Network

2.6.1. Introduction

NavNet3D (just like NavNet1 and VX2) uses standard TCP/IP Ethernet to share
radar/sounder images and other navigation information from devices connected within a
networked system. In any single NavNet 3D network, a combination of UP to TEN
NavNet3D MFDs may be networked together. All NavNet3D Network Components have
one integrated regular RJ45 Ethernet port (with the exception of the MFDBB which has
an integrated hub). Legacy NavNet components such as the ETR-6/10N (FUSA P/N
BBFF1) or ETR-30N (FUSA P/N BBFF3) network sounder will need to be connected
using the Hub Adapter Cable 6 Pin to RJ45 (FUSA P/N = 000-144-463).
AUTO MDI/X - All NN3D MFDs, DRS and the HUB101 incorporate automatic straight
and cross-over Ethernet Cable detection and switching. Therefore any combination of
straight and cross-over Ethernet Cables can be utilized when installing network cabling.
MFD8/12
The MFD8/12 has one Waterproof Ethernet Port on the rear of the unit. It comes with
standard supply of a 3 meter Ethernet Cable (FUSA P/N =000-164-809) terminated at
one end with a Waterproof connector and at the other end with a regular RJ45.
This cable can be extended using a coupler (FUSA P/N= RJ4-5CN-STR) and a regular
Ethernet Cable. Please note that the coupler is not waterproof and thus needs to be
installed accordingly.
MFDBB
The MFDBB Processor Unit contains an integrated hub that provides 4x Ethernet ports.
Two of these ports are exclusively dedicated to the keyboard (control unit MCU001)
connection. The MFDBB keyboard must be directly connected to one of the dedicated
Ethernet ports on the BB (the MCU001 Control Unit cannot be connected to an Ethernet
Hub/Switch). The Keyboard comes standard with a 5 meter Ethernet cable, but other
lengths may be used:
- 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)
Note: The Keyboard uses the Ethernet cable for both Power and Data. Do not plug
anything else beside the Keyboard in Ethernet Port 1 or Port 2 on the MFDBB. These
two ports are NOT standard POE (Power over Ethernet) and POE devices cannot be
connected to these two ports.
