Control Panel Operation VGA Display
6−144 VN 3000 Installation and Operating Manual
Delegation and linkage status of each machine is shown as follows:
BLANK The machine is not delegated or linked.
“ASSIGNED” The machine has been delegated to this group but no link has been made.
“PANELNAME” When the name of a specific control panel appears (such as “StuMC”), it means that (1) the
machine has been delegated (using an MC 3020D) to the group indicated, and that (2) a link
between the machine and the panel has been established using the distribution switcher.
The VGA can display as many as 32 delegation groups, compared to the 20 groups that can be identified by an MC 3020D
Delegate Panel. Creation of a 21st delegation group, and delegation of a machine to that group using the VC 3020, would
thus prohibit operation of the machine by a control panel in any of the first 20 groups.
CURSOR MODE − SELECTING A MACHINE FOR CONTROL
To enter cursor mode, press SELECT on the VM 3000 (or CURSOR MODE on the CP 3020). This will cause
the name of the first machine to appear in reverse video. When in cursor mode, the UP and DOWN buttons (or
arrow buttons) will move the cursor from one machine to another. A machine pointed to by the cursor is automati-
cally selected as the machine to be controlled by the adjacent MC 3000 Machine Control Panel (i.e., the MC 3000
connected to the VM 3000 providing the VGA display).
Note that the MC 3000 can send control commands to any selected machine, even when the machine has not been
delegated (“assigned”) to any delegation group.
Important: As a supervisory system, the VGA / MC 3000 can send control commands to any machine, even
to a machine linked to and being controlled by another panel. In this condition both panels will be able to
send commands. However, the VGA can take exclusive control by using CHANGE MODE as described
below.
Note: Since the VGA / MC 3000 cannot normally link itself to a machine, time code will not be shown in the
MC 3000 window. Linkage and display of time code under these circumstances is discussed in a note on page
5−156.
Change Mode − Changing Delegation of a Machine
This function is available with the CP 3020 panel only.
While in Cursor Mode, the CHANGE MODE button can be used to “un−delegate” a machine. To do this, the
cursor is moved to the row showing the desired machine, then, using the RIGHT and LEFT keys, to a delega-
tion group column showing the word “Assigned” or the showing the name of the panel now linked to the
machine. When CHANGE MODE is pressed, the delegation/link will be cut and the VG 3000/MC 3000 will
have exclusive control. If CHANGE MODE is pressed again, the machine will again be delegated to the
group shown at the top of the column; however, another associative switcher Take will have to occur to re−
establish the link.
Note: Even after a machine is un−delegated by the VGA, it can still be re−delegated at any time with an MC
3020D panel.
