hardware settings
The C8189 does not have front panel controls. It may be configured via a DIP switch and a rotary encoder. On the front panel there are two LEDs with different display modes:
STATUS
green = status OK flashing = the module is under control of the Frame Controller red = status is bad, remote reading of the status via GUI is required.
It is likely that the Frame Controller has issued a SNMP trap.
MASTER
Off = the audio bus interface clock must be provided by the frame red = the 8188 is clock master for the frame

BUS-EN: ON automatically connects the outputs to the C8k audio buses on power up.
The output configuration will be taken from the NV (non volatile) memory. OFF
disconnects the module outputs from the C8k buses on power up. MASTER: ON
the module is clock master for a C8932 frame
OFF an other module is sync master for the frame
#3 not used ID +16 ON
CAN address range is extended by +16, counting from 0x10 to 0x1F
(16 – 31)
OFF CAN address ranges from 0x0 to 0xF (0 – 15)

ADDRESS 0 – F sets the CAN ID . The 16 switch positions are hexadecimal numbers (0x0
to 0xF). Each module within a frame must be assigned a unique CAN bus address for proper communication with other modules of the frame.
Important note! To avoid audio bus conflicts when you replace a module or install an additional one and the configuration is unknown, the output bus drivers must be disabled by BUS-EN=OFF 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.
INIT the button initializes the module to factory default if one holds it down
while power up.

Relay Bypass the AES I/Os provide a relay for each pair, which may be turned off with
Relay Wait Time the Relay Bypass is active as long as the module has no power. After Power Up If power is turned on, the module will wait this amount of time before
this switch, i.e. the I/Os are put in Relay Bypass mode.
the relays are engaged to disable Relay Bypass.

MASTER SELECT if the module is turned into Master mode by SW1, you may select here
one of the four AES inputs as the actual MASTER input. In this case the clock reference of that input will be used to synchronize the whole C8932 or an island of the C8934 frame.
Important note! For a C8932 frame the C8189 must be placed into one of the slots marked red and no other sync source (e.g. C8830) must be installed.
Sample rate Converter it is possible to turn on a SRC for that AES input. to C8000 Bus here you assign the audio signals from the AES inputs to c8k busses
8ch Mux sends all 4 signal pairs on one bus line
Ch 1/2 … Ch 7/8 sends a pair of input signals to one bus line Enable Bus Drivers turns on all module bus drivers (from tri state mode to active). from C8000 Bus here you assign the signals from the c8k bus to the AES outputs
8ch Mux receives 8 channels from one bus line. The assignment of pairs to the
AES outputs must be done by the respective check boxes
Ch 1/2… Ch 7/8 receives a pair of signals from the c8k bus Transparent Status Bits if not checked the Channel Status of the AES transmitter will be set to:
Format : Professional Audio Mode : Audio Emphasis : None Freq. Mode : Locked Sample Freq. : 48kHz Channel Mode : Not Indicated User Bits : None Auxiliary Bits : 24Bit Audio Word Length : Not indicated
AES Input Error Detection the status of the AES inputs can be monitored for AES signal present
and for 3 detailed error types:
Lock AES receiver lock status Validity AES3 validity bit detected
Parity AES parity (data errors detection) You can mask each AES input for error detection: grey - error detection disabled
green - no error detected / PCM audio yellow - no error detected / non audio (Dolby E, D) red - indicates an error condition.
Bus Error Detection 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, input module, other DSP module). The Error Detection can be turned Off and On for each input from the bus. You will see the Bus Status on the left hand side as a soft LED.
grey - error detection is disabled
green - no error detected / PCM yellow - no error detected / non audio (Dolby E, D)
The bus status may also be presented to external monitoring systems
red - indicates an error condition.

GPO
C8000
C8189
GPOs (Tallies) may signal the status of a module by means of relay switches. Those
relays have NO (normally open) as well as NC (normally closed) contacts. This allows easy interconnection with more generic monitoring equipment. If an event occurs the C8189 puts the assigned number on the CAN bus so a C8817 GPI/O module or the brc8x may turn on a relay or button LEDs (see C8817 manual for details).
