CAN Explorer
Versatile PC-CAN Interface
The CAN bus network is usually associated with vehicle systems or industrial automation but it can also be used in many other situations including home automation. Implementing the network is not a trivial undertaking. This low-cost solution is a CAN board which sits between the CAN bus and a PC. Using the versatile (free) software it can monitor activity on the network and test the functioning of other nodes.
