hardware settings

The C8087 does not have front panel controls.
It must be configured via web browser and the C8702 Frame Controller.

C8087

Above is a schematic view of the PCB . You must set these switches carefully in order not to disturb the
audio signal of other parties within a c8k frame.

The module has a front panel STATUS LED. It shows green if the module is working correctly. It turns red
if something is wrong and it flashes if the module is under remote control (in focus).

5.1 Upmix

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

SW1
1: BUS-EN ON
the output configuration will be taken from the NV (non volatile) memory
after power up.
OFF

will set all bus outputs to Tri-State-Mode (inactive). Now you can use the
frame controller to configure the board. This configuration will automatically
be stored into the NV memory. To enable the configuration for the next
power up you must pull out the module and set BUS-EN=ON again.

Important note! If an unknown output bus configuration is stored, it can cause a conflict with
other modules in the frame. If you are not sure about the output bus configuration you must turn
BUS-EN=OFF before inserting such a module into a system that is On Air.

2: Not used OFF
3: Not used OFF
4: ID +16 ON

CAN address range is extended by +16, ranges from 0x10 to 0x1F (16 – 31)
OFF
CAN address ranges from 0x0 to 0xF (0 – 15)

SW2
CAN rotary encoder 0 – F

sets the CAN bus address. Each module within a frame must be assigned a
unique CAN bus address for proper communication with other modules of
the frame (see also ID +16 above).

Important note! This address also sets the position of the module graphic when you control the
frame via the web GUI by a C8702 frame controller.

Addresses from “0” to “7” will place the module graphic into the third row
(first row shows the frame controller and sync modules, second row is
empty). Addresses “8” to “F” will place it into the fourth row and so on.
I.e. address “0” will place it in upper left position of row 3, while “1F” will place
it in lower right position of row 6.

SW3
INIT pressing the INIT button during power up will initialize the module parameters

to factory default values.
