Configuration of the camera

STINGRAY Technical Manual V2.2.0

Configuration of the camera

All camera settings are made by writing specific values into the correspond-

ing registers.

This applies to:

• values for general operating states such as video formats and modes,

exposure times, etc.

• extended features of the camera that are turned on and off and con-

trolled via corresponding registers (so-called advanced registers).

Camera_Status_Register

The interoperability of cameras from different manufacturers is ensured by

IIDC, formerly DCAM (Digital Camera Specification), published by the

IEEE 1394 Trade Association.

IIDC is primarily concerned with setting memory addresses (e.g. CSR:

Camera_Status_Register) and their meaning.

In principle all addresses in IEEE 1394 networks are 64 bits long.

The first 10 bits describe the Bus_Id, the next 6 bits the Node_Id.

Of the subsequent 48 bit, the first 16 bit are always FFFFh, leaving the

description for the Camera_Status_Register in the last 32 bit.

If a CSR F0F00600h is mentioned below this means in full:

Bus_Id, Node_Id, FFFF F0F00600h

Writing and reading to and from the register can be done with programs such

as FireView or by other programs developed using an API library

(e.g. FirePackage).
