Using BLU Link
Connecting to the Web-Server App
To connect to the DCP-555's built-in web-server app and begin configuring the device:
1� With the control device connected to the same network as the DCP-555, launch the browser of choice and
enter the DCP-555's IP address in to the browser's address field�
2� Enter administrator for the password and then select Sign In�
3� Once logged in, you can change the password by clicking the User icon in the upper right-hand corner
of the window�
See the DCP-555 control app help for information on configuring the DCP-555�
Using BLU Link
BLU link is a proprietary point-to-point digital audio bus that supports up to 256 audio channels at 48kHz or
128 audio channels at 96kHz� The DCP-555 supports 28x32 channels of BLU link audio at 48kHz�
NOTE: The BLU link sample rate for all devices on a BLU link bus must be configured to match� The DCP-555
has a fixed sample rate of 48kHz, so all other BLU link devices connected to the bus must also be configured
for 48kHz operation�
Making BLU Link Connections
The physical BLU link connections are made using Category 5e or higher cabling connected from the BLU
link OUT port of one device to the BLU link IN port of another device� Additional devices should be connected
in a daisy-chain topology� Redundancy can be provided by completing the loop and connecting the BLU link
OUT port from the last device to the BLU link IN port of the first device� The maximum cable length between
devices cannot exceed 100m/328ft� The BLU link audio bus supports a maximum of 60 BLU link nodes�
NOTE: DO NOT connect BLU link ports to network peripherals, such as a network hub, switch, or router�
Since BLU link is not an AoIP protocol, such devices are not supported and BLU link audio will not pass
through them�
Fault Tolerance
When the last BLU link device in a system is connected back to the first, the BLU link bus is capable of a
degree of fault tolerance since each device receives the same audio from two other devices� If a single cable
connection is broken, the devices which are no longer connected will detect the cable break: one device will
detect that its BLU link IN port is disconnected and the other will detect that its OUT port is disconnected� The
devices will then re-route the audio so that it can again pass through the bus�
NOTE: When the cable is broken, the audio will take longer to reach its destination� This small added delay
is not compensated for in any way, but is a side-effect of the way the fault tolerance system functions�

Page 13 DCP-555 Installation Guide
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�

problem�
NOTE: The green LEDs light to indicate the ports have established a link with the BLU link bus�

Page 15 DCP-555 Installation Guide
Using the USB Port
Using the USB Port
The DCP-555's USB port can be used to transfer audio between the conferencing system and software codecs,
such as Skype®, GoToMeeting™, WebEx®, etc� This port is USB Audio Class 1 compliant, so it supports the
standard WDM driver in Windows® and Core Audio driver in macOS® and doesn't require any additional
drivers to be installed� This port supports 2x2 audio channels (one stereo pair in and out)� Simply connect the
DCP-555 USB port to the computer then select it as the sound input and output device in the computer�
If additional USB ports are required or the DCP-555's USB port is not accessible due to installation location,
up to 4 BSS BLU-USB interfaces can be connected via the BLU link ports� Visit https://bssaudio�com/en/
products/blu-usb for more information on the BLU-USB�
NOTE: To use the BLU-USB with the DCP-555, the BLU-USB must be set to USB Audio Class 1 mode, which
is the default mode� This is indicated by a cyan-colored USB port LED on the BLU-USB� If the BLU-USB's
