INTRODUCTION
Thank you for selecting the Martin RoboScan Pro 918. This scanner, with its highly efficient optical and thermal
design, provides quiet operation and crisp, bright output in a compact, easy-to-handle package.
This manual covers all models of the RoboScan Pro 918 and describes the features found in CPU software version 1.4.
The latest Pro 918 information and software is available from the Martin Professional web site at http://
www.martin.dk.
SAFETY PRECAUTIONS
The RoboScan Pro 918 is for professional use only. It presents potential risks due to electrical shock, heat and ultra-
violet radiation burns, lamp explosion, falls, high-intensity light, and fire. A thorough understanding of the dangers,
genuine concern for safety, and attention to detail are required to prevent accidents. Read this manual before power-
ing or installing the fixture, follow the safety precautions listed below and observe the warnings in this manual
and printed on the fixture, and always double check the safety conditions. If you have questions about how to
operate the Pro 918, please contact your Martin dealer for assistance.
•$OZD\VýGisconnect the fixture from AC power before:
- Changing the transformer or ballast settings
- Installing or removing the lamp
- Checking or replacing fuses
- Removing any cover or part
• Replace the lamp before usage exceeds the maximum rated service life or if the lamp becomes defective or worn out.
Allow the fixture to cool for 15 minutes before replacing the lamp.
• Keep all combustible materials (for example fabric, wood, paper) at least 0.5 meters (20 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.
• The covers get very hot under normal operation: to avoid burns, locate the fixture where it cannot be accidentally
touched or bumped, and allow the fixture to cool before servicing.
• Do not illuminate surfaces within 1 meter of the fixture.
• Never place filters or other materials over the lens or mirror.
• Do not operate the fixture if the ambient temperature (Ta) exceeds 40° C (104° F).
• Do not look directly into the light from a close distance.
• 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.

SETUP
This section describes the steps required to prepare the RoboScan Pro 918 for operation.
UNPACKING
The RoboScan Pro 918 package includes:
• 1 5-meter, 3-pin shielded XLR control cable
• 1 3-meter, 3-wire IEC power cable (EU version only)
• 1 user manual
• 9 extra rotating gobos
• 1 spare rotating-gobo spring
The packing materials are carefully designed to protect the fixture during shipment - always use them or a custom
flight case to transport the fixture.
INSTALLING OR CHANGING THE LAMP
The RoboScan Pro 918 is designed to work with the Philips MSR-575/2, Philips MSD-575, or the Osram HSR-575/2
discharge lamp. Installing any other lamp may damage the fixture. The lamp holder is pre-adjusted at the factory; pre-
cise alignment may be necessary due to slight variations between lamps. The procedure is described on page 21.
WARNING!
Disconnect the fixture from AC power before proceeding. Always wear safety
goggles to protect your eyes and allow a hot lamp to cool for at least
15 minutes before removing it from the fixture.
1. The RoboScan Pro 918 must be cool and isolated from AC power. Remove the 2 screws (A) securing the
lamp assembly to the back plate. Gently pull out the assembly.
2. If changing the lamp, remove the old lamp from the socket.
3. Holding the new lamp by its ceramic base (do not touch the glass), insert it firmly and squarely into the lamp
socket. Clean the glass bulb with the cloth supplied with the lamp, particularly if your fingers touch the glass.
A clean, lint-free cloth wetted with alcohol may also be used.
4. Reinsert the lamp assembly and replace the screws.
5. Before turning the lamp on, reset the RLAH and RLST counters. See “Readouts” on page 11.

Setup
POWERING THE FIXTURE
WARNING!
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. These settings are printed on the
serial number label next to the control panel. If the settings do not match the supply, then the ballast and
transformer must be rewired as described under “Changing voltage and frequency settings” on page 18.
2. You may need to install a cord cap that fits your supply on the power cable. Following the manufacturer’s
instructions, connect the wires as shown below. Note: 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.
3. Verify that the supply cable is undamaged and rated for the current requirements of all connected devices.
Do not connect the Pro 918 to a dimmer system: doing so will damage the fixture.
INSTALLATIONý
Using the mounting bracket as a floor stand
WARNING
When standing the fixture with the lamp end down, the end panel must be a min-
imum of 75 mm (3 in) above the floor to provide adequate circulation.
1. If standing the fixture with the mirror end up, loosen the mounting bracket and align the pointer with the last
index line: the bracket shall not be placed any farther from the end. Tighten the clamps securely. Loosen the
swivel locks and set the angle to the extreme position, marked as “-”. Tighten both swivel locks.
2. If standing the fixture with the mirror down, slide the mounting bracket to the mirror end and set the pointer
near the last index line; the exact position is not critical. Tighten the clamps securely. Loosen the swivel
locks and set the angle in between the 60° and 75° marks. Tighten both swivel locks.
3. Stand the fixture on a stable platform away from publicly trafficked areas. Verify that the fixture is stable;
adjust the bracket if necessary.

Rigging
The mounting bracket allows the Pro 918 to be rigged at any angle. The figure below shows the index position of the
balance point at different angles. Balancing the fixture makes it more stable and easier to work with, but it can be hung
out of balance if necessary.
WARNING!
Attach an approved safety cable to the eye hook.
1. Loosen the clamps (B) on each side of the mounting bracket, slide the
bracket to the approximate position, and partially tighten the clamps.
2. Loosen the swivel locks (E) and tilt the bracket to the desired angle.
Partially tighten the locks.
3. Bolt rigging clamps that can bear at least 10times the weight of the fix-
ture to the mounting bracket. 1 clamp may be bolted to the center hole
or 2 clamps may be bolted to the 2 outside holes (C). See page 31 for
clamps available from Martin.
4. Verify that the structure can bear at least 10 times the weight of all
installed fixtures, clamps, cables, auxiliary equipment, etc.
5. Block access below the work area. Working from a stable platform,
place the fixture on the rigging.
6. Install a safety wire that can bear at least 10 times the weight of the fix-
ture. Use the eye hook (D) to fasten the safety wire to the fixture.
Never
use the carrying handles or mounting bracket for secondary attach-
ment.
7. Tighten the rigging clamp(s) securely to the structure.
8. Fine-tune the position and the fully tighten the slide clamps and swivel
locks.
CONNECTING THE SERIAL LINK
The default pin-out is compatible with DMX-512.
The Pro 918’s 3-pin data sockets are configured for DMX controllers,i.e., pin 1 to shield, pin 2 to cold (-) and pin 3 to
hot (+). As many devices have 5-pin connectors or 3-pin connectors with reversed polarity on pins 2 and 3, adaptor
cables may be required.
1. Connect the controller’s data output to the RoboScan Pro 918’s data input. For a
• DMX controller with 5-pin output: use a cable with 5-pin male and 3-pin female connectors such as P/N 11820005.
Pins 4 and 5 are not used.
• DMX controller with 3-pin output: use a normal cable with 3-pin male and female connectors.
• Martin RS-485 Protocol controller: use a phase-reversing cable, such as P/N 11820006, with 3-pin male and female
connectors, or reconfigure the data sockets as described on page 19.

Setup
2. Continue the link: connect the output of the fixture closest to the controller to the input of the next fixture.
Use a phase-reversing cable when connecting a DMX-standard (pin 3 +) device to a Martin-standard (pin 3
-) device.
3. Insert a male 120
Ω
XLR termination plug in the output of the last fixture on the link.
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 4-
Channel 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.
