This document describes the installation method of SimNet Intelligent Marine Network, including network description, network architecture, technical specifications and other content.
This manual serves as a reference guide for correctly installing the Simrad Intelligent Marine Network (SimNet). It explains how data is exchanged between products, how to set up automatic interfaces, and how to select data sources. The document details the integration of SimNet with NMEA2000 products and provides instructions for both daisy chaining and drop cable connections.
| Maximum number of products connected in a network | 50 |
|---|---|
| Maximum total cable length | 120 meter (400') |
| Bit rate on the bus | 250 Kbit / second |
| Maximum DC current through a single SimNet plug / connector joint | 5A |
| Maximum number of network loads | 80 NL |
| SimNet power supply voltage | 12 V Battery or 15 V Power supply |
| Maximum drop cable length | 6 meter (20') |
| Maximum total length of all drop cables | 60 meter (200') |
| Environment: Dust/water rating | IP66 (IP67) |
| Environment: Temperature | 70 oC (158oF) |
The data transfer capability of SimNet is 50 times higher than the NMEA0183 standard.
Yes, SimNet's flexibility enables the interface of NMEA2000 certified SimNet products into a NMEA2000 data network.
SimNet products are designed for daisy chaining or for connection via drop cable and a SimNet T-joiner.
The System Size Factor is calculated by multiplying the total network load (NLtot) by the total cable length (Ltot).
