Setup
Use the setup tab to configure network settings for DeckLink IP capture and playback cards
such as DeckLink IP HD, DeckLink IP HD Optical and DeckLink IP/SDI HD.
Network Settings
DeckLink IP cards can connect to the
network using a static IP address or by
using DHCP.
DHCP will automatically set an IP
address and connect to the network
without the need to change any
settings. The dynamic host configuration
protocol, or DHCP, is a service on
network servers and routers that
automatically finds your DeckLink IP
card and assigns an IP address. DHCP
makes it easy to connect equipment
via Ethernet and make sure that IP
addresses do not conflict with each
other. Most computers and network
switches support DHCP.
Select static IP if you want to set the IP
address yourself. Simply set the protocol
setting to 'static IP' and change the IP
settings manually. A static IP address
is one that won't change even if your
computer is rebooted. Using a static IP address might be necessary if you are connecting to a
corporate network.
If you have a network administrator, it's possible your network might have custom IP addresses
for all the equipment connected to it. It's best to check with your network administrator if they
are managing your computers and network in your company.
Connecting to a Network
When plugging into your network, make sure you connect via a Cat 6 network cable or optical
fiber depending on which DeckLink IP model you are using. The 'ST2110' specification relies on
multicast data to efficiently distribute video, audio and ancillary data.
We strongly recommend the use of a dedicated PTP grand master clock device in a network
configured to support the IGMP version 3 multicast data protocol.
2110 Multicast Output
This setting is similar to an IP address and lets other DeckLink IP cards and SMPTE 2110 IP
equipment identify the stream on your network. Each stream from your DeckLink card requires
its own multicast output address and you can assign one for each by selecting them from the
setup utility home screen.
It is important the address is unique and not shared by other 2110 IP equipment on your
network. Consult your IT administrator for guidance on which address to use if you are unsure.
The numbers in each field should be set within the following limits:
224.0.0.0 to 239.255.255.255.
For example, 224.24.29.73
