We recommend contacting a cable distributor like Black Box and ordering one of their straight-through extender cables. This is far less expensive than having a custom "62-25"-pin cable built. It is also a faster solution, as this cable is fairly common and available in a variety of lengths. Request a cable with all pins attached, with one plug and one socket. You might want to describe the cable length (10 meters plus 3 feet, the length of the "Hydra" cable, which is within RS-232-C specification of 50 feet), and the data rates you intend to use.
