Manufacturer provides DAMI-C users with an opportunity of upgrading embedded firmware by the means of serial port communication with an external PC with launched NDT Software Environment program. This feature allows to be up-to-date with the latest versions of embedded firmware, available from VOTUM JSC, www.votum.md . The process of firmware rewriting should be performed with care, because in the case of failure during this procedure device becomes dead until successful rewriting procedure takes place. NDT software environment supports the mode of firmware rewriting. Firmware is contained in a single file "dami.bin". Download the latest version of "dami.bin" from www.votum.md or use the file "dami.bin", provided in DAMI-C tool kit. The following steps shall be performed in order to rewrite embedded firmware: 1. At the beginning of firmware rewriting procedure both DAMI-C and external PC should be turned off. 2. Connect DAMI-C to the external PC using RS 232 cable. 3. Turn the external PC on. 4. DO NOT Turn DAMI-C on! 5. Press ENTER + SHIFT keys on DAMI-C.

Device will turn to the firmware-rewriting mode, it will beep shortly and will flash front panel LED once. 6. Run the NDT Environment Software. Configure communication port as indicated in NDTSW Using Guide. 7. For firmware loading select in main window menu "DAMI Link | Load Boot Program". There will appear a window allowing to select boot file name and to load this boot file into connected DAMI-C device. 8. Select boot file name and press Load button. This action will start the loading process. You will see the progress bar at the bottom of the window. It is required to wait until loading process will be completed.
