Re: Phaser 3020 print Exception Report / message: Assertion failed

Hi Marek_PL, 

Thank you for using the Support Forum. Please try disabling the the bi-directional communication in the driver and see if that will fix the issue.  Please see this article for information on how to disable bi-directional communication on the port.  In the article it says to enable you will disable. If that does not help please consider contacting you local support centre for additional assistance.  

Thanks,
