Page 2: Installation
C8702 Frame Controller Installation Location of labels and switches on the C8702 module. The default IP address label is located on the “Coldfire” chip of the controller module and on the front panel of the module. While the MAC address is printed on a label here:... -
Page 3: Technical Specifications
After power-up the C8702 checks the CAN bus and automaticlly sets its CAN bus speed accordingly. If by accident one inserts a low speed module afterwards, the C8702 will enter "CAN bus off mode" and will reboot after a while until that module is removed. -
Page 4: Connector Pin Assignments
C8k modules via CAN bus while external applications communicate via TCP/IP over Ethernet with the C8702. The CAN bus is a simple two-wire differential serial bus, it operates in noisy electrical environments with a high level of data integrity. Its open architecture and user-definable transmission medium makes it extremely flexible. - Page 5 STATUS LED lights yellow. Now you may press the INIT button and hold it firmly until the STATUS LED flashes three times. This is an acknowledgement that the C8702 has been initialized to factory default settings (you may also hold down the INIT button at any time until the STATUS LED flashes three times).
- Page 6 2.1 Change the network setting of the PC The PC must be given an IP address from the address room of the C8702 default IP address. The factory default IP address is printed on a label on the controller module (see installation).
- Page 7 C8702 Frame Controller Important Note! If the C8702 has an unknown IP configuration you may initialize it to factory default settings (see above). This will restore the factory default IP configuration. 2.3 Open a browser and enter the default IP address in the URL field: 2.4 On the web site click on the spanner tool...
- Page 8 The GUI is based on common web technologies so you can display it nearly everywhere. External Ethernet based access to the Junger devices is maintained by a dedicated 32Bit communication processor that is part of the C8702 Frame Controller module.
- Page 9 - File download = Enable Important Note! To display bar graph meters the C8702 will launch a JAVA Web Start application. This requires the installation of an actual Java Runtime Environment 8.x (or higher) on the PC. You will get it as a free download from a lot of sites around the world or directly from the license owner Oracle: https://ww.java.com/en/download...
- Page 10 SNMP sysObject OIDs (Object Identifier). Activation of the security feature The web interface of Junger Audio units offers a two tier security schema. * Operators can view everything and load presets. * Administrators can set up C8k frames including their modules.
- Page 11 C8000 processing system C8702 Frame Controller Setting UDP port range for metering In order to receive data for the meter bar graph display, if a local firewall is active, you must open it for the browser application or you must reserve UDP ports (for which the firewall will be held open).

Page 12: Selecting Services
C8000 processing system C8702 Frame Controller Setting of CAN BUS speed You can select between the two CAN bus speeds: Normal (125kBit/s) or High (1Mbit/s) and the Automatic detection of the installed modules. Important Note! Don't mix up modules which are set to different CAN bus speeds. - Page 13 The Frame Controller polls the modules permanently for such status information and sums (condenses) that information for the entire frame. An external monitoring tool (SNMP Manager) may poll the SNMP agent based on the Junger-C8K-MIB-4. The MIB and the associated document can be requested from Junger Audio.
- Page 14 Junger Audio staff. After pressing the <SAVE DIAGNOSTIC FILE> soft button an XML file will be generated. You must download it to your PC and send it to Junger Audio GmbH if requested. Important Note! “Thorough diagnostics” is a more comprehensive procedure that will interrupt audio processing in some of the modules.
- Page 15 C8000 processing system C8702 Frame Controller You must browse for the appropriate image file from the previously unpacked ZIP. Once done you must press the <START UPDATE NOW> soft button. This process has 3 steps. The controller will upload the image file from the PC into its memory, afterwards it will erase the flash memory and finally burn the new image file into it.
- Page 16 If you can not reach the GUI via an actual browser you must do a little trick to update the frame controller. You must reboot the C8702 by briefly pressing the <INIT> button (or rebooting it from the console interface). After approx. 60sec (boot up time) you should open the browser again and enter the URL: http://<C8702-IP-address>/standalone-update.html...
- Page 17 You must browse for the location of the respective file (where you have unpacked the archive or where a single file received from Junger is stored). Important Note! It is not possible to select a firmware file directly from an archive folder.
- Page 18 C8492 are options which may be purchased later and which must be enabled in the field. In order to get the correct licensing file from Junger Audio you must send the Licensing Information file to Junger Audio. You must go to CONTROLLER > SOFTWARE UPDATE > MODULES LICENSING: The table above shows the current license status of an example frame.

Page 19: System Backup And Restore
C8000 processing system C8702 Frame Controller System backup and restore For safety reasons or when doing module firmware updates you may want to backup the on air parameters and presets of the modules in a frame: When you press <BACKUP> the frame controller will gather all information stored in individual modules of the frame and will build an XML file that contains such information. -
Page 20: Hints For Operation
C8000 processing system C8702 Frame Controller Hints for operation The common web technology has many advantages but also a few disadvantages. Most of the information displayed relies on the data the browser receives on demand from the web server of the communication processor, i.e. - Page 21 Frame Controller! Under some circumstances the browser session with the web server of the C8702 Frame Controller will expire. In this case you must reload [F5] or close the browser and start it again in order to open a new session.
- Page 22 C8000 processing system C8702 Frame Controller Monitoring the processing status of a processing module The major parameter of the audio processing is the momentary GAIN of the module. This gain is permanently changed by an adaptive dynamic process like LevelMagic™. If this gain sticks at one end of its working range for too long, the settings of the processing parameters should be checked.
- Page 23 Now the Junger processing channnel may be set up to Bit Transparent mode = [off / on / auto]: In "auto" mode the module detects the non audio flag and will then pass the stream through the processing module without touching it to avoid damage to the data structure.
