6. Touch the Linked Bus data pad again in the Table Setup pane and select
another linked bus.
Repeat this process for each controlling and linked bus you wish to add
to the cascading links.
7. If desired, assign different source tables to the bus links:
a. Touch a Linked Bus data pad in the Current Link pane.
b. Touch a source table in the Table Setup pane.
Note that the Inhibit All Links button at the bottom of the Current Links pane
must be off for the links to be active.
Bus Linking Restrictions
• The Switched Preview, Primary Preview, and Image Store input buses
cannot be configured as Linked buses.
• An Aux bus associated with a DPM cannot be configured as a Control-
ling bus. However, these buses may be configured as Linked buses.
Link Management
Individual bus links are enabled and disabled with the Link Enable button in
the Controlling bus pane. When enabled, commands will be sent from the
Controlling bus to the Linked bus, provided all links are not inhibited (see
below). Link Enable is keyframeable.
Other controls on this menu can be used to manage bus links.
Bus Hold Inhibits Links – This control affects the behavior of the Control Panel
Hold button for all Linked buses. When Bus Hold Inhibits Links is On and the
Hold button on a Linked bus is also On, that Linked bus will ignore bus link
commands and will not change sources when Controlling bus sources
change. Note that the
Hold button retains its existing functionality, keeping
that bus from changing sources when an E-MEM register is recalled.
Inhibit All Links – Overrides all Link Enable settings to disable all active bus
links. This does not change the individual Link Enable settings, however.
Turning Disable All Links off will re-enable any bus links with Link Enable on.
Bus Linking Operation
Once the Bus Linking associations have been established and are enabled,
selecting a source on a Controlling bus that is associated with a source on a
Linked bus will make the Linked bus select its associated source. The fol-
lowing special operating rules apply.
