Enabling the External Trigger Feature

To enable the external trigger feature:

• Set the On/Off field of the Trigger Mode control register to 1 to enable triggering.

• Set the Trigger Polarity field of the Trigger Mode control register to 0 to select falling edge

triggering or 1 to select rising edge triggering.

• Set the Trigger Mode field of the Trigger Mode control register to 0 to select the programma-

ble exposure mode or 1 to select the level controlled exposure mode.

• Set the Trigger Source field in the Trigger Mode control register to select which one of the

four physical input ports on the camera will be used to receive the external trigger signal:

- Set the Trigger Source field to 0 to select physical input port 0 to receive the ExTrig signal.

- Set the Trigger Source field to 1 to select physical input port 1 to receive the ExTrig signal.

- Set the Trigger Source field to 2 to select physical input port 2 to receive the ExTrig signal.

- Set the Trigger Source field to 3 to select physical input port 3 to receive the ExTrig signal.

The default setting is for physical input port 0 to receive the ExTrig signal. Refer to Sections 2.5.1

and 2.5.2 for a description of the physical and electrical characteristics of the physical input ports.

The Trigger Source field in the Trigger Mode register is defined in version 1.31 of the

IIDC specification.

Because the Trigger Source feature is so new, the Basler BCAM 1394 Driver does not

yet include a method call to access this feature. As a work-around, you can use the

techniques described in the tutorial for the Basler Smart Features Framework Soft-

ware to directly read from or write to the Trigger Source field.
