3.13.3 Identical Dark Images Indicate a Parameter Error
If the camera detects that a parameter error is present, it will automatically switch into a mode
where it outputs identical dark images. In this mode, all of the pixel values in each captured line
will be low and the pixel values in any one of the captured lines will be identical to the pixel values
in all other captured lines of the same color. For example, if you check the pixel values of a
captured blue line, you will find that the pixel values are low and that they are identical to the pixel
values in every other captured blue line.
A parameter error indicates that a parameter is set out of range, that a parameter is set to an
invalid value or that parameters which depend on each other are set in conflict.
Since the CCT+ automatically checks that parameters are set correctly, you will not normally see
a parameter error situation when you set parameters with the CCT+. When you set parameters
using binary commands, you may see parameter error situations if you inadvertently set
parameters to values that are not allowed or are in conflict. If you suspect that the camera is in a
parameter error situation, you can read the value in the Camera Status field of the Camera Status
inquiry register (see page 4-9). If the parameter error bit is set, then a parameter error situation is
present.
A simple way to recover from a parameter error situation is to activate the camera’s factory
configuration set (see Section 3.17.3). Activating the factory set will load a set of factory-
determined optimal parameters into the camera.
Whenever you set the camera’s parameters by using binary commands to write to registers, make
sure you check the min, max and increment fields of each register before you set the parameter
values. Setting the values within the min and max and using the specified increments will avoid
parameter errors.
3.14 Checking the Camera Status
During operation, L304kc cameras perform a continuous series of self checks. You can view the
current camera status in several ways:
• by using the Camera Configuration Tool Plus (see Section 4.1). Check the Camera Status
parameter in the Camera Information parameters group to see if any error codes are present.
• by using binary read/write commands from within your own application to read the value in
the Camera Status field of the Camera Status inquiry register (see page 4-9).
Section 4.2.1 explains inquiry registers and Section 4.3.1 explains using read/write
commands.
• by checking the LED on the back of the camera. If certain error conditions are present, the
LED will blink (see Section 6.1).
3.15 Status LED
The L304kc has a status LED on the back of the camera. The LED is used to indicate that power
is present and to indicate an error condition if one is detected. See Section 6.1 for details.
