Avoid placing the Device’s wire near voltage regulators, an alternator or other sources
of electro-magnetic noise. If the wire is too long, you may cut it. If the wire is too short,
you can enlarge it, but note that a longer wire can also catch more noise. If you have a
choice between enlarging of NMEA 2000 cable and Device’s wire, it is better to enlarge
the NMEA 2000 cable, because it is designed to work in a harsh environment and is
less susceptible to electromagnetic interference.
The ignition system sends from one impulse per two revolutions (most 2-stroke twin-
cylinder outboard motors) to 8 impulses per revolution to a spark plug, depending on
the engine type and the ignition system type. The factory setting of the Device is one
impulse per revolution (classic 2-stroke engines, 4-stroke engines with CDI).
