106 MBOX ® MEDIA SERVER USER MANUAL
BASIC PIXEL-MAPPING
Overview
The MBOX software allows mapping of certain functions of Art-Net-controlled fixtures (RGB, Intensity, CMY, etc.) to
each of the pixels in the composite video image. Art-Net 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.
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 Art-Net data. If both Art-Net
input and 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
Apple menu or 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 Designer
and you are using a second Ethernet port to
output pixel-mapping Art-Net.
+ 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 Designer's Art-Net output
will automatically be unicast to ArtPoll compliant devices.
+ If your computer uses an overlapping or ambiguous IP/subnet scheme for the two Ethernet ports, then your pixel-
mapping Art-Net 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 Designer 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 in MBOX
DesignerS's Pix Map Connection Settings window (see
page 109 ).
* PRG's Series400 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.
