That's why I first began making those MMJ (6P6C
offset) to 6P6C standard
plug cables. People asked me if I could make cables that could be used
Right...
with 6P6C to DE-9 or DB-25 rewirable adapters. I later
had enough demand
for them that I began pre-wiring 6P6C DE-9 adapters as H8751-J work-alike
adapters and pairing them up with a cable. These were moderately cheap for
me to make when buying the materials in bulk and they sold for $15-20 in
my eBay store (which covered my costs, including the stuff people often
overlook such as the eBay listing fees and shipping supplies...that is
until eBay raised their fees through the roof). I actually had a hard time
keeping up with initial demand for those cables and shipped them all over
the world. Note that those DE-9 connectors used crimped pins (AMP) and not
soldered/spliced wires. They are a pain to assemble (even with AMP's own
d-sub pin tooling), but I had zero complaints or returns for defects or
bad connections.
The great advnatage of soldering the wires to the D connecotr is that
it's a lot easier to change them. RS232 seiral interaces and the simular
thing on a DE9 connecotr fornd on soem PCs, are notorious for not doing
what you alwauys expect :-)
I have foudn that if you supply only the 'hard to make' part (in this
case criming the MMJ) and let the user do the rest you may well sell a
lot fewer cables, but those you sell go to the clueful. Who are not going
to complain that the DB25 version of the cable together with a PC printer
head didn't let thenm print on their deskjet or whatever.
My cheap-ish
Multicomp (Farnell own-brand) crimp tool claims to do 'DEC
plugs'. I've never tried it, and have no idea which make of MMJ it likes.
It has woreked fine on every 4p4c, 6p4c, 6p6c aed 8p8c I've thrown at it
though.
Even without seeing it, I would say with 99% certainty that your crimp
tool handles the WE/SS variety and not the AMP/Tyco type plugs. Most all
the "generic" plugs on the market use the WE/SS die nest form, so unless
