The maximum distance for any device from the bus is six meters, the maximum backbone cable length is m ft. NMEA is used to create a system of connected electronic devices, typically amongst marine instruments, on a marine vessel. Instruments that meet the NMEA standard are connected to one central cable commonly known as a backbone along with other corresponding connectors called t-connectors and drop cables. The backbone serves as a central link between all devices connected to the network by powering each instrument which then relays digital information throughout the entirety of the system.
This allows display units to showcase a multitude of information simultaneously and instruments to work together without conflicting since they share the same corresponding data. If a unit fails or is unresponsive the whole network still communicates information amongst the marine instruments connected.
The NMEA network operates on a volt DC power; connectors with positive and ground wires with inline fuses for the positive wire will allow you supply onboard power to the backbone of the network. These power cables should be connected near the center of the backbone in order for the system to function properly. Common examples of marine instrumentation compatible in the NMEA network include GPS receivers, auto pilots, wind instruments, depth sounders, navigation instruments, engine instruments, and nautical chart plotters.
The inter-connectivity among instruments in the NMEA network allows systems to use data from another instrument on the network as input for actions or displays. For example, the signals from the GPS receiver can be used to correct the course for autopilot; or engine RPM and fuel injection rate can be used to calculate the amount of fuel you have left.
KUS has been designing and manufacturing sensors and gauges for the marine industry for over 30 years. As marine enthusiasts start to embrace the new NMEA network, we feel it is necessary to expand our offerings to ensure consumers are able to get their hands on quality products at an affordable price. KUS offers a multitude of NMEA products to fit your needs such as accessories, gauge instrumentation, and liquid level senders, all of which are certified by the National Marine Electronics Association NMEA by passing their testing rigorous testing standards.
More often than not, people are trying to connect and integrate old and new equipment. If you have older equipment that is still functioning and want to connect it to your sparkling new NMEA system, a network signal converter is the most economic choice.
The SeaN series consists of seven single function gauges, and a Integrated Tachometer that also shows real time performance data, such as battery status, engine temperature, oil pressure, and fuel consumption rate.
The instrument integrates major functions such as fuel level, oil pressure, tachometer, speedometer, and oil and water temperature all in one device. Menu Search My Account Compare. Cart You have no items in your shopping cart.
