Receive-only Mode
The receive only mode is designed for a special test procedure to check the bus
connections. Figure 5 shows a network consisting of 5 nodes. If the connection between
node 1 and node 3 shall be tested, the nodes 2,4 and 5 are switched into receive only
mode. Node 1 and node 3 are in normal mode. If node 1 sends a message, node 3 is the
only node which can acknowledge the message, the other nodes can only listen but
cannot send an acknowledge bit. If node 1 receives the acknowledge bit from node 3,
the connection is OK.
