Introduction
Rosco’s I-Cue Mirror is a motorized mirror attachment that provides precise,
DMX controlled direction to the light beam from an ellipsoidal reflector spotlight.
It can be used to turn stationary light into a "moving light" by moving the beam around
up and down, left and right. The I-Cue can also be used to direct the light beam to a
specific spot. Since the I-Cue’s DMX control can re-direct the beam to meet the
needs of dozens of light cues, the number of instruments needed is minimized.
The I-Cue Mirror is lightweight, compact and quiet enough to use in any production setting. With the ability to integrate with color scrollers, it is possible to produce
both motion and color changing from one ellipsoidal fixture. The I-Cue Mirror offers
lighting designers a precision of movement usually found in high-end, high priced
Moving Lights.
The unit is designed to work with the ETC Source Four, Altman Shakespeare,
Strand SL, and Selecon Pacific series fixtures.

The I-Cue does not interfere with the positioning or focusing of the light fixture.
O p t i mum operational chara c t e ristics are achieved when the device is used on fixtures
with a beam angle of 36 degrees or less.
The Pan range is up to 230 degrees with the Tilt range up to 57.3 degr e e s. T h e
light is reflected to the desired direction by a large 6”x 7 ”ellipsoidal glass mirror and
the unit is suitable for operation in any position.
The unit comes in a basic configuration with universal mounting brackets for
ellipsoidal spotlight fixtures. Modular power supplies and accessory cable are also
available for the units.
Control And Power Requirements
The device requires 24-volt DC external power supply and operates on two or
four channels of DMX 512 to control the movement of the mirror. Power and DMX
signals are transmitted to the unit via a four conductor XLR scroller cable.
In the two-channel mode, one channel controls the pan and the other tilt with
8 -bit resolution. In this mode the pan range is 230 degrees with 0.9 degrees of resolution and the tilt range is 57.3 degrees with 0.225-degree resolution.
In the four-channel mode the channels are respective l y, Pan coarse, Pan fine, T i l t
c o a r s e, and Tilt fine with 16-bit resolution. In this mode the pan range resolution is 0.228
d e grees and the tilt range resolution is 0.028. The user can choose 8 or 16-bit opera t i n g
mode by means of Dipswitch #1.(See Addressing and Modes of Operation section.)
The scroller cable power pair is 14AWG and the data pair is 22AW G . T h e
c o nnectors are four pins XLR with the fo l l owing Pin-out. Pin 1 is 0 volts DC and pin
4 is +24 volts DC and pin 2 is DMX (-) with pin 3 being DMX (+). Care should be
t a ken to confirm that the output of the power supply used confo rm s
to the above as some scroller power supply manu facturers use
r everse polarity in their units. The device draws 0.7 amps at 24 volts.
Unpacking Of The Unit
The unit is shipped in a specially constructed shipping carton to provide protection
to the unit. Carefully open the carton and remove the device by grasping the support
a rm in the middle and lifting the unit ve rtically out of the cart o n . N ext, carefully remove
the ru bber restraint band used to stabilize the mirror unit during shipment.
The front light shield had been designed so that it can act as a shipping support and
must be repositioned before using the device as a moving mirror. Loosen the two M4
wing screws on the front of the unit and reposition the light shield by moving the shield
d ow n ward to the position necessary to prevent light leaks depending on the beam angle
and focusing.
