Checking voltage and frequency settings
The RoboScan 812 voltage setting must be within 5% of the AC mains supply. The voltage
setting may be adjusted to local conditions. The frequency (50 or 60 Hz depending on
model), however, must match your supply. Check the settings printed on the label near the
mains input. See page 13 to change the voltage setting if necessary.
Releasing the Pan/Tilt Lock
The pan/tilt assembly (9) floats in a special rubber mount to reduce noise when operating
the pan and tilt motors. In order to protect the pan/tilt assembly from damage during shipment, it is secured with two plastic straps and a locking thumbscrew. These must be
removed before using the RoboScan!
It is strongly recommended that the pan/tilt assembly be locked for transportation by replacing the thumbscrew in position A over the pan/tilt assembly.
1.Cut and remove the two plastic straps.
2.Remove the thumbscrew over the pan/tilt assembly and store it in the
threaded hole, labelled B, on the pan/tilt plate.
3.Carefully remove the surface protection foil and war ning notice from the
mirror.
Installing the Mounting Bracket
Use the 11 mm hole in the center of the mounting bracket to fasten a clamp (not included),
or to permanently bolt the fixture in place, with a grade 8.8 (minimum) M10 bolt and lock
nut. For safety, verify that the structure can support at least 10 times the weight of all
installed fixtures, clamps, cables, auxiliary equipment, etc., and always use an approved
means of secondary attachment suc h as a safe ty cable to prevent falls.
The mounting bracket may also be used as a floor stand.
1.Inser t the two black plastic hand wheels into the bracket holes.
2.Place a plastic spacer on each hand wheel, between the bracket and the
casing, and screw the hand wheels into the fixture.
3.Turn or tilt the RoboScan to the desired position and tighten the hand
wheels.

Setup for Controller Operation
Connect the Serial Link
The RoboScan 812 may be used with DMX and Martin protocol controllers. The RoboScan
812’s XLR connections are configured for Martin protocol controllers such as the 3032.
When connecting a RoboScan 812 to any DMX-standard device, you must swap pins 2 and
3 with a phase-reversing cable.
1.Connect the controller’s data output to the RoboScan 812’s input (2). If using
a Martin-standard controller, use a direct 3-pin to 3-pin cable such as the one
provided. If using a DMX controller, use a phase-reversing cable, either 3-pin
to 3-pin, or 5-pin to 3-pin, depending on the output of the controller.
2.Continue the link: connect the output (1) of the fixture closest to the controller to the input of the next fixture. Use a direct cable when connecting
same-standard fixtures. Use a phase-reversing cable only when connecting a DMX-standard fixture to a Martin fixture with pin 2 hot. Up to 32 fixtures may be connected on a serial link.
3.Insert a male 120 Ω XLR ter mination plug in the output of the last fixture
on the link. The termination plug is simply a 3-pin male XLR plug with a
120 Ω resistor soldered between pins 2 and 3. The termination plug isrequired for error-free communication.

Set the Address
When using the RoboScan 812 with a controller, you must set the DIP-switch (3) to the start
channel, also known as the address, which is the first channel the controller uses to send
instructions to the RoboScan 812.
For independent control, each fixture must have its own address and control channels. Two
or more RoboScan 812s may have the same address; however, they will receive the same
instructions and behave identically.
7Installation
Page 8
Martin mode: The RoboScan 812 uses 1 channel to communicate with the controller. The
address may be any channel between 1 and 32.
DMX mode: The RoboScan 812 may be operated in tracking or vector mode; see the DMX
protocol for details. It uses 5 consecutive DMX channels in tracking mode and 7 consecutive DMX channels in vector mode. The factory default is tracking mode. The address may
be any channel up to 508 within the controller’s range (506 if 7 channels are used).
Example: 4 RoboScans using tracking mode (5 channels) may be addressed as follows:
12345678910111213141516171819
812 No. 1
Address: 1
812 No. 2
Address: 6
812 No. 3
Address: 11
812 No. 4
Address: 16
20
Use the following procedure to set a Martin or DMX address.
1.Select an available address within the controlle r’s range.
2.Look up the DIP-switch setting on page 19. You can also calculate it by
subtracting pin values until the total of the values equals the address.
Start with the highest pin value that can be subtracted and work down
until there is no remainder. The table below shows the pin values.
3.Set the DIP-switch (3) by flipping ON the pins found in step 2.

OPERATION
Stand-Alone Operation
The RoboScan 812 may be operated without a controller in stand-alone mode. In this mode,
the fixture performs a random sequence that is triggered by the beat of the music or automatically at a set speed. The DIP-switch must be set to th e desired stand-alone mode before
applying power. Settings for the different modes are shown below.
1.With the fixture powered off, set the DIP-switch (3) for the desired mode.
Pins not listed must be switched off.
2.Apply power to the RoboScan 812 to run the sequence.

Controller Operation
Getting Started
The RoboScan 812 may be used with DMX-512 and Martin protocol controllers; it automatically determines which protocol is in use. Protocol auto-detection can be reactivated if
necessary by switching on all ten DIP-switches and then resetting the address.
1.Connect the RoboScan 812 to the controller and set the address.
2.Switch on and configure the controller.
3.Apply power to the RoboScan. After a short reset procedure it will
respond to the controller.

Controllable Effects
Lamp
After switching on the RoboScan 812, the lamp remains off until a “lamp on” command is
sent from the controller. If using a Martin protocol controller, the lamp may also be turned
off via the controller. This feature is not implemented in the DMX protocol - to turn off the
lamp you must power off the fixture.
It's important to note that the lamp is a cold restrike type: it must be cold before striking is
possible. The lamp must cool for approximately 5 minutes before it can be turned on again.
Pan/Tilt
The moving mirror allows you to pan the beam 175° and tilt it 83°. Movement speed may
be adjusted with the controller fade time (DMX tracking mode and Martin controllers) or
on a separate channel (DMX vector mode).
Color Wheel
The RoboScan 812 has 13 positions on the color wheel: 11 with saturated dichroic colors,
open white, and blackout. The wheel can be positioned between 2 colors to split the beam.
The speed of the color and gobo wheels may be adjusted with the controller fade time
(DMX tracking mode and Martin controllers) or on a separate channel (DMX vector mode).
Selecting color strobe causes the color wheel to change between any 2 adjacent colors or
between white and black. The strobe speed is variable.
Gobos
The RoboScan 812 has 11 gobos on the gobo wheel plus open and blackout. Selecting gobo
strobe causes the gobo wheel to change between any 2 adjacent gobos or between full open
and black. The strobe speed is variable.
Random Sequence
The RoboScan 812 may be set to perform a preprogrammed sequence with automatic or
music trigger.
Focus
Focus may be adjusted manually from 1 meter to infinity by turning the threaded lens bar rel
(7). Screwing the lens in increases the focus distance; screwing it out decreases the distance
at which the image is focused.

Adjusting the Lamp
The RoboScan 812 comes fully adjusted from the factory, however, readjustment of the
lamp may improve performance. The lamp is adjusted by turning the 3 screws (11) on the
lamp access plate (12). Turning these clockwise pulls the lamp back towards the rear and
vice versa. Keep adjustments small to avoid pulling the lamp so far off center that it hits the
reflector.
1.Set up the RoboScan 812 so th at you can access the lamp-access plate (12)
and, if adjusting the lamp without a controller, the DIP-switch (3).
2.With controller: Turn on the RoboScan 812 and allow the lamp to warm
up for 5 minutes. From the controller, select white light with the open
gobo and position the beam on a flat, white surface. Focus the beam.
Without controller: Flip DIP-switch pins 1, 5 and 10 on. Flip all other
pins off. Apply power to the RoboScan 812. After it has reset, the fixture
produces a white light with an open gobo for adjustment purposes. Wait
approximately 5 minutes for the lamp to reach full brightness. Position
the fixture and/or mirror so the light shines on a flat, white surface and
focus the beam.
3.If there is an off-center “hot spot,” the lamp is not centered in the reflector. Pull the hot spot into the center of the field with small adjustments of
one or more of the screws (11). Note: the Martin Metal Halide lamp is
nearly as large as the reflector opening - very little side to side adjustment is possible or necessary.
4.If the light is significantly brighter in the center of the field than it is at the
edge, the lamp is too far forward in the reflector. Pull the lamp in by turning all three screws clockwise 1/4-turn at a time until the light is evenly
distributed.
5.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. “Push” the lamp out
by turning the screws counterclockwise 1/4-turn at a time until the light is
bright and evenly distributed.
6.If you have made large sideways adjustments, disconnect the fixture from
AC power, allow it to cool, and remove the lamp assembly to ensure that
the lamp is still placed squarely in the socket.

DMX 512 PROTOCOL
The RoboScan 812 supports tracking and vector mode. In tracking mode, speed is determined by the controller’s fade time. In vector mode, speed is determined by a value programmed on a separate DMX channel. For smooth movement in vector mode, the
controller’s fade time must be set to 0, i.e., the position must bump fr o m the current value to
the next. If the RoboScan 812 is set to run vector mode, tracking mode can be enabled by
