Mode input (pin 9)

The mode input provides a method for switching the camera between different

exposure control modes using an externally applied signal.

The indiviual function depends on the camera variant. The GigE Vision feature

AcquisitionControl/TriggerMode can be used to switch the mode via software.

Bigeye P-132

The mode input switches between the continuous free-running operation with

fixed 80 ms exposure time on the one hand and the image-on-demand mode

(IOD) on the other hand.

For long-term exposures the image-on-demand mode (IOD mode) generally has

to be activated. As a cooling of the sensor is only advantageous at longer expo-

sure times, the cooling is generally only activated in the IOD mode. In the con-

tinuous mode the cooling is switched off. This feature allows to reduce the

power consumption of the camera during standby. After re-enabling the IOD

mode a cooling time of approx. 4 – 5 minutes is needed.

Input pin 9: open (or TTL high)  continuous operation (cooling off)

GND (or TTL low)  image-on-demand (cooling active)

Bigeye P-629

This camera variant is always in image-on-demand mode and does not support

continuous mode. Instead, this signal controls the behavior of the mechanical

shutter.

The shutter is automatically closed during the read-out of the sensor, in order

that no smear will take place. If a pulsed light source is used, the shutter needs

not to be closed. This can be forced by the corresponding mode setting.

Input pin 9: open (or TTL high)  shutter permanently open

GND (or TTL low)  shutter closed during image output

Bigeye P-1100

The mode input switches between the continuous free-running operation with

fixed 635 ms exposure time on the one hand and the image-on-demand mode

(IOD mode) on the other hand.

For long-term exposures the image-on-demand mode (IOD mode) generally has

to be activated. As a cooling of the sensor is only advantageous at longer expo-

sure times, the cooling is generally only activated in the IOD mode. In the con-

The active state (externally low or TriggerMode = On) is domi-

nant, thus image-on-demand mode is active, if one of either

settings is.
