nmea interface
The National Marine Electronics Association (NMEA) is an American organisation which has defined a number of
standard specifications for the interconnection of marine electronic instruments. These standards specify the
electrical signals and the format of the data that is transferred. This allows equipment such as the h1000 to
communicate with other manufacturers equipment.
The Universal Interface is an NMEA interface specifically designed to allow the h1000 system to "talk" with other
manufactures equipment. The most likely devices that will be connected to the Universal Interface are position
fixers such as GPS's and Chart Plotters. The connection of navigational data to the h1000 Instrument allows this
data to be displayed on the system and creates new calculated functions such as tide rate and direction.
The Universal Interface has one NMEA Input Port (receive) and one NMEA Output Port (transmit) and are designed
to comply with the latest NMEA 0183 standards. The Universal Interface also contains the connections for an
external alarm output.

System components share data together via a common Fastnet
databus and are supplied with bayonet connectors for ease of
installation. A selection of cable lengths are available with options for
straight and right angle connectors to suit most requirements.

To prevent the occurrence of voltage drops on larger systems, the
power supply to the system should either be placed mid-way or at both
ends of the Fastnet
system, it is recommended that the 4-Way Hub be used. The 4-Way Hub
offers two advantages. The first advantage is that it offers a convenient
entry point for power onto the system. The second advantage is that it
conveniently allows the system to be branched to reduce the overall
length of the system. The correct selection of Fastnet
