Engine Source; Display Can Add; Alarm Filter; Spn Version - Generac Power Systems MAGNUM MTP4SZ Owner's Manual

Operation

Engine Source

Selects which source the display listens to for gauge data.
Every device on a J1939 network has a unique address
(in the range 0-254) to which the display can choose to
listen. The display listens to a single data source; usually
the ECU at address 0.
NOTE: Incorrectly configuring the Engine Source
address will result in no data available for display.

Display CAN Add

The default display has the unique address of 40, the
recommended address for single engine setups.
NOTE: Incorrectly configuring the Display CAN Address
can result in data collisions on the CANbus.

Alarm Filter

This setting specifies whether the display will display
alarms from all sources (Glb or global) or only the source
address specified in the "Engine Source" setting (Src or
source).

SPN Version

Selects the default SPN (Suspect Parameter Number)
conversion method version automatically.
NOTE: Selecting the wrong version will cause alarm
data to be displayed incorrectly.

Speed Source

There are three sources of speed data the display can
decode. The settings for this parameter are Auto, NMEA,
Wheel, Nav, and Off. Auto prioritizes the sources (highest
to lowest); NMEA, Wheel (PGN 65265), Nav (PGN 65272).
The selection can be forced to one of the available sources
by selecting it explicitly. Selecting Off stops the display
listening to any source of speed data.

PIN Settings

By default, PIN (Personal Identification Number) security
is disabled. The user is prompted to enter a PIN every time
