Description of functions

 

CAN identifier for transmis-
sion of the data to the CAN 
bus 

All CAN identifiers are possible  SendID 

(under [CANlink]) 

CAN identifier for receiving 
data from CAN bus 

All CAN identifiers are possible  ReceiveID 

(under [CANlink]) 

Table 4-1 

 
In the CANlink mode, the device transmits the data that arrive on the serial port 
to the CAN bus under a configurable identifier. In the same way, data that are 

received via CAN by means of another configurable identifier are passed on to the 
serial port.
