The number of pixels/string sets the number of
dimmers (channels) on the DMX networks. Each
pixel is three dimmers. You should not set the
number of pixels to less than 40 (120 channels or
dimmers) because some older DMX fixtures may
have problems with the short DMX messages. The
maximum number of pixels is 170 (510 dimmers).
In the Sequence Editor, you can use the “Insert
device” feature to insert an iDMX1000 for one or
more of the 4 DMX universes created by a
Pixie4DMX. This will create a iDMX1000 with the
number of channels (dimmers) you specify. You can
combine some of these channels into RGB pixels if
that is appropriate for the DMX fixtures on your
network(s). When you manipulate a pixel or channel
with Sequence Editor, SuperStar or Pixel Editor
commands, these commands will be converted to
intensities and output on the DMX universes.
Pixie4DMX High Speed USB adapter
The Pixie4DMX includes a USB interface so that it
can be directly connected to a PC. The USB
interface is exactly the same as a LOR USB adapter.
It runs up to 1Mbps and you can daisy chain other
LOR controllers on this network by using the
Pixie4DMX’s RJ45 LOR network connectors.
Pixie4DMX on Regular LOR Networks
Some DMX fixtures require that you send certain
intensity values to dimmers to control operation of
the fixture. See the
LOR intensities to DMX
Intensities
table for the mapping of LOR 0-100%
intensities to DMX 0-255 intensities.

Hardware Configuration
Assigning a Unit ID
Second generation Pixies have a DIP switch with 8
positions. This is used to set the unit ID. If all DIP
switches are set to ‘off’, then the unit ID as set by
the Hardware Utility will be used (see below). Refer
to the
DIP Switch Address
section for the mapping
of your desired LOR address to DIP switch settings.
First generation Pixies do not have unit ID switches,
so the Unit ID must be assigned with the Hardware
Utility as follows:
If you have not installed the Light O Rama Windows
Showtime Software, do it now. The controller must
be powered by a 5-12vdc power supply (Pixie4DMX
requires 12vdc). You can use one of LOR’s USB
RS485 adapters or you can plug a Pixie4DMX
directly into a USB port. See the
Connecting the
Pixie to a PC
section for more information.
Power up the controller. The Status LED will blink
about twice/second. This means that the controller
has booted and is waiting for the PC to talk to it.
