Connecting external sources to the camera

Before you can begin to externally trigger your camera, you need to connect the necessary trigger signal

source to the camera. To do this you need to ensure that you have a 6-pin miniature circular DIN cable and

ensure that the pin-outs are set correctly from your trigger source. Refer to Appendix A for further details on

pin assignments and a diagram of the mini-DIN connector.

There are several ways that you can provide an external pulse to the camera, one of them being via the

QImaging External Trigger Board, which is available through QImaging, and another common device is a

function generator. To trigger the camera, you need to provide a 5V TTL pulse though the pin stated in

Appendix A.

To ensure that you will use the external triggering mechanism correctly, it is important to ensure that the

following questions have been answered when setting up your system design:

• Has a system design been developed that incorporates the necessary elements such as:

a timing diagram;

a simple state diagram or "flow of events";

necessary components including microscope, flash lamp, shutter, etc.;

a software solution for extracting and/or processing your images; and

and external triggering source (e.g. QImaging trigger board, function generator, etc.).

• Have you determined the type of triggering mode you require for your application?

• Are you sure the settings in the camera have been set correctly? For instance, are you monitoring

the SYNC B output, and if so have you set the correct output mode for your system?

The above list should be used as a guide and should be consulted before contacting QImaging Technical

Support.
