Navy Gateway (GW0016)
System Manual

The system consists of:

• One Gateway box to interface
with engine and external
senders and sensors.

• One 4” Tachometer with Fuel
Monitor

• Various 2” instruments,
including but not limited to

• Voltmeter

• Oil Pressure gauge

• Fuel gauge

• Engine Temperature gauge

• Transmission Temperature

Quick operation:

1. To turn on the system: Turn the ignition
key to “ON” position.

2. To turn off the system: Turn the ignition
key to “OFF” position.

3. To turn on instrument lighting: Turn
on the light switch on the vehicle instrument
panel.

4. To turn off instrument lighting:
Turn off the light switch on the vehicle
instrument panel.

5. To change the lighting intensity,

(requires the light switch be turned on):

intensity is reached no further changes can
be made by pressing the “DOWN” button.

6. To disable the audible alarm in normal

mode: PUSH and HOLD both the
“UP” and the “DOWN” buttons on the

tachometer until the beeping stops.

7. To change the LCD display (engine
hour meter, system voltage):

a. Pressing the “Mode” button on the
tachometer will select the next LCD
display.

b. Press the “Mode” button repeatedly
until desired function is displayed. The
gateway will switch to a screen displaying
the function data within 2 seconds after the
button is pressed.

a. Turn on the light switch as described in
item 3 above.

b. Pushing the “UP” button on the tachometer
will increase the intensity of the instrument
lighting. When maximum intensity is
reached no further changes can be effected
by pushing the “UP” button.

c. Pushing the “DOWN” button on the

tachometer will decrease the intensity of
the instrument lighting. When minimum

8. To reset Trip Fuel Consumed:
a. Use quick operation 7 above to show
“CLR TRP” on the LCD. Hold the “M”
button for more than one second while the
LCD displays “CLR TRP” to clear the trip

amount.

System Description

♦ There are three push buttons (Mode,
UP, and DOWN) for selecting different
message screens, changing the instrument
lighting intensity, disabling audible alarm,
etc.

When the system is turned on, the pointer
on each of the instruments will be driven
to its most counter clockwise position, all
positions in warning arrays will light, and
all LCD segments on the 5” tachometer
are activated for 2 seconds. These actions
provide a quick check of system operation.
After this “boot-up” display, all instruments,
warning light arrays and LCD screen will
change to normal operating mode.

Installation

See Appendix 1: “Installation and Wiring”
at the end of this manual.

System Operation:

After installation in accordance with the
instructions and recommendations in the
Installation section (see Appendix 1), the
system is functional.

Tachometer / Fuel Management

The Serial Bus Tachometer / Fuel Monitor
instrument provides both the functions of a
tachometer and a fuel and engine monitoring
system.

♦ Audible and visual alarms. The LCD
will display Warning messages while an
audible “beep” occurs.
♦ The Gateway is environmentally
sealed, and is water resistant per SAE
J1960 paragraphs 4.6.2, 4.7.1.2 and

4.8.1.2.
♦ Faria® serial bus gauges/light arrays
can be connected up to 120 feet (40
meters) from the gateway box.

Turning the Gateway System
ON/OFF

When the “ignition” switch is turned to the
“on” position, the system is turned on. When
“ignition” switch is turned to the “off”
position, the system will turn off.

The analog tachometer is a stepper motor
instrument which looks like a standard
analog device but which is actually a digital
instrument. On small pointer movements you
may occasionally see the pointer moving in
the one-third degree “steps” that represent
the accuracy of the instrument.

The LCD shows messages, like engine
hours, system voltage, and engine alarm
conditions.

In order to minimize “false” alarms, the
“low voltage” alarm only functions when
the engine is known to be running based on
the presence of tachometer data.

Several alarm conditions may also be
displayed in the LCD display when needed:

1 Low fuel
2 Low oil pressure
3 Low voltage

Alarm messages will be displayed on the
tachometer LCD display. Messages will also
include a flashing red light. All messages
will be displayed until either the problem is
corrected or the operator manually cancels
the warning message.

Canceling system alarms

To manually cancel system warning
messages, simultaneously press both
the “Up” and “Down” buttons on the
tachometer.

This will disable the warning message
temporarily. If the problem is not corrected
in 1 minute (5 minutes for low fuel), the
warning will be displayed again. The
operator can cancel as often as desired.

The LCD screen displays the data for the
remainder of the functions. If there are
no alarm conditions, “Instantaneous Fuel
Consumption” is displayed on start-up. A
short press of the “Mode” button advances
the display through the five normally
available functions.

There are four functions displayed by the
Fuel Management system in normal mode.

Instantaneous Fuel Consumption

Displays the actual amount of fuel being
consumed per hour under the current
operating conditions. Default display will
show “G/H XX.X.”

Pressing the “Mode” button for more than
one second will allow selecting the units of
measure.

Default display will show “G/H XX.X.”

Engine Hour meter

Displays the number of hours that the engine
has been operated. The display will show
“XXXX.XHr”.

There are no adjustments for this function.

Total Fuel Consumed

“Total Fuel Consumed” is provided to
allow monitoring of fuel usage over a
longer period of time, like a month or the
season. In order to prevent accidental reset,
this function must be accessed only using a
special “power on mode.”

A short press of the “Mode” button advances
the display through the options.

Options are:
a) US gallons
