configuration parameters, the vendor default configuration parameters (Default), and the user
configuration parameters (UserSet).
Three operations can be performed on the configuration parameters, including save parameters
(UserSetSave), load parameters (UserSetLoad), and set the startup parameter set (UserSetDefault). The
UserSetSave is to save the effective configuration parameters to the user configuration parameter set
which is set by the user. The UserSetLoad is to load the vendor default configuration parameters (Default)
or the user configuration parameters (UserSet) to the current effective configuration parameters. The
UserSetDefault is refer to the user can specify a set of parameters which to be loaded into the effective
configuration parameters automatically when the camera is reset or powered on. And the camera can work
under this set of parameters. This set of parameters can be vendor default configuration parameters or
user configuration parameters.
1) The type of configuration parameters
The type of configuration parameters includes: the current effective configuration parameters, vendor
default configuration parameters, user configuration parameters.
The current effective configuration parameters: Refers to the current control parameters used by the
camera. Using API function or Demo program to modify the current control parameters of the camera is to
modify the effective configuration parameters. The effective parameters are stored in volatile memory of
the camera, so when the camera is reset or powered on again, the effective configuration parameters will
be lost.
The vendor default configuration parameters (Default): Before the camera leaves the factory, the camera
manufacturer will test the camera to assess the camera's performance and optimize the configuration
parameters of the camera. The vendor default configuration parameters are the camera configuration
parameters optimized by the vendor in a particular environment, these parameters are stored in the non-
volatile memory of the camera, so when the camera is reset or powered on again, the effective
configuration parameters will not be lost, and these parameters cannot be modified.
The user configuration parameters (UserSet): The effective parameters are stored in volatile memory of
the camera, so when the camera is reset or powered on again, the effective configuration parameters will
be lost. You can store the effective configuration parameters to the user configuration parameters, the user
configuration parameters are stored in the non-volatile memory of the camera, so when the camera is
reset or powered on again, the user configuration parameters will not be lost. The MER-U3 series camera
can store a set of user configuration parameters.
2) The operation of configuration parameters
The operations for configuration parameters include the following three types: save parameters, load
parameters and set the UserSetDefault.
Save parameters (UserSetSave)
: Save the current effective configuration parameters to the user
configuration parameters. The storage steps are as follows:
1) Modify the camera's configuration parameters, until the camera runs to the user's requirements.
2) Use UserSetSelector to select UserSet0. Execute UserSetSave command.
The camera's configuration parameters which are saved in the user parameter set include:
