Multi-line messages
The DLM4000 supports interface messages marked with a *.
Note
Difference between SDC and DCL
In multi-line messages, SDC messages are those that require talker or listener designation and DCL
messages are those that do not require the designation. Therefore, the SDC command affects a specific
device while the DCL command affects all devices on the bus.
