9.3.2 Modes of Operation
The AT-200GE has multiple operating modes including a normal continuous mode, triggered
modes and others. In the normal continuous mode, the camera runs at 15.4 frames per second
continuously. This is used for operation when a trigger signal is not required. There are 5
triggered modes and the trigger signal is supplied via HIROSE 12-pin or D-Sub 9-pin connectors.
In the triggered modes, the frame rate is 15 fps.

Normal continuous mode

Edge pre-select trigger mode (EPS)

Pulse width control trigger mode (PWC)

Reset continuous trigger mode (RCT)

EPS Sequential trigger mode

Frame delay readout trigger mode (EPS and PWC)

Smearless mode

OB transfer mode

Multi ROI mode

9.3.3 Partial scan (Fast Dump ON)
The partial scanning function uses the middle of the image vertically to achieve faster frame
rates. This is very useful when capturing and inspecting an image which does not require the
full height.

Partial Scan

Fig.22 Partial scan conceptual drawing

The partial scan mode for the AT-200GE is variable. The first line and the last line to be read
out can be set.

The variable scan read out is connected with the ROI settings.
1. If ROI is set, these settings are applied to the partial scan settings.
2. If the multi ROI feature is used, the smallest line number and the largest line number of

the multi ROI areas define the partial scan area.

3. When the sequence trigger is used, the situation is the same as for multi ROI. The smallest

line and the largest line define the partial scan.


In order to execute partial scanning, the fast dump setting should be ON.

The first line can be set anywhere from the 1

st

line to 1229

th

line and the end line can be set

from the 8

th

line to 1236

th

line. This means the minimum height of the partial scan is 8 lines.
