1 INTRODUCTION Thank you for selecting the Martin CX-2. The CX-2 is an automated profile spotlight designed for a 250 watt halogen source. It provides separate color and gobo/effect wheels, continuous electronic dimming, adjustable focus, strobe effects, and multiple control options. CX-2 SAFETY INFORMATION Warning! This product is for professional use only. It is not for household use. This product presents risks of lethal or severe injury due to fire and heat, electric shock, and falls.
To protect yourself and others from burns and fi re • Never attempt to bypass the thermostatic switch or fuses. Always replace defective fuses with ones of the specified type and rating. • Keep all combustible materials (for example fabric, wood, paper) at least 0.1 meters (4 inches) away from the fixture. Keep flammable materials well away from the fixture. • Replace the lamp if it becomes defective or worn out.
2 LAMP The CX-2 comes from the factory with a Philips 500 hour lamp installed. This a 24V, 250W ELC halogen lamp. A high-output 50 hour lamp from Osram is also available. Installing any other lamp may damage the fixture! Allow the lamp to cool for at least 5 minutes before packing and moving the fixture. To avoid possible damage, remove the lamp when shipping the fixture.
3 AC POWER CONNECTION Warning! For protection from dangerous electric shock, the fixture must be grounded (earthed). The AC mains supply shall have overload and ground-fault protection. Important! Check voltage setting before applying power. Do not connect the CX-2 to an electrical dimmer system: doing so can damage the electronics. Before use verify that the fixture’s power supply is correctly tapped for the local AC voltage.
To install a plug on the mains lead The fixture’s mains lead must be fitted with a grounding-type cord cap that fits your power distribution cable or outlet. Consult a qualified electrician if you have any doubts about proper installation. Important! Verify that the feed cables are undamaged and rated for the current requirements of all connected devices before use.
4 INSTALLATION The CX-2 can be fastened directly to a suitable surface or to a rigging clamp by means of its adjustable mounting bracket. Do not lay the fixture flat on its mounting bracket arms or position it so that there is less than 10 cm (4 in.) clearance around the fan and air vents. For maximum lamp life, do not place the fixture directly on or beside a speaker cabinet or other source of strong vibrations. To rig the CX-2 Warning! Always use a secure means of secondary attachment.
5 DATA CONNECTION A reliable data connection begins with the right cable. For best results, use cable specifically designed for RS-485 applications, available from your Martin dealer. CONNECTIONS The data sockets are wired with pin 1 to ground, pin 2 to signal - (cold), and pin 3 to signal + (hot) for compatibility with DMX devices. One or more adaptor cables as shown below may be required for connnection to the controller or other lights.
STAND-ALONE OPERATION 6 The CX-2 may be operated without a controller in stand-alone mode. It may be operated as a single unit or together with other CX-2s in “master/slave” configuration. Several options are available to modify stand-alone operation. These options are selected using the DIP-switch as described below. Important! The CX-2 transmits a signal when DIP-switch pins 2 and 10 are set to ON.
To set the master Important! Set only 1 fixture as master (DIP-switch pin 2 and 10 ON). ON 2 Set DIP-switch pins 3, 5, 6, 7, 8, 9, and 11 to OFF. 1 2 3 4 5 6 7 8 9 10 11 12 ON 1 Set DIP-switch pins 2 and 10 to ON. 1 2 3 4 5 6 7 8 9 10 11 12 3 Select options with DIP-switch pins 1, 4, and 12. To set a sl ave 1 Set DIP-switch 10 to ON. 2 Set pins 1, 2, 3, 4, 5 and 11 to OFF. 3 Select options with DIP-switch pins 6, 7, 8, 9, and 12.
7 MC-1 OPERATION CX-2s with CPU firmware v 1.2 or higher are fully compatible with the Martin MC-1 Controller. See the MC-1 user manual for additional information. MC-1 SETTINGS DIP-switch pin 10 must be set to OFF to enable MC-1 mode operation. Changes to the setting take effect after the fixture has been turned off and on. DIP-switch pins 6, 7, 8, and 9 select several control options that can be combined to achieve powerful effects quickly and easily. Pin 12 selects lamp power and works in all modes.
8 DMX OPERATION This section describes how to select the DMX operation mode and address using the DIP-switch and briefly describes the programmable control options. DMX MODES The CX-2 has 2 DMX modes to choose from: a 1-channel mode that provides control of the built-in stand-alone features, and a 4-channel mode that provides full control of all effects. To select DMX mode 1 Disconnect the fixture from power. Set DIP-switch pin 10 to OFF. 2 To select 1-channel DMX mode, set DIP-switch pin 11 to ON.
Find the address in the table. Read the settings for pins 1 - 5 to the left and read the settings for pins 6 - 9 above the address. “0” means OFF and “1” means ON. Pin 10 is always OFF for DMX operation.
1-CHANNEL DMX OPERATION The functions shown in the following table are available in 1-channel mode. When a “stand-alone” function is selected, the fixture steps through a routine using a built-in microphone to trigger the action to the beat of the music. Note that multiple fixtures cannot be synchronized in this mode.
BASIC 9 SERVICE The CX-2 requires simple routine maintenance. The maintenance schedule depends heavily on the operating environment; please consult a Martin service technician for recommendations. Any service procedure not described here should be referred to a qualified technician. Important! Excessive dust, grease, and smoke fluid buildup degrades performance and causes overheating and damage to the fixture that is not covered by the warranty.
To clean the fan and air vents To maintain adequate cooling, dust must be cleaned from the fan and air vents periodically. 1 Remove the data and power cables and stand the fixture on end. 2 Remove dust and dirt from the fan blades and vent grills using a soft brush, cotton swab, vacuum, or compressed air. REPLACING FUSES The CX-2 has 2 fuses. The main fuse holder is built in to the mains input socket. The secondary fuse is located on the printed circuit board.
10 TROUBLESHOOTING Problem One or more of the fixtures is completely dead. Probable cause(s) No power to fixture. Remedy Check that power is switched on and cables are plugged in. Primary fuse blown. Replace fuse. Secondary fuse blown. Replace fuse. Fixtures reset correctly but all respond erratically or not at all to the controller. The controller is not connected. Connect controller. XLR pin-out of the controller does not match pin-out of the first fixture on the link (i.e. signal is reversed).
