Part 1 - Introduction
HB-0846-03
1-6
The NMEA FFD contains an NMEA interface which enables the
HS 2000 to connect to other sensor devices such as position
fixers, autopilots, track plotters and radars provided by other
manufacturers. For example, information from the GPSplus can be
transferred from the bridge to a steering position above decks. The
HS 2000 can also provide information to other instruments; speed
and heading for example can be output to radars, chart plotters
and other navigational devices provided the instruments are
NMEA compatible.
Two further display types can be added to the system, these are:
Standard FFD
20/20 Display
1.4.2 Standard Full Function Display (FFD)
The Standard FFD is identical in operation and appearance to the
NMEA FFD. The only difference is that the Standard FFD does not
have an NMEA interface installed.
1.4.3 20/20 Display
The HS 2000 20/20 Display is a lightweight, large digit, liquid
crystal display and can be configured from any FFD or a remote
button to display system information.
The 20/20's operation is fully explained in Part 5 - Options.
1.5 CALIBRATION
Before using the HS 2000 for navigational purposes, it is important
that the system is calibrated for your installation. The HS 2000
calibration process has been simplified as far as possible, so that
all you require for accurate instrument data is a little background
knowledge and the application of a few simple techniques. These
are fully explained in Part 3 - Calibration.
1.6 DAMPING
A useful feature is that the damping on most functions is user
adjustable. This allows the response of the function to be slowed if
it is too jumpy in rough weather, and similarly the response can be
quickened when in flat water. The damping operates by averaging
the numbers over a time period - the more you increase this time
period the smoother the data readings will be, but the longer it will
take to view the effect of any change; similarly the lower the time
period the larger the jumps in numbers but the response to any
change will be quicker. Remember, high damping for rough
weather, low damping for calm weather.
