Chapter 2: System Integration
Introduction
This chapter provides an overview of system integration, you may find that your 
system does not use all the protocols or contain all the instrumentation that is 
described in it. However it is hoped that the information supplied will help in your 
understanding of how systems can be integrated and used successfully.
2.1 What is System Integration?
System integration enables various instruments and displays to communicate with 
each other and use the collected data to increase the functionality of the system. 
This data exchange is only possible if the data gathering is accurate, and transfer 
between instruments is fast and accurate. 
Fast and accurate data transfer is achieved by using a combination of the following 
data protocols:
• SeaTalk.
• SeaTalk

.
• National Marine Electronics Association (NMEA)0183.
• NMEA 2000.
• SeaTalk High Speed.
When two or more E-Series Displays are networked, all shared data can be viewed on 
any display.
What is SeaTalk?
SeaTalk
The SeaTalk protocol enables compatible instruments to be connected to a simple 
network by way of a single cable carrying power (12 volts, 150 mA) and data in/out, 
without a central processor. 
Additional instruments and functions can be added to a SeaTalk system, simply by 
plugging them into the network. SeaTalk equipment can also communicate with other 
non-SeaTalk equipment via the NMEA 0183 standard, provided a suitable interface is 
used.
