NorthStar Navigation 435, 438 Flush Mounting, Bracket Mounting, Removing the display unit

Page 25

•Bracket mounting requires a panel for mounting the bracket. Ensure that the panel is not likely to deform and is not subject to excessive vibration. The bracket can be tilted and rotated so the Explorer 435 and Explorer 438 can be removed after each use.

Select a position where the display unit will be:

•At least 4" (100 mm) away from the compass.

•At least 12" (300 mm) away from any radio transmitter.

•At least 4 ft (1.2 m) away from any antenna.

•Easy to read by the helmsman and crew while underway.

•Protected from physical damage during rough sea passages.

•Easy to access the 12 V DC power source.

•Convenient to route the transducer cables.

Flush Mounting

1.Cut a hole in the bulkhead for the display unit using the flush mount template.

2.Drill four holes for the mounting studs using the flush mount template.

3.Screw the four studs into the brass inserts in the back of the display unit.

4.Sit the display unit in place and fit the washers and nuts to the studs.

Bracket Mounting

1.Fix the mounting bracket onto the boat using the three stainless steel screws. Do not overtighten the screws, as the bracket may not rotate.

2.Push the display unit onto the mounting bracket and tighten it firmly using the knob on the mounting bracket.

3.Attach the cables.

Removing the display unit

The display unit can be removed after each use for protection against the environment or security reasons.

When removing the display unit, ensure that the plugs left in the boat are not exposed to the elements. Push the attached dust covers over the exposed ends of the plugs. Keep the display unit in a dry clean place such as the optional Northstar carry bag.

6-4 Wiring Options

The power/data cable contains 5 wires:

Wire

Function

Black

Ground (power negative)

White*

NMEA out

Red

Positive power in, 12 V DC

Yellow

Auto power in (connect to red wire.

 

Positive power in, to enable Auto power).

Green* External beeper or light out, switched to ground, 30 V DC 200 mA maximum.

Note: The cable shield is connected to Pin 1 (black wire) and does not need to be grounded. * Denotes Explorer 438 only.

CAUTION

1 Amp fuses must be positioned where shown in the wiring diagrams.

Six wiring options are described in this section:

•Basic wiring. This does not start the fishfinder automatically when the boat ignition is switched on and it disables the engine hours counter.

•Auto power wiring. This must be used for the engine hours and fuel computer options.

•Secondary Alarm wiring

•NMEA wiring

•Single engine fuel wiring

•Twin engine fuel wiring

Note: If a wire color is not specifically mentioned, it is not used in that wiring option.

Section 6-5 Systems of several instruments, describes NMEA and NavBus.

Basic wiring

This requires the Explorer 435 and Explorer 438 to be powered on manually with the key.

Black wire: Connect this to the negative battery terminal.

Red wire: Connect this to the positive battery terminal after the main switch. Fit a 1 Amp fuse as shown.

Yellow wire: Connect this to the black wire. This disables the engine hours counter.

Power on the fishfinder manually whenever the main switch is on.
