location of switches:

C8685

initial set up / bus assignment

For the initial setup the CAN ADDRESS selection is the most important setting. To avoid address conflicts
with other C8k modules the CAN address setting must be done with care, because each CAN address
has to be unique! See C8k System manual for details.

The Dip-Switch #4 serves as +16 address range extension for the CAN address switch.
The Dip-Switch #1 is the BUS-EN switch which turns the audio driver circuits on 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 actual bus configuration is unknown.

The INIT button will initialize the module to factory default if one holds it down while power up.

switch settings

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

SW1 #2 not used

SW1 #3 not used
ID +16: ON

CAN address is extended by +16 (counting from 0x10 to 0x1F)

OFF
CAN address is standard (counting from 0x0 to 0xF)

Important note! To avoid audio bus conflicts when you replace a C8685 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.

rotary encoder settings

ADDRESS: This rotary encoder sets the CAN ID of the C8685. The 16 switch positions

are hexadecimal numbers (0x0 to 0xF).

remote control operation

- Web-server based remote control of parameters via frame controller C8702

- 3rd party remote control by http protocol based API
(please contact Junger Audio for details)

- Hardware GPI/O control of preset operation and special module functions

- Remote control by the brc8x Broadcast Remote Controller via CAN bus
