Appendix: K2 Edge IOs
18.1 Tiles
De K2 Edge contains 8 bidirectional SDI-ports. One video format can be configured per tile. IO1 is
always configured as input and IO2 as output to be able to use the bypass relay. A number of presets
have been defined for the K2 Edge. These presets are selected via the IP Manager.
IOs and tiles.
18.2 Bypass
Ports IO1 (input) and IO2 (output) can be internally connected to bypass a Channel. When set to
bypass, the signal of the main Channel is ignored, and instead the feed received at IO1 is made
available at IO2. Bypass is enabled via the IP Manager.
18.3 Master and Slaves
To make a Channel's signal available on several SDI-outputs, one or more of the IO-ports can be
configured to become slave outputs. By default, the signal provided by a slave output is an exact copy
of the master output signal. A slave output uses the properties of the master Output it refers to, and
thus cannot introduce another broadcast format for the same Channel.
18.4 Genlock
If enabled, the SDI-output synchronizes to the frame rhythm of the genlock (blackburst) signal
connected to the blackburst BNC-socket on the back of the server. If disabled, or when no genlock
signal can be detected, the output will synchronize to an internal clock. Genlock can only be set for
master outputs.
