PixLite E4-S Mk3 User Manual V20220819
The controller(s) can be integrated straight into any pre-existing LAN such as your
media, home or office network, the above diagrams are only provided as examples.
6.2 - IGMP Snooping
Installations using multicast sACN will benefit from the use of IGMP Snooping enabled
network equipment when there are more multicast universes on the network than
any one PixLite is using. If there are more than 24 universes of multicast sACN on the
network then IGMP Snooping is mandatory.
Note
: "E" Series devices are not equipped with a Universe Data Hardware Firewall,
which many other PixLite Mk3 devices have. This feature removes the need for IGMP
Snooping. This means that operation of the PixLite E4-S Mk3 in the situation described
above will require IGMP Snooping, as there is no hardware firewall in place.
6.3 - IP Addressing
6.3.1 - DHCP
Routers typically have an internal DHCP server, which means they can assign an IP
address to a connected device, if requested.
DHCP is always enabled by default on this device, so it can immediately connect to
any existing network with a router / DHCP Server. If the controller is in DHCP mode and
is not assigned an IP address by a DHCP server, it will assign itself an IP address with
Automatic IP Addressing, as explained in
below.
6.3.2 - AutoIP
When this device has DHCP enabled (factory default), there is also functionality for it
to be operational on networks without a DHCP server, via the AutoIP mechanism.
When no DHCP address is being offered to this device it will generate a random IP
address in the range of 169.254.X.Y that does not conflict with any other devices on
the network. The benefit of AutoIP is that communication can happen between the
device and any other compatible network device, without the need for a DHCP server
or pre-configured Static IP addressing.
