13.2 Software Setting
1. The Windows version of the PC must be compatible with the auto conveyor width system.
2. In the Windows Registry, add a DWORD [AutoConveyorWidth] with the value = [1]
13.3 Saving Width Data to Project
1. Adjust the conveyor width with [Auto Conveyor] Function.
2. When saving the project, the system saves the width to the project automatically.
3. If the current width is not the same with the width in project, system shows the dialog
below asking to replace the saved width with current width.
