Hi,
I have an analytical instrument with a “1802421 Rugged Giant” board/chip inside. It seems that the included battery has failed. After replacing the battery the instrument does not run, does not show any diplay information on the included LCD, does not react to user input on the membrane keypad and does not react to PC communication.
With one exception: the instrument has a “data” and a “program” RS232 interface. With a terminal connected to the program interface I could make the instrument beep on some input while on on other it is silent. I.e. there seems to be a menue running but I do not know what happens and I do not see any output on the terminal.
The company producing the instrument seems to be gone for good and the programmer (some Mr. Urbancyk, if by chance he is known here) cannot be found.
To my questions:
What are the chances that the program is still there and just needs to be started?
How do I find out if my board has only RAM/EPROM or some other configuration?
Is there some documentation to load and start programs?
What would you recommend to do?
TIA
Michael
