Trigger Shift
The camera can perform exposure by the next trigger
even during image transmission (except in Special
Trigger mode). In such case, as the trigger signal can be
a noise source, use the camera with Trigger Shift
activated. When Trigger Shift is active, the time between
trigger input and start of exposure is automatically
adjusted to avoid noise generation, causing a delay of
one line at maximum in starting exposure. When Trigger
Shift is deactivated, the delay adjustment is not made
and exposure always starts with the same timing, but
noise may be mixed into images. Even if Trigger Shift is
active, triggering may be disabled, or exposure may be
defective while an image transmission is in progress and
the next transmission cannot be started. Select a
sufficient trigger interval (see "Trigger Input
Specifications" (page 8)).

Trigger Inhibit
This function disables the camera's trigger input. When
multiple cameras are connected, use this to disable
triggering for only specified cameras or to eliminate
malfunction due to noise mixed in the trigger signal line
from the setup environment.
