J1939 Setup
The GSC400 will work with any generator as long as it supports the standard messages
listed in the SAE J1939 specification. Standard messages include oil pressure, engine
temperature, and engine speed. Some engine control modules have proprietary messages
that are intended for specialized devices and are not displayed by the GSC400.
To use J1939 go to the Signal Source submenu for each parameter (see table below) and
select J1939. For example to use J1939 to display Oil Pressure you would go to the
Advanced Menu, go to “Oil Pressure”, go to Signal Source, and then select the J1939
option.

Negative engine temperatures, can be displayed on the GSC400 but any reading below 0
0
C
(32
0
F) is set to 0
0
C for warning and failure level detection purposes (e.g. low engine
temperature).
The GSC400 can display extra parameters for the engines listed in the
Manufacturer
submenu. No warnings or failures can be generated with this data. To enable these
messages, go to the Display Group 1 and Display Group 2 submenus located in the
J1939 menu. If you have a different ECM manufacturer than listed under the
Manufacturer menu, the Display Groups 1 and 2 setting does not apply. Table 11 lists
the data parameters enabled for each group.
