minimal. Consult the vendor or documentation of your network switches for further
information.
Another use case for the second Ethernet port is to connect a third-party network
device, like a laptop or a server, to the end of a chain of PixLite Mk3 devices. A PixLite
device with only a single Ethernet port could also be connected to the end of a chain
of PixLite Mk3 devices.
6.4 - IPAddressing
6.4.1 - 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 Section 6.4.2 below.
6.4.2 - 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.
This then means that connecting a PixLite A4-S Mk3 directly to a PC typically does not
require any IP address configuration - communication will be possible because both
devices would generate their own valid AutoIP.
While the device has an AutoIP address in use, it continues searching for a DHCP
address in the background. If one becomes available, it will switch to the DHCP
address instead of the AutoIP.
