Diego,
What sort of connection information are you looking for? Are you looking for the RS-485 wiring connection? If so, please see page 2-11 in the FP-1000/1001 Users Manual. It can be downloaded from the following page.
The manual does not contain specific pictures for the RS-485 port on a computer because there are different connector styles for RS-485 ports. Thus it contains the wire names but not a picture of the actual connector.
Regards,
