Using BLU Link
BLU Link Mastership
BLU link requires one device to provide master clock for all other devices on the bus� BLU link mastership is
automatically negotiated between all devices, and any change to the bus will trigger the auto-negotiation to
restart�
Each BLU link device contains a Master Priority setting, with a possible value between 0 and 254� Some BLU
link devices have a fixed Master Priority setting, while others are configurable� The device with the highest
Master Priority setting on the bus will be configured as the BLU link master� If two BLU link devices have the
same Master Priority setting, then the device's MAC addresses are compared to determine which will be the
master, with the device with the higher MAC address winning�
If connecting to a BLU link bus that requires a certain device to be master, ensure that the master device has
a higher Master Priority setting than all other BLU link devices on the bus�
