Product Information

XB-DMX512 DMX512 Interface

Product Information

The AXB-DMX512 DMX512 Interface creates a bi-directional DMX512 AXlink connection,

transmitting and receiving up to 512 DMX channels for lighting dimmers, spotlights, and other DMX

control applications.

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 DIP switch on the front panel (FIG. 1) sets the AXlink identification number for

the AXB-DMX512. Make sure the device number matches the number assigned in the Axcess software

program.

The following table describes the values on the DEVICE DIP switch.

Terminating the Device

When using the DMX input and if this device is the last device in a chain of DMX512 devices, you must

terminate the line. To terminate the device, position jumpers on jumper pin trios JP4 and JP5 (FIG. 2):

Configuration and Installation

4AXB-DMX512 DMX512 Interface

1. Remove the jumper that is on pins 1 and 2 of jumper trios JP4 and JP5. (Pins 1 and 2 are marked

HIZ - see FIG. 3).

2. Place the jumper on pins 2 and 3 of jumper trios JP4 and JP5. (Pins 2 and 3 are marked TERM -see

FIG. 3). This terminates the incoming DMX input with a 120 ohm resistor.

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.

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 interface uses a PSN2.8 power supply.

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 AXB-DMX512 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.

Using AXlink communication

Connect the AXlink wiring to the connector on the AXB-DMX512, as shown in FIG. 5.

Using IN and OUT DMX512 data communication

1. For transmit wiring, connect the DMX512 wiring to the OUT connector, as shown in FIG. 6.

2. For receive wiring, connect the DMX512 wiring to the IN connector, as shown in FIG. 7.

Mounting the AXB-DMX512 in a Rack

To mount the AXB-DMX512 in an equipment rack, you will need an AC-RK rack mounting kit.

1. Remove the two screws on the front panel of the AXB-DMX512.

2. Remove the front panel and the space bracket behind the panel.

3. Remove the rubber feet on the bottom of the unit, if necessary. Insert a scissors blade or other sharp

object into the side of one of the rubber feet and pull it off. 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.

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.

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.

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.

FIG. 8 Lithium battery and socket

All control commands in AXB-DMX512 memory are lost when the lithium battery is

replaced

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.

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.
