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