2.5.1Setting

This menu deals with optional settings, such as communication, and specifying paths for the software. This selection brings up the Setting dialogue box, which consists of the Directory, CPU Speed, and other options depending on the programmer. Grayed area is not selectable for the model.

Directory: You may change where the files and libraries are located. User will have a chance to set this at time of the installation.

CPU Speed: On some early PCs, the parallel port is unable to keep up with the data rate normally used to communicate with the programmer hardware. In this case you should set the speed to Low in CPU Speed.
