NMEA 2000 and SimNet devices
NMEA 2000 devices can be connected to the CAN bus providing they are NMEA 2000
certified, meet the CE, FCC regulations and do not exceed the load specification.
NMEA 2000 devices and SimNet devices with Micro-C connectors connects directly to the
CAN bus backbone using drop cables and Micro-C T-joiners.
¼ Note: It is recommended to use a gateway when connecting non-Simrad units to the CAN
bus backbone.
Devices with SimNet connectors only must be connected using a SimNet to Micro-C adapter
cable.
IEC61162-1/2 (NMEA 0183) devices
Connects to: AC70 (in AC70 or AC85 Computer) and SI80 board (in SI80, AC80A, AC80S or
AC85 computer).
The AC70 board have 1 NMEA terminal, while the SI80 board includes 4 NMEA terminals.

The green LED at each NMEA terminal is living when serial data is received.
The board uses the serial RS422 (IEC 61162-1/2) standard and can be configured in the
software for different baud rates, up to 38.400 baud. Sentences output by the autopilot
computer can be individually turned on or off.
