■ Recording in the Continuous External Trigger Mode [R-External SYNCIN]
This mode allows repeatedly recording frames using the external trigger mode [External
SYNCIN].
This section describes recording when the master camera is set in the external trigger
mode [External SEPARATE].
First, configure settings on the slave camera.
In "Selecting the Recording Mode in [REC] – [MODE]" in 5.4.1 Setting Recording
Parameters, specify [R-External SYNCIN] to use as the recording mode. Then click
[REC]. The system waits until standby and trigger signal inputs from the master camera
are detected.
Then, configure settings on the master camera.
In "Selecting the Recording Mode in [REC] – [MODE]" in 5.4.1 Setting Recording
Parameters, specify the external trigger mode [External SEPARATE] to use as the
recording mode. Then click [REC]. The window in Fig. 5-16 is displayed and the system
waits until standby and trigger signal inputs from the master camera are detected.
About 850 ns after the standby signal is input, it starts waiting for the trigger signal. After
the trigger signal is input, it records the specified number of frames and reads the image
data. Then, it immediately starts waiting for input of the next standby signal. This process
is then repeated.
To not record or to stop recording before it is finished, click [REC STOP].
The image specified in "Selecting First Frame to Display" in 5.5 Playing Back Images, is
displayed in the Viewer window.
Then, the window in Fig. 5-16 is displayed and the system starts waiting for recording and
an external signal.
The "NOW RECORDING" window shown in Fig. 5-16 indicates the current number of
times recording was performed.
The standby signal and trigger signal operations of the slave camera are approximately 110 ns
delay from the operations of the master camera. Adding approximately 110 ns to the [TRIGGER]
– [DELAY] and [STANDBY] – [DELAY] values of the master camera improves the
synchronization accuracy of videos.
Synchronized recording is performed by allowing the slave camera to share the master camera’s
timing signal to start recording. For this reason, the slave camera needs to enter a status waiting
for the timing signal to start recording sent from the master camera before the master camera
sends the signal. During synchronized recording, set the recording mode of the master camera to
a mode other than [R-External STANDBY], [R-External TRIG], and [R-External SEPARATE].
To stop synchronized recording, stop recording on both cameras.
