G Connection for emergency recording
When the external switch is turned ON, emergency recording will be started.
Resolution, recording time, recording rate and quality for emergency recording can differ according to the settings of
"Emergency REC" of "Recording" on the SETUP MENU. (Refer to page 112.)
G Connection for external recording changeover
When the external switch is turned ON, the recording program changeover is affected for recording.
The recording program can be set for "EXT" with the "Time Table" of "Schedule" on the SETUP MENU. (Refer to page 121.)
G Connection to synchronize the sequential display changeover (when multiple
units are used)
Sequential display changeover is affected by the timing of supplied signals to the sequence changeover input terminal. When
multiple units are used, the sequence timing can be synchronized.
Setting for the sequence timing can be set with "Sequence Timing" of "Switcher" on the SETUP MENU. (Refer to page 125.)
For the synchronization of the sequence timing between multiple units, there is a difference in the sequence timing setting as
shown below between the synchronized side (Master) and the synchronizing side (Slave).
Synchronized side (Master): Set at "INT" (functioning as an output terminal)
Synchronizing side (Slave): Set at "EXT" (functioning as an input terminal)
