status. In order to acquire more frames, you must apply a new acquisition start trigger signal to the

camera to exit it from the "waiting for acquisition start trigger" acquisition status.

When the Acquisition Start Trigger Mode parameter is set to on, you must select a source signal to

serve as the acquisition start trigger. The Acquisition Start Trigger Source parameter specifies the

source signal. The available selections for the Acquisition Start Trigger Source parameter are:

Software - When the acquisition start trigger source is set to software, the user applies an

acquisition start trigger to the camera by issuing an acquisition start TriggerSoftware command

to the camera from the host PC.

Line 1 - When the acquisition start trigger source is set to line 1, the user applies an acquisition

start trigger to the camera by injecting an externally generated acquisition start trigger signal

(commonly referred to as a hardware trigger signal) into physical input line 1 on the camera.

If the Acquisition Start Trigger Source parameter is set to Line 1, the user must also set the

Acquisition Start Trigger Activation parameter. The available settings for the Acquisition Start

Trigger Activation parameter are:

Rising Edge - specifies that a rising edge of the hardware trigger signal will act as the

acquisition start trigger.

Falling Edge - specifies that a falling edge of the hardware trigger signal will act as the

acquisition start trigger.

6.3.2

When the Acquisition Start Trigger Mode parameter is set to on, you must set the value of the

camera's Acquisition Frame Count parameter. The value of the Acquisition Frame Count can range

from 1 to 255.

With acquisition start triggering on, the camera will initially be in a "waiting for acquisition start

trigger" acquisition status. When in this acquisition status, the camera cannot react to frame start

trigger signals. If an acquisition start trigger signal is applied to the camera, the camera will exit the

"waiting for acquisition start trigger" acquisition status and will enter the "waiting for frame start

trigger" acquisition status. It can then react to frame start trigger signals. When the camera has

received a number of frame start trigger signals equal to the current Acquisition Frame Count

parameter setting, it will return to the "waiting for acquisition start trigger" acquisition status. At that

point, you must apply a new acquisition start trigger signal to exit the camera from the "waiting for

acquisition start trigger" acquisition status.
