I don't know what the FIF-232C box is. Virtually all logging programs I 
know of, including N1MM, are looking for a serial port. That can be a 
"real" serial port, or it can be one generated by a USB to RS232 converter.

The control port in the FT1000MP and others in that series is simply an 
RS232 port, so all you need is a properly wired cable adapter -- DB9 on 
one end, the round DIN on the other. Only two circuits are used -- TXD 
and RXD (pins 2 and 3 on the DB9, with 5 as the return). When I ran MPs 
with WriteLog and later with N1MM, that's exactly what I used. I don't 
know if the FT1000 you have is different. The manual should show pin 
assignments for the FT1000.

If your adapter was working but isn't now, I would suspect a problem in 
one of the connecting cables. The ham market is flooded with junk 
connectors, especially DIN connectors, and the DINs are real crap. Not 
only are the contacts almost impossible to solder to (poor choice of 
metal or plating), but the dielectric melts with even modest amounts of 
heat. REAL DIN connectors cost $5 - $7. Buy from Allied, Newark, etc. 
Brands are Tuchel and Switchcraft. Junk DIN connectors cost a buck.

I tried to make some adapters using DINs I had bought from a popular 
(and respected) ham vendor. Every one I made eventually failed because 
the solder connection fell apart.
