The CX-2 uses a 24V, 250W ELC halogen lamp. Two models are available, an
economical 300 hour lamp from Philips and a high-output 50 hour lamp from
Osram. Installing any other lamp may damage the fixture.

Allow the lamp to cool for at least 5 minu tes before packing and moving t he
fixture. To avoid possible damage, remove the lamp when sh ipping the fixture.

To install a lamp in the CX-2

Warning! Always disconnect t he

fixture from AC power
and allow the fixture to
cool for 5 minutes
before installi ng a n ew
lamp.

1 Disconnect the fixture from

AC power. If replacing a hot
lamp, allow it to cool for 5
minutes before removing the
cover. The lamp cools faster
with the cover in place.

2 Release the 4 cover locks by

turning them a quarter-turn
counterclockwise. Lift the cover straight off.

3 To remove the lamp, grasp it by the reflector and pull it out of the holder. Pull

the socket straight back off the metal pins. Do not pull the wires.
4 Push the socket fully onto the pins of the new lamp.
5 Gently push the lamp into the holder until it snaps into place.
6 Replace the top cover. To lock the 4 cover locks, turn them a half to a quarter

turn clockwise until you feel them click.

This section describes how to select the DMX address and special settings using
the DIP-switch on the end panel.

Important ! Disconnect t he fixt ure from AC power befor e changing the

DIP-switch setting. Changes take effect after the fixture has
been turned off and back on.

DMX ADDRESS SELECTION

If the CX-2 is to be used with a DMX protocol controller, then the DIP-switch
must be set to a D MX control address. The addre ss, also known as the start
channel, is the first channel used to receive instructions from the controller. The
CX-2 uses 4 channels for full DMX operation. For independent control, each
fixture must be assigned its own address and non-overlapping control channels.
Two CX-2s may share the same address only if they are to respo nd ident ically:
they will receive the same inst ruc tio ns and individual control will not be possibl e.

To set the DMX address

1 Select an address for the fixture on your controller.
2 Look up the DIP-switch setting for the address on page 11.
3 Disconnect the fixture from AC power.
4 Set pins 1 through 9 to the ON (1) or OFF (0) position as listed in the table.
5 Set pin 10 to the OFF position.
6 Set pin 11 to the OFF position for full 4-channel DMX operation or to the ON

position for 1-channel DMX operation.

ATA CONNECTION

7

This section describes how to connect fixtures to a controller.

RECOMMENDED CABLE

A reliable data connection begins with the right cable. Standar d microphone

cable cannot transmit DMX data reliably over long runs. For best results, use

cable specifically designed for RS-485 applicatio ns. Your Ma rtin dealer can

supply high quality cable in various lengths.

CONNECTIONS

The CX-2’s XLR data sockets are wired with pin 1 to gr ound, pi n 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 CX-2 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 controller has a 5-pin

output, use a 5-pin male to 3-pin fem ale adaptor cable (P/N 11820005).

2 Lead the data cable from the controller to the first fixture. Plug the cable into

the fixture’s data input.

3 Connect the output of the fixture closest to the controller to the input of the

next fixture. If connecting to a fixtu re with reversed-polarity (pin 3 cold),
insert a phase-reversing cable between the two fixtures.

4 Continue connecting fixtures output to input. Up to 32 devices may be

connected on a serial link.

5 Terminate 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.

FULL DMX OPERATION

For DMX operation, the CX-2 must be connected to a DMX controller as

described under “Data connection” on page 13. DIP-switch pins 1 - 9 must be set

to the DMX address as described on page 10. Pins 10 an d 11 must be set to OFF.

DMX CHANNEL DESCRIPTION

See also the DMX protocol on page 21.

Channel 1 controls the light intensity and the strobe rate. It also allows you to

execute a “stand-alone” program with random color and gobo change using

automatic or music trigger.

All effect wheels are reset to their home position when the fixtur e is powered up;

they can also be reset from the controller by sending a reset command on channel

1.

Channel 2 controls the position of the color wheel. When set to 100 percent, the

wheel moves to random positions using the trigger selected on channel 1.

Channel 3 controls the position of the gobo wheel. When set to 100 pe rcent, the

wheel moves to random positions using the trigger selected on channel 1.

Channel 4 controls the speed of effect wheel rotation, allowing you to vary the

speed on controllers without cross-faders. If your controller has cross-faders, and

you use them, then set channel 4 to t he “t racking” speed (0 percent).

1-CHANNEL DMX OPERATION

The CX-2 may be operated in 1-channel mode with the MC-1 or any DMX

controller. For 1-channel operation, connect the controller as described on page

13.

DIP-switch pin 11 must be set to ON.

If using the MC-1, select DMX channel 1. If using a

DMX controller, any channel within the controller’s

range may be assign e d.

ìíë ê é èì åç æ ä21ìëìì

16 Operation CX-2 user manual

The single-channel functions are shown below.

STAND-ALONE OPERATION

The CX-2 automatically operates in stand-alone mode with music trigger if there
is no control signal.

Operation can be modified using the special settings described on page 12. To
enable the special settings, DIP-switch pin 10 must be ON.

Important! The fixture transmits control signals on the data link when

operated in stand-a lone mo de (wi th DIP -switch pin s 2 an d 10
ON). To prevent damage to the electronics , do n ot con nect a
stand-alone fixture to o ther st and-al one fixt ures or to a
controller.

MASTER / SLAVE OPERATION

Multiple CX-2s can be connected together, without a controller, for synchronized
“master/slave” operation in which the slave fixtures mimic the behavior of the
master fixture.

To connect units for master / slave operation

1 Disconnect all fixtures from AC power.
2 Connect the output of one CX-2 to the input of the next CX-2.
3 Connect additional CX-2s output to input. Up to 32 may be connected.
4 Terminate the link on both ends by inserting a female termination plug into

the data input of the first fixture and a male termination plug 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.

The CX-2 requires simple routine maintenance. The main tenance schedule
depends heavily on the oper ating environment; ple ase consult a Ma rtin service
technician for recommendations.

Any service procedure not described here should be ref erred to a qualified
technician.

Important ! E xcessi ve dust, greas e, and smoke fluid buildup de grades

performance and causes overheatin g and damage to th e
fixture that is no t covered by the warrant y.

Warning! Disconne ct the fixtur e from AC power before removing a ny

cover.

CLEANING

To clean optical components

Use care when cleaning optical components. The surface of the color filters is
fragile and small scratches may be visible.

1 Disconnect the fixture from AC power and allow the components to cool

completely.

2 Release the 4 cover locks by turning them a quarter-turn counterclockwise.

Lift the cover straight off.

3 Blow or vacuum away loose dust. Rem ove residues from lenses and filters

with a soft clot h or cotton swabs wetted with isopropyl alcohol. Regular glass
cleaner may also be used, but no residues may remain.

4 Rinse with distilled water. Mixing the water with a small amount of wetting

agent such as Kodak Photoflo will help prevent streaking and spot ting.
5 Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
6 Replace the top cover. To lock the 4 cover locks, turn them a half to a quarter

turn clockwise, until you feel them click.
