DL
Recalls a snapshot of all DMX output
channel in T tenths of seconds.
Time is required here. This affects all DMX512 channels.
Syntax:
"'DL<preset number>T<time>'"
If a Direct Ramp is in progress the last command sent will win for
each output.
Variables:
preset number =1-72
time = 0-65535 (time is in tenths of seconds, except where noted).
Examples:
SEND_COMMAND DMX,'DL1T0'
Recalls preset 1 instantly (in zero seconds).
SEND_COMMAND DMX,'DL72T15'
Recalls preset 72 in 1.5 seconds.
Use the groups and group ramp (‘GR’) command to store and recall
scenes with specific channels. Any other snapshot recall or direct
ramp in progress is halted and the ramp to the new level starts from
the current level.
DR
Ramps the DMX output to the L level in
T tenths of seconds. Time is required.
Sends all specified DMX outputs to the
same level.
The list can be single outputs and/or ranges of outputs separated by
commas. If a Snapshot Preset is in progress then the last command
sent will win for each output.
Do not put more 64 characters total in this command.

"'DR<List of DMX Outputs>L<level>T<time>'"
Variables:
List of DMS Output = 1,2,3,5-10 is a list of single DMX channels with
ranges of DMX channels.
