switch settings

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 may 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! Since this type of module has an electronic output routing facility, great care must be
taken when installing or exchanging a module when such frame has components which are On Air!
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. If all settings are done remotely and the unit fits into the bus
assignment scheme of that frame, you must remove it and place the switch back into
position BUS-EN=ON.

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

CAN address ranges from 0x0 to 0xF (0 – 15)

CAN ADDR 0 – F

Important note! This address also defines the position of the graphical box of that module within the
GUI if you control the frame via the C8702 frame controller. The absolute position is not important but will

ease the control if you group such boxes for modules processing a certain TV channel.

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

sets the CAN bus address. Each module within a frame must be assigned a

unique CAN bus address for proper communication with the frame controller

and other modules of the frame.

Addresses from “0” to “7” will place the module graphic box 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.

SW1 #4 ID +16 will add an offset to that schema. If it is turned on, a module

with CAN ADDR "0" will appear in place one of the fifth row and so forth.

PRESETS (Example for activated Dolby metadata option)

The C8086+ offers 16 DSP (audio) presets and 8 Setup/Bus Routing presets. Additionally the
C8086+M (metadata option) has another 16 Dolby metadata presets. The status window at the left
hand side shows the names of the active preset. The word “modified” will appear in line with the
preset name, if parameters from the loaded preset were changed.
