Furuno 12bb Marine GPS System User Manual


 
Why use the Furuno HUB (HUB101):
The Furuno HUB101 allows the Power Synchronization signal to reach the MFDs and
other Power Synchronization compatible devices. Here is a list of all devices that
support Power Synchronization:
- All NN3D Displays: MFD8, MFD12, MFDBB
- All NN3D Radar Power Supplies: PSU012 and PSU013
- Sounders: DFF1 and DFF3
- HUB101
Note: the DRS itself does NOT need the Power Synchronization Signal as its power
comes directly from an MFD or a PSU. These units provide the Power to the DRS
directly.
Here is a list of all devices that are not compatible with the Power Synchronization
Signal (ignore):
- BBWX1
- DRS antenna (only the PSU needs the Power Synchronization signal)
- BB Keyboard (MCU001)
- FA30 and FA50
- FAX30
- BBFF1 and BBFF3
- Computer
The Power Synchronization signal is transmitted using a normally unused wire of the
Ethernet Cable (PIN 4 and Pin 5) thus a “4-Pair” Ethernet cable must be used to
connect Power Synchronization compatible device. If a regular Ethernet switch is used
instead of the Furuno HUB101, “2-Pair” Ethernet cables must be used between each
MFD and the generic Ethernet Switch so that the Furuno Power Synchronization signal
does not interfere with or harm the Ethernet Switch. Furuno offers a 3 meter 2 Pair
Ethernet cable (FUSA P/N= 000-167-171).
Note: The Power Synchronization signal is only used for starting up the system. The
shutdown is an Ethernet software command and thus will also work with a regular HUB.
