BASIC PIXEL-MAPPING
Overview
The Mbox software allows mapping of certain functions of Color Kinetics KiNET or Art-Net-controlled fixtures (RGB,
Intensity, CMY, etc.) to each of the pixels in the composite video image. Pixel-mapping data is generated from the
screen image and is output from an available Ethernet port of the Mac computer. It may be necessary to use an Art-
Net to DMX512 converter to change the data into a more suitable protocol if the device intended to be controlled
cannot receive Art-Net directly. KiNET devices will receive that protocol directly over Ethernet. When pixel-mapping,
Mbox retains the normal video output so a video signal can still be sent to a display device. Mbox also provides the
ability to previsualize the pixel-mapping setup on the video monitor.
Using Pixel-Mapping with Different Modes:
+
While in Single Output mode, the entire screen can be mapped.
+
While in Panoramic Wide and Panoramic Dual modes, the entire width of the two screens can be mapped.
+
While in Dual Independent mode, only first screen (Output 1) can be mapped.
When pixel-mapping, it is advisable to use
a second Ethernet port on the Mac to
output the pixel-mapping data. If the Art-
Net input and the pixel-mapping output
share a single Ethernet port, the volume of
network traffic generated by complex pixel-
mapping configurations will affect the
reception of Art-Net control data. If you
want to use two different ports for Art-Net
input and pixel-mapping Art-Net output you
will need to set up the Ethernet ports of
your computer properly. Some knowledge
of IP addressing and subnetting practices is
required.. Network settings can be changed
from the Mac's Network preferences
window.
The following guidelines assume that your
computer's first Ethernet port is set to
receive Art-Net to control Mbox and you are
using a second Ethernet port to output
pixel-mapping data.
+
Art-Net is typically sent to the broadcast destination IP address for the local network being used. For Art-Net this
destination address is usually 2.255.255.255*. Art-Net can also be unicast (sent to one specific IP address). Mbox
Art-Net output can automatically be unicast to ArtPOLL compliant devices.
+
KiNET devices have user-configurable IP addresses, therefore, the computer's Ethernet port will need to be set
up accordingly to use the same subnet. Destination IP addresses for KiNET are always unicast.
+
If your computer uses an overlapping or ambiguous IP/subnet scheme for the two Ethernet ports, then your pixel-
mapping output may not be routed from the correct Ethernet port on your computer resulting in a lack of function.
You must ensure that the two ports have settings that allow Mbox to send the data from the correct port.
+
You must also coordinate the IP/subnet of the pixel-mapping output port with the destination IP address(es) in the
Mbox Pix Map Destination Settings (see
* PRG's Series 400 requires data to be sent to a destination IP address of 10.255.255.255. Which will mean configuring
the Ethernet port for pixel-mapping output to an IP address that uses a value of "10" for the first octet.
