The RT Systems USB-63 USB programming cable is designed to work the TS-590 and other certain models.
This USB cable terminates in a DB-9 (F) plug. Now instead of having to purchase a DB-9 female to DB-9 female cable plus a USB to serial adapter,
this cable makes the connection from the radio port to computer without the need for other adapters.
It comes with a Windows driver CD (but not programming software).
It requires Windows 7 (32 or 64 bit), 8, 8.1 (full) or 10. View diagram.
