The adapters are protected against transmitting against each other, but for all real messages (> about 32 bytes) each adapter only has one receive buffer. If you transmit a second packet to another node before it has read the first out, or worse if two different nodes transmit a packet each to a third node in a small interval, all hell breaks loose. All the adapters forget all the messages (including the one already in the buffer) and you have to issue reset commands to them all.
