System architecture

NMEA 2000® device connection

All devices connect to the network via a Micro-C connector.

Essential network information

• The network consists of a linear “backbone” from which “drop cables”

connect to H5000 and NMEA 2000 devices

• H5000 products use Micro-C style connectors, this allows

compatibility with NMEA 2000 networks.

 Note: Some B&G products use Simnet proprietary connectors, but are

compatible via adaptor cables.

• A single drop cable has a maximum length of 6 m (20 ft). The total

length of all drop cables combined should not exceed 78 m (256 ft)

• The network has a maximum cable length of 100 m (328 ft), between

any two terminators

• The network needs to have a Micro-C Terminator at each end of the

backbone. A Micro-C Terminator can be one of the following:

• A Micro-C Terminator blank plug

• A 508 model wind transducer (where the mast cable is one end of

the backbone)

Planning and installing a network backbone

The network backbone needs to run between the locations of all

products you want to install, typically in a bow to stern layout, and be

no further than 6 m from a device to be connected.

Choose from the following components to make up your network

backbone:

• Micro-C interconnecting cables

• Micro-C power cables - with or without termination

• T-connectors. Use at locations where you want to connect a device by

drop cable

 Note: If using a 508 wind sensor connected directly to the network,

the mast cable should be connected as the  nal length of cable at

one end of the backbone, as the sensor is  tted with a termination

resistor.

 Note Most NMEA 2000 devices can be connected directly to the

network backbone. Simnet devices can be connected to the Micro-C

CAN bus backbone by using adapter cables.
