If locking to a reference, adjust this setting to time
the video output relative to the reference input.
Connector Mapping for DeckLink Quad 2
If you have a DeckLink Quad 2 installed in your computer, you can input or output SDI signals
over 8 independent mini BNC connectors. This gives you the ability to capture or play back 8
separate video streams, similar to having 8 capture and playback devices in a single product.
This is why your DeckLink Quad 2 appears in Desktop Video Setup as 8 individual DeckLink
Quad devices which makes it easier to configure your inputs and outputs. You can even name
each device so you can keep track of which DeckLink Quad device is being used for a specific
video signal.
SDI connectors can be mapped to each device using the ‘connector mapping’ settings in the
Desktop Video Setup utility, but it’s important to know that specific connectors are dedicated to
specific devices. For example, SDI 1 is dedicated to DeckLink Quad (1), and SDI 2 is dedicated
to DeckLink Quad (1) and DeckLink Quad (5).
If you have a DeckLink Quad 2 installed, the ‘connector mapping’ setting
lets you assign SDI connectors to each DeckLink Quad device.
You can see which SDI connectors are dedicated to each DeckLink Quad device by looking at
the table below, where you can also check the mapping options for them.
Mapping Options
DeckLink Quad Devices Dedicated SDI Connectors
DeckLink Quad (1) SDI 1 and 2 or SDI 1
DeckLink Quad (2) SDI 3 and 4 or SDI 3
DeckLink Quad (3) SDI 5 and 6 or SDI 5
DeckLink Quad (4) SDI 7 and 8 or SDI 7
DeckLink Quad (5) SDI 2 or none
DeckLink Quad (6) SDI 4 or none
DeckLink Quad (7) SDI 6 or none
DeckLink Quad (8) SDI 8 or none
It’s worth mentioning that when configuring an SDI connector for a specific device, it will also
affect the device sharing that connector. For example, if DeckLink Quad (1) is set to use SDI 1
and 2, DeckLink Quad 5 will automatically be set to ‘none’ because its shared SDI connector is
being used. Alternatively, if you select SDI 2 on DeckLink Quad (5), DeckLink Quad (1) will
automatically be set to SDI 1. For this reason, it’s important to note which SDI inputs or outputs
are being used by each device to avoid accidentally interrupting the input or output of
another device.
