Synchronized Record Timing
Synchronized Record Timing
Recording can be synchronized to the timing of a device connected to the MEMRECAM HX-7.
4-61
(00400)
The HX-7 uses internal camera time and recording is synchronized to that time. Recording can be done by
synchronizing the time and frame with another device by synchronizing with the device that outputs the
IRIG-B time code for this time or the GX-HUB sold separately.
Camera time synchronization:
Time synchronized with the camera timer. Select if operating with
just a camera or if precise time synchronization is not necessary. (If connected to a
control PC, time synchronization is done with the PC timing)
GX-HUB time synchronization:
Time synchronized with the GX-HUB timer. Select if operating with a
multi camera connection using the GX-HUB. If connected to a control PC, time
synchronization is done with the PC timing. If not connected to a control PC, recording
with multiple cameras is synchronized but the exact time (day/hour/minute/second) is
not available.
IRIG time synchronization: Time synchronized with the IRIG-B timer code. Select if the following occurs.
■ If using only the MEMRECAM HX-7 and inputting the IRIG-B timer code from the
J3 common cable (sold separately) IRIG-B input connected to a REMOTE connector.
■ If inputting the IRIG-B timer code to the GX-HUB with multiple cameras connected
using GX-HUB (a combination of the HX series and the GX series is possible).
IRIG-B Signals
Standard IRIG Standard 200-98
Recommended voltage 3Vpp
Allowable input voltage 1 ～ 10Vpp
Other High impedance, isolation transformer input
Trigger RESET:
Resynchronization with trigger input signals. Select if using trigger signals to
synchronize with an external device. The HX-7 recording time precision will be ±0.01%
or less. If synchronizing time with trigger RESET, there may be significant
discrepancies with the time from the trigger input signal timing.
