External Devices
Control of External
Devices
You can control operations on the following types of
external device.
• P-Bus (Peripheral II protocol) devices
• GPI devices
• VTRs (Sony 9-pin VTR protocol)
• Disk recorders (video disk communications protocol,
Odetics protocol)
• Extended VTRs (Abekas A53 protocol)
1)
• AMP (Advanced Media Protocol) compatible devices
1)
1) Unless otherwise specifically stated in this document, “disk recorder”
includes Extended VTRs and AMP compatible devices.
You can also operate external devices controlled by other
protocols over a network using general-purpose TCP/IP
connection settings.
For details about the devices that can be connected, consult
your Sony representative.
Control of GPI devices
Operate external devices using the GPI output port of an
SIU.
Control of P-Bus devices, VTRs, and disk
recorders
Operate external devices using the 9-pin serial ports or
network port of an SIU.
• The maximum number of ports that can be used for
external device control on a single SIU, including 9-pin
serial ports and network ports, is 40.
• Control of P-Bus compatible devices, AMP compatible
devices, and TCP/IP connected devices is supported on
network ports.
• Control of AMP compatible devices is not supported on
9-pin serial ports.
• The connection ports must be configured in order to
operate devices connected to the 9-pin serial ports or
network ports.
For details, see “Configuring the Connection Port of
External Devices” (page 480).
• To use a disk recorder, the target file from the file list
must be loaded.
For details, see “Disk Recorder File Operations”
(page 294).
Shared Functions for External
Device Control
Keyframe functions
There are 250 registers, numbered 1 to 250, holding
external device control data as keyframe data (see
page 297) (only 99 registers for the GPI timeline).
The available keyframe functions are as follows.
• RECALL (1 to 250), STORE (1 to 250), RECALL
UNDO, STORE UNDO, empty register search, AUTO
SAVE, RECALL MODE (RECALL, RECALL &
REWIND)
• EDIT ENABLE, EDIT UNDO
• CONST DUR, EFF DUR, KF DUR, DELAY, PAUSE,
INSERT BEFORE, INSERT AFTER, MODIFY,
DELETE, COPY, PASTE BEFORE, PASTE AFTER,
FROM TO, ALL
• PREV KF, NEXT KF, GOTO TC, GOTO KF, RUN,
REWIND, FF, STOP NEXT KF, NORMAL, JOG, KF
FADER
• An action set for a keyframe is only executed when the
keyframe effect is executed in the forward direction.
Take care when executing simultaneously with a
switcher or DME keyframe effect, since the actions are
not executed in the reverse direction.
• The following keyframe functions cannot be used.
- KF LOOP, EFFECT LOOP, REVERSE, NORMAL/
REVERSE
- PATH
