CONTROL PORTS AND PROTOCOLS - continued
GVG 4000
This protocol allows an editor capable of controlling a GVG 3000 or 4000 switcher to drive the P/P
bus of the Switcher. Learn and Recall of DMEMs (E-MEMS) to and from the hard disk in the
switcher is supported. The protocol also supports transfer of DMEMS and Timelines to and from
the editor, and running of Timelines from the editor. Editors capable of driving the GVG 2200
series should also work with this interface
The P/P is driven by the M/E-1 part of the protocol and the DSK section is driven by the DSK-1 part
of the protocol.
Controlling the PVW bus from the Editor controls the switcher’s PVW 1 bus.
Controlling AUX 1 from the Editor controls the switcher’s PVW 2 bus.
Controlling AUX busses 2 to 9 from the Editor controls the switcher’sAUX 1 to 4 busses.
When setting areas of the switcher to Learn/Recall/Transfer DMEMs or run Timelines, the
protocol’s BKGD area will drive the switcher’s SOURCES DMEM/Timeline Enable, and the
protocol’s MISC area will drive the switcher’s GLOBAL DMEM/Timeline Enable.
