D section 1 SAFETY Thank you for selecting the Martin MAC 250 or the MAC 250+. Both the MAC 250 and the MAC 250+ are yokemounted profile spotlights that are designed around a 250 watt discharge lamp. They provide: · · · · · · · 12 saturated dichroic colors 8 replaceable rotating gobos 3-facet rotating prism variable focus strobe effects 0 to 100% dimming accurate 16-bit movement. In addition, the standard MAC 250 provides 4 user-configurable beam angles from 12.1° to 23.3°. The MAC 250+ provides gobo indexing, interchangeable color filters, and an 18.3° achromatic lens system. High-performance optics, attractive design, modular construction and numerous user-friendly features make these Martin fixtures well suited for any effect lighting application calling for a compact, hard-focusing 250 watt fixture. Safety precautions The MAC 250 and MAC 250+ are for professional use only. They are not for household use. They present risks of injury due to electric shock, heat and ultraviolet radiation burns, lamp explosion, falls, high-intensity light, and fire. Read this manual before powering or installing the fixture, follow the safety precautions listed below and observe all warnings in this manual and printed on the fixture. If you have questions about how to operate the fixture safely, please contact your Martin dealer or call the Martin 24-hour service hotline for assistance. · · · · · · ALWAYS disconnect the fixture from AC power before removing or installing the lamp, fuses, or any part; and when not in use. Allow the fixture to cool for at least 5 minutes before replacing the lamp. Keep all combustible materials (for example fabric, wood, paper) at least 0.3 meters (12 inches) away from the fixture. Keep flammable materials well away from the fixture. For protection against dangerous electric shock, always ground (earth) the fixture electrically. Use only a source of AC power that complies with local building and electrical codes. Do not expose the fixture to rain or moisture. Ensure that the air flow through fans and vents is free and unobstructed. When suspending the fixture above ground level, verify that the structure can hold at least 10 times the weight of all installed devices and secure the fixture with an approved safety cable. Block access below the work area whenever installing or removing the fixture. Refer any service operation not described in this manual to a qualified technician. Do not illuminate surfaces within 0.3 meters (12 inches) of the fixture. Never place filters or other materials over the lens. Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F). Replace the lamp as soon as it becomes defective or worn out, or before usage exceeds the maximum service life. Do not stare directly into the light. Never operate the fixture without all lenses and covers installed: an unshielded lamp can explode without warning and emits dangerous UV radiation that can cause burns and eye damage. Do not modify the fixture or install other than genuine Martin accessories and upgrade kits. · · · · · · · · Safety 3 section 2 SETUP Unpacking The MAC 250 and MAC 250+ come with: · · · · 1 1/4-turn clamp mounting bracket 1 5-meter, 3-pin shielded XLR control cable 1 3-meter, 3-wire IEC power cable 1 user manual The packing material is carefully designed to protect the fixture during shipment - always use it or a custom flight case to transport the fixture.

Disconnect the fixture from AC power and allow the lamp to cool for at least 5 minutes before proceeding. Wear safety goggles to protect your eyes. reflector alignment screws lamp socket assembly Figure 1: Lamp installation 4 MAC 250 and MAC 250+ To i n s t a l l a l a m p 1. Remove the 2 Phillips screws from the lamp socket assembly. Pull the lamp and socket out of the head. 2. Remove the old lamp, if any, from the socket. 3. Holding the new lamp by its ceramic base (do not touch the glass), align the small pin with the small hole and insert the lamp squarely into the socket. Make sure that the 4 small projections on the base contact the face of the socket. 4. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touched the glass. A clean, lint-free cloth wetted with alcohol may also be used. 5. Gently insert the assembly, making sure the lamp fits through the opening in the reflector. Replace the 2 screws. 6. The reflector is pre-adjusted at the factory; however, precise alignment to compensate for variations between lamps may improve performance. See "Optimizing reflector alignment" on page 15. Pow e r i n g WA R N I N G ! For protection from dangerous electric shock, the fixture must be grounded (earthed). The AC mains supply shall be fitted with a fuse or circuit breaker and ground-fault protection. 1. Verify that the voltage and frequency settings match the local AC supply. The factory settings are printed on a label under the base. Check Table 7 on page 20 to verify that these settings are correct for your local AC voltage. Operating at the incorrect power setting can result in poor light output, greatly reduced lamp life, overheating and damage to the fixture. Refer to "Changing voltage and frequency settings" on page 20 if the settings need to be adjusted. 2. Install a grounding-type cord cap that fits your supply on the power cable. Following the manufacturer's instructions, connect the yellow/green wire to the ground (earth) pin, the blue wire to the neutral pin, and the brown wire to the live pin. The table shows some possible pin identification schemes; if the pins are not clearly identified, or if you have any doubts about proper installation, consult a qualified electrician. Wire brown blue yellow/green Pin live neutral ground Marking "L" "N" Screw (US) yellow or brass silver green Table 1: Cord cap wiring 3. Verify that the supply cable is undamaged and rated for the current requirements of all connected devices. 4. Plug the prepared power cable into the 3-prong IEC inlet and a grounded AC power supply. Do not connect the fixture to a dimmer system. Setup 5 Rigging The MAC 250 and MAC 250+ include a clamp mounting bracket to which 1 or 2 rigging clamps (not included) can be bolted. The clamp mounting bracket fastens to the base as shown with 1/4-turn fasteners. Figure 2: Clamp mounting bracket WA R N I N G ! Always use an approved safety cable. The 1/4-turn fasteners are locked only when turned fully clockwise. 1. Verify that the clamps are in good condition and can bear at least 10 times the weight of the fixture. Bolt clamps to the bracket with a grade 8.8 (minimum) M12 bolt and lock nut, or as recommended by the clamp manufacturer, through the 13 mm holes in the clamp mounting bracket. 2. Align the clamp mounting bracket with any 2 key slots on the base. Insert both locking pins into the slots and turn both levers a full 1/4 turn clockwise to lock. 3. Verify that the structure can bear at least 10 times the weight of all installed fixtures, clamps, cables, auxiliary equipment, etc. 4. Working from a stable platform, clamp the fixture to the structure. 5. Install a safety cable that can bear at least 10 times the weight of the fixture securely to the structure and anchor the cable to the dedicated attachment point on the base. The attachment point is designed to fit a carabiner clamp. Connecting the serial data link The MAC 250 and MAC 250+ have locking 3-pin data input and output sockets that are wired for use with DMX devices, that is, pin 1 to shield, pin 2 to cold (-) and pin 3 to hot (+). As some devices have 5-pin connectors, or 3-pin connectors with reversed polarity on pins 2 and 3, the following adaptor cables may be required. 5-pin to 3-pin Adaptor Male 1 2 3 4 5 Female 1 2 3 3-pin to 5-pin Adaptor Male 1 2 3 Female 1 2 3 4 5 3-pin to 3-pin Phase-Reversing Adaptor Male 1 2 3 Female 1 2 3 P/N 11820005 P/N 11820004 P/N 11820006 Figure 3: Cable adaptors 1. Connect the controller's output to the fixture's data input. For a DMX controller with 5-pin output, use a cable with a 5-pin male and a 3-pin female connector, such as P/N 11820005. For a DMX controller with 3pin output, use a 3-pin cable such as the one included. For a Martin RS-485 protocol controller, use a phase reversing cable or reconfigure the pin-out as described on page 19. 2. Connect the output of the fixture closest to the controller to the input of the next fixture. When connecting a fixture with pin 3 hot to a fixture with pin 3 cold, use a phase-reversing adaptor. 3. To terminate the link, insert a male 120 XLR termination plug in the output of the last fixture. 6 MAC 250 and MAC 250+ Tips for building a serial link · Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot transmit DMX data reliably over long runs. For links up to 300 meters (1000 ft.) long, you can use 24 AWG, low capacitance, 85-150 ohm characteristic impedance, shielded cable with 1 or more twisted pairs. For runs up to 500 meters (1640 ft.) use 22 AWG cable. Use an amplifier if the serial link exceeds 500 meters. Never use a "Y" connector to split the link. To split the serial link into branches use a splitter such as the Martin 4Channel Opto-Isolated RS-485 Splitter/Amplifier. Do not overload the link. Up to 32 devices may be connected on a serial link. Terminate the link by installing a termination plug in the output socket of the last fixture on the link. The termination plug, which is simply a male XLR connector with a 120 ohm, 0.25 watt resistor soldered between pins 2 and 3, "soaks up" the control signal so it does not reflect back down the link and cause interference. If a splitter is used, terminate each branch of the link. · · · Setup 7 section 3 C O N T RO L PAN E L You set the fixture address, mode, and personalities; read lamp hours, DMX values, and other information; calibrate effects, control the fixture manually, and run test and demo programs from the LED control panel.

DMX mode 4 provides full control and is recommended unless channels are limited. See "DMX-512 control" on page 12 for factors to consider when selecting other DMX modes. The address, also known as the start channel, is the first channel used to receive instructions from the controller. For independent control, each fixture must be assigned its own address and non-overlapping control channels. Two fixtures 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. If automatic protocol detection (A UTO ) is O N, the fixture automatically switches to DMX or Martin mode after interpreting the control signal. This allows you to set the fixture up for both DMX and Martin controllers. If it is O FF, the default, the operating mode must match the controller. Note: automatic protocol detection does not detect the DMX mode (1, 2, 3, or 4) setup on the controller. 1. Apply power to the MAC 250 or MAC 250+.

Control Panel 11 section 4 OPERATION This section describes the effects and how personality settings affect their behavior. Selecting personalities from the control panel is described in the previous section. DMX-512 control The MAC 250 and MAC 250+ can be operated with DMX-512 controllers in 4 modes that combine vector and/or tracking control with 8-bit or 16-bit pan/tilt resolution. Tr a c k i n g c o n t r o l With tracking control, the speed at which effects move is set by programming a cross-fade time on the controller. The controller divides the move into steps and updates the fixture with small changes at the rate required to achieve the fade. The fixture tracks the changes and averages them with a digital filter algorithm to provide smooth movement at all speeds. This algorithm is adjustable to compensate for controllers that calculate position changes unevenly. In most cases the default settings work well. If movement is not satisfactory there are 2 parameters that can be adjusted. The first is the calculation method used and is selected under PE RS/ TRA C/M OdE. MOd 1, the default, calculates speed based on the absolute value of the change in DMX; it is the best choice with controllers that calculate intermediate positions that are close to the line of travel. MOd 2 uses the real value of the DMX delta to calculate speed and is better if the intermediate positions stray significantly from the line of travel. The second parameter is the number of position updates used to calculate speed. The level is adjustable between 1 and 10 under PE RS/ TRAC /CA L. Increasing the number of samples increases the distance over which speed is calculated, making movement smoother but less responsive to sudden changes. The ideal settings for both parameters will vary from controller to controller: experiment for best results. Ve c t o r c o n t r o l With vector control, you set the speed on a speed channel. This provides a way to control speed on controllers without cross-faders. Vector control also provides smoother movement, particularly at slow speeds, with controllers that send slow or irregular tracking updates, plus a "blackout speed" and overrides of the shortcut and pan/tilt speed personality settings. When using vector speed, the cross-fade time must be 0. Tracking control can be enabled in vector mode by setting one or both of the speed channels to "tracking speed." 8-bit versus 16-bit pan/tilt resolution With 8-bit pan/tilt resolution, pan and tilt are divided into 256 equal increments. Finer position control and smoother movement are provided in 16-bit mode, which divides pan into 40,192 positions and tilt into 43,008 positions. Mar tin RS-485 con trol The MAC 250 is fully supported by the Martin 3032 controller with version 2.05 or higher software. The MAC 250+ may be set up on the 3032 as a MAC 250: gobo indexing, however, is not supported. To respond to the 3032, Martin mode must be selected or automatic protocol detection must be enabled as described on page 10. Controllable effects All mechanical effects are reset to a home position when the fixture is powered up. They can also be reset via DMX. Accidental resets can be prevented by turning DMX Reset (P ERS /dR ES ) off. An on-the-fly position correction system automatically corrects the position of the color and gobo wheels; this feature can be disabled by turning Effects Feedback (P E RS/ EFFb ) off. General operation may be optimized for speed or quietness with the Studio Mode setting (P ER S/S TUd). Lamp With the default setting, the lamp remains off until a "lamp on" command is sent from the controller. Note: A peak of electric current that can be many times the operating current is drawn for an instant when striking a discharge lamp. Striking many lamps at once may cause a voltage drop large enough to prevent lamps from striking or draw enough 12 MAC 250 and MAC 250+ current to trip circuit breakers. If sending "lamp on" commands to multiple fixtures, program a sequence that strikes lamps one at a time at 5 second intervals. The fixture automatically strikes the lamp within 90 seconds of being powered on if the Automatic Lamp On setting (P ER S/AL ON ) is turned on. A delay determined by the fixture address staggers lamp strikes to prevent excessive voltage drop and current draw. The lamp can be turned off from the controller. Note: the lamp cannot be restruck for 8 minutes after being turned off. Accidental "lamp off" commands can be prevented by turning the DMX Lamp Off setting (P ER S/d LOF) off. Color .

The wheel can be scrolled continuously - allowing for split color effects - or in steps, and rotated randomly or continuously in both directions at different speeds. The Shortcuts setting (P E RS/S CUT ) determines whether or not the wheel takes the shortest path to the next position; this setting may be overridden on the speed channel in vector mode. Setting the effects speed to "blackout" causes the shutter to black out the light while the wheel is moving. The color filters on the MAC 250+ are interchangeable. See page 16. Rotating gobos . Position 1 2 3 4 5 6 7 8 Gobo Radial Dashes Line of Beams Fan Hat Triple Beam Decentered Beam Fibroid Random Holes, Blue Psycho Circles, Magenta Table 5: Gobo positions The MAC 250 and MAC 250+ has 8 rotating gobo positions plus an open position. Each gobo rotates and/or "shakes" at varying speeds. Gobos and shake are selected on channel 4; rotation is set on channel 5. The gobo wheel also rotates continuously in both directions at variable speed. Operation 13 The MAC 250+ provides gobo indexing as well. Select the gobo on channel 4, between the DMX values of 5 and 44, and set the position on channel 5. The gobo type setting (P ERS /GTY P) automatically defaults to IN dX in the MAC 250+ to enable this feature. It defaults to S Td in the MAC 250. The Shortcuts setting (P E RS/S CUT ) determines whether or not the wheel takes the shortest path to the next position; this setting may be overridden on the effects speed channel. Setting the speed to "blackout" causes the shutter to black out the light while the wheel turns. To change the gobos, see "Rotating gobos" on page 15. Dimmer / shutter The mechanical dimmer/shutter system provides full, high-resolution dimming, "instant" open and blackout, random and variable strobe effects, and random and variable pulses in which the dimmer snaps open and slowly dims or snaps closed and slowly opens. Pulse and random strobe effects can be disabled by switching DMX Macros (P ER S/ dMA C) off. The Dimmer Mode (P ER S / dMO d) setting allows you to select between linear or simulated tungsten fade curves. The fade time must be 0 to simulate tungsten dimming. Focus The beam may be focused from approximately 2 meters (6.5 feet) to infinity. The MAC 250's default beam angle is 17.5°; see page 17 for additional options. The MAC 250+ has a different optical system that uses achromatic lenses. It provides a beam angle of 18.3°. Rotating prism The 3-facet prism rotates in both directions at varying speeds. There are 8 preprogrammed macros that combine prism and gobos. These can be disabled by switching DMX Macros (P E RS/d MAC ) off. Setting the speed to "blackout" causes the shutter to black out the light while the prism moves in and out. Pa n a n d til t The yoke pans 540° and the head tilts 289°. Movement may be optimized for speed by setting the pan/tilt speed setting (P ER S / PTSP ) to FAS T, or for smoothness by setting it to SLOW. This setting may be overridden on the speed channel in vector mode. Setting the speed to "blackout" causes the shutter to black out the light while the head is moving. The pan and tilt channels can be inverted and/or swapped using the pan/tilt menu (P E RS / PAT I ). 14 MAC 250 and MAC 250+ section 5 BASIC SERVICE The MAC 250 and MAC 250+ operate under challenging conditions presented by heat, humidity, dust, and touring. Excessive dust, grease, and smoke fluid buildup degrades performance and causes overheating and damage that is not covered by the warranty. The MAC 250 and MAC 250+ require regular maintenance to keep performing at their peak. The schedule will depend on the application and should be discussed with your Martin distributor. Refer any service that you are not qualified to perform to a professional technician. WARNING! Removing covers exposes dangerous live electrical circuits, hot surfaces, and a lamp under high pressure. Procedures requiring the removal of any cover shall be performed by professional users or technicians only. Disconnect the fixture from AC power and allow it to cool before removing any cover. Replacing the lamp If the lamp becomes difficult to strike, it probably needs to be replaced. To reduce the risk of lamp explosion, which may damage the fixture, do not exceed the lamp's rated life (2000 hours) by more than 25 percent. Refer to page 5 for the lamp replacement procedure. After installing the lamp, reset the lamp usage counters as described on page 10. Optimizing reflector alignment The reflector is aligned at the factory. Due to differences between lamps, however, fine adjustment may improve performance. 1. Strike the lamp and focus the light on a flat surface. 2. See Figure 1 on page 4. Center the hot-spot (the brightest part of the beam) by turning the 3 adjustment screws one at a time with a 3 mm Allen wrench. If there is no hot-spot, adjust the reflector until the light is even. 3. To reduce a hot-spot, "push" the reflector out by turning all 3 screws counterclockwise 1/4-turn at a time until the light is evenly distributed. 4. If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back in the reflector. "Pull" the reflector in by turning the screws clockwise 1/4-turn at a time until the light is bright and evenly distributed. Figure 5 Rotating gobos Custom glass gobos for the MAC 250 and MAC 250+ should be made with any non-reversible graphics true on the coated side. Complete gobo specifications are listed on page 27. Do not use chrome-coated glass gobos: they absorb more heat than enhanced aluminum gobos and are likely to break or oxidize. Changing gobos 1. Disconnect the fixture from AC power and allow it to cool. Remove the top head shell as shown in Figure 5. 2. Turn the gobo wheel until the gobo lines up with the access hole. Squeeze the ends of the retention spring together and remove. Push the gobo out from the back. 3. Insert the new gobo. See Figure 7 for proper orientation. 4. Replace the gobo retention spring. Figure 6 Basic Service 15 Gobo orientation Figure 7 shows the correct orientation for different gobo types. When in doubt, install gobos with the more reflective side towards the lamp. Coated side towards lamp Coated Glass Gobos Uncoated side towards stage When an object is held up to the coated side there is no space between the object and its reflection. The back edge of the gobo cannot be seen when looking through the coated side. When an object is held up to the uncoated side there is a space between the object and its reflection. The back edge of the gobo can be seen when looking through the uncoated side.

Disconnect the fixture from AC power and allow it to cool. 2. Remove the top head shell as shown in Figure 5. 3. Turn the color wheel so the desired color filter is in front of the access hole. Press the filter forwards slightly to release it and then grasp it by the edges and remove. 4. To insert a filter, slide it under the retention spring until it snaps into place. 5. Replace the top head shell. Figure 8 16 MAC 250 and MAC 250+ C o n f i g u r i n g t h e o p t i c a l s y s t e m ( M AC 2 5 0 o n l y ) Beam angle options The standard MAC 250 lens system can be configured for 4 beam angles ranging from 12.1° to 23.3°. The beam angle in the default 4-lens configuration is 17.5°. Other beam angles are achieved by removing lenses and positioning the dimmer module as shown below. Note: dimming will be somewhat less even in the 12.1° configuration. To calculate the projected size of an image, divide the gobo's image diameter by the focal length and then multiply by the distance in meters. 12.1° 14.6° 17.5° 23.3° 2 34 1 34 12 34 12 4 Figure 9: MAC 250 optical configurations Beam Angle 12.1° 14.6° 17.5° 23.3° Focal Length 80.2 mm 66.3 mm 55.2 mm 41.2 mm Remove Lens 1 (40 mm) 2 (50 mm) 3 (60 mm) Dimmer Position forward forward rear rear Table 6: MAC 250 optical configurations Changing beam angle Verify that lenses and retention springs are fully seated. 1. Disconnect the fixture from AC power and allow it to cool. 2. Remove the top head shell as shown in Figure 5. 3. Remove and/or replace lenses as required. To remove lens 1, first remove lens 2 as described next. Then pull out the retention spring for lens 1 and tilt the module or head until the lens drops out. Catch it in a soft cloth. Store the lens together with the spring in a safe place. Replace lens 2 and the module(s). To remove lens 2, remove either the color/gobo/focus module or the dimmer and prism modules as described below. Pull out the retention spring for lens 2 and tilt the module or head until the lens drops out. Catch it in a soft cloth. Store the lens together with the spring in a safe place. Replace the module(s). To remove lens 3, pull the lens clip back. Tilt the head until the lens drops out and catch it with a soft cloth. Store the lens together with the spring in a safe place. 4. Move the dimmer module to the forward or rear position as indicated in Figure 9. Make sure as you position the module that the bottom sits between the guide pins in the bottom shell. Pull the locking pins up and then snap them down to lock. 5. Replace the head cover. Position the holes by the lens opening over the nipples and check that all wires are inside the head as you lower the cover into place. Push the locking pins in with a flat-tip screwdriver and turn them clockwise until they lock (1/2 turn). Basic Service 17 Removing modules Color/gobo/focus module 1. Disconnect the fixture from AC power and allow it to cool. 2. Remove the top head shell as shown in Figure 5. 3. MAC 250: Unplug the wires from the color and gobo wheel sensors and the 3 top motors. MAC 250 +: Unplug the wires from the color wheel sensor and the 3 top motors. Unplug the outside connector from the junction print behind the gobo wheel. 4. Pull up the 2 plastic locking pins to release the module. Move the starter wires aside and lift the module partially out. Unplug the wires from the bottom motor. Dimmer module 1. Disconnect the fixture from AC power and allow it to cool. 2. Remove the top head shell as shown in Figure 5. 3. Note whether the module is in the forward or rear position. (The MAC 250 + gives best results with the dimmer in the forward position.) 4. Unplug the wires from the top dimmer motor. Pull up the 2 plastic locking pins to release the module. Unplug the wires from the bottom motor. Prism module 1. Disconnect the fixture from AC power and allow it to cool. 2. Remove the top head shell as shown in Figure 5. 3. Remove the dimmer module. 4. Pull the 2 plastic locking pins to release the prism module. Lift the module partially out and unplug the wires from motors. Cleaning Optical components Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special multi-layer coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto components and ruin them. 1. Allow the components to cool completely. 2. Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may also be used, but no residues may remain. 3. Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak Photoflo will help prevent streaking and spotting. 4. Dry with a clean, soft and lint-free cloth or blow dry with compressed air. Fans To maintain adequate cooling it is important that the fans be cleaned of dust and dirt periodically. Use a soft brush, vacuum, or compressed air. Lubrication Use silicone lubricant, Martin P/N 37302003 (500 ml) or P/N 37302004 (200 ml, in applicator bottle). No other lubricant is approved for use. When applying lubricant, always remove excess and do not get oil on other parts. Check the focus mechanism when the head is open and apply a drop of lubricant to the 3 metal slides if movement is rough. Lubricate the rotating-gobo bearings if movement is rough on slow rotation or if they become noisy. Apply a few drops of oil to each bearing from the lamp side of the wheel. 18 MAC 250 and MAC 250+ Replacing fuses Po w e r s u p p ly f u s e s The fuses for each of the 3 low-voltage power supplies are located on the printed circuit board. If one of the circuit board LEDs does not light, one of these fuses may be blown. 1. Disconnect the fixture from AC power. Remove the 2 Philips screws from the plastic cover on the arm opposite the side with the visible motor and pull off the cover. 2. Locate and replace the defective fuse with one of the same rating. The fuses are shown on the PCB layout diagram; their values are listed on page 27. 3. Replace the cover before applying power. Main fuse The main fuse holder is built in to the mains input socket. Never replace the fuse with one of a different rating! 1. Unplug the mains cable from the input socket. 2. Pry open the fuse holder and remove the fuse. 3. Replace the fuse with one of the same type and rating. The fuse rating is listed on serial number label. 4. Close the fuse holder and replace the mains cable. Changing the XLR pin-out The signal polarity of pins 2 and 3 on the XLR connectors can be reversed, allowing the fixture to be connected directly to Martin devices wired with pin 3 cold (-). Optionally, a phase-reversing cable may be used. 1. Disconnect the fixture from AC power. Remove the 2 Philips screws from the plastic cover on the arm opposite the side with the visible motor and pull off the cover. PL234 PL233 PL234 PL233 Martin pin-out DMX pin-out (default) Figure 10: XLR jumpers 2. Position the jumpers on PL 233 and PL 234 for the desired XLR pin-out as shown. 3. Replace the cover before applying power. Updating software The MAC 250 and MAC 250+ operate with the same software. Updates are available from your Martin dealer and the Martin Professional web site. Please read the update notes included with the software. Note: the software automatically defaults to the correct gobo type setting (P ERS /GT YP) in unmodified fixtures. Normal upload Update software is uploaded to the MAC 250 and MAC 250+ using a Martin uploader such as the MPBB1. The uploader is connected to the fixture just like a controller. Under normal conditions, software can be installed from a remote location - there is no need to set the MAC 250 and MAC 250+ to boot mode. Please refer to the uploader manual for further instructions. Boot mode upload If the data is corrupted during transmission, a check-sum error (C S ER) occurs and after 15 seconds the fixture switches to boot mode (U PLd) and is ready for a boot mode upload as described in the uploader manual. If a software upload is interrupted, the fixture must be turned off for at least 10 seconds before a new upload can be attempted. When powered on, a check-sum error occurs and the fixture goes into boot mode, ready for a second upload attempt. Select boot mode upload on the uploader. If there is no functional software in memory, the fixture must be set to boot mode manually. If the control panel works, select UP Ld from the U TIL menu and confirm when S URE is displayed by pressing [ENTER]. Basic Service 19 If the control panel does not work, boot mode can be engaged by moving jumper PL121 on the main circuit board to pins 1 and 2 as follows. 1. Disconnect the fixture from AC power. Remove the plastic cover from the arm opposite the side with the visible motor. 2. Move jumper PL121 to pins 1 and 2 (hard boot setting). See also the diagram on page 26. PIN 1 È PL121 PIN 1 È PL121 normal setting hard boot setting Figure 11: Hard boot jumper 3. Perform a boot-mode upload as described in the uploader manual. 4. Disconnect the fixture from AC power. Move the hard boot jumper back to the normal setting and replace the cover.
