Set-Up and Installation

Power Requirements

The Rosco DMX Iris is equipped with an internal, auto-sensing power supply.
It will automatically adjust and accept power input from 100 volts to 240
volts at a frequency range of 50 – 60 hz.

Connect the included IEC power cord by rmly pushing it into the recessed
socket on the DMX Iris. (Figure 1) When using the DMX Iris in regions using

connectors other than a u-ground type, simply replace the connector or
substitute the included IEC cable for one with the appropriate connector
type. Make sure to use an IEC cable with at least 18 gauge conductors.

Plug the connected power cord into a suitable non-dim or mains power
supply. Do not connect the DMX Iris to a dimmer circuit unless the dimmer
has been preset into a non-dim mode. The green LED indicator light will
illuminate when power is present. (Figure 2)

Immediately after receiving power, the DMX Iris Unit will go through a
homing cycle. For approximately 10 seconds. It will revert to its open or
closed position, determined by the Normal Switch.

Pressing the Test Button will cycle the DMX Iris closed and back to open -- or
open and back to closed if the Normal Switch is in the CLOSE position.

DMX Control

If you are using the DMX Iris with DMX control, you will need to connect a
5-pin DMX cable to the unit. It is equipped with (2) DMX ports, input and
out (pass-through). (Figure 1) The DMX Iris may require an external DMX
terminator if used at the end of your DMX chain.

The green LED indicator light will illuminate when a DMX Signal is present.

Setting the DMX Address

The DMX Iris uses one channel of DMX. Use the three rotary pots to set the
desired DMX address, for example 2-0-1 = DMX Address 201. The small arrow
on each rotary switch indicates the setting. (Figure 2)
