If there is no combined message available a
separate message if available can be used.
If switched ON a free input port must be
selected where the information is coming in.
The information is expected on port "3" and the
correct communication speed must be set.
Some early displays where equiped with a
stepper conversionbox (which is currenlty
obsolete).
In the menu window shown right the step unit
can be switched on or off and if on the correct
transmission speed must be set. This is always
1200 bps.
When it is not possible to get ships speed
information in NMEA format, the pulse input,
normally used for wind speed or remote
brightness control, can be used for speed
input.
If the ships log provides a potential free relay
contact providing 200 pulses per nautical mile,
the relay contacts can be connected to the
pulse input (terminals 28 and 29). In the menu
window on the right option "8" must be selected
for this option.
This input is also used for the remote
brightness control or sensor select.
It can only be used for 1 option!
