Maretron NETWORK BUS EXTENDER NBE100 用户手册

 

 

The NBE100 is installed on an NMEA 2000

®

 network between the two sections that you wish 

to physically isolate. There is no electrical connection through the NBE100, so you must 
ensure that each of the two NMEA 2000

®

 networks connected to the NBE100 must have 

separate power sources and two termination resistors. This means that if you use an NBE100 
to split an existing network into two separate networks, you must provide one additional power 
connection and two additional termination resistors (one for each side of the NBE100).  
 
The two NMEA 2000

®

 connectors are labeled “N2K PORT A(PWR)” and “N2K PORT B”. 

Logically, these connectors are identical; that is, you can connect the NBE100 between two 
networks in either way and it will function identically. However, the NBE100 sources power 
only from the connector marked “N2K PORT A(PWR)”. It uses no power from the connector 
labeled “N2K PORT B”. 
 
Figure 3 below shows the installation of an NBE100 into a simple NMEA 2000

 network. 

 
For exceptionally large networks, multiple NBE100’s may be used to segment the network into 
more than two segments. Each segment must have its power connection and two termination 
resistors.
