FIG. 4 AXB-DMX512 (rear view)
Preparing/connecting captive wires
1. Strip 0.25 inch of wire insulation off all wires.
2. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and
connector types described in this section. Do not tighten the screws excessively; doing so may strip
the threads and damage the connector.
Wiring guidelines
The interface requires a 12 VDC power to operate properly. The Central Controller supplies power via
the AxLink cable or external 12 VDC power supply. The maximum wiring distance between the Central
Controller and interface is determined by power consumption, supplied voltage, and the wire gauge used
for the cable. The table below lists wire sizes and maximum lengths allowable between the AXBDMX512 and Central Controller. The maximum wiring lengths for using AxLink power are based on a
minimum of 13.5 volts available at the Central Controller’s power supply.

Replacing the Lithium Battery
A lithium battery (FIG. 8) with a life of approximately 5 years, protects stored presets if a power loss
occurs. The battery is not used when DC power is supplied to the AXB-DMX512. Write down the
replacement date on a sticker or label by adding 5 years to the date of installation, and then attach it to
the bottom of the AXB-DMX512.

socket
FIG. 8 Lithium battery and socket
All control commands in AXB-DMX512 memory are lost when the lithium battery is
replaced
Contact your AMX dealer before you replace the lithium battery and verify that they have a current copy
of the Axcess program for your AXB-DMX512. This will avoid any inadvertent loss of data or a service
outage.
You will need a flat-blade tool (non-conducting) that can be slipped under the lithium battery to pry it up
and out of the socket.
Static electricity can damage electronic circuitry. Before removing the lithium battery
from the enclosure, discharge any accumulated static electricity from your body by
touching a grounded metal object.
1. Discharge the static electricity from your body.
2. Unplug all cables from the AXB-DMX512.
3. Remove the AC-RK and AXB-DMX512 from the mounting rack. Otherwise, go to step 4.
4. Remove the five pan-head screws on the top of the AXB-DMX512 enclosure.
5. Pull the two enclosure halves apart and set the bottom portion of the enclosure on a flat surface.
6. Locate the battery on the circuit card.
7. Carefully pry the battery out of its socket and insert the new battery. Write down the next
replacement date on a sticker or label by adding 5 years to the replacement date, and then attach it to
the bottom of the AXB-DMX512.
8. Plug all cables back into the AXB-DMX512.
9. Place the top portion of the enclosure back onto the bottom portion. Then, refasten the five pan-head
screws.
10. Reconnect the cables removed for battery replacement.

AXB-DMX512 DMX512 Interface
Configuration and Installation
There is a danger of explosion if you replace the battery incorrectly. Replace the
battery with the same or equivalent type recommended by the manufacturer. Dispose
of used battery according to the manufacturer's instructions. Never recharge,
disassemble, or heat the battery above 212 °F (100 °C). Never solder directly to the
battery or expose the contents of the battery to water.

Programming
Programming
The AXB-DMX512 is controlled with Axcess Send_Commands. Use the programming information in
this section along with the Axcess Programming Language Instruction Manual to program the AXBDMX512.
All Send Commands are limited to 64 characters.
Buffers
The AXB-DMX512 uses a “highest value takes precedence” to determine which DMX value is actually
output (see FIG. 1). There are three output buffers: patch, group, and direct control. Each buffer
represents all 512 DMX outputs. The highest value in any buffer is the value transmitted from the output
port. The actual DMX output refers to the value being transmitted.
DMX Input
Patch Buffer
Group Buffer
Actual DMX Output
The highest value of any buffer
Direct Control Buffer
FIG. 1 DMX Flow Chart
The levels in the patch buffer are modified by DMX Input. The patch buffer commands determine which,
if any, DMX inputs modify the level of the patch buffer. A patch disconnect automatically clears the
value in the patch buffer to zero. If there is no DMX Input for 5 seconds, all values in DMX Input buffer
are set to zero. Any outputs tied those DMX Inputs will then be zero.
The group buffer is modified by changing group commands. Groups can ramp over time. Groups can be
tied to Axcess levels or DMX Inputs. The groups can be absolute or proportional. For groups that are
absolute, the value of all outputs are the same as the group level. Proportional group outputs depend on a
specified value or the Actual DMX output at the time the output is added to the group. That value sets the
maximum value the outputs can reach when controlled by group 55.
The direct control buffer is modified by individual output ramps or by preset recalls. Presets are also
called snapshots or scenes.

Programming
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
Description
GA
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.
Adds one or more DMX outputs to a
group.
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.

Programming
Group Buffer Commands (Cont.)
Command
Description
GC
A group can only be tied to one or the other not both. The list can be
single groups and/or ranges of groups separated by commas.
Connects one or more groups to an
Axcess level or to a DMX input.
Syntax:
"'GC<list of groups><A or D><Axcess level or DMX
input>'"
Variables:
Axcess level = 1-8
DMX input = 1-512
If a single group is connected to an unconnected Axcess level, then
the Axcess level value will change to the group value. Otherwise, the
group value will change to the Axcess level.
There are 4 possible scenarios with this command:
Connecting a single group to an Axcess level: The Axcess level
changes immediately to reflect the current level of the group for normal groups. The group level immediately changes to reflect the
Axcess level for proportional groups and fixed groups. The group can
now be ramped up and down via the Axcess level ramp commands
(‘AU’, ‘AD’, and ‘AS’). It is no longer possible to use the group ramp
up (‘GU’) or down (‘GD’) commands, but the direct ramp command
(‘GR’) and Axcess channels still work, and also affects the Axcess
level. If the group is disconnected using the ‘GX’ command, the group
ramp up and down will work again.
Example:
SEND_COMMAND DMX,'GC1A2'
Connects Group 1 to Axcess level 2.
Connecting multiple groups to an Axcess level: The group levels
change immediately to reflect the current Axcess level. The group can
now be ramped up and down via the Axcess level. It is no longer possible to use the group ramp up (‘GU’) or down (‘GD’) commands. The
direct ramp command (‘GR’) and Axcess channels still work but now
controls all groups connected to this Axcess level, as well as the
Axcess level itself.
Example:
SEND_COMMAND DMX,'GC1,2A3'
Connects Groups 1 and 2 to Axcess level 3.
Connecting a single group to a DMX level: The group level changes
immediately to reflect the current DMX input level. The group can now
be ramped up and down by the DMX input level. There are no other
means of affecting the group output.
Example:
SEND_COMMAND DMX,'GC4D5'
Connects Group 4 to DMX input 5.
Connecting multiple groups to a DMX level: The group levels change
immediately to reflect the current DMX input level and behave the
same as connecting a single group to the DMX input.

Group Buffer Commands (Cont.)
Command
Description
GD
The group stop (‘GS’), group ramp down (‘GD’), or group direct ramp
command (‘GR’) will interrupt this command. It is not possible to use
this command on groups that are connected to an Axcess level or to a
DMX input.
Ramps down one or more groups at
the current ramp rate set by the ‘GT’
command.
Syntax:
"'GD<list of groups>'"
The list can be single groups and/or ranges of groups separated by
commas. If this command is sent for multiple groups, only those that
are connected to an Axcess level or DMX input will ramp.
Example:
SEND_COMMAND DMX,'GD1,3-4'
Starts a ramp down on groups 1, 3, and 4.
GE
Erases groups.
Removes all output channels from one or more groups. These outputs
go immediately to 0% in the Group buffer and do not disconnect an
Axcess level or DMX input from the group, if it is currently connected.
If a programmer later adds channels back to the groups, they will be
immediately be connected to the Axcess level or the DMX input.
The list can be single groups and/or ranges of groups separated by
commas.
Syntax:
"'GE<list of groups>'"
Removes all DMX outputs from the groups. Sets all levels in the group
buffer to zero.
Example:
SEND_COMMAND DMX,'GE1'
Removes all output channels from Group 1.
SEND_COMMAND DMX,'GE5,8-10'
Removes all output channels from Groups 5 and 8 through 10.
GF
This is useful for creating “blind” presets, meaning that its not
necessary to drive the actual DMX outputs to these levels in order to

except the Max value for each output is store the preset. All other rules for use are identical to those of the

specified in the Send Command.
Syntax:
"'GF<group>D<special list of DMX outputs with
maximum value>'"
Variables:
group = 1-96
special list of DMX outputs with maximum value = 1-512
Example:
SEND_COMMAND DMX,'GF1D1@100%,2@50%,8@75%'
Adds channels 1,2, and 8 to Group 1 at levels of 100%, 50%, and
75% respectively.
SEND_COMMAND DMX,'GF10D5-10@255,20@50%'
Adds channels 5 through 10 at 100% (255) and channel 20 at 50% to
Group 10.
After the output there is an ampersand (@), then the maximum value
for that output. That means the highest the DMX output can ever be is
the value given at the time of the add. Ranges are allowed but can
only have one maximum value for whole range.

Group Buffer Commands (Cont.)
Command
Description
GL
This command removes one or more output channels from the group
that they are connected to. These outputs go immediately to 0% in the
Group buffer.
Deletes DMX outputs from any group.
DO NOT specify which group these are to be removed from, because
a channel can only be a member of one group at a time.
The list can be single outputs and/or ranges of outputs separated by
commas.
Syntax:
"'GL<list of DMX outputs>'"
Variable:
list of DMX outputs = 1-512
Example:
SEND_COMMAND DMX,'GL1-50'
Removes DMX channels 1 through 50 from any group.
SEND_COMMAND DMX,'GL5,10,20-25'
Removes DMX channels 5, 10, and 20 through 25 from any group.
GO
Sets the current output values in the
Groups to the same value as the
current actual DMX output.
This command copies the actual output levels for the AXB-DMX512
box to the Group buffer for one or more groups.
Syntax:
"'GO<list of groups>'"
This has the effect of copying the highest value from the patch or
direct control buffer into the group buffer if they are higher than the
value in the Group buffer.
This is useful in the event a programmer wishes to add a group and
then ramp it down from its current level. To do this:
Use the Direct or Patch buffer to set the DMX outputs as needed.
Add one or more groups using the ‘GP’ command.
Use group copy (‘GO’) to copy the box outputs to the group buffer
for these groups.
Disconnect the Patch buffer (‘PZ’) or send the Direct buffer (‘DZ’)
to 0%.
Example:
SEND_COMMAND DMX,'GO1'
Copies outputs for all channels in Group 1 to the Group buffer.
SEND_COMMAND DMX,'GO5-8'
Copies outputs for all channels in Groups 5 through 8 to the Group
buffer.
Warning: The ‘GO’ command only works normal
(non-proportional) groups. To work around this, use the direct
ramp (‘DR’) command to set each group to full, instead of using
the ‘GO’ command.

Group Buffer Commands (Cont.)
Command
Description
GP
The highest the DMX output can ever be is the value at the time of the
add. A DMX output can only belong to one group at a time.
Same as ‘GA’ command, except the
DMX outputs are added so they will
remain proportional to the value they
had at the time of adding the output.
The outputs will not ramp to a value above that which they had at the
time they were added. This is the command typically used to store
scenes that were created on a DMX console that is providing the
DMX inputs to the AXB-DMX512 unit. When the group is ramped, the
outputs retain their same proportional level to each other.
Warning: Rounding errors occur in the algorithym that controls the
proportional levels (this function is unsuitable for precision control).
Syntax:
"'GP<group>D<list of DMX output>'"
Variables:
group = 1-96
list of DMX output = 1,2,3,5 -10
If an output is added to an existing group, the its proportional value is
determined by its value when compared to the maximum values for
each channel in a group; not by its value compared to the current
values for each channel in the group.
As with the ‘GA’ command, this can cause things to be a bit out of
sync at the time of adding. When any channel is added, its output
value in the Group Buffer does not change, regardless of what level
other outputs in the group might currently be at.
When ramping up (‘GU’) or down (‘GD’), the other levels will reach
their maximum or minimum before the currently added level does.
Once all levels have reached maximum or minimum, they will ramp
together from that point forward.

Group Buffer Commands (Cont.)
Command
Description
GR
Ramps a single group to a level. Time is optional and if no time is
specified, the group time (set by the ‘GT’ command) is used and then
it will ramp at the current ramp rate for that group. If a group is tied to
a DMX input, then this command is ignored. If the group is tied to an
Axcess level the group will ramp.
Ramps group to a L level in T tenths of
seconds.
This can be interrupted by the group up (‘GU’), group down (‘GD’), or
group stop (‘GS’) commands. Inaccuracies in the value, as a result of
rounding, are common with fixed and proportional groups. Even if the
group is set to 100%, some of the channels will still not be at their
stored levels. The group up (‘GU’) command can be issued to take
the groups to their true 100% level.
Syntax:

Variables
group = 1-96. The group of DMX output that act together. Outputs
can only belong to one group at a time.

Individual Output rates will be proportional.
Sets the current ramp rate for one or
more groups in tenths of a second.
Optionally, the up (‘U’) or down (‘D’) times may be specified. Without
an U or D, both up and down ramp rates are set the same. Ramp
rates determine how long the group will take to ramp from 0% to
100% (and 100% to 0%).
If, for example, there is a ramp time of 10 seconds, and the level is
currently at 50%, it will take only 5 seconds to ramp to either 0% or
100%. 100% for proportional (‘GP’) and fixed (‘GF’) groups is the
maximum level in the group for each channel that is not necessarily
fully at 100% (255).
