2.3.2. Sync Timing in Multi-Camera Operations
In multiple-camera operation of FASTCAM-512PCI cameras, if sync and trigger signals are
connected in series as shown below, signal delay inevitably becomes obvious. In extreme cases,
this delay may cause an offset of one full image frame between cameras involved in
multiple-camera operation. To avoid this drawback, other connection methods shown in 2.4.2. are
recommended.
