OPERATIONAL SEQUENCE FOR LINKAGE
Figure 5−123 shows a detailed view of the CP 3000 and MC 3000 control panels previously shown in Figure 5−121 and listed
in Figure 5−122.
The objective in this example is to use the CP 3000 switcher control panel to assign VTR “VT01” as the “A” input to the
control room’s production switcher, and thereby link the machine to the MC 3000 Machine Control Panel.
For this discussion, it is assumed that switcher output PrdA has already been assigned to the first TAKE key of the CP 3000
expansion panel (the output assignment procedure is described on page 6−24).
[1] SELECT source. The operator presses “VTR,” then “1” on the CP 3000.
[2] TAKE to destination. Operator selects production switcher input “A” as the destination by pressing the first TAKE key
on the expansion panel.
This will cause two things to happen:
— The VTR will be switched into the production switcher as “input A”, and the CP 3000 expansion panel will
show the display mnemonic for the VTR (“VT01”) in the status window.
— The system will check the Machine Control table (Figure 5−122) to see what control panel is associated with
the production switcher. At this point the link is established: the device name of the VTR, which is “VT01,”
appears over the first SELECT button on the expansion panel next to the MC 3000 machine control panel, and
the status of the machine appears as well.
[3] The START and STOP buttons (immediately below the device name) can now be used to operate VT01. Or:
[4] Press SELECT key to assign control of the VT01 to MC 3000 panel to the left.
The full status of VTR VT01, including time code, will appear in the MC 3000 display window.
[5] CONTROL all functions of VT01 using MC 3000.
If a different VTR is switched to production switcher input A, control of the new VTR will be brought to the MC 3000 machine
control panel at the same time. In other words, no matter what VTR is selected as input “A,” a control command entered on
the first button group of the expansion panel will be sent to the correct VTR.
It should be noted that this is the only way to gain control of a machine: it must be done by first selecting the machine with
the switcher. This is true even if the machine does not actually pass through the switcher, as described on page 5−147.
