Notes !
1. Simrad products will be identified by the product name
provided the data is available on SimNet. If data is 
provided via an NMEA0183 port on the autopilot 
computer, the display will read NMEA-1 or NMEA-2. 
NMEA2000 products will have a special ID. 
3. In the event the SimNet is not powered on, sources
supplying data to SimNet are not on or malfunctioning, or 
there is no SimNet installed, it is possible to use any 
control unit in the system to select NMEA sources. The 
source select displays are then available on all control 
units.
