Group Buffer Commands - AMX AXB-DMX512 DMX512 INTERFACE Instruction Manual

Group Buffer Commands

The group buffer is modified by changing group commands.
There is a maximum of 96 groups in software version 1.10.
Adding outputs to a group while the group is still connected to an Axcess level DMX
output can cause the value of outputs, which are already a member of the group, to
change.
The following table lists the Group Buffer Send_Commands.
Group Buffer Commands
Command
GA
Adds one or more DMX outputs to a
group.
AXB-DMX512 DMX512 Interface
Description
The list can be single outputs and/or ranges of outputs separated by
commas. A DMX output can only belong to one group at a time.
Any of these outputs, that are currently members of another group,
are automatically removed from that group. Adding an output to the
group does not change the current DMX value for that output in the
Group Buffer. This means that its possible to have different DMX
values for the channels in this group at the time the channels are
added, but this command is intended for the control of a group of
outputs that will have the same value at all times.
Syntax:
"'GA<group>D<list of DMX output>'"
Variables:
group = 1-96
list of DMX output = 1,2,3,5 - 10
If this group is direct ramped ('GR') to a level, then the offset between
channels will be lost.
If this group is ramped up ('GU') or down ('GD'), then the channels
maintain their relative values until these channels hit zero or full. This
effectively 'clips' the channels and eliminates the offsets between the
values.
Example:
SEND_COMMAND DMX,'GA1D1,3,5-7'
Adds DMX Output Channels 1, 3, 5, 6, 7 to Group 1.
SEND_COMMAND DMX,'GA1D-5'
Adds DMX outputs 1 through 5 to Group 1.
SEND_COMMAND DMX,'GA96D6,10'
Adds DMX Outputs 6 and 10 to Group 96.
