7-1. Outline
In this system, a function to control 4D system is available. The 4D system control function consists of
the following two components.
.
To output LTC (Longitudinal Time Code)
.
To send control command for external equipment by network automation cue.
Each of the above can be used individually.
n
Sony does not guarantee that this function is compatible with all existing 4D systems.
Since configurations of existing 4D systems are different from each other, each system must be properly
configured. Some 4D system needs both LTC output and network automation cue, some needs only LTC
output and some needs neither of them. For details, contact your local Sony Sales Office/Service Center.

7-2. LTC
Output
LTC is output from No.7 pin of AUDIO OUTPUT BAL port (refer to Section 4-1) of the main projector
in synchronization with the picture frame.
n
The LTC output is assigned to No. 7 pin of AUDIO OUTPUT BAL port. If the AUDIO OUTPUT BAL
port is already connected to the audio processor, the LTC output needs to be tapped from AUDIO OUT-
PUT BAL cable/connector. Be sure to confirm the connecting cable before 4D function is activated.
