Faria Serial Bus Installation and Wiring Guide (Evinrude ® Engines)
The system consists of:
• One Gateway box to interface with Evinrude ECM and external senders and sensors.
• One 4” Tachometer with Fuel Monitor
• One 4” Speedometer with Depth Sounder
• Various 2” instruments, including but not limited to
• Voltmeter
• Oil Level gauge
• Engine Temperature gauge
• Fuel Level gauge
• Trim gauge
• Engine Water Pressure gauge
• others as specified.
Installation
Installation of the Faria 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 1 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 2).
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 (*except when a Faria
Serial Bus Pilot or a Faria Speedometer-PerfectPass Cruise instrument is installed, see
note below).
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 2).
The Faria Serial Bus Pilot and the Faria Speedometer-PerfectPass Cruise instruments are
“end of the bus” instruments. Only the provided four (4) pin connector is to be connected to
the “Faria Bus”. See special instructions for use of the six (6) pin connector on these
instruments. *NOTE:

into the calibration mode. The LCD will
show “CAL “.
When the “Up” button is
pushed, the speedometer pointer will
move upscale.
When the “Down” button is pushed, the
speedometer pointer will move down
scale. When the speedometer reads the
same as the reference, release the button.
This process can be repeated as necessary
to ensure correct calibration. Press and
hold the “mode-M” button in to save the
calibration setting and return to the depth
sounder. Release the “mode-M” button
when the depth is displayed.
Tachometer / Fuel Management /
Hourmeter / SystemCheck
The Serial Bus Tachometer/Fuel
Management unit provides six functions,
five of which can be accessed through the
normal running display.
The remaining function, which is “Total
Fuel Consumed”, is provided to allow
monitoring fuel usage over a longer period
of time, such as fuel used for the month or
the season. In order to prevent inadvertent
reset, this function must be accessed using
a special “power on mode”.
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 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-M” button
advances the display through the five
normally available functions.
When in normal display mode, the
instrument lights are turned on and off
with the navigation lights. Intensity is
controlled by the “Up” button. Pressing the
“Up” button will cycle the instrument
lights through three levels of intensity.
Fuel Management
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-M” for more than one
second will allow selecting the units of
measure. Default display will show
“G/H XX.X”. A short press of the “mode-M”
