Make sure to connect the computer with Celis, with a null-modem cable (part no. 365088) before starting the Celis Programmer software.
When the Celis Programmer has started it will ask you to turn the machine OFF and then ON again. What will happen is that when Celis is powered on it will look if it is connected with a computer running the Celis Programmer software. If connected the display will show "WAITING FOR MAIN" indicating that it is connected to the computer. If it continues to start up and initializes the computer and Celis Control is not connected. Check the connection and try again.
