General Description GEM
The GEM is a compact, robust panel-mountable
module that enables a user to remotely request
and display engine data. The unit utilises an indus -
try-standard protocol to connect to the engine via
either an SAE J1939 CAN data link.
The GEM incorporates a graphics LCD with five
‘soft’ keys mounted at the bottom of the LCD, pro-
viding a very flexible and intuitive Human-Machine
Interface (HMI).
Associated with the ‘soft’ keys is a graphical menu
structure that uses easily understood icons to indi-
cate the key’s current function. This enables the
operator to select the required engine data and
display it in the following formats:-
•
Analogue gauges
•
Digital data
•
Graphs
•
Multi-data (a combination of the above)
•
Current active alarm messages
Additionally, various diagnostic screens are acces-
sible, allowing detailed investigation of the en-
gine’s data stream.
Getting Started
After power is applied the start-up screen shown
below will be displayed for approximately 7 sec-
onds. If the unit bleeps with a low-pitched tone, the
self-test has failed. Refer to the User Guide sec-
tion for further details.
Once the self-test is complete, the display will
change to show the default engine data screen.
Should the screen need adjusting to improve legi-
bility, press the blue key to select the Contrast and
lighting menu.
If the GEM is connected to an active stream of
engine data, it will now start displaying readings on
the gauges shown on the LCD screen. For further
operating instructions, please refer to the following
section of this document.
