1. DCU12 Installation
The DCU12 combines a high resolution 12 inch screen and a keyboard into a compact
layout . The DCU12 needs to be connected to a MFDBB processor unit (this is not a self
contained unit like the MFD12 or MFD8). The DCU12 can be used with or without the
MCU001 (MFDBB Keyboard).
To connect the DCU12, you must use a 4 Pair ethernet cable and a DVI Cable.
The DCU12 Ethernet cable must be connected to either Port 1 or Port 2 of the MFDBB
processor unit.
Ethernet Cables that can be used to connect the DCU12 to Port 1 or Port 2 of the
MFDBB Processor:
- 2 Meter RJ45 to RJ45 Ethernet Cable (P/N 000-167-175)
- 5 Meter RJ45 to RJ45 Ethernet Cable (P/N 000-167-176)
- 10 Meter RJ45 to RJ45 Ethernet Cable (P/N 000-167-177)
Furuno offers the following DVI cable to connect the DVI output of the MFDBB
processor to the DVI input of the DCU12:
- 5 Meter DVI Cable (FUSA P/N= 000-149-054)
- 10 Meter DVI Cable (FUSA P/N= CBL-DVI-10M)

The MFDBB processor unit has an Internal Hub that is compatible with Power
Synchronization. DIP switches inside the processor unit can be turned ON or OFF to
enable/disable the Power Synchronization feature. The number on each DIP switch
corresponds to the port number.
When connecting the DCU12 to the MFDBB processor, you must use Port 1 or Port 2.
Make sure that the corresponding DIP switch inside the MFDBB is turned ON.
Note: Refer to the MFD Installation Guide for more information on Power
Synchronization

2. DCU12 /Processor Linking
The DCU12 is an Ethernet Control Unit network device that needs to be assigned
(linked) to a specific MFDBB processor unit during installation. A special “key-push”
sequence is used to cycle through the “Linking Codes” for all the MFDBB processor
unit(s).
If only one MFDBB processor unit is on the Network:
Simultaneously press and hold the Left key of the Scrolling Pad, the Right key of the
Cursor pad and push the RotoKey for 5sec. (This intentionally requires two hands)
The DCU12 will beep two times. You can release the button at this time. The DCU12
will now control the MFDBB.
Note: If this process fails, make sure that one MFDBB is set as Master on the network.
Disconnect and reconnect the DCU12 from the processor unit and try again.
If multiple MFDBB Processor Units are on the Network:
Make sure that all MFDBBs are ON and are displaying the Main Interface (or the
Agreement Box). Repeat the process (as explained above) until two beeps are heard.
Push the RotoKey and/or use the scrolling pad to see if the MFDBB you are looking to
can be controlled with the current DCU12.
If the MFDBB does not respond (This means that the DCU12 is actually linked to
another processor unit on the network), repeat the process until the DCU12 controls the
correct MFDBB processor.
Repeat this process to link the other MFDBBs to their corresponding DCU12.
