2ch format, i.e. 2 audio channels are multiplexed on to one output. Considering a 2ch

processing (DSP) module, one needs 1 of these 32 lines to connect an input device (e.g. AES IN) via Sx to

the processing module (DSP) and one line to connect the output of the DSP module to an output device (e.g.

SDI embedder) via Sy.

There is no rule how to use the 32 lines with one exception:

! You must not connect more than one device output to a bus line at a time. If you connect more than

one device output to a bus line, you will destroy the audio signal.

But you can connect as many device inputs as needed to one device output

(e.g. for signal distribution or signal conversion purposes).

Each of the legacy modules has rows of jumpers to connect its output(s) to one of the 32 bus lines.

Some modules have more than one input / output so they need more than 2 bus lines to connect to other

devices.

At the module input side we have different solutions. Old devices also have rows of jumpers to connect to a

bus. Newer devices will select the relevant bus line by an electronic routing circuit.

You must tell it by one or more rotary encoder(s) from which bus line it should gather the audio data.

Newer devices like the C8402/03/04/05 (SDI Embedder / De-Embedder), the C8086+ (8 channel

LevelMagic), C8082 (5.1 fail over / switch over / ducking) as well as the 8305/06 (new MADI I/Os) and

8601/11/12 (Dolby Encoder / Decoder modules) and their successors C8621/31/32 have electronic output

routing also and the ability to multiplex 8 audio channels on one bus line. This increases the density of the

audio bus system dramatically. Such devices are backward compatible because they can also send and

receive 2 channels per bus line. See an example of such module carrier boards further below.

Please refer to the respective manual for details.

Below is an example of a module carrier board for an old processing module:

On the left hand side you see the rotary encoders. They have 16 settings (0 to F) to select one of the

bus lines S1 to S16. If you need access to bus lines higher than 16, you must replace the adjacent range

jumper labeled: “+16”. Now the rotary encoder will select bus lines S17 (0) to S32 (F).

For two channel devices the rotary encoder labeled “IN-1” and jumper row labeled “OUT1” are used. For 4

channel devices the rotary encoders labeled “IN-1” and “IN-2” and jumper rows labeled “OUT1” and “OUT2”

are used, and so forth.

! On some modules the IN4 rotary encoder and the range jumper are used to setup special

application modes (see respective manual for details).

Below is an example of a module board of a newer generation processing module - C8086:

Since this type of module has an electronic output routing facility, great care must be taken when installing or

exchanging a new module for an existing system!

DIP-switch #1 (no label) serves for the CAN address “+16” selection. If it is set to ON, the range for the

CAN address rotary encoder lasts from 0x10 to 0x1F.

If a frame controller is installed, the DIP-switch #2 must be set to REMOTE=ON. All settings after power up

are taken from an NV (non volatile) memory and the remote control via the Frame Controller is enabled.

Otherwise a basic configuration will be taken from the settings of the I/O and MODE rotary encoders if

implemented (see individual module manuals for details).

If the above DIP-switch #3 is set to BUS-EN=ON, the bus configuration will be taken from the

NV memory after power up. If an unknown bus configuration is stored, it can cause a conflict with other

modules inside the frame (short cuts between several outputs).

Important Note! If you are not sure about the output bus configuration you must turn BUS-EN=OFF before

inserting such module. Now all bus outputs are in Tri-State-Mode (i.e. off).

You can use the frame controller to configure the board. The configuration will automatically be stored into

the NV memory. For testing purposes you may temporarily enable the bus drivers via the GUI.

To enable the configuration for the next power up you must pull out the module and set BUS-EN=ON.

DIP-switch #4, TDM=ON enables the multiplexing of eight audio channels on one bus line on the first

available audio bus when not in REMOTE mode.

Nearly the same applies to the C8402/03/04 SDI Embedder / De-Embedder with slightly different

DIP-switch labeling:

The MODE DIP-switch allows for setting of the operating modes:

If DIP-switch #1 is set to MASTER, the module provides the necessary clocks for audio signal distribution for

the C8k frame. In this case the Sync-Module must be removed!

You must use the frame controller to configure the board. Therefore the DIP-switch #2 must be set to

REMOTE=ON. All settings after power up are taken from an NV (non volatile) memory and the remote

control via the Frame Controller is enabled.

If the upper DIP-switch #3 is set to BUS-EN=ON, the bus configuration will be taken from the

NV memory after power up. If an unknown bus configuration is stored, it can cause a conflict with other

modules inside the frame (short cuts between several outputs).

TDM=ON enables the multiplexing of eight audio channels on one bus line.

The CAN/BUS DIP-switch determines the CAN-bus address of the module in hexadecimal values

from 0 – F. The coding is binary (D0=LSB, D3=MSB).

Older versions had a few more DIP-switches for hardware based settings of the Embedder and

the De-Embedder.

And finally here you see the actual design of a c8k module here from the compact C8492 module,

the 16 channel SDI I/O processor with optional bus access:

As a new feature you see the CAN-H switch above. That allows the module to operate with 1Mbit/s

CAN-bus speed. This speed enhancement is helpful if you must log multiple programs from multiple C8492s

in a compact 64 or compact 256 frame.

Since only a selected number of modules will support the higher CAN-bus speed, grate care must be taken

when setting up such a frame. All modules on the same CAN-bus must run on the same CAN-bus speed!
