WID511, WID512, and WID513 release 2.0.5 contains a fix to the following problem found in software versions 2.0.2 and 2.0.3:
- WID software had a vulnerability to incorrect serial line communication. Repeatedly occurring incorrect messages (for example, corrupt data due to wrong configuration or communication line fault) caused WID runtime memory to be allocated, and after continuous use for a long time the high memory usage finally caused the software processes to freeze. This resulted in device freezing: the displayed data was not updated and the touch screen became unresponsive.
- Affects WID511, WID512, and WID513.
