Thank You mathey. Maybe the problem is that I just have a laptop with adaptor. I turn on the receiver but I see on screen "Syncronising stb's, please reset target! ...". But it doesn't go on.
i use one of these and they do work . the settings on erom are important follow the suggested ones
check your devices on your laptop to see which com port the serial rs232 is on and be sure to use that exact port in the erom settings
