Synchronized Signal Selection (Sync Sel); Setting Method; Synchronized Est Signal Recording - Memrecam GX-5 User Manual

3.2.12 Synchronized Signal Selection (SYNC SEL)

While in STOP mode, the synchronized signals can be selected from the SYS MENU on the JPAD3.
The MEMRECAM GX-5 uses the starting time for sensor exposure as the standard for recording. The
exposure time is synchronized with the internal time signals or the external time signals shown below.
 Internal Time Signals（INT）
Synchronized with the synchronized signals (VD signals) in the camera.
 External Time Signals（EST1,EST2）
If EST1 or EST2 are selected, the exposure start signals (EST：External Shutter Trigger,
Exposure Start) input from the J1 cable EST1 connector or the J3 cable EST2 connector are the
standard. The minimum frequency for the EST signal is 0Hz so ultra high speed recording is
possible.

3.2.12.1 Setting Method

1) While in STOP mode, press MENU
MENU.
2) Use the arrows
MENU, and then press SET
3) Use the arrows
MENU (Figure 3-40).
4) Use the arrows
INT Synchronized with the internal synchronization signals of the camera
EST1 Synchronized with the EST1 signal from the J1 connector
EST2 Synchronized with the EST2 signal from the J3 connector
The EST1 signal and the EST2 signal are handled in an identical manner but cannot be used at the same
time.
It is possible to set the polarity of the exposure start signal from the EST1 connector and the EST2
connector. Refer to【3.2.13 External Input/Output Signal Polarity Selection】.

3.2.12.2 Synchronized EST Signal Recording

3.2.12.2.1 Precautions for Use
1) Filter Value Settings
If there is noise in the EST signal, set a noise filter value to activate the filter.
Refer to the【3. 2.14 EST Filter settings】for the setting method.
2) Timing Restrictions
The relationship between the cycle for the EST signal and the maximum recording speed must fulfill
the following conditions. If they are not met, proper recording is not possible.
EST signal cycle ＞ 1 ／ maximum recording speed
The relationship between the cycle for the EST and the shutter exposure time must also fulfill the
following conditions. If they are not met, proper recording is not possible.
EST signal cycle ＞ shutter exposure time＋5.84μsec
