Primary and Secondary DVEs
There are two types of external DVEs that can be connected to a Synergy switcher:
• Primary External DVE
Only one primary external DVE (either single or multi-channel) can be connected to a
Synergy switcher at a time. The connection includes:
~ Video and Key signal routed from the Aux Bus outputs of the Synergy switcher to
the external DVE.
~ Video and key routed from the external DVE back to the Synergy switcher.
~ Serial communication can be RS-422 or RS-232, RS-422 serial control from the
Synergy switcher to the external DVE.
Serial control allows you to run the external DVE using the DVE Send feature, as well
as using the Custom Control buttons.
• Secondary External DVE
You can connect as many secondary external DVEs (either single or multi-channel) as
desired to a Synergy switcher. The only limit is the number of available Aux Buses from
which to route signals. The connection includes:
~ Video and Key signals routed from the Aux Bus outputs to the external DVE.
~ Video and Key signals routed from the external DVE back to the Synergy switcher.
Note that a secondary external DVE cannot be controlled using commands. Therefore,
in this configuration, the power of each secondary external DVE is available (just like
the primary external DVE), with the restriction that the secondary DVE
must be
controlled from its own local control panel or via GPI output pulses from the Synergy
switcher. Refer to the section “
GPI Output Connections ” on page 13-10 for details.
