11.5.4 Interface connection
The 44 and 54 series feature three possibilities for interconnection and data
sharing:
1. SimNet, which is recommended for control and data sharing
between Simrad SimNet products.
2. NMEA2000, SimNet products will interface and share data with
NMEA2000 based products.
3. NMEA0183, which has been the common standard for marine
electronics. Interface connections are made to the receptacle marked
“NMEA1” or “NMEA2” on the rear of the cabinet – turn the plug’s
coupling ring clockwise until it stops.
The unit must be turned off while connecting/disconnecting the
interface cable.
SimNet is a high-speed control and data network designed to integrate SimNet
products into a complete system. Ready-made cables with small plugs makes
it easy to run cables. Only 10 mm (3/8”) holes are required through panels and
bulkheads. The SimNet accessory program contains the necessary items to
make a successful installation, see section 11.10 Specifications.
Plug and Play - once all products are connected and power is switched on, the
entire network system will be set up automatically and will ensure optimum
performance.
SimNet connection is made via AT44, which is a special SimNet to NMEA
converter with a plug for the NMEA2 receptacle and two sockets for SimNet.
