Onboard processing and memory can create and store channel groups, faders, patches, and up to 72 presets. A DMX lighting board can operate in tandem with the AXB-DMX512, generate levels for storing presets, or pass through the AXB-DMX512 for direct control of channels.

Configuration and Installation Setting the Device DIP Switch The 8-position DEVICE the AXB-DMX512. Make sure the device number matches the number assigned in the Axcess software program. DEVICE AXlink Device ID DIP Switch Axlink activity LED FIG. 1 AXB-DMX512 (front view)
FIG. 3). This terminates the incoming DMX input with a 120 ohm resistor. FIG. 3 Termination jumper pin settings for JP4 and JP5 Wiring Devices to the AXB-DMX512 The AXB-DMX512 has three captive-wire connectors on the rear panel (FIG. 4) for DMX512 transmit and receive, and AXlink.

Do the same to remove the other three rubber feet. 4. Place the unit in the appropriate opening in the AC-RK. 5. Place the front panel of the AXB-DMX512 on the front of the rack over the unit and secure the screws. AXB-DMX512 DMX512 Interface...
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.
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.
Example: SEND_COMMAND DMX,'DR-512L50%T10' Sends all channels to 50% in 1 second. SEND_COMMAND DMX,'DR-512L127T25' Sends all channels to 50% in 2.5 seconds. SEND_COMMAND DMX,'DR10,20-30,35L0T0' Sends channels 10,20 through 30, and 35 to 0%. AXB-DMX512 DMX512 Interface...
Patch Buffer Send_Commands Command Patches inputs 1-512 in a one-to-one relationship with outputs 1-512. AXB-DMX512 DMX512 Interface Description This is the final output of the DMX512 box and is also affected by the values in the Patch and Group Buffers.
Page 14
Unpatches all DMX outputs (the same as the ’PZ’ command). SEND_COMMAND DMX,'PX15,20-25' Unpatches DMX outputs 15 and 20 through 25. Global delete all DMX outputs from any DMX input. Syntax: "'PZ'" All DMX outputs in the Patch Buffer immediately go to zero. AXB-DMX512 DMX512 Interface...
Group Buffer Commands Command 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.
Page 16
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. Example: SEND_COMMAND DMX,'GC1-3,5D8' Connects Groups 1 through 3 and 5 to DMX input 8. AXB-DMX512 DMX512 Interface...

Functions like the ‘GP’ command, except the Max value for each output is specified in the Send Command. AXB-DMX512 DMX512 Interface Description 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.
Page 18
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. 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>'"...
Page 19
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.
Page 20
Stops ‘GU’,’GD’,’GR’. Syntax: "'GS<list of groups>'" The list can be single groups and/or ranges of groups separated by commas. DMX outputs freeze at their current level. Example: SEND_COMMAND DMX,'GS1,3-4' Stops a ramp on Groups 1, 3, and 4. AXB-DMX512 DMX512 Interface...

Ramps up one or more groups at the current ramp rate set by the ‘GT’ command. AXB-DMX512 DMX512 Interface Description This affects any future group up (‘GU’), group down (‘GD’), or group direct ramp (‘GR’) commands. The specified time determines how long it takes to go full range.
Page 23
Ramps a single Axcess level to the chosen L level in T tenths of seconds. Stops any ramp that was initiated. AXB-DMX512 DMX512 Interface Description Ramps until ‘AS’, ‘AR’, or ‘AU’. Note that it is not possible to ramp an Axcess level if it has not been connected to a DMX input (using the ’AC’...
Causes a string to be sent to the master. Example: SEND_COMMAND DMX,'MG1?' Sent to the AXB-DMX512 box. The box replies “‘MG1@255’,13,10” indicating that DMX outputs in Group 1 are at full (255). SEND_COMMAND DMX,'MG2?' Sent to the AXB-DMX512 box. The box replies “‘MG2@127’,13,10”...

Variable: DMX Output = 1-512 Example: SEND_COMMAND DMX,'MO1?' Sent to the AXB-DMX512 box. The box replies “‘MO1@255’,13,10” indicating that DMX output 1 is at 100% (255). SEND_COMMAND DMX,'MI2?' Sent to the AXB-DMX512 box. The box replies “‘MO2@127’,13,10” indicating that DMX output 2 is at 50% (127).
‘ML, and ‘MM’ to send either 44 or 22 packets per second with 512 channels of DMX outputs. Resets everything. Channel Commands The following table lists the channel commands for the AXB-DMX512: Channel Commands Channel Command Axcess level 1-9 ramp up 9-16...
The AXB-DMX512 is connected between a lighting console and the dimmers. If I bypass the AXB-DMX512 box, I have control of the dimmers, but when I put the box in the system, I have no control.
