Synchronized Recording to the External Synchronization Signals (EST)
Synchronized Recording to the External
Synchronization Signals (EST)
The HX-7 has two external synchronization inputs of EST1, EST2 for synchronized recording with
other devices or the camera and exposure timing.

(00400)
The MEMRECAM HX-7 records with the sensor exposure start timing as the standard. This exposure start
timing is synchronized with the synchronization signals in the camera or the exposure start signals externally
input .
Internal synchronization signals (INT):
Synchronizes with synchronization signals (VD signals)
created in the HX-7 camera.
External synchronization signals (EST2): Synchronizes with exposure start signals (EST: External
Shutter Trigger, Exposure Start) input from the EST1 or the
EST2 connector.
If recording using EST, when the input signal shifts from H to L in the ARM or REC mode, exposure starts and
a single image is recorded. The minimum EST signal frequency is 0Hz (
＝ recording temporary stop) and so can
handle very slow speed recording. Additionally, if exposure signals from another camera are input to EST,
simple synchronized recording can be performed.

A “J3 split cable (sold separately) is required for EST2 input.
