A) I cannot set CROMATICA in re-programming STATUS:
In some situations there might be a tension variation which does not allow CROMATICA to reach reprogramming status. Unplug and re-plug CROMATICA from the power supply and execute the RESET procedure (i.e. push the reset button with a nail for 5 seconds)
B) CROMATICA is not recognized as valid USB device:
When you connect CROMATICA to your windows PC, the system automatically searches for the right driver to communicate with CROMATICA. In some situations the PC system cannot find the right driver to communicate with CROMATICA and a message “USB device not recognized” is displayed. In this case you need to manually download and install the right driver at the following LINK. Unzip the archive and run the Driver Installation Tool. IMPORTANT NOTE: You must re-boot your PC after the driver installation and before you attempt a new CROMATICA Update.
C) Message “Cannot open port”:
Once you have clicked on the “Upload” button of the firmware loader a message “Cannot open port” is displayed. This situation can happen because the system cannot recognize CROMATICA as a valid USB device or because you are using the wrong COM port. In the first case please follow the procedure at Point B). In the second case you are using the wrong COM port from the list of available ports a need to select the COM port to which CROMATICA is associated. To simplify this step please make sure no other USB devices are connected to your window PC.
