Polarity and choice of exter nal triggers

7.11

Introduction

7.11.1.

Controlling integration and read-out in each one of the control inputs can be done by every one of the
CC1..CC4 and/or the external trigger input on the I/O-connector. Which control signals control which
event is fully programmable.

It is also possible to change the polarity of each one of the trigger signals.

Exposure control

7.11.2.

Exposure control is done by means of the Camera Control Exposure command. This is applicable in
the following modes:

Normal control mode

•

Delayed transfer control mode

•

Double transfer control mode

•

Double delayed transfer control mode

•

Command structure: CCEe;f

Where e and f are defined in the table below

The actual camera control event setting can be read back from the camera
