Their support is quite incompetent and could only say that start address is 0x443 and stop 0x43 and that the logic is implemented in custom ASIC. The weirdness is that i found no way to "ping" or refresh the timer .. if i activate it .. it fires in specified interval (set by jumper) .. BUT even if i stop and start the timer before firing it doesnt defer the activation! I tried experimenting with different possible ways to control it (trying writing different values to the port, tried also other addresses), but to no avail. I believe they would not build unusable watchdog so i am hoping there is a way .. does anyone have an idea what other ways could i try? Thanks and regards, Peter -- Peter Kundrat peter@kundrat.sk
