TTL is the electrical signal level. BNC is the mechanical connector. You need to build a cable that has a BNC connector on one end and a DB-9 on the other. You can add the PPS signal to the existing serial cable if you want or use a separate serial port. If your existing cable has a molded plug you can't easily add it. You can either chop the plug off and add a new one, or make an adapter cable with two plugs, one of each sex, merging the PPS in on one end. -- The suespammers.org mail server is located in California.
