4.2 Configuring the Camera By Setting Registers
A400k cameras have blocks of mapped memory space known as registers. By reading values
from the registers, you can determine basic information about the camera and information about
the camera’s current parameter settings. By writing values to the registers, you can set camera
parameters and control how the camera’s features will operate. There are three types of registers
in an A400k:
• Inquiry Registers - these registers provide basic information about the camera. Section 4.2.1
explains inquiry registers in more detail, lists the inquiry registers in the camera, and
describes the function of each register.
• Feature Control and Status Registers - these registers let you set the parameters associated
with the camera’s features. Section 4.2.2 explains feature control and status registers in
more detail, lists the feature control and status registers in the camera, and describes the
function of each register.
• Bulk Data Control and Status Registers - these registers let you store and recall sets of val-
ues that the camera uses as a group. Section 4.2.3 explains bulk data and the bulk data con-
trol and status registers in more detail. It also lists the bulk data registers in the camera and
describes the function of each register.
A special binary read/write command protocol is used to read from and write to the registers in the
camera. Read and write commands are sent to the camera via the standard serial link between
the camera and the frame grabber. Section
4.3 describes the binary read/write command protocol
in detail and also provides information on using the serial link. Section 4.4 provides code samples
which illustrate how to use the read/write commands.
