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.

STATUS DISPLAY
If you are controlling a specific module you will see a status frame on the left
hand side that also appears if you hover with the mouse over the graphical boxes
in the GUIs OVERVIEW display. If the GUI size does not fit your screen well you
may decrease the size of the status display by clicking on the little arrows in the
upper left edge to get a smaller view.
If you click on the "metering" symbol
in the bottom of that display, an applet
will be downloaded from the frame
controller, that shows the level display :
A JAVA Runtime Environment must be
installed on the PC to run that applet.
The metering data will be streamed
via UDP protocol to the PC.
Make sure that you have opened the Windows fire wall
for the required UDP port (see C8702 manual for details). If no UDP data are received by the applet,
the meters will turn red from black. Since Java SE 7u21 an applet must be signed with a trusted
certification. Junger Audio has certified its applets. You must have at least C8702 frame controller
firmware 1.17.x in order to get it right. Details from ORACLE you will find here :

SETUP (Operating Mode = 5.1 + 2)
For the 5.1 + 2 operating mode (selected at the DSP pane) the 8 processing channels will be shared
between a surround (5.1) and a stereo program. If the 5.1 downmix is activated the outputs 7/8 will
be occupied by the output of the downmix block and no extra stereo program processing will be
possible.
Here you can configure the DSP input assignment
of the surround processor and the operation of the downmix unit (pre / post 5.1 level magic)
as well as the input selection of the 2 channel (stereo level magic) audio processor.
You may change downmix parameters :

About "MixMux" : You may select if the input audio signals to the C8086+ must be taken from a
source that delivers it in 8 channel (time division) multiplex (Mux) or in 2 channel (time division)
multiplex or you may select a mixture (Mix) of both formats.

Error Detection [Off / On]
the serial audio data from the frame bus can be monitored for
proper positioning of an Error-Flag. A bad Error-Flag is an
indication that there is disturbance upstream (input signal lost,
input module broken, non audio signal).
The Error Detection can be turned Off and On in general and
individually for each pair of input channels. You will see the
status of the busses on the left hand side :
“Bus Status”.
A grey “LED” shows that the detection is disabled. While green
is OK, red indicates an error condition. In addition this display
indicates if the signal is linear PCM or non audio. In case of non
audio the soft LED becomes yellow and "NON AUDIO" will be

via SNMP. The frame controller summarizes such status
information and generates SNMP traps for the frame as an
entity or may activate GPOs (if GPI/O module(s) are installed).
The SNMP manager may afterwards poll the “modulesStatus”
for more detailed status information per input (see SNMP
documentation for details).
GPIs are useful if you want to recall settings (e.g. by loading of a presets) or turn functions on or off
remotely. A C8k frame can handle 127 independent virtual GPI numbers. You must assign a unique
number to the respective preset / function. Such numbers will be generated by the brc8x Broadcast
Remote Controller or by the C8817 GPI/O interface module. If the C8086+ receives such a number
via the CAN bus, it will for example load the respective preset.

GPOs are meant to present status information to external devices. A C8k frame can handle 127
independent virtual GPO numbers. You must assign a unique number to the respective
preset / function. In case a preset is loaded either manually via the GUI or remotely via the
brc8x or via a GPI/O module, the assigned number will be broadcasted over the CAN bus.
A GPI/O module which has that number assigned to a physical output will engage that relay or a
brc8x may turn on an assigned button tally light.
Clear GPO on If a GPO indicates that a certain preset is loaded and if you
Preset modified change parameters which are related to that preset the word
"modified" will be displayed in line with the preset name in the
status window.
In this case you may clear that GPO to indicate that the
parameters are not the same as the content of the previously
loaded preset.
Important Note! GPOs from modules and GPIs to modules don't "see" each other.
I.e. you can't use a status GPO of module A to load a preset for module B by simply assigning
a GPO number of module A as a GPI number of module B. If this is a requirement you
must involve the GPI/O conversion function of the C8817 GPI/O module (see manual for details).
