MAX-CSD10: Streaming Commands (Port 1)
The streaming system on the MAX-CSD10 is located at Port 1 in NetLinx D:P:S nomenclature. The
MAX-CSD10 supports the following streaming commands.
For programming purposes, do not use a hyphen when specifying MPEG
functionality. Use MPEG2 and MPEG4 (no dash), do not use MPEG-2 or MPEG-4.
In order for the SET commands (Set Video, Set URL, etc.) to take effect, any active
stream must first be halted using the STOP command. Once these commands are
executed, you can then the PLAY command to restart the stream.
The only exception to this procedure is the SET AUDIO, which while during a stream
can on the fly be toggled between Microphone and Line.
