  15. Hi there,
  16.  
  17. can any one help me with the following problem:
  18.  
  19. I need to connect a DEC computer to a Multiplexer, using a serial line.
  20.  
  21. The DEC computer needs a RJ45, the Multiplexer a DB25-female connector. I
  22. have no idea what cable to use, since I don't know th RJ45 connection. What
  23. I would like is 1-1 connection from the RJ45 to the DB25 connector, the rest
  24. (the part between the DB25 and multiplexer) I can figure out myself.
  25.  
  26. I have a RJ45 connector, a 6-wire cable and a DB25 connector, now all i
  27. need to know which signals (FG-1, TD-2, RD-3, RTS-4, CTS-5,
  28. DSR-6, SG-7, DCD-8, DTR-20) come out of the RJ45, and which is which?
  29.  
  30. Maybe somebody can complete the schema below.
  31.
