Hi After two weeks, still in trouble.
1 - I DO know that the Mac + USB/serial cable are working : no problem to communicate with K3 and P3 2 - if you don't trust me I also used a PC with another USB/serial... 3 - I checked many time the 2 ribbon cables on the I/O board of the KPA500 4 - I put a NEW I/O board send by Electraft ... 5 - At the first attempt, good communication with the KPA500 and beginning of the firmware load..(STBY led flashing nicely...) 6 - after 30 sec message : MCU load failed 7 - after MANY others tests - no (or sporadic) communication with KPA500 (using MAC or PC) It looks that something is wrong with the CPU ?? Is it possible to reset the CPU ? Any help will appreciated but (please) IT IS NO a problem of computer .
