SimNet Simrad Intelligent Marine Network

Standard Interfacing NMEA183 - single transmitter multiple receivers Point to point connection One receiver can only listen to one transmitter Complicated installation Complicated setup

SimNet Integration Objectives: Easy installation Automatic system setup Unlimited data sharing A solution for the future

SimNet Network

What is SimNet ? Simrad intelligent marine Network A complete intelligent network system for easy installation and integration of marine electronics Easy installation Easy setup - Plug and Play approach Reliable data transfer NMEA2000 compatible. SimNet

SimNet Specifications Based on CAN bus, Controller Area Network, from the automotive industry and NMEA2000 Up to 50 products in one system (Up to 250 network adresses) Signal rate: 250 Kbit/sec. 50 times faster than NMEA183 Maximum total SimNet cable length: 120 (+30) meter Maximum current: 5 Amps Guaranteed transfer of priority data Automatic source selection Automatic multi source management Ready made cable and plug system

Cable and Plug System Highly innovative cable and plug system ! Thin cables with small 9 mm plugs, easy to run Watertight, IP66 Ready made cables Accessories readily available from shop stands 3 year active use in the field

Competing plug and cable systems NavNet Must use a Hub – star coupled Complicated to configure Not water proof Not NMEA2000 compatible SeaTalk2 Large and bulky plugs Not NMEA2000 compatible No support for multiple sources NMEA2000 Expensive plug and cable system Two connector sizes approved Drop cable only (No Daisy chaining) The winner is SimNet Control

SimNet Cables Network Load 1NL= 50mA Data pair: AWG 24 (0.24 mm2) 2 x 2 twisted pair Net-H Net-L Data Net-S Net-C Power Data pair: AWG 24 (0.24 mm2) Power pair: AWG 20 (0.5 mm2) Resistance = 2*0.03ohm/m

SimNet Integration Power cable w/termination Ready made cable w/plugs Tee joiner Active Tee, AT10, AT15, AT44

Typical power boat installation

Sailboat installation with long MHU cable

All data available to all products ! AT10 NMEA0183 Converter All data available to all products !

Product C will not get data from B AT10 NMEA0183 Converter Product C will not get data from B

Network Considerations Remember ! Proper network installation and termination is important ! 12 or 15VDC 24V, 110V 240V

Good SimNet Installation Run SimNet cable separated from power cables (110/240V or 12/24V) Pay special attention to cables supplying high currents. (electrical motors, radar's, thrusters….) It is recommended to secure long SimNet cables max. 50 cm (20”) from the SimNet plug. Max. Cable length 120 m (400’) including drop cables. Single drop cable max. 6 meter (20’) - total drop cable length max. 60 meters (200’)
