HD Encoder considerations
When saving configuration presets for Networked VGA Grid, it's recommended that you save both the sources
and the channels configuration groups. This is particularly important if you are using multi-source layouts that
employ local channels as sources.
Additionally, care is needed to make sure that VGA Grid HD Encoders are accessible and not in use by another
VGA Grid Concentrator before applying a configuration preset using those HD Encoders.
Examples:
1. If an applied configuration preset creates a channel that employs a local source but that local source is
not found (e.g. was not part of the configuration preset and is not presently configured on the system),
the no signal image is used for that source.
2. If a configuration preset creates a source that is a local channel, but the channel is not presently
configured and was not part of the configuration preset, the source has no signal.
3. If a configuration preset creates a channel containing an HD Encoder that is currently in use by another
VGA Grid Concentrator, no warning is presented to the user and unexpected behaviour occurs. Neither
VGA Grid Concentrator has full control of the VGA Grid HD Encoder.
4. If a configuration preset creats a channel containing a VGA Grid HD Encoder cannot be found on the
network, no warning is presented to the user. The Concentrator continues to try to find the
HD Encoder, in the same fashion it would if an already configured HD Encoder is disconnected from the
network.
