3.3 Carry out configuration
ETS 4000 SAE J1939 V03
Before the settings can be changed the ETS must be set to its editing mode. The changed settings must then be stored and a restart needs to be carried out. Please see chapter "commands" below.
To read and write the settings, the master sends a message with the parameter group number 61184 to the ETS's address. ETS responds by the same parameter group number and sends an acknowledge code.
In case of reading requests the requested data are sent with the code.
3.4 Message data structure
The content of the messages is listed in the following table:
Byte Content
0
1
2
Setting index r/w, 0=read, 1=write
Sub index of the configuration (0 if no sub index is used)
3 Acknowledge, see remarks
4-7 Data LittleEndian
For entries in which a sub index is used, i.e. 59 (status channel) a sub index has to be set in order to inquire the channel.
