Operation Manual
5.6 Configuration
The complete configuration of the T-Series CANbus sensor is done through the CANbus interface.
5.6.1 Layer Setting Service (LSS)
Every CAN device must have an unique node identifier in the CAN network.
The node-ID and the baud rate can be programmed by using the LSS protocol DS 305 published by the CiA.
To program the node-ID and/or the baud rate the T-Series CAN sensor has to be changed to the LSS configuration state.
