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

switch settings

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)
