1.4 Accessories
1.4.1 NX2 Autopilot Instrument Control Head
Additional Autopilot Instruments Control Head (PN 20620044) may be added. They
are connected in a "daisy chain" fashion from one to the other, matching colors on
terminals. Control may be transferred from one instrument to another by simply
pressing any pushbuttons (except the OFF push-button) on the instrument where
active control is desired. All other inactive instruments will display the same
information as the active instrument, however in the lower display the text "passive"
will blink once every seven seconds.
1.4.2 NX2 Remote Control Instrument
The Remote Control Instrument (PN 20620048) is an instrument in itself that can
be set in either Autopilot mode to be used as an Autopilot instrument, or Instrument
mode displaying all information on the NX2 Network. The Network Remote Control
Instrument (PN 85006) can be used as a remote control for all instruments
connected to the Network. It is the ultimate NX2 instrument!
1.4.3 NX2 Analog Rudder Angle Indicator Instrument (RAI)
The Analog Rudder Angle Indicator Instrument (PN 20620037) indicates the rudder
angle (50°-- 0° -- 50°). This instrument is connected on the NX2 data bus cable as
per color codes.
1.4.4 NX2 Multi Control Instrument with Server
The NX2 Server is the heart of the NX2 Network to which transducers for speed,
depth, wind, compass and navigators are connected. The Multi Control is a multi-
function instrument that displays a main and a sub-function, grouped into 4 pages
for speed, depth navigation and wind information. The Multi Control instrument and
the Server are the building components of the NX2 Network.
1.4.5 External Alarm Buzzer
An external alarm buzzer (PN 30620023) can be connected to the Server only.
When activated, provides a local alarm at the Control Head in case the Autopilot
falls off course, develops a fault or the helmsman should fall asleep. The buzzer
can be positioned where it may be heard such as in the Captain's cabin, when any
alarm is activated.
1.4.6 NFU Jog Lever
A Non Follow Up (NFU) jog lever (PN 20310002) may be connected through the
Autopilot to directly control the steering Pumpset in any mode except standby
mode. This is useful for docking or remote maneuvering such as required when
picking up crab traps etc. In any automatic pilot mode, the jog steering can be used
as a dodge function and when the jog lever is let go, the boat will revert to the
previous pilot course setting.
