That would be the trickiest part... I think that I
should
try wiring the DE9 directly to a 4wire phone cable; it is easier
to find a phone cable than a female DIN8.
This won't work as there are electronics in that box. A TeleNet connector
doesn't just re-pin from a din 8 to a phone wire. Besides, it only uses 2
of the four wires (the yellow/black pair aka "line 2").
You will need to build an adaptor to go from Din 8 to DE 9, or just check
eBay and see if you can find telenet connectors with the DE9 already on
it.
