I'm devoloping some system, conntrolled by a DS89C450. I load the program in the serial way, using a PC with true serial rs232, without problem at a rate of 57600 with 11.0562 crystal.
But for ISP, I need to work with my notebook Aser aspire 5552-3343, Windows7, that hasn't any serial port. So I'm trying with many USB to serial cable adapters, but until now I couldn't connect to loader.
I use the same hardware of maxim and the software is MTK2, last version.
With some adapters I have any activity, some comunication, but some others nothing at all.
Some shows it:
Some other only
Anybody knows the source of this problem?
