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 digital display will light when
power is present. (Figure 2)
Immediately after receiving power, the DMX Iris Unit may go through a
homing cycle, ending in a full open or closed position of the iris.
DMX Control
To operate the DMX Iris from a DMX lighting console, you will need to
connect a 5-pin DMX cable to the unit. The DMX Iris is equipped with two
DMX ports,
IN
and
OUT
. (Figure 1) Connect the 5-pin DMX cable coming
from your lighting console to the
IN
port. If your DMX chain continues
beyond the DMX Iris, plug the next cable section into the
OUT
port. The
DMX Iris may require an external DMX terminator to be installed in the
OUT
port if used at the end of your DMX chain.
If no DMX signal is present, the digital display will indicate “LOST” and “512”
in alternating sequence. If a DMX signal is present, the display will indicate
both the operation Mode and the current DMX address of the Iris. (Figure 2)
In this example, the DMX Iris is set to Mode 2 and DMX Address 001.
Configuring the DMX Iris
The DMX Iris can be operated in one of four different modes, depending on
the features and options desired. Modes 1 and 2 use one channel of DMX to
control the DMX Iris. Modes 3 and 4 require two channels of DMX.
