Control of P-Bus Devices
You can control P-Bus (Peripheral Bus II protocol)
external devices through the 9-pin serial port or network
port of an SIU.
P-Bus device control modes
There are two modes of P-Bus device control, as follows.
Trigger:
Operating a previously specified button outputs
the command for an action assigned to that button.
Timeline:
Carrying out a keyframe effect under the
control of the center control panel controls external
devices.
In the Setup menu, select which of Trigger mode and
Timeline mode to use.
You can set the following actions (set what action
command is output to which device) in both modes.

Creating and Editing the P-Bus
Timeline
You can set actions at keyframe points on the P-Bus
timeline. At any single keyframe point, you can set actions
for a maximum of 24 devices.
For details about keyframe creation, see “Creating and
Editing Keyframes” (page 310).
For the action setting (P-Bus timeline editing), use the
Device menu.
The data set in the Device menu can be saved in a
keyframe effect register. Recalling the register starts
execution of the keyframe effect, and when this reaches the
keyframe point at which actions are set, action commands
are output to external devices from the port of the SIU.
To use the P-Bus timeline, the P-Bus control mode must be
set to [Timeline] in the Setup menu

“Action” list on the right, select the action.
