ProductInformation
The HelmView™ Model HV750 display was specifically designed for instrumentation and
control on electronically controlled engines. These engines communicate using SAE J1939
and NEMA 2000 protocols. The HV750 display allows operators to view many different engine
and transmission parameters and service codes. The HV750 can simultaneously display port
and starboard (left and right, respectively) information. Optional upgrades (software and
firmware) are available to expand the usability of the HV750. For more information, review the
following summary about the FW Murphy Forum.

Product Features
Power Up
The HelmView display is frequently installed with power connected to the ignition. When you
turn the ignition on, the HV750 powers up and you can view vital engine conditions via
preconfigured gauge screens.
Main Menu
The main menu can be activated at any time by pressing the Menu key on the display.
Access the following features through the Main menu:
Gauge Display – provides a series of screens that display engine, transmission, and
auxiliary information in a variety of formats.
Engine Diagnostics – displays a list of engine fault codes, descriptions, and
messages.
User Settings – allows you to customize the display options for ambient light and

Gauge Display
The Gauge Display screen consists of several predefined layouts that contain combinations of
analog gauges, straight bar gauges, or digital (text) readouts. These screens display upon
startup.
NOTE: On occasion gauges may ‘grey out’; this is caused when the
HV750 is not reading the CAN message properly from the source address
for which it is configured. This mainly occurs if the message is not being
broadcast on the network, or if the settings within the display are not
configured to read the parameter from the correct source.
A GPS screen is included in the HV750. A GPS device must be connected to the HV750 to
provide time and other readings from which to calculate trip and fuel information.
To scroll through the various gauge screens, press the Previous and Next soft keys. Repeat
this action until all screens have been viewed. The currently displayed screen stays active until
another key is pressed. To review all screens available without accessing the HV750, see the
Gauge Screens section at the end of this document. The following section gives more
information on using the Soft Key Commands.
Soft Key Commands
When a Gauge Display screen is active, pressing the Enter key displays other soft key
commands. Continue to press Enter to toggle through additional soft key commands, and
eventually remove the soft key icons from the screen.

Engine Diagnostics
Choose Engine Diagnostics from the Menu for the HV750 to query the Engine Control Unit(s)
and provide feedback on any activated service codes.
Faults displayed are based on engine or auxiliary sources.

Section 78 00-02-0805
12-09-11 - 11 -
The following is a list of definitions for fields on the Engine Diagnostics screen:
Status – indicates if the fault has been corrected.
Source – identifies the component having the fault - port or starboard engine, or
auxiliary (for example, transmission).
SPN – (Suspect Parameter Number) an SAE identifier fault code
If the SPN is not translated into text by the HV750 display, see the engine
manufacturer's literature for a definition of the SPN number.
FMI – (Failure Mode Indicator) fault code
The FMI is defined by SAE J1939. If not translated into text, see the SAE
standard, or the engine manufacturer's literature.
Count – The number of times the event has been flagged.
Description – The common SPN's and FMI's have a text description stored in the
HV750 display. If there is no text, then define this SPN/FMI by referring to the engine
manufacturer’s literature, or the SAE J1939 standard.
Correction – Troubleshooting guidelines for corrective action to take in resolving the
fault. This field is only used with specific brands and models of engines.
Fault Code Pop-ups
A fault condition triggers a pop-up dialog box on the screen describing the nature of the fault.
The following screens are examples of warning and shutdown fault code pop-ups.

WARNING SHUTDOWN
How to Hide/Show Faults
To hide the fault code pop-up displayed on the screen, press the soft key on the upper right
next to the Hide icon. The pop-up disappears, however the Warning or Stop icon remains on
the screen to indicate there is still a fault. Pressing the Hide soft key does not clear the fault; it
only hides the pop-up message.
When a fault code has been hidden, a Recall icon remains on the right side. When this soft
key is pressed, the fault code displays again. When a fault message is activated, a pop-up
message is displayed until the alarm is acknowledged by pressing the “Hide” key.
