3.8 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.

Viewing Engine Parameters from J1939

To use J1939 instead of a local switch or sender:

1. 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.

C for warning and failure level detection purposes.

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.
