Trigger Control
The camera allows Frame Start trigger controls to be performed via external trigger signals.
The Frame Start trigger allows exposure control via the trigger signal inputs.
The settings for exposure control and triggers are related to each other. Be sure to configure the settings
described in “Configuring Exposure and External Trigger Settings” (page 18).
Shortest Repetition Period for Triggers
The reciprocal of the maximum frame rate is the time required to output one frame. The shortest
repetition periods for triggers cannot be lower than that value.

* GO-2400M-PMCL only
Exposure and readout cannot overlap on the GO-2400-PMCL. The above table indicates the shortest
trigger periods for the shortest exposure times. By adding the value of the exposure time you are
using to the values in the table, you can determine the shortest trigger periods under your own usage
environment.
