Grass Valley VM 3000 System Controllers v.7.4 - Manual (Page 46)

Introduction
1−8 VM 3000 Installation and Operating Manual
GVG Horizon Matrix Control − Allows Jupiter to control GVG Horizon routing switchers with a Horizon C−Bus GPI inter-
face. Each Horizon router uses one serial port pair, or two serial ports, of the VM 3000. Each VM 3000 is limited to one router.
Router sizes are limited by GVG.
Vistek Array Matrix Control − Allows Jupiter to control Vistek Array routing switchers with an RS−422 interface. Each
Vistek router uses one serial port pair, or two serial ports, of the VM 3000. Each VM 3000 is limited to one router. Router
sizes are limited by Vistek.
Utah Scientific Control − Allows Jupiter to control Utah Scientific routing switchers with a Utah PL−320 or UDI−1B inter-
face. Each Utah router uses one serial port pair, or two serial ports, of the VM 3000. Each VM 3000 is limited to one router.
Router sizes are limited by Utah Scientific.
Other serial protocols supported are Microvideo, Nexus, Novotronic, and Sony (PURS)
MACHINE CONTROL
VTRs can be those equipped for basic RS−422 control (such as most late model Philips, Panasonic, and Sony machines) or
full ESbus control (such as the Philips DCR−500). Each VTR using the basic RS−422 control scheme requires one dedicated
port of a VM/SI 3000 system control interface, which is the interface used between RS−422/ESbus devices and the thin net.
ESbus VTRs can be connected in loop−through fashion to a single port of a VM/SI 3000 (ESbus multi−point scheme), or,
to individual ports of the VM/SI 3000 (ESbus single−point scheme). The single−point technique requires more wiring but
has a speed advantage over the multi−point method.
Film scanners and other devices capable of RS−422 control can also be connected to the Jupiter LAN by means of a VM/SI
3000. Additional interfaces, such as the MI 3040 General Purpose / Tally Interface, are available for most parallel−control
machines.
INTEGRATION WITH MASTER CONTROL AND AUTOMATION SYSTEMS
The Jupiter Control System can be connected to a Saturn Master Control Switcher. The Jupiter can also be connected to an
automation computer.
EXTERNAL CONTROL PROTOCOLS
ESbus Tributary − Used by external computers and automation systems sending switch messages into the Jupiter Control
System. It uses one serial port pair for each device.
E−MEM Interface − Provides an interface to the E−MEM Learn and Recall features of the Grass Valley DD Series and
GVG−200 Production Switchers. Also provides switching and statusing capabilities on the DD switcher. The GVG−200 uses
one serial port pair. The DD uses two pairs, one for E−MEM and one for switching.
ASCII Protocol − Used by external computers and automation systems sending switch messages into the Jupiter Control
System. It uses one serial port for each device. Router size is limited to 1000 inputs and 1000 outputs (000−999) on seven
levels.
GRASS VALLEY PARTY LINE CONTROL OPTION
Party line* control panels supplied with existing TVS/TAS 2000 switchers can optionally be incorporated into a Jupiter sys-
tem through the VM 3000 Party Line port.
