I have two problems. The first is that I do not own a
"proper" cable that
goes from the DL11-W to a terminal. I own a VT240 and have crafted a cable
that goes from the Berg connector on the DL11-W through a header to a DB9,
which connects to a DB25/DB9 expander on the back of the VT240.
Obviously I've verified the VT240 is in 300/8O1 as required. To go from
the flat-ribbon to the DB9 I have what used to be the header from a CDROM
drive and have soldered the RX/TX/GND lines on the DB9 direct to the pins
on this header. Currently it looks like this:
BERG ? ?DB9
B ? ? ? ?5 ? ?GND
F ? ? ? ?2 ? ?RX
J ? ? ? ?3 ? ?TX
I -think- this is right, but I'm not positive. If I'm doing something
stupid, I'd sure love to have someone point it out.
I built a cable like the adapter you're describing here for a DL11-D
and it looks like the same sort of deal. For a terminal, I think you
want RX and TX the other way around (unless you're using a crossed
cable from your adapter to the terminal, of course). You also need to
connect the "interlock" pins too (E and M for EIA/RS-232).
