DMX
OPERATION
This section describes how to set up and connect the MX-4 for operation with DMX
controllers.
6
DATA CONNECTION
A reliable data connection begins with the right cable. Standard microphone cable
cannot transmit DMX data reliably over long runs. For best results, use cable
specifically designed for RS-485 applications. Your Martin dealer can supply high
quality cable in various lengths.
CONNECTIONS
The MX-4’s XLR data sockets are wired with pin 1 to ground, pin 2 to signal (cold), and pin 3 to signal + (hot). This is the standard pin assignment for DMX
devices.
One or more adaptor cables may be required to connect the MX-4 to the controller
and/or other lights because many devices have 5-pin connectors and others may
have reversed signal polarity, that is, pin 2 hot and pin 3 cold.

To connect the data link
1 Connect a data cable to the controller’s data output. If the controller has a 5-pin
output, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005).
2Lead the data cable from the controller to the first fixture and plug it into the
data input.
3Connect the output of the fixture closest to the controller to the input of the
next fixture. If connecting to a fixture with reversed-polarity (pin 3 cold), insert
a phase-reversing cable between the two fixtures.
4Continue connecting fixtures output to input. Up to 32 devices may be
connected on a serial link.
5Terminate the link by inserting a male termination plug (P/N 91613017) into the
data output of the last fixture. A termination plug is simply an XLR connector
with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3.
1-CHANNEL DMX OPERATION
The 1-channel DMX mode provides simple remote activation of the MX-4’s standalone programs plus blackout and strobe functions. The 1-channel functions are
shown in Table 5. Each fixture runs its own program and therefore cannot be
synchronized with other fixtures.

6/7 CHANNEL DMX OPERATION
The 6-channel DMX mode provides position control of all effects plus speed
control of the moving mirror. The optional 7-channel mode adds speed control of
the color and gobo wheels.
Lamp powerLamp power can be switched on and off from the controller. When set up for 6- or
7-channel DMX operation, the lamp remains off until a lamp-on command is sent.
Note: A peak of electric current many times the operating current is drawn briefly
when striking a lamp. Striking many discharge lamps at once may cause a voltage
drop that prevents lamps from striking or trips circuit breakers. When striking
multiple fixtures, space lamp-on commands at 5 second intervals.
A hot lamp must be allowed to cool for several minutes before it can be turned back
on. To prevent accidental lamp-off commands, a lamp-off can be executed only
when channel 2 and 3 are set to full.
If a hot lamp does not strike, send the lamp-off command and wait several minutes
before trying again.
ResetAll effects can be reset to their index positions from the controller. The reset
command must be sent for 5 seconds before it takes effect.
ShutterThe shutter opens, closes, and strobes at variable rates from 1.5 to 13.5 Hz.
Stand-aloneWhen stand-alone with music or auto trigger is selected on channel 1, the mirror
moves to random positions using the selected trigger. The color and gobo wheels
can be controlled normally, or, by setting their control channels to full, they can be
set to operate in stand-alone mode as well.
Colors The color wheel provides 15 full-color filters, 2 split-color filters, and an open
position. The wheel may be positioned between 2 positions for additional splitcolor effects. Movement speed can be controlled on channel 7, if enabled.
For stand-alone color action, set channel 2 to a value from 210 to 255 and set
channel 1 to stand-alone with music or auto trigger.
GobosThe gobo wheel provides 19 gobos and an open position. Movement speed can be
controlled on channel 7, if enabled.
For stand-alone gobo action, set channel 3 to a value from 240 to 255 and set
channel 1 to stand-alone with music or auto trigger.
Pan and tiltThe mirror pans 230° and tilts 76.5°. Movement speed is controlled on channel 6,
allowing you to program fades on controllers without cross-fader. If your controller
has cross-faders, and you use them, set channel 6 to the “tracking” speed for best
results.

Page 16
To select DMX mode
1 Disconnect the fixture from power.
2 To select 1-channel DMX mode, set DIP-switch pin 11 to ON.
3To select 6-channel DMX mode, set DIP-switch pin 11 to OFF. Verify that the 6/7
ch. jumper is set for 6 channels. This is the factory configuration. See “Setting
the 6/7-ch. DMX jumper” on page 21.
4 To select 7-channel DMX mode, set DIP-switch pin 11 to OFF. Set the 6/7 ch.
jumper for 7 channels as described on page 21.
Set DIP-switch pin 10 to OFF.
DMX ADDRESS
The DMX address, also known as the start channel, is the first channel used to
receive instructions from the controller. It is set using the DIP-switch.
For independent control, each fixture must be assigned its own address and nonoverlapping control channels. Two MX-4s may share the same address only if they
are to respond identically: they will receive the same instructions and individual
control will not be possible.
Pin 12 is reserved for future use and currently has no function.
To set the DMX address
1Select a DMX mode as described above.
2Select a DMX address for the fixture on your controller.
3 Look up the DIP-switch setting for the address in Table 5.
4 Set pins 1 through 9 to the ON (1) or OFF (0) position as listed in the table.
The MX-4 uses the Philips CDM-SA/T (short-arc, tubular) 150W discharge lamp.
If desired, the GE Arcstream 150 may be substituted. Installing any other lamp maydamage the fixture.
To replace the lamp
WARNING! Wear safety glasses and allow the lamp to cool for at least 5
minutes before removing the lamp.
1Disconnect the fixture from power and allow it to cool.
2Remove 2 screws from the lamp-socket assembly with a Pozidriv #2
screwdriver. Remove the lamp assembly.
3Remove the old lamp from the socket.
4Holding the new lamp by its base (do not touch the glass), insert the lamp pins
squarely into the socket.
5 If your fingers touched the glass bulb, clean it with a clean, lint-free cloth
wetted with alcohol.
6Insert the lamp assembly carefully so that the lamp wires are clear of the fan.
Replace the screws.
To align the lamp
Realignment when changing the lamp may improve performance.
1Strike the lamp and shine the light on a flat surface.
2 Center the hot-spot (the brightest part of the beam) horizontally with small
turns of the top-left adjustment screw using a 3 mm Allen wrench.
3Center the hot-spot vertically with the bottom adjustment screw.
4If there is no hot-spot, adjust the reflector until the light is even.

To orient the Arcstream lamp for maximum life
If using the GE Arcstream lamp, maximum lamp life will be achieved by installing
the lamp so that the arc is parallel with the ground.
This is the case in most installations. If the fixture is installed sideways, however, as
shown to the right, below, the arc will be vertical. Turn the lamp socket 90° to
achieve the ideal burning position.
1 Disconnect the fixture from power and allow it to cool.
2Remove 2 screws from the lamp-socket assembly with a Pozidriv #2
screwdriver. Remove the lamp assembly.
3Remove 2 screws from the lamp socket with a Pozidriv #1 screwdriver.
4 Turn the socket 90°, as shown below, in the direction that results in the least
amount of twist in the wires. Tuck the lamp wires into the notches in the socket
and replace the screws.
5Insert the lamp assembly carefully so that the lamp wires are clear of the fan
and replace the access-plate screws.
6Align the lamp as described above.
