title		CD1.1 multiplexor configuration

body

heading		CD1.1 multiplexor

section		General
heading2	General settings

text		data-mux-cd11 acts as a database for storing CD1.1 subframes. It accepts
		subframes from gdi2cd11 or data-in-cd11 and stores them in day files. These can
		be examined on the web interface (CD1.1 log analyser). data-out-cd11 connects
		to this database for real-time data transmission and can also request subframes
		for backfill.

		A corresponding directory cleaner task must be configured to manage the number
		or size of day files kept by data-mux-cd11.

section		Subframes
heading2	Subframe storage

text		Subframes are written into files (one for each day) in the database directory.
		Ensure that you set up an associated directory-cleaner task to manage flash
		space usage.

field		dbdir
label		Database directory
check		path parent_exists
prompt		Directory in which database files are created. Must be unique.

field		transmit_wait
label		Data frame transmission period
prompt		Number of seconds to wait for more data before transmitting data frames.
check		decimal
help		When the first data frame from a data source with a timestamp T is received, a
		timeout is scheduled. Any further data frames from different sources with the
		timestamp T are coalesced. Once the timeout occurs, all the coalesced subframes
		are sent in a single data frame. This option chooses the length of the timeout.

field		deferred_transmit_wait
label		Backfilled frame transmission period
prompt		Number of seconds to wait for more data before transmitting backfilled frames.
check		nullok decimal
help		If specified, this allows a separate timeout to be used when assembling data
		frames from backfilled data. This could be set to several minutes, to ensure
		subframes from separate backfilling elements are coalesced into as few data
		frames as possible.
