Installation Guide
AXB-DMX512
DMX512 Interface
Overview
The AXB-DMX512 DMX512 Interface (
FG5927
) 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.
Specifications
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):
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 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.

Front panel components:
LED Indicators
• AXlink LED (green and blinks to indicate AXlink
communication activity and power:
Full-Off
indicates no power is being received or the
controller is not functioning properly.
One blink per second
indicates power is active and
AXlink communication is functioning.
Full-On
indicates there is no AXlink control or activity,
but power is On.
• RX LED (red) indicates the AXB-DMX512 is receiving
DMX512 data. Corresponds to the IN and OUT ports
on the rear panel.
• TX LED (red) indicates the AXB-DMX512 is
transmitting DMX512 data. Corresponds to the IN and
OUT ports on the rear panel.
DIP switch
• 8-position DEVICE DIP switch sets the AXlink address
(Device ID) for the AXB-DMX512.
• The DIP Switch to the right of the DEVICE DIP is
reserved - no settings are required.
