Controller Area Network. This is a network based serial bus system used for exchanging
information. It is the advanced version of RS485/422 serial buses.
This is a part of the power supply hardware that prevents any damage to the equipment
when the power supply is connected to the wrong polarity.
Rate Of Turn (ROT) signal indicates the course change of a ship in degrees per minute.
This signal can be analog using voltage or current, or can be an NMEA data signal.
Navigation type of instruments displaying the heading/course of a ship.
This is the transmission speed of serial interfaces in characters per second.
The frequency at which complete NMEA sentences are being transmitted in number of
times per second.
Instrument setting for backlight color, language, number of connected apparatus, etc. as
configured as a new instrument by the factory.
Non-volatile type of memory. This type of memory retains its contents even when the
instrument is turned off.
(Embedded) software inside the processors of the AlphaLine instrument.
The minimum distances to equipment that will not cause an unacceptable deviation of
the ship's standard and steering compasses.
