DESCRIPTION
The CAN-Communicator (C-COM) Lightbar Message Center (LMC) combines the
advantages of a graphic display with a 28-telltale lightbar. This rugged and
versatile message center can be used exclusively, or as a compliment, to any
existing instrumentation simply by connecting it to an SAE J1939 (CAN) data bus.
The LMC displays data and diagnostics, both active and stored faults from the
individual ECMs, directly from the vehicle data bus.
There are 3 buttons for navigating the screens through an intuitive menu system,
displaying diagnostics, parametric data and popup warnings. Diagnostic
capabilities include both active and stored fault codes from the ECU. Data can be
viewed in a graphical or numeric presentation.
The message center is designed for additional flexibility to the user. The setup
menu screens provide customization of how the data is presented, units to be
switched to English or metric and setting of the display contrast and brightness. A
service alarm can also be set for hours or distance.
The graphics LCD is 340 pixels wide and 90 pixels high, providing clear, legible
graphics. Backlighting can be controlled through the menu or an external dimmer.
The 28 dead-fronted telltales are customizable.
LMC is sealed to IP67 specifications both front and rear of the gauge and operates
from 9 to 32 volts DC. The LMC has 2 CAN J1939 data bus interfaces, J1708 data
bus interface, analog and switched inputs, as well as switched outputs. One of the
CAN interfaces can be used as SAE J1587 to drive NGI gauges or to communicate
on the vehicle data bus
This user guide is intended to help you set up the C-COM LMC, understand
product features and navigate the menu system.

DEF LEVELS
The DEF Gauge, part of the NGI system in the 4-in-1 multi-gauge, operates as stated in
the above table. LED icons will light as indicated, warning messages will be displayed in
the C-COM LMC, and certain audible tones may be activated.
Notes:
1. Final inducement level is activated when the DEF level is 0% and one of the
following conditions is met:
a. Engine is turned off and restarted, or
b. Engine is allowed to idle for one hour, or
c. Fuel tank is refilled without filling DEF
2. Once a low DEF warning is given, the DEF tank must be filled to at least 15% to
deactive the warning.
3. Once a low DEF warning is given, the Check Engine lamp will flash for 30 seconds
at key on.
4. LCD Messages and audible warnings can be dismissed by pressing any of the
three LCD navigation buttons.
