Working with Multiple Channels
You will probably find one or more channel buttons in the configurable button sections of your
panel. (A channel is an Imagestore 750, LGK-3901, DSK-3901, ISM-3901, or an MCE or an MCPM.)
There are 3 types of channel buttons:
• Channel selection.
• No channel.
• Gang channels.
Channel selection can also be performed in the ‘Channel Select’ menu. However, selecting no
channels or ganging channels requires the use of channel buttons. Channel selection is affected
by “automatic gang mode.” See the discussion of automatic gang mode, following.
You can access the ‘Channel Select’ menu either by pressing a ‘Channel Select’ menu button or
by clicking or touching the ‘Channel’ button in the main menu.
When channels are ganged, one channel is the “main” channel and other channels are
“followers.” The operations you perform are executed on the main channel and are replicated on
the followers.
S Ganged channels must either be all Imagestore 750s or a combination of MCEs and MCPMs.
A ‘No Channel’ button can be used to take the panel out of service for maintenance.
When you select a channel, all status and configuration parameters for the newly selected
channel are downloaded to the panel. A channel change takes approximately one second
(unless you are denied access to the channel). Buttons, main sources, video effect sources, tran-
sitions rates, and salvos can all change according to your specific channel configuration.
Channel changes can be programmed to trigger an NV9000 salvo. Consult your system’s admin-
istrator if you need to determine whether your channel selection buttons trigger salvos.
Channel Selection with Buttons
To change channels, press the button (in the configurable button section) for the channel that
you want to control.
When you perform a channel change, the new channel button flashes red for an moment, indi-
cating that the system has acknowledged the change request. When the channel is ready, the
button goes high tally green, unless there is a problem in which case the button stays red.
Channel Selection in the Menus
Follow these steps to change channels in the ‘Channel Select’ menu:
1 Press the ‘Channel’ button in the main menu to display the ‘Channel Select’ menu. The menu
displays a list of channels. The currently selected channel is highlighted.
2 To select a channel, touch a list entry. You might have to scroll the list to find the entry you
want. The channel change executes immediately although it takes approximately a second
to complete.
