Go back to the Pixel Map tab and adjust the slider for the DMX Ghosting control. Reduce the level of this control to
about 30% and then return to the Window view. Now, the patched fixture view will display patched fixtures at full
brightness and unpatched pixels at a reduced intensity. This enables you to better visualize the result of your setup
(both context sizing and fixture placement) without needing to set up the rest of your equipment.
As noted on page 116 , the configuration of the Ethernet port on your computer and the destination IP address on the
Destinations tab of the fixture table should be coordinated. Destination IP addresses determine both how the
outgoing pixel-mapping packets are addressed, but also which Ethernet port on your computer they will be output
from.
If you have two Ethernet ports on your computer, recommended practice is to receive Art-Net to control Mbox on one
port and to output pixel-mapping data from the other port. Therefore the two ports must be on separate subnets to
ensure that Mbox can determine which port to use.
If a broadcast IP address is used for Art-Net Dests, Mbox will broadcast pixel map Art-Net using that broadcast
address. But in cases where the computer is connected to ArtPOLL compliant devices (e.g., Artistic Licence Ether-
Lynx) Mbox will unicast selected universes to the specific IP Address for those devices. If more than one device
responds stating that they require a universe of data, then that universe will be broadcast instead of being unicast.
+ Most Art-Net devices use an IP address of 2.#.#.# and subnet mask of 255.0.0.0. However some devices can be
configured to use other IP addresses, don't assume that your IP address and subnet mask are correct, always
check.
+ Some Art-Net devices do not respond to ArtPOLL requests and should always
receive broadcast data. If you are using a system with both ArtPOLL compliant
and non-compliant devices where these devices are required to receive the
same data, the default action of Mbox will be to unicast the data to the ArtPOLL-
compliant devices. At which point the non-compliant devices will not receive the
Art-Net. In such cases, you will need to disable ArtPOLL by checking "ArtPOLL
Disable" the box on the Setup tab and then restarting the Mbox Designer
application.
