CAN Bus Data Packaging
This section outlines the CAN Protocol used to communicate with the ELC device(s). If the
device is connected to an Emtron ECU, the CAN Bus packet is automatically decoded when
CAN ELC Dataset is selected and no additional setup is required. For more information refer
to Section
7.
0.
This section provides more detailed information on the CAN ID data structure and requires
an understanding of both CAN protocols and data packaging.
Baud Rate
The device will Auto-scan the CAN bus until a successful baud rate has been detected. Once
detected this rate will be stored by the device and used at the next power up.
The device will scan 3 different Baud rates at 500ms intervals moving from 1Mbaud ->
500kBaud -> 250k Baud -> 1Mbaud and so on.
