After a long period with problems connecting RRC 1258MkII in the control end, together with TS480 (display) and the HRD program, i have got the solution.
My laptop does not have the COM port, so i have to use the USB to COM port solution. The problem has been that the HRD program, after few minutes goes into "grey" with the message. "NOT RESPONDING" at the top of the window.
My platform is the Windows 7.
Now i have changed the USB to COM port cable, to the one who have the FTDI chip. Then, this problem are solved. In the beginning i used the cable with the proligic chip, which dos'nt work.
After a testing period this is the solution. So, for those who have the same problem, you can use this link:
