Connection Environments
- The CAN bus accommodates connections of a number of units to it.
- There are no limitations on the number of units that can be connected to the CAN bus, however, if the bus length needs to be longer or the bit rate needs to be higher, the number of units needs to be smaller. On the other hand, if the bus length is relatively short or a relatively slower bit rate can be accepted, a greater number of units can be connected.
- As signals are distinguished with the voltage difference between the two bus lines (CAN_High and CAN_Low), the main lines and branch lines must be properly connected.
