4.3.4. Synchronizing Multiple FASTCAM Multi Systems
(Multiple Unit Synchronized Recording)
The system can perform synchronized recording by synchronizing multiple units using external
synchronization input/output.
Conceptual Diagram of Synchronous Connection
Synchronized recording settings using the system are made with the "remote controller (optional)"
or PFV. The conceptual settings when performing synchronized recording using two systems are
explained here. First, decide which camera to make the master camera (outputs the synchronization
signal) and the slave camera (receives the synchronization signal) from the two systems to use for
synchronized recording.
Setting the Master Camera (Outputs Synchronization)
Set the signal output for the master camera which will output the synchronization signal. Synchronization signal
settings are made with the PFV.

For PFV (Standard)
1. Verify that the camera mode is in LIVE mode (the image displayed is passed through from the
camera). If the system is in a mode other than LIVE mode, check "Live" on the camera
control panel.
2. Select I/O on the left tree from "Camera Option" on the camera control panel.
3. Set "GENERAL OUT1".
Setting the Slave Camera (Receives the Synchronization Signal)
Next, set the synchronization signal input for the slave camera which will receive the synchronization signal
supplied by the master camera. Synchronization signal settings are made with PFV.

For the setting method of the signal inputted into GENERAL IN, refer to
“4.4.1.GENERAL IN Signal
