Faria ® MG2000 J1939
Tachometer Manual
The Faria MG2000 Tachometer
combines the features of an ECU serial
bus gateway and several instruments
into one unit:
• The tachometer is analog in
appearance but is driven by a stepper
motor for digital accuracy.
• The high resolution LCD screen
displays information for many other
functions and the various “screens”
can be configured as the user
wishes. As received, the screens
are configured as shown in Fig. 1.
The MG2000 tachometer receives digital
engine data from the Engine Control
Unit (ECU), and Transmission Control
Unit (Commercial Application) via the
SAE J1939 bus and can receive GPS
information via a NMEA 0183 connection
to a suitable GPS unit.
GPS information is displayed in the
MG2000 speedometer. Active Engine
and
Transmission (Commercial
Application) fault codes are supported in
this version of the J1939 tachometer and
are viewed in the alarm screen.
Analog inputs are provided for two
non-engine sensors, fuel level and trim
position. An optional direct pressure
port allows monitoring of engine water
pressure if installed.
The MG2000 provides a Faria Bus
output to allow use of various 5, 4, and 2-
inch instruments with the MG2000. The
application will determine the instruments
supported.
The Faria MG2000 tachometer will turn
on when the ignition key is turned on
and will turn off when the ignition key is
turned off. The unit will power up first
showing the Self Test screen and then
the default screen set at the factory or
the screen selected by the user in the
Default Screen Edit selection prior to
shut off.
