10. NOTES ABOUT CONNECTION AND OPERATION
FOR DVE INTEGRATION
10.1 PRESETTINGS
Utilize the ”DVE key” and ”DVE fill” outputs of the switcher to feed the DVE.
If the DVE does not have a ”flying key” channel, only the ”fill” connection is needed.
Feed the DVE key and fill outputs as inputs into the switcher.
Memorize the selected inputs.
Connect DVE and switcher via their remote ports (in most cases RS422) with a 1:1
D-type cable, 9-pin.
The appropriate DD switcher ports are the ports 1, 2, 3: any port can be selected.
Exception: A53D only on port 1 because of the RS232 interface.
Select the appropriate DVE protocol (for the port, the DVE is connected to) within
the setup of the switcher (the DVE type is indicated). A general DVE type is ”VTR
protocol”.
Select – within the setup of the switcher – to which the DVE fill and key signal is
attached.
This is needed for the FXLoop operation.
10.2 PREPARATION
Recall or generate DVE sequences, that are supposed to be controlled by the
switcher.
Load them into the snapshot registers of the DVE.
With most DVEs, a scaling of the DVE sequence is needed (in order to harmonize
the move of the switcher fader arm with the start and the end of the DVE sequence).
Scale the sequence to 30 seconds.
It gives a sufficient fader resolution to avoid jerky effect movement.
(30 s x 25 frames = 750 iteration values).
Set the DVE to remote control.
