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.
Page 3
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
Page 4
b) Imperial gallons. Display will show
c) Liters. Display will show
Leaving the display in one of the items
above while the “Mode” button is pressed
and held for more than one second will save
the selected units.
Trip Fuel Consumed
Displays fuel consumed since last reset. This
function can be reset to zero before a trip to
show fuel consumed during the trip. Display
shows “TRPXXX.X.”
Pressing the “Mode” button for more
than one second while the display shows
“CLR TRP” will clear the trip amount and
set the menu back to the Trip Fuel Consumed
function.
A quick press of the “Mode” button will
skip this feature.
b) Adjust Trip Fuel Consumed, (fuel flow
calibration). Display will show “ADJ
TRP.”
Pressing the “Mode” button for more than
one second will cause the display to go into
the Trip Fuel Consumed adjustment menu.
Pressing the “Mode” for more than one
second will access the options that are
available for this function.
A short press of the “Mode” button advances
the display through the options. Display will
show “TRPXXX.X.”
Options are:
a) Clear Trip Fuel Consumed. Display will
show “CLR TRP.”
Page 5
The display will show “ADJXXX.X.”
Pressing and holding the “Up” button will
increase the amount and pressing and
holding the “Down” button will decrease
the amount.
Holding the “Mode” button for more than
one second while the display is showing
“ADJXXX.X” will set the amount in
the display “XXX.X” into the Trip Fuel
Consumed and return to the Trip Fuel
Consumed function.
The difference between the original and the
new amount of fuel will be used to change
the calibration of the instant and accumulated
fuel data.
This feature allows the fuel flow system to be
calibrated by accurately filling the fuel tank
at the beginning and end of a trip. When the
tank is refilled at the end of the trip, record
the exact amount of fuel placed in the tank.
Using the above method, adjust the amount
of fuel shown in the “ADJ TRP” to match the
amount of fuel recorded. Save the corrected
amount as described above. The “Trip Fuel
Consumed” in the previous menu can then
be cleared for reuse or left to continue to
accumulate fuel usage.
Fuel Remaining
Displays the fuel remaining based on a
manually entered amount of fuel minus the
amount of “Trip Fuel Consumed.”
Display shows “REMXXX.X.” This reading
is independent of the fuel “gauge” reading.
In normal use, the amount of fuel in the fuel
tank is adjusted manually when the fuel
tank is filled so that this display shows the
total amount of fuel in the tank. The “Trip
Fuel Consumed” is then reset to zero. As
fuel is used (displayed in the “Trip Fuel
Consumed” display) this display will show
the decreasing amount of fuel remaining.
Pressing the “Mode” for more than one second
will access the option available for this function.
a) Add to or remove gallons from the Fuel
Remaining. Display shows “R+-XXX.X.”
Holding the “Up” button will increase the
amount and holding the “Down” button will
decrease the amount.
Holding the “Mode” button for more than
one second will set the remaining fuel to the
value shown in the display and return the
menu to the Fuel Remaining alarm Setting
function.
This feature allows the operator to accurately
set the amount of fuel in the fuel tank when
adding fuel. The accuracy of this manually
entered value directly affects the Fuel
Remaining and Fuel Remaining Alarm
functions, and should be done carefully.
Fuel Remaining Alarm Setting
Displays the setting for the “Low Fuel”
alarm. The display shows “ALRXXX.X.”

Faria® Serial Bus Installation and Wiring Guide
The system consists of:
• One Gateway box to interface with the engine and external senders and sensors.
• One 4” Tachometer with Fuel Monitor
• Various 2” instruments, including but not limited to
• Voltmeter
• Oil Pressure gauge
• Engine Temperature gauge
• Fuel Level gauge
• Transmission Temperature
Installation
Installation of the Fari® Serial Bus system is accomplished as follows:
Gateway Box
The Gateway™ box is the central unit of the system. As all of the senders and other
information source peripherals connect to the Gateway™, the Gateway™ box should be
mounted in a protected area in the best location to provide the maximum cabling benefit.
The Gateway™ box power cable must be installed to allow connection to “battery positive”
(always on), “battery negative” (ground), and a source of “switched power” which turns on
with the engine ignition switch (see Figure 2 and Table 1).
The “Faria® Bus” cable must be routed from the Gateway™ box to the instrument panel area
to connect the instruments to the data bus and instrument power (see Figure 3).
The remainder of the connections to the Gateway™ box are described below.
Instruments
The instruments are mounted using the provided back-clamps and mounting hardware.
Each instrument comes with a bus connection cable (12”). The main “Faria® Bus” cable
from the Gateway™ box is connected to the most convenient instrument using either of the
two four (4) pin connectors provided on the instrument case.
Each additional instrument is connected to the previous instrument using one of the 12” bus
connection cables. The cable may be connected to either of the two connectors provided on
the instrument case (see Figure 3).
