External Devices 11 Chapter 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. Notes • 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 478). • To use a disk recorder, the target file from the file list must be loaded. For details, see "Disk Recorder File Operations" (page 293). 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 296) (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 Notes • 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 281
