To connect your MC-580(M) to your computer or laptop, you need an RS-232<>USB cable with FTDI chipset.


RS-232<>USB cables have a chipset in them to communicate with the computer with a proper driver installed, and only with the right chipset will it work.


Also make sure the RS-232 connector is a male, with screws and not nuts, otherwise the connection of the cable will not fit.


This cable for example:

Sabrent USB RS-232 cable FTDI Chipset, of manufacturer Sabrent.
