Destination IP Addressing
The configuration of the Ethernet interface 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 interface on your
computer they will be output from. (Refer to
"Appendix A. Networking For Mbox" on page 102 for
more detailed information.)
If you have two Ethernet ports on your computer,
recommended practice is to receive Art-Net or sACN
to control Mbox on one interface and to output pixel
mapping data from the other interface. Therefore the
two ports must be on separate subnets to ensure
that Mbox can determine which interface to use.
If a broadcast IP address is used for Art-Net
destinations, 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 can
unicast universes to the specific IP Address for those devices. Note: If more than one device responds to an ArtPOLL
stating that they require a universe of data, then that universe will be broadcast instead of being unicast.
CAUTION! While most Art-Net devices use an IP address of 2.#.#.# and subnet mask of 255.0.0.0. some devices can
be configured to use other IP addresses. Don't assume that setting the Mbox’s IP address and subnet mask to a
2.#.#.#/8 scheme 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 ArtPOLL compliant and non-compliant devices, where these devices are required to receive the
same universe(s), the default action of Mbox will be to unicast the data to the ArtPOLL- compliant devices only. At this
point the non-compliant devices will not receive the Art-Net. In such cases, you will need to disable ArtPOLL by
checking the "ArtPOLL Disable" checkbox on the Setup tab and then restarting the Mbox application.
Suggested Ethernet Setup for Art-Net Output:
+ Interface 1 (receiving Art-Net for control) - IP=2.1.0.123 Subnet Mask=255.255.0.0
+ Interface 2 (sending pixel mapping Art-Net) - IP=2.0.0.123 Subnet Mask = 255.0.0.0
+ Pixel-map destination IP address for default destination - 2.255.255.255 or Ethernet 2
Example Ethernet Setup for sACN Output (to ETC Net3 device, using ETC’s suggested addressing for media servers):
+ Interface 1 (receiving Art-Net for control) - IP=2.0.0.123 Subnet Mask=255.0.0.0
+ Interface 2 (sending pixel mapping sACN) - IP=10.101.130.123 Subnet Mask = 255.255.0.0
+ Pixel-map destination IP address for default sACN destination - 10.101.255.255 or Ethernet 2
Example Ethernet Setup for KiNET Output:
+ Interface 1 (receiving Art-Net for control) - IP=2.0.0.123 Subnet Mask=255.0.0.0
+ Interface 2 (sending pixel mapping KiNET) - IP=10.0.0.123 Subnet Mask = 255.0.0.0
+ Pixel-map destination IP addresses are all unicast
The above setups ensure that the computer can receive Art-Net on the first interface, and that it will also send pixel
mapping output from the second interface. The key factors being the use of the correct IP address for the interface in
question, and the “coordination” between the subnet mask of the second interface and the destination broadcast IP
address for the pixel mapping data. These are only a few of many possible IP address/subnet mask configurations
